Abstract

The invention relates to an electric vehicle battery box temperature control system which comprises a finned tube type heat exchanger, a bubble pump, a control module, an electromagnetic valve A, an electromagnetic valve B, an electromagnetic valve C, a control module, a heater, a temperature sensor and a plate type heat exchanger. A heat exchange medium circularly flowing in the battery box temperature control system is a refrigerant; heat exchange is carried out through utilizing the bubble pump by means of the phase change of the refrigerant; pump consumption is reduced; the electric vehicle battery box temperature control system is small in area and high in efficiency; by combining the intelligent control module, a temperature of a battery pack system is controlled in a reasonable temperature interval; energy consumption is relatively low; and a service life of a battery is prolonged.

Description

technical field [0001] The invention relates to a thermal management system for a new energy vehicle, in particular to a temperature control system for a battery box of an electric vehicle. Background technique [0002] In order to effectively alleviate the pressure on my country's energy and environment, accelerate the transformation and upgrading of the automobile industry, and improve the international competitiveness of my country's automobile industry, new energy vehicles have developed rapidly in my country in recent years, especially the development potential of pure electric vehicles is huge. New energy electric vehicles mainly rely on a large number of modular battery packs to provide the power required by the vehicle. Under low temperature conditions, it is difficult to charge the battery, and even cannot be charged under extreme conditions. Moreover, the battery capacity is easily attenuated, which seriously affects the performance of the electric vehicle. Under h...
