Problems solved by technology

[0002] Existing electric vehicles generate power through the cooperation of batteries and drive motors. Among them, the battery determines the cruising range of the electric vehicle, and the discharge capacity of the battery is only about 50% of the usual in a low-temperature environment, which makes the cruising range of the electric vehicle large. A decrease in the magnitude affects the user experience

Abstract

The invention belongs to the technical field of electric vehicles, and discloses an electric vehicle heat regulation and control system which comprises a motor loop, a battery loop and a first reversing valve, the motor loop comprises a driving motor, a first water pump and a radiator which are sequentially and circularly communicated through a fluid pipeline, and the battery loop comprises a battery and a second water pump which are circularly communicated through a fluid pipeline. The first reversing valve is respectively communicated with the motor loop and the battery loop, the first reversing valve has a first reversing state and a second reversing state, the motor loop and the battery loop are independent from each other in the first reversing state, and in the second reversing state, the driving motor, the first water pump, the battery and the second water pump form a circulation loop through the fluid pipeline and the first reversing valve. According to the invention, the motorloop and the battery loop are subjected to reversing adjustment through the first reversing valve, so that when the temperature of the battery is too low, the heat of the motor loop can be transferred to the battery loop, the use performance of the battery can be ensured, and the endurance mileage of a vehicle in a low-temperature environment is increased.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a thermal control system for electric vehicles. Background technique [0002] Existing electric vehicles generate power through the cooperation of batteries and drive motors. Among them, the battery determines the cruising range of the electric vehicle, and the discharge capacity of the battery is only about 50% of the usual in a low-temperature environment, which makes the cruising range of the electric vehicle large. The amplitude decreases, which affects the user experience. [0003] In addition, when an electric vehicle is started in a low-temperature environment, due to the small discharge power of the battery and the insufficient power of the motor, the electric vehicle runs very slowly, which seriously affects the driving experience. [0004] In the existing electric vehicles, the motor system and the battery system are independent of each other, and the motor s...
