Managing the temperatures of the critical components of 
any electric vehicle  is an important task, but when they're
being pushed to the limits in Formula E, it becomes even
more of a performance-limiting challenge.
The main way to stop temperatures spiralling out of control
is by using the high-speed airflow passing over the car
out on track.  As the air rushes into the car's side pods,
it is fed through coolant-filled radiators connected via a system
of pipework to the powertrain's main heat-generating components,
like the motor, the power inverter, the electronics, and of course
the huge lithium-ion battery sat right behind the driver.
Small, electric pumps keep the system circulating, powered by
their own auxiliary battery, taking the hot fluid from the affected areas
and sending it through the radiators to be cooled by the airflow
in a continuous cycle. If temperatures get too high or too low,
the system can reduce performance or even shut down,
so keeping everything within the optimum limits is as crucial
to a fast car as the way it is driven, or its mechanical setup.
