DEVICE FOR THERMOSTATTING ELECTRIC VEHICLE UNITS Russian patent published in 2019 - IPC B60K11/02 F01P3/20 

FIELD: vehicles.

SUBSTANCE: invention relates to electrically driven vehicles. Device for thermostatting of electric vehicle units comprises radiator (1), pump (2), with output of which there are interconnected liquid-cooling jackets of storage battery (3), traction motor (4), inverter (5) and device (6) for charging accumulator battery (3), hydraulic lines (7–11) communicating said cooling jackets with inlet of radiator (1) and inlet of pump (2). In hydraulic lines (7–10) there are electromechanical cocks (12, 14, 16, 18) controlled by sensors (13, 15, 17, 19) of heat carrier temperature in hydraulic lines (7–10). Electromechanical valve (20) controlled by temperature sensor (21) is installed at radiator inlet (1). Electromechanical valve (24) is installed in hydraulic line (11). Cooling jacket of storage battery (3) is communicated with pump (2) outlet via electromechanical valve (25) controlled by temperature sensor (13). Entry into cooling jacket of storage battery (3) is communicated via additional electromechanical tap (26) with cooler (27) outlet, in series with which electromechanical tap (28) is installed, controlled by temperature sensor (29), and to outlet of liquid heater (30), in series with which electromechanical valve (31) is installed, controlled by temperature sensor (32).

EFFECT: higher reliability of electric vehicles and improved conditions of its operation.
