Abstract
A liquid cooling system includes a radiator to cool a coolant when the coolant flows through the radiator, a first coolant pump to circulate the coolant, a second coolant pump to circulate the coolant, an inverter to be cooled by the coolant, an electric motor to be cooled by the coolant and connected to the inverter, a heat exchanger through which the coolant and another liquid can circulate, an Onboard Battery Charger with a DC-to-DC converter to be cooled by the coolant, and a secondary DC-to-DC converter to be cooled by the coolant. The first coolant pump and the second coolant pump are each connected to the radiator.
