Next Generation Formula E Battery Completes First Race Simulation For Season 5

Getting ready for Formula E season 5 – new look, new battery

The new battery that will be the lynchpin of the next generation of Formula E cars went through its first full race simulation test earlier this month.

The McLaren Applied Technologies-supplied battery, which will see energy almost doubled to 54kWh and last an entire race distance, underwent the crucial test after months of single cell and module cell testing earlier this year.

Professor Burkhard Goschel, who is President of the FIA’s Electric and New Energies Championships Commission, told in Paris last weekend that progress was being made with the battery but that the aggressive timeframe of the planned track testing of the unit will be a challenge.

“It is proceeding well, but we know that it is tight time wise and we will see this summer where we are at the end, but all signs which are coming out are looking positive,” said Goschel.

“We made some first tests. There have been two samples at the end where [the cells] stayed at the same energy content with 54kWh and so it looks positive in this way, but there are still a lot of things to do.”

“It [a full simulation] has been done and it shows up as being very positive and we can show that simulation is nearly the same reality. We still have some issues and with the timing, we just have to get ready with the main issues with the functional testing.”

Goschel also confirmed that the biggest challenges centred around the battery will be cooling and weight.

“One issue always with the battery and the electrical drive is the cooling because the load in our case is a very, very strong one,” he said.

“We will be re-charging very deeply and the inner-resistance goes up and the requirement for cooling is going up. From the first season we have managed it, and I think we can manage it now too.

“The [weight] is getting tight. Because we have had some additional cells to meet some additional requirement which came up so we added some. We are under pressure with the weight, this is true.”

Goschel also confirmed the power that will be available to the drivers from season five to be 200kW for the race and 250kW for qualifying.

We understand that the new generation battery will have a significantly greater energy density as it uses a large number of small format cells, rather than a smaller number of large format cells as is in the current Williams Advanced Engineering supplied-unit.

The cell number within the new battery is believed to be at the 209 mark, which is an increase of 44 cells over the first generation of battery.

McLaren Applied Technologies’ Anthony Law will be the engineering lead for the Formula E project. Law joined McLaren from automotive company Ricardo in 2010.

    The Concept Design of these new Formula E cars looks astonishing. Very sexy, very futuristic and very emotional. Really love it. The new almost twice as big battery may be good for a full race. But when the car is a little heavier they might have to cut one round.

  2. Nada says:

    If I rember right season five will be the first season where Mercedes, BMW, and Audi are suporting factory racing teams…
    That esentialy means Formula E (and EV racing) has made it from a comcept to acceptance…

  3. Timothy Vollmer says:

    I’m excited for season 5, no more car switches, both for what it means technologically and because the car switching I think hurts the series from a public perception standpoint.

    Even more so than that, I’ll really be excited for someday letting the teams develop their own batteries. That’s when we’ll really seem innovation, and potentially a big strategy difference with some teams opting for heavier, more powerful batteries, while others go for light weight and efficiency.

    The car switching has always been a joke and a disservice to EVs in general. Hopefully they can do away with that now, or at least they should drive two shorter sprint races with twenty minutes top-up time or a battery swap in between.

      It’s the same thing as refueling in F1 some years ago. I don’t mind.

    Yey for (more) proper body work and an appropriate sized battery finally! Two out of my three big gripes addressed!

    Now if they just get rid of the stupid “Fan Boost” I’ll be watching every race. I just can’t stomach the idea that the most popular guy (or in reality, whoever the series wants to manipulate to get it) gets and advantage – such a stupid idea, I don’t know how it’s survived three seasons. I want to watch racing, not participate in a popularity contest. It totally de-legitimizes the entire concept (contrary to this site’s stance on it). Until they fix this, it’s just the WWE of racing – not a real sport. Since they keep doubling down on this garbage, I can only hold out hope for the GT series to be interesting.

    1. John says:

      Boohoo! Fan boost doesn’t change anything. I think it’s cool. Go watch F1 if you hate new things.

    2. jdbob says:

      Fanboost has been decreasing in usefulness as time goes on. In season 1 it could be used in both cars. As far as I can tell this season it’s only available in the 2nd car, and only when battery capacity is 50% or above. So it’s only useful 1/4 of the time compared to season 1.

      Amazing what some people will get worked up about.

  6. Mikael says:

    The cars going into the pit to change tires and/or fuel the car (or swap the car) has always been a favourite part of F1/FE racing to me.
    I want pit stops. It gives you strategies and superfast teamwork.

  7. Jake Brake says:

    I thought they were going with a lucid designed pack using 21700s? Which would put it closer to 3200 cells…
