A power battery module temperature control system for new energy passenger cars

Abstract

The invention discloses a power battery module temperature control system for a new energy coach, which comprises a battery module, wherein the battery module is connected with a battery management controller through a temperature collecting wire; a battery inlet air guide hood is fixed on one side of the battery module in a sleeving manner; a battery outlet air guide hood is fixed on the other side of the battery module in a sleeving manner; a heating panel and a vortex pipe are fixed at the inlet of the battery inlet air guide hood; a vortex pipe is sequentially connected with a blast pump and a motor through a corresponding electromagnetic valve. According to the power battery module temperature control system for the new energy coach, based on the integral heat management and control of the whole coach, the compressed gas output from the blast pump and motor cooling water heat in the moving coach are mixed as an energy source; the cold gas and hot gas are provided for the battery through the vortex pipe and the heating panel; the temperature control of battery module is realized; the requirement that the battery can work in an optimal temperature range in a cold winter and in a hot summer is satisfied.

Description

technical field [0001] The invention relates to the field of design and manufacture of new energy vehicles, in particular to a power battery module temperature control system for new energy passenger vehicles. Background technique [0002] With the continuous deterioration of our country's natural environment, more and more smog weather has seriously affected our living environment. Therefore, the country's requirements and policies for energy conservation and emission reduction are also unprecedentedly increased. In the field of automobiles, for New energy buses with remarkable effects in energy saving and emission reduction have become national key promotion products, but an important factor restricting the promotion of new energy buses is that the service life of vehicle power batteries is too short. How to prolong the service life of vehicle power batteries has become a It is a fundamental condition for accelerating the promotion of new energy bus and automobile products...

AI Technical Summary

Problems solved by technology

[0004] At present, domestic mainstream battery manufacturers use resistance wire heating or passive insulation protection in the structural design of vehicle power battery modules; battery cooling adopts a series of cooling measures such as ventilation cooling, liquid cooling, and solid cooling; due to liquid, Solid-state heat dissipation methods all have hidden dangers of electric leakage and water leakage, and the structure is complicated and bulky, which is difficult to use on cars

Therefore, the vehicle power batteries on the market generally adopt ventilation cooling and passive heat preservation protection, but this temperature control method is greatly affected by the external environment temperature. When the external air temperature itself is too low or too high, the temperature of the battery module will be difficult. It is controlled and limited by the structure of the whole vehicle. The internal air duct structure of the battery module cannot well ensure the consistency of heating and heat dissipation of the monomer.
