Temperature control system of an electric vehicle

Abstract

The invention discloses a temperature control system for an electric vehicle including a kettle and a controller; at one end of that kettle, a first water pump is connected, the first pump is connected with a heater, the heater is connected with a three-way valve A, at one end of that three-way valve A is connected with a three-way valve B, at the other end of the three-way valve A is connected with a heat exchanger, the three-way valve B is connected with a heating core, the heat exchanger is connected with a compressor, the compressor is connected with a condenser, the condenser is connectedwith an evaporator, the heat exchanger is connected with a four-way valve A, a battery pack is arranged on one side of the four-way valve A, a four-way valve B is arranged beside the battery pack, the four-way valve B is connected with a motor, the motor is connected with a motor controller, and the motor controller is connected with a charger. The invention has the advantages of having a plurality of working modes, thereby realizing the temperature regulation of the battery system and the transmission system, and ensuring the normal use of the automobile in different environments, and has reasonable structure and strong practicability.

Description

technical field [0001] The invention relates to the technical field of automobile thermal management, in particular to a temperature control system for a complete electric automobile. Background technique [0002] With the development of society, cars have gradually become a necessary means of transportation for every family. At present, the vast majority of cars use gasoline as fuel for driving, and some cars have been changed to gas as power, but whether it is gasoline or gas, In the process of use, a large amount of exhaust gas will be generated, and the direct discharge of exhaust gas into the air will increase the speed of environmental pollution, making our living environment worse. In order to protect the environment, a new type of car that uses electricity as energy has been gradually introduced to the market. The car is equipped with a large-capacity battery, and the engine is driven by electricity to run. Although the electric car is energy-saving and environmental...

[0002] With the development of society, cars have gradually become a necessary means of transportation for every family. At present, the vast majority of cars use gasoline as fuel for driving, and some cars have been changed to gas as power, but whether it is gasoline or gas, In the process of use, a large amount of waste gas will be generated, and the direct discharge of waste gas into the air will increase the speed of environmental pollution, making our living environment worse

In order to protect the environment, a new type of car that uses electricity as energy has been gradually introduced to the market. The car is equipped with a large-capacity battery, and the engine is driven by electricity to run. Although the electric car is energy-saving and environmentally friendly, the battery is in the process of charging and discharging. It will emit a lot of heat, and when the temperature of the battery is lower than 0°C or higher than 50°C, it is prone to failure, which will shorten the life of the battery, so the temperature control of the battery is particularly important

At present, the heat dissipation of batteries in electric vehicles is mostly carried out by radiators. The heat dissipation efficiency is low, and the batteries cannot be heated. As a result, electric vehicles are not suitable for charging and discharging in cold winter, which affects normal use.
