Pure EV and hybrid batteries get hot and require a cooling system that, much like a typical internal combustion engine requires a cooling fluid that may need topping off occasionally. Add coolant to the system as soon as possible.
The elongated battery seen in the second image is often, but not always, used to differentiate from the 12-volt start battery,
It appears as a more traditional automotive radiator in yellow/amber/orange.
Driving without sufficient amount of coolant for a prolonged period of time can cause serious problems with a vehicle’s electrical equipment or the high voltage battery itself.
