A temperature control system and an electric vehicle

Abstract

The invention provides a temperature regulation system and an electric vehicle, and relates to the technical field of whole vehicle control. The temperature regulation system comprises a driving motor, a heat exchanger, an occupant compartment heating device, an occupant compartment cooling device and a controller, wherein a heat preservation device is arranged at the outside of the driving motor;the heat preservation device can switch between an effective heat preservation state and an ineffective heat preservation state; the heat exchanger is connected to the driving motor; the occupant compartment heating device forms a first heat exchange circuit with the heat exchanger; first switch control elements for connecting or disconnecting the first heat exchange circuit is arranged in the first heat exchange circuit; the occupant compartment cooling device forms a second heat exchange circuit with the heat exchanger; a second switch control element for connecting or disconnecting the second heat exchange circuit is arranged in the second heat exchange circuit; the controller is electrically connected to the heat preservation device, the first switch control elements and the second switch control element; the first heat exchange circuit is connected when the controller is used for controlling the heat preservation device to be in the effective heat preservation state; and the second heat exchange circuit is connected when the heat preservation device is in the ineffective heat preservation state. The solution of the invention reduces energy consumption of the whole vehicle.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and in particular relates to a temperature control system and an electric vehicle. Background technique [0002] As the leading product in the current automobile market, electric vehicles have the advantages of energy saving and emission reduction compared with ordinary gasoline vehicles. However, when there is a demand for heating the passenger compartment, the existing technology uses the heater in the passenger compartment to convert electrical energy into heat energy, providing the occupants cabin heating, which increases the energy consumed by the electric vehicle; and the driving motor of the electric vehicle will generate more heat during the working process. At present, natural cooling is generally used to dissipate heat for the driving motor. Reduced the life-span of described driving motor to a certain extent. How to integrate the heat-generating components with the heat-consum...
