Project Management in Educational Project Groups

Answering a question online, I just found a slide deck I have used in the past. It is about project management and I used it in an educational context where students wanted to develop an autonomous driving vehicle.

The slides show an evaluation what kind of project this is, and what kind of project management could be helpful to use in this context. I compared Waterfall, V-Model, V-Model XT and agile project management.

The slides are German.

Top Solid-State Battery News that will take E-mobility Forward

With the evolution of electric vehicles, a lot of debate has been started on its operational pros and cons along with its manufacturing hinges. Batteries being the powerhouse of electric vehicles, became the pivot of such debates. As of now, the normal practice involves the usage of lithium-ion cells for powering up electric vehicles. This whole infrastructure, spreading over hundreds to thousands of cells makes up for a complete battery pack for electric vehicles. As these batteries are rechargeable and the same ones that are being used in smartphones, so there are chances that this is what made manufacturers pick lithium-ion (Li-ion) batteries. However, as it takes much more power to energize an EV as compared to a smartphone, so the EV battery breakthrough has always been anticipated. Its efficiency, cost, and durability are what called for such anticipation. With the breaking out of solid-state battery news, efforts towards making EV batteries sustainable have ramped up. Though this news is indeed a blessing in disguise for both EV enthusiasts and manufacturers, but there is a need to thoroughly investigate the matter that are solid-state batteries sustainable? To know the answer, keep reading!

What is a Solid-State Battery?

From the manufacturing point of view, solid-state batteries use solid electrolytes and solid electrodes to power up the connected loads, which in this case is an electric vehicle. On the other hand, lithium-ion batteries use polymer gel or liquid electrolytes. This change of the matter, i.e. from liquid to solid, has the high potential to put forward the foundations of EV battery breakthrough. Let’s find out in more detail that how solid-state battery news can prove to lay down the foundations of EV batteries sustainable future.

How Solid-State Batteries can Revolutionize the EV Industry?

Electric vehicles have a substantial role in taking forward the green initiatives of e-mobility. While being solely energized by a battery source, there is no doubt in the expected contribution of solid-state batteries for the EV battery breakthrough. Following are some of the ways in which solid-state batteries are set to revolutionize the EV industry:

  • Charging Time: Depending on the overall architecture and battery size of the EV, it almost takes about an hour to charge an EV battery at the Level-2 charging stations. However, with solid-state batteries taking over, there are estimates that charging time will go below 10 minutes.
  • No Overheating: Since electrolyte will be a solid material, so it won’t get as hot as a liquid electrolyte, like in the case of Li-ion batteries. So, it is highly projected that solid-state batteries will be more heat resistant than lithium-ion batteries.
  • Longer Driving Ranges: Typically, lithium-ion batteries deliver an energy density of around 700 watt-hours per liter (Wh/l). With such energy density, they can deliver a driving range of around 500 km per full charge. However, with the solid-state battery news rolling out, the solid-state battery energy density is expected to stand around 1000 Wh/l. Subsequently, this energy density of 1000 Wh/l will make EVs capable of driving up to 700 km without any need for recharging.
  • More Safety: The typical EV batteries contain liquid electrolytes which pose a greater risk in case of electrolyte leakage or any other associated calamity. However, with the adoption of solid-state batteries, this risk will be mitigated as such batteries contain solid electrolytes. Unlike liquid electrolytes, such electrolytes do not cause any flammable calamity.
  • Compact Size: Usually in the EV, the bottom portion of the vehicle contains battery cells, and to provide more range per charge, more battery cells are needed in the vehicle. Solid-state batteries are doing to be in compact size as compared to lithium-ion batteries. Therefore, more number of battery cells can be placed in the vehicle in lesser space, eventually increasing the range per charge.

In a nutshell, these relevancies for the EV industry itself answer the long posing question of are solid-state batteries sustainable? Indeed, the EV batteries sustainable future with solid-state batteries has been long-waited and it is now set to revolutionize the EV industry.

Latest Solid-State Battery News and Development

Since the realization of anticipations related to EV battery breakthrough via solid-state battery news, a lot of work is being done to forego any of the implications. Every R&D institute, university’s research centers, and companies research units have started ventures to work on EV batteries sustainable research projects on solid-state batteries and answer the primary question that are solid-state batteries sustainable?

Samsung Solid-State Battery

In all such pursuits, Samsung took the lead, as Samsung’s Advanced Institute of Technology (SAIT) has announced that it has developed a solid-state battery which is all set to revolutionize the whole EV industry. According to them, their solid-state battery will cover the distance from Melbourne to Sydney, or vice versa, in one single charge. Not only does the battery’s energy density is improved, but its size has also been shrunk to half. With these developments, it clearly means that without any allocation of extra space to store the battery in EV, the range of EV can be doubled. For example, Tesla Model S currently delivers the range of about 700 km with Li-ion battery. However, if this battery pack is replaced with Samsung’s solid-state battery pack, then it’s range would experience a whopping shift to 1400 km. In addition to this, charging cycles have also been improved. This Samsung developed solid-state battery can be recharged for over one thousand times, which means that it can deliver one million kilometers in its total driving range. As of now, a prototype has been developed so as to assess the performance parameters of this battery. This is why its price has not been announced yet. However, given the compact size, longer life, and enhanced number of cycles, it is indeed going to reshape the future of e-mobility.

Toyota and Panasonic Partnership to build Solid-State Battery

Not only has Samsung contributed to this EV battery breakthrough, another big name in the automobile industry, Toyota, has also played its cards in making EV batteries sustainable. Toyota has partnered with Panasonic to build a solid-state battery prototype. Toyota was all set to showcase its working prototype on the occasion of the 2020 Tokyo Olympics but due to coronavirus, it has been rescheduled to 2021 and so is the revelation of their solid-state battery prototype. It seems as if there are some glitches in Toyota’s design and they took advantage of Olympics games rescheduling for improving their prototype. This insight is validated by the remarks of Executive Vice President of Toyota’s powertrain company where he said that though Toyota has a working prototype, they are still looking for ways to harness the true potential of solid-state batteries.

Conclusion

For years, EV battery breakthrough was a long pending thing. The efforts were not only centered on improving the battery infrastructure but EV batteries sustainable nature was also a very anticipated thing. Lithium-ion batteries are power-hungry, costly and take more space to be affixed in an EV. This bottleneck is what motivated researchers to come up with something that shall take forward the e-mobility and improves the efficiency of EVs. With the solid-state battery news, the rays of hope have been lit to a greater degree. Solid-state batteries have the right credentials to remove all the bottlenecks that were created by the lithium-ion batteries. From decreased space allocation to offering high energy density, solid-state batteries are set to embark on the future of electric vehicles. To the questions that are solid-state batteries sustainable? A simple YES! is a short yet comprehensive answer that is going to be validated very soon.

Home vs Commercial EV Charging – Same Goals, Different Challenges

The wholesome benefits of electric vehicle (EV) cannot be reaped unless associated infrastructure is not put in place. While being less reliant on fossil fuels, EV is a great way to bolster initiatives, such as carbon-free environment. As of now, EV sales make up to 8% of global vehicle sales. This percentage is expected to rise to 1/3rd of global sales by the end of the year 2020. Furthermore, the demand for EVs will grow to such an enormous degree by the year 2030 that they will account for 51% of the auto market. Seeing this trend, automobile manufacturers have pledged to invest $300 billion towards EVs and EV charging infrastructure development. While these developments are very appreciable to their core, but in essence, it indicates towards one sheer gray area which is lethal enough to destroy the novelty of electrical vehicles. This gray area pertains to the EV charging commercial and residential EV charging home issues. This tussle of home vs commercial EV charging is very imperative to be dealt with. To understand this, a quick overview of EV charging can prove to be beneficial.

There are three levels that are prevalent pertaining to EV charging. Level 1 charging is the slowest but most readily available source of EV charging. This typical residential EV charging uses a 110V supply line to charge an EV. Level 2 EV charging is relatively faster than Level 1 and uses a supply voltage of over 200V (typically 220V) to charge an EV. Generally, it can charge an EV at a rate of 12 to 60 miles per hour. Level 3 chargers are the fastest and distinguished EV chargers. Unlike Level-1 and Level-2, they use Direct Current (DC) to charge an EV. Their voltage rating is as high as 800V and charges a typical EV up to 80% in just 20 to 30 minutes. However, as opposed to the other two levels, these types of EV chargers cannot be used as residential EV charging, and therefore, can only be installed as EV charging commercial units.

The Challenges of Commercial and Residential EV Charging

The basic idea behind EV charging commercial and home units seems to be very similar, which in actual is indeed similar. But like any other conflicting thing, there is a thin margin line which emerges as a challenge in the form of home vs commercial EV charging. To have a better understanding, let’s discuss the respective challenges separately. Following are the challenges for both EV charging home and EV charging commercial:

Challenges of Residential EV Charging

Below is the overview of challenges related to residential EV charging:

  • Property Ownership: Property ownership poses a very gross concern for setting EV charging home units. It won’t involve much of a hassle for property owners or homeowners, but those who live in a shared vicinity or multi-tenant building such as apartments, face a lot of hardships in charging their EVs at their place of residence. Such people first of all have to face several regulatory issues, such as the consent of the homeowner or other person using the same building. Secondly, they also have to face an infrastructural limitation where residential properties aren’t equipped with the extra incremental load handling strategies. So, even if a homeowner or other stakeholders permit to charge EVs, regulatory penalties may tend to lose the efficacy of charging EVs at home.
  • Slower Charging: Most of the residences host Level-1 chargers which charge an EV at an extremely slower rate. Typically, a person has to plug his/her vehicle overnight or more than that to charge it fully. While Level-2 chargers are also available for residential EV charging but the associated infrastructural cost bars many EV drivers to either commute to far-flung public charging stations or to rely on slow charging of Level-1 EV chargers.
  • Ampere Rating: It is also one of the major EV charging home challenges. While most of the EVs get charged on the 32A EV chargers, but it has been seen that most of the latest EVs, such as Tesla 3, features 48A EV charging, whereas Chevy Bolt uses a 40A charger to get charged. Since it seems that future EVs will feature more ampere ratings charging capabilities to decrement the charging time. Therefore, it is a very pinnacle challenge for the residential EV drivers to choose such a charging port or infrastructure which shall meet their future EV charging aspirations.

Challenges of Commercial EV Charging

Following is the overview of key EV charging commercial challenges:

  • Demand Charges: It is a very prominent challenge when it comes to commercial EV charging. Once someone sets up commercial EV charging stations, demand charges come as a resistive force. In the form of demand charges, EV charging commercial station owners have to pay a fixed amount per month just for the reason that a large amount of energy is at their disposal. Consequently, this cost is passed on to the customers which ultimately results in the costly EV charging for the end consumer.
  • Bureaucratic Hurdles: For setting up an EV charging commercial setup, a person has to experience a lot of bureaucratic hardships. From import duties to getting permissions and licenses, there is a lot involved for the person who pursues the establishment of a commercial EV charging station. Subsequently, it increases the overall time frame to establish a commercial EV charger, and therefore, depreciates the morale of those who are interested in widening the spread of EV charger network.
  • Location: It is one of the most common as well as most talked EV charging commercial challenges. It is said that 95% of EV charging occurs at home. It is also due to the reason that commercial EV charging stations aren’t located near to the load centers or the locality where sheer demand of EV charging ports exist. People are becoming immune to the residential EV charging and this trend is depreciating the cause of increasing public or commercial charging stations.

Conclusion

The growth of EVs is highly dependent on the implacable enactment of residential EV charging units as well as EV charging commercial stations. Amid home vs commercial EV charging tussle, the sheer global commitment towards reducing the carbon emissions will hamper. This can only be avoided if challenges are mitigated with clarity and sound strategy. The implications of EV charging home units are very easy to mitigate by promoting the culture of public charging. However, those who still want to charge their EVs at home and want to mitigate the challenge of ampere ratings, it is advised to equip residential charging with a 40A charger. On the other hand, challenges related to commercial EV charging will need to be dealt with stringent measures too. The viable solution is to proceed with the multidisciplinary approach of easy processing and promoting people to opt for commercial charging. In this way, the process of establishing the commercial EV charging station will be eased up along with the un-burdening of the residential electrical network. In either way, the private sector will come forward to establish EV charging stations on their own with their attractive sales and advertising mechanisms. This will ultimately result in increased EV charging stations, boosting commercial activity, meeting the carbon emission goals, and easing the life of those who own EV and couldn’t charge them at home due to being in the shared vicinity.

EV Performance Optimization for Mobility Bottleneck Removal – A 2020 Perspective

Electric vehicles define the future of mobility. In the times when the whole world is facing shrinking of global oil reserves, the electric vehicle seems like a beacon of light for future mobility. Realizing the relevance of EVs in the future, many countries have already taken keen steps to make EVs a norm in society along with efforts on EV performance optimization. Furthermore, the emerging popularity of renewable energy sources, mainly solar energy, is also complementing EVs. The demand or popularity of EVs in the future can be guessed from the statistics, where China has the highest number of EVs with 3.3 million units. On the other hand, the US is the second-biggest EV market with 1.4 million units. It is being forecasted that by the year 2025, the EVs will capture 84% of the Chinese market share. Obviously, this motivates other nations especially the US and European nations to ramp up their EV reliance, thus leading to the sheer demand of EVs including advancements in EV performance and charger optimization.

But there is a point to ponder whether our current infrastructure and EV technology are rich enough to sustain such emerging demands? Do our mobility network and EV performance parameters are capable enough to welcome such a huge number of EVs? There is a need to look for EV charger optimization so as to not worsen the situation of the mobility bottleneck. Furthermore, it is also imperative to cater to EV performance optimization so that forecasted benefits both from environmental as well as financial perspectives can be capitalized. It must be cleared that the mobility bottleneck is nothing like a conventional traffic jam. Instead it such a localized type of traffic choking where disruption is caused by way of some physical constraints such as road construction, closure of specific lane, and poor mobility or transport infrastructure. Let’s try to establish this matter of correlation in more detail.

How EV Performance Optimization can be seen in the 2020’s Perspective?

Seeing through the EVs in 2020’s perspective is very important. First of all, it is the start of a new decade, the strategies made this year shall have long-lasting effects towards meeting our 2030 goals, provided this consideration is made. Secondly, but most importantly, 2020 is also a year of pandemic and economic recession. In the near history, the world hasn’t experienced what has been experienced now. So, this new world order provides us with a platform to revamp our strategies and move more sustainably towards the future. Therefore, the 2020’s perspective is very pivotal in this sense. In continuation of this, there are two key areas for EV performance optimization in the 2020’s perspective:

EV Charging Optimization

EV charging optimization is one of the main constituents of EV performance optimization. While a prominent number of EVs are forecasted to be penetrated into the system, there is a need to look forward to potential issues related to EV charging and their impact on the overall power system or national grid. In the situation when 50 million EV units are expected to roll out by the year 2025 and about 125 million by the year 2030, there is a chance of substantial impact on national grids. Furthermore, to entertain such a large number of EVs, both charging infrastructure as well as power systems, should be stern enough to meet consumers’ demand. There is a chance of harmonic distortion which may further lead to deteriorating power quality. This implication may affect both EV users as well as domestic electricity users. Since level 1 EV chargers are slow chargers so they require EVs to be connected overnight. This overnight EV charging penetration will lead to the disturbance in the peak load curve. Both of these factors lead to the loss of cost-benefit as consumers will pay more by facing penalties owing to lowering the power quality along with more electricity consumption during peak times.

The above-mentioned implications can be dealt with the employment of EV charging optimization strategies. Ideally, this implication can be dealt by increasing the network capacity or providing power to the EV charging stations from the designated power grid. In this way, harmonic distribution and power quality deterioration will be reduced to a much greater degree. Even if any such condition arises, it won’t affect the regular domestic or industrial consumers. Moreover, EV charging optimization can also be ensured by appreciating the installation of charge controllers in the EVs. Such charge controllers prevent any peak power prices thus leveraging EV users to maintain the cost-effectiveness of EVs. Another approach to achieve EV charging optimization is to make use of smart charging mechanisms where the mode of EV charging is handled by the electricity utility or the EV charging station. This system can either be centralized or decentralized, as per the demand of EV in that particular vicinity.

Energy Efficiency

The energy efficiency of electric vehicles is another important determinant of EV performance optimization. This is the only factor that has substantial contribution towards cost-benefit and high-grade performance. To achieve energy efficiency, EV’s weight constraint has a major role. Lighter the weight, less will be energy consumption from batteries, as EV motors won’t have to exert more power to perform their respective functions. This will enable EVs to drive more without altering the battery capacity. For example, if heavyweight EV could go up to 350 miles in one full charging, then the light EV of the same specs can go up to 400, or in other words, substantially more than that of heavy-weighted EV. However, this should not be perceived as analogous to choosing lighter materials. Instead, this point enables engineers to remove material while keeping the strength and stiffness of the EV intact as per the standard comfort and safety guidelines.

Electric vehicles with four independent electric motors on each wheel are another way to achieve EV performance optimization. There are three reasons due to which such methodology can prove beneficial for yielding expected energy efficiency. First of all, the absence of mechanical links dismisses the probability of friction loses and makes sure that all four wheels work independently. Secondly, independent motors ease the implementation of certain control strategies such as traction control, antilock braking system, and vehicle stability control. Thirdly, the respective energy characterization of each of these motors will provide a better way to control them, thereby amounting to energy conservation and so does the optimized performance.

Mobility Bottleneck and EVs

Mobility bottleneck is going to be a serious concern for future mobility. While EVs seem to be a feasible solution both from financial as well as environmental perspective. But these benefits could go in vain if considerations related to EV performance optimization are not held in place. EV charging optimization has a considerable role in curtailing mobility bottleneck. Since EVs take a lot of time to charge, so in a condition where fast charging capabilities are not enacted, our highways will experience serious mobility bottleneck as a lot of EVs will have to wait in the queue to get recharged. Furthermore, mobility bottleneck will result in more waiting times which further result in discharging the batteries without even stretching through a mile. This will lead to more charging time, long waiting queues, and most of all, a higher cost in terms of charging a vehicle. All these characteristics will result in losing the cost-benefit of EVs. On the other hand, energy efficiency can result in more driving ranges, thus giving more leverage to EV batteries to sustain for a longer time. Consequently, it will result in less discharging times and letting people commute more in a single full charge.

In a nutshell, both of the above measures are quite rich in their respective essence and are thus very pertinent to be adopted. With these measures, not only will mobility bottlenecks be removed, but the efficiency and the cost-saving aspect of EVs can also be ensured.
