Williams Advanced Engineering and Rimac Automobili are among the candidates to become the sole battery supplier of the FIA Formula E Championship in season three and four, ElectricAutosport.com can reveal.

The 200 kW batteries that are being used in the first two seasons are supplied by Williams. The British engineering firm received the task only one year until the start of the inaugural season. They designed and built a prototype in six months and tested and built the remaining batteries just in time. This outstanding performance and reliable power units were well received.

Rimac Automobili is best known for its Concept_One 1088 hp electric supercar, which is currently featured in the series as the Race Director’s vehicle. The Croatian manufacturer is building an impressive track record as it, for example, supplied the battery-pack for the Koenigsegg Regera. Rimac managed to develop, for Koenigsegg, a 9,27 kWh battery to deliver 500 kW. With a weight of just 115 kg, the package delivers 4,35 kW per kilogramme. Not long ago Rimac built the 1100 kW race vehicle for Nobuhiro Tajima to compete in the Pikes Peak International Hill Climb.

As ElectricAutosport.com revealed earlier, Formula E’s provisional roadmap is likely to feature a 32 kWh battery in season three and four that will probably gain 50 kW power to 250 kW of maximum power output. It is likely that the participating teams can build and race their own battery from season five onwards.

The organisation and the ten teams are currently in discussion to select a battery supplier. To design a completely new power unit can take up to 16 months. In that perspective, a decision should be made soon.

  1. I and most people I have spoken to, realize that the performance of the batteries dictates the performance of the cars and would rather see development on the batteries, then any other part of the car. If they could increased the batteries to 56kWh they could ditch the car swapping or have a real reason to develop a new 350kW electric motor. I know that cost control will be used to justify the development plan that they are on but, I hate explaining that the reason the cars look slow is because they only have the equivalent of about 7 liters of petrol for the race. They are then impressed by any car traveling 80km at 100kmh with only 7 liters of petrol! Efficiency is not the series’ problem, they have that in spades. What they really need is more power (or fuel) on board the car, allowing the drivers to really start to push in the cars!
