Patent attributes
One example provides a thermal management system for an electric vehicle including a pump to pump a thermal transfer fluid through a number of circulation loops, an electric heater to heat the thermal transfer fluid, a heat exchanger to expel heat from the thermal transfer fluid, a number of valves, and a number of fluid pathways fluidically interconnecting the pump, heater, heat exchanger and valves. The valves being controllable to a number of different positions to form the number of circulation loops, the number of circulation loops including a battery heating circulation loop extending through the heater for heating a battery pack of the vehicle, a secondary components cooling circulation loop extending through the heat exchanger to cool secondary components of the vehicle, including a motor and a motor controller, and a battery cooling circulation loop extending through the heat exchanger to cool the battery pack.
