Abstract
A vehicle includes a chassis, a housing to house one or more battery modules, the housing being supported by the chassis, an electric motor to receive electrical power from the one or more battery modules, a liquid cooling system including a radiator to cool a coolant when the coolant flows through the radiator, and one or more coolant pumps connected to the radiator to circulate the coolant, and an air cooling system to cool the one or more battery modules. The air cooling system includes a compressor, a condenser, and one or more evaporator coils, and the radiator and the condenser are located adjacent to each other.
