New energy car heat management system

Abstract

The invention discloses a new energy car heat management system comprising a driving cab air conditioner module, a motor cooling module, a battery temperature control module, a front end heat dissipating module and a heat management control module. The driving cab air conditioner module, the motor cooling module, the battery temperature control module and the front end heat dissipating module areconnected with the heat management control module. The heat management control module judges whether the requirement is met or not according to the received information of the temperature and humidityof a driving cab, the temperature and humidity of a battery pack, the temperature in a motor and the temperature in a power source cabinet, and controls work of all the modules according to the judgement result. According to the new energy car heat management system, an air conditioner, the motor and a battery can be effectively coupled, meanwhile the controller number is decreased to be one, thus the energy utilization rate can be increased, and the cost can be reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a heat management system for new energy vehicles. Background technique [0002] With the development of society and the promotion of national policies, there are more and more companies and models of electric vehicles. With the improvement of people's living standards, car drivers and passengers have higher and higher requirements for the comfort of cars. The mileage of new energy vehicles is related to the working environment of the battery motor. The battery and motor work under the optimal operating temperature conditions, which can greatly increase the cruising mileage of the vehicle and improve energy efficiency. [0003] The existing air-conditioning system, motor cooling system, and battery temperature control system of electric vehicles are three independent systems that work separately and need to be controlled by three independent controllers. The three systems will h...

AI Technical Summary

Problems solved by technology

[0003] The existing air conditioning system, motor cooling system, and battery temperature control system of electric vehicles are three independent systems that work separately and need to be controlled by three independent controllers. The three systems will have three electronic fans that work independently. Redundancy, separate control is not conducive to management

[0004] Existing new energy vehicles use air conditioners, motors, and batteries to dissipate heat separately for harmful heat management, without causing waste of battery energy, and need to configure separate controllers for air conditioners, motors, and batteries, resulting in high vehicle costs
