THERMOSTAT CONTROL DEVICE OF ELECTRIC VEHICLE UNITS Russian patent published in 2018 - IPC B60K11/02 F01P3/20 

FIELD: electrical equipment; transportation.

SUBSTANCE: invention relates to electric vehicles. Device for thermostat control of an electric vehicle contains a pump (1) with electric drive for supplying heat-transfer fluid from the radiator (2) to the liquid-cooling jackets of the battery (3), traction motor (4), inverter (5), device (6) for charging the battery (3). In the hydraulic lines (7, 10, 13, 16), communicating the said cooling jackets to the radiator input (2), taps (8, 11, 14, 17) are installed, controlled by sensors (9, 12, 15, 18) of the coolant temperature in the indicated hydraulic lines. At the output from the radiator (2) a valve (19) is installed, controlled by a sensor (20) at the input to the radiator (2). Input to the cooling jacket of the battery (3) communicates with the pump (1) through a valve (21) controlled by a temperature sensor (9) at the output of the cooling jacket of the battery (3). Input to the cooling jacket of the battery (3) communicates with the output of the cooler (22) of the heat carrier through a valve (23), controlled by the output temperature sensor (24) of the cooler (22), and through a check valve (25) and communicates with the output of the electric heater (26) coolant through the check valve (25).

EFFECT: increasing in the reliability of the electric vehicle units is achieved.
