Abstract

A temperature control system for an electric vehicle battery box, including a finned tube heat exchanger, an air bubble pump, a control module, a solenoid valve A, a solenoid valve B, a solenoid valve C, a control module, a heater, a temperature sensor and a plate heat exchanger , the heat exchange medium circulating in the temperature control system of the battery box is refrigerant, using the bubble pump, relying on the refrigerant phase conversion heat, reducing pump consumption, small area and high efficiency, combined with the intelligent control module, the temperature of the battery pack system is controlled at Reasonable temperature range, less energy consumption and longer battery life.

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...
