The prospect of fast charging pit stops for future ABB FIA Formula E Championship races is set to be discussed at upcoming rules meetings to decide on the third generation of Formula E car.
The concept for the Gen 3 car is yet to be fully defined but a move to a smaller battery using different material flows could be an attractive proposition for rule-makers in the championship.
E-racing365 revealed last month that the present iteration of Formula E car is likely to be extended to a fourth season meaning that its final campaign could be the 2021-22 season.
This is when the third generation of Formula E car would begin and one of its leading technical advisors says that the possibility of fast charging pit stops should be further explored.
“First, we have to think about when the future of EV technologies and in terms of fast charging and when it is really coming,” professor Burkhard Goeschel, president of the FIA’s Electric and New Energy Championship Commission, told e-racing365.
“If you introduce charging you asking a lot of things especially in the battery technology. We can use a smaller battery and make the car lighter but for real fast charging you need different electrodes.
At present, silcon carbide electrodes help store energy in the batteries, but if fast charging is to be used for short energy cycles, a shift to more advanced battery technology would need to be made.
“It all means that the electrodes are getting thinner and the energy flow performs better than a classic electrode,” said Goeschel.
“We have not really seriously discussed it yet but in my mind this direction makes sense from the technical side, from the manufacturer value and also from the sporting side.
“A return to pit stops makes sense so that there is a strategic openness in this fifty minutes of a race.
“It is a new technology and we are in a very position with Formula E because everything which is happening here has a direct relationship to sustainable production.”
The next technical working group meeting is set to take place on Dec. 20 at the FIA headquarters in Geneva.
