Useable Energy Reduction Considered for Later in Season

Differing levels of useable energy depending on the characteristics of each circuit might be brought into the ABB FIA Formula E Championship later this season, according to one of the all-electric series’ leading figures.

Frederic Bertrand, the FIA’s director of circuit racing championships, says that altering the amount of usable energy available to cars may be considered in the future.

The current McLaren Applied Technologies battery delivers 52 kWh of usable energy with power capped at 250 kW in qualifying and 200 kW in the race.

During races, drivers have access to an additional 25 kW of power via the new attack mode for a total of 225 kw which is available to be used for a maximum of eight minutes at a time of the drivers’ choosing.

However, the FIA is now looking at adapting different applications of usable energy for different circuits that will be raced on in the remainder of the 2018-19 season.

“We like to make things a little bit challenging, so we might think of changing [the usable energy] sometimes,” Bertrand told e-racing365.

“That’s the reason why we give the attack mode sharing system very late, to try to keep simulation difficult.

“We will probably think of reducing the energy at some races because even here it will be quite tricky to manage it properly with 52 [kWh of usable energy] available.

“You have some races where we could go a bit lower, so that is probably one of the things that we might do.”

Bertrand touched on the variables of having races affected by safety cars or lengthy Full Course Yellow periods.

These often affect the ‘efficiency race’ elements of the events and turn strategic races into full-on sprint races to the line.

“The only thing we cannot manage is as soon as the safety car is entering, or you have a phase of the race where the energy consumption is lower, for sure we have an issue there,” said Bertrand.

“But at the moment that is also the beauty of Formula E that we are all happy to learn a lot every time.

“We only did one race with the new car and we will now learn a lot within the next races. But modifying the level of energy yes, we think of this.”

    Honestly they should get rid off the fanboost and attack mode and use that energy to reach 1 hour race

    As a fan, I don’t want every race to be an identical “fluffy pink bunny slippers” race (thanks Hindaugh and Westbrook). I want some preservation races, some flat-out races, and some races where a faster-but-thirstier car almost dead-heats with a slower-but-efficienter car. I just made up the word efficienter.
