Extreme E operates in extreme conditions, and the biggest challenge that it presents is to do with the course itself. Gade says, ‘The temperature swing at an event can be very extreme, and this presents some unique challenges. For example, if you start in a cold environment, in the morning, if you’ve got a damp surface where it’s had lots of saturation from rain, the ground can be frozen, and by midday, that can be muddy and slushy. The challenge is in that part of it rather than too much temperature management onboard. The biggest heat source comes from the battery and the drivetrain when you’re putting out the power rather than when you’re charging, and the environmental temperature delta is the bit that gives you the cooling. The hotter it is, the more difficult it is to cool the vehicle.
