Thermal management system for electric vehicle

A thermal management system for an electric vehicle, the thermal management system comprising:

• a single pump to circulate a fluid;
• a heater to heat the fluid;
• a heat exchanger to cool the fluid;
• and
• at least one valve to control circulation of the fluid, the at least one valve being operable in any one of a plurality of modes, the plurality of modes comprising:
• a first mode to circulate the fluid through a first circulation loop comprising the single pump, the heater and a battery pack of the electric vehicle;
• and
• a second mode to circulate the fluid through a second circulation loop comprising the single pump, the heat exchanger and a motor of the electric vehicle, wherein the second circulation loop bypasses the battery pack and the heater.

A thermal management system for an electric vehicle, the thermal management system comprising:

• a pump to circulate a fluid;
• a heat exchanger to cool the fluid;
• at least one valve to control circulation of the fluid, the at least one valve being operable in any one of a plurality of modes, the plurality of modes comprising:
• a passive battery heating mode to circulate the fluid through a first circulation loop comprising the pump, the heat exchanger and a motor of the electric vehicle, wherein the first circulation loop bypasses the battery pack;
• and
• a full cooling mode to circulate the fluid through a second circulation loop comprising the pump, a heater, a battery pack of the electric vehicle, the motor and the heat exchanger, wherein the heater is deactivated;
• and
• a thermal control unit to control the at least one valve, wherein the thermal control unit is to set the at least one valve in the passive battery heating mode when:
• an operating temperature of the battery pack is less than a maximum threshold temperature;
• and
• an operating temperature of the motor is greater than a cooling temperature threshold.

A thermal management system for an electric vehicle, the thermal management system comprising:

• a pump to circulate a fluid;
• a heat exchanger to cool the fluid;
• a system of fluid pathways, comprising:
• first fluid pathways that perform heat exchange between the fluid, a heater and a battery pack of the electric vehicle;
• second fluid pathways that perform heat exchange between the fluid and a motor of the electric vehicle;
• third fluid pathways for delivering the fluid cooled in the heat exchanger to the first fluid pathways;
• fourth fluid pathways for delivering the fluid cooled in the heat exchanger to the second fluid pathways;
• and
• fifth fluid pathways for delivering the fluid heat-exchanged in the first fluid pathways and the fluid heat-exchanged in the second fluid pathways to the heat exchanger;
• at least one valve to control circulation of the fluid through the system of fluid pathways;
• and
• a thermal control unit to control the at least one valve, wherein the at least one valve is to control circulation of the fluid to bypass the first fluid pathways when an operating temperature of the battery pack is less than a maximum threshold temperature and an operating temperature of the motor is greater than a cooling temperature threshold.
