Temperature control system and method

Abstract

The application provides a temperature control system and method. The temperature control system is applied to an electric automobile. A thermal management controller, a vehicle controller, a heat radiator, an electronic water pump and a water temperature sensor are additionally arranged in a conventional electric automobile, and the heat radiator, the electronic water pump, the water temperature sensor, a charger, an AC-DC inverter, a motor controller and a motor are connected in turn via cooling pipelines. Internal temperature of all the components in the working process of the electric automobile is reduced by utilizing cooling liquid fully filled in the cooling pipelines and fans arranged in the heat radiator. Concretely, rotating speed of the fans and operating duty ratio of the electronic water pump are controlled according to the preset control rules and current temperature of all the components detected in real time so that influence on working efficiency and the service life of all the components caused by over-temperature in the electric automobile can be avoided, and thus safe and reliable working of the electric automobile can be guaranteed.

Description

technical field [0001] The present invention mainly relates to the application field of electric vehicles, and more specifically relates to a temperature control system and method. Background technique [0002] As people pay more and more attention to new energy vehicles, pure electric vehicles that can achieve energy saving and emission reduction have attracted widespread attention. At present, major domestic and foreign automobile manufacturers are actively researching and developing. In the practical application of the electric vehicle, it uses the added charger to charge the high-voltage battery, and converts the high-voltage alternating current into direct current through the AC-DC inverter for the low-voltage electrical equipment of the vehicle, thereby ensuring the normal movement of the vehicle. [0003] However, the applicant found that during the driving or braking of the electric vehicle, the AC-DC inverter will generate a lot of heat during operation, which will ...
