The invention discloses a motor drive and battery thermal management integrated system and an electric vehicle. The motor drive and battery thermal management integrated system comprises a first driveassembly, a battery pack and a first four-way valve. The first drive assembly comprises a first motor and a first liquid pump. A liquid outlet of the first motor is communicated with a liquid inlet of the first liquid pump through a pipeline, a liquid outlet of the first liquid pump is communicated with a fourth valve port of the first four-way valve through a pipeline, and a third valve port ofthe first four-way valve is communicated with a liquid inlet of the first motor through a pipeline. A motor radiator assembly is mounted on the pipeline between the liquid inlet of the first motor andthe third valve port. A first valve port of the first four-way valve is communicated with a liquid inlet of the battery pack through a pipeline, and a liquid outlet of the battery pack is communicated with a second valve port of the first four-way valve through a pipeline. Multiple battery pack heating modes can be achieved, and the requirements of different working conditions are met.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an integrated system for motor drive and battery thermal management and the electric vehicle. Background technique [0002] In the prior art, the performance of the power battery used in new energy vehicles will be significantly reduced in a low temperature environment, and the charging and discharging capabilities will be significantly restricted. Therefore, the battery thermal management system is particularly important. [0003] In the existing battery thermal management system, the battery heating method generally uses heating equipment such as high-voltage electric heaters or fuel oil heaters, but the cost of components is relatively high, and the heating mode is relatively simple. [0004] In view of this, it is necessary to provide an integrated system of motor drive and battery thermal management capable of heating the battery pack with the heat of the motor, a...
