We all have seen electric cars on the street. They look very futuristic and demand a second glance from passers-by. And the convenience… you can drive them in the car pool lane, park and even charge it for free in some places. Great! Their price tag is still an impediment to their large adoption by consumers, though, even if incentives exist in many countries.

Another reason for their slow expansion is the rather low drive range these vehicles offer. The longest range available on the market is 300 km (a little over 186 miles) in real driving conditions. Although this would be sufficient for the usual daily commute from home to office, people have the feeling this is not enough for the few times a year they’ve got to drive 500 km (over 310 miles), like to go celebrate Grandma’s 90th birthday. Well, we don’t call that selfishness - although we think you should visit Grandma more often - we call this range anxiety, or the fear of being short of gas (or electricity in our case). So that’s 300 km you can do before you have got to spend several hours at the charging station to continue on your journey and be on time for Grandma’s cake. You’d better order a three-course meal, with a long coffee, buy some newspapers and hoover the car to occupy your time while the car is charging. Fortunately, there is a solution to reduce your entertainment bill at the service; it is Fast Charging. If we could charge our EV to full capacity in the same time as we fill our gasoline tanks, range anxiety would not be such a problem.

In this blog, we want to explore the complex problem of fast charging with Battery Design StudioTM, understand its implications and see whether there is anything that can be done to remedy this problem.

Imagine finally picking up your new Tesla after months of waiting (popular cars have waiting lists). While counting down the days, you daydream about driving that beauty on the freeways and cruising downtown as the commoners turn their heads to catch a glimpse. The last thing you are going to worry about is if the battery is defective or even ineffective. Yet while often overlooked, the battery is arguably the most important part of the vehicle. But don’t worry; chances are that well before you placed your order, computer-aided engineering (CAE) was used to ensure that the battery of your amazing new car will let you feel like Batman and not a Joker.

The demand for safe and efficient Li-ion batteries has never been as high as it is today. By coupling Battery Design Studio® to HEEDS® MDO, battery manufacturers can intelligently drive their designs through a range of design parameters and operating conditions. This speeds up the design process, facilitates innovation and helps battery designers stay ahead of the competition.
