FIELD: transport.
SUBSTANCE: invention relates to electric vehicles and can be used for their production. Vehicle electric drive is cooled with the help of thermal pickups and controllers facilitating the drive working temperature reduction and stabilisation. Heat carrier is cycled in the closed fluid circuit integrating the heat exchange devices into the transfer system. Low-boiling coolant is used as the heat carrier fed at reduced pressure into evaporators combined by traction engine and power controller that allows the rpm adjustment. Coolant pressure is increased to feed it into condensers-radiators and signals supplied from thermal pickups that control the drive and ambient air temperatures are compared. Thermal stabilisation system is used to compare said signals with optimum magnitudes of working temperatures to control the heat exchange in the system to ensure the selected ranges of working temperatures.
EFFECT: lower specific power input, heating of the cabin by the drive heat exchange.
