Problems solved by technology

[0003] In the prior art, the motor cooling system used to cool the motor unit and the charging cooling system used to cool the charging unit mainly have two modes: one is that the motor cooling system and the charging cooling system are independent of each other, which leads to the occupation of The space is relatively large; the second is to connect the motor unit and the charging unit in series in a cooling system, and simultaneously cool the motor unit and the charging unit, so that the energy required for cooling the motor unit and the energy required for cooling the charging unit is relatively large. lead to lower energy efficiency

Abstract

The invention discloses a cooling system for an electric vehicle. The cooling system is used for cooling a motor unit and a charging unit of the electric vehicle and comprises a motor cooling branch, a charging cooling branch and a shared cooling trunk, wherein the motor cooling branch and the charging cooling branch are in parallel connection. The motor unit is arranged on the motor cooling branch, and the charging unit is arranged on the charging cooling branch. The shared cooling trunk is serially connected with the motor cooling branch to form a motor cooling loop for cooling the motor unit, and the shared cooling trunk is serially connected with the charging cooling branch to form a charging cooling loop for cooling the charging unit.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electric vehicle cooling system. Background technique [0002] The electric motor is used as the direct power source in the electric vehicle. In order to ensure the normal operation of the motor, it is necessary to effectively cool the motor unit. Generally, a motor unit of a pure electric vehicle includes a drive motor and a motor controller, and a motor unit of a plug-in hybrid electric vehicle additionally includes a generator. In addition, pure electric vehicles or plug-in hybrid vehicles need to be charged when the battery power is insufficient, and the charging unit including the charger also needs to be cooled during the charging process. [0003] In the prior art, the motor cooling system used to cool the motor unit and the charging cooling system used to cool the charging unit mainly have two modes: one is that the motor cooling system and the charging cooling system are i...
