New energy passenger car carriage and battery centralized heat management system and working method thereof

Abstract

The invention discloses a new energy passenger car carriage and battery centralized heat management system and a working method thereof, and belongs to the technical field of new energy automobile heat management. The system comprises a temperature detection module, a temperature adjustment control module, an air conditioning module and a temperature distribution module. The temperature detectionmodule comprises a carriage temperature detection module and a battery temperature detection module; the carriage temperature detection module and the battery temperature detection module are electrically connected with the temperature adjustment control module. The air conditioner module and the temperature distribution module are both electrically connected with the temperature adjustment control module, the air conditioner module is fixedly connected with the temperature distribution module through a pipeline, independent control over the carriage and a battery compartment can be achieved,common control over a compartment temperature and a battery compartment temperature is achieved too, and waste of heat generated during air conditioner refrigeration is avoided.

Description

technical field [0001] The invention relates to the technical field of heat management of new energy vehicles, in particular to a centralized heat management system for new energy passenger car compartments and batteries and a working method thereof. Background technique [0002] With the development of society and the requirements of energy saving and emission reduction, pure electric vehicles are becoming more and more popular. The discharge capacity and charging speed of electric vehicle batteries have a great relationship with the battery temperature. If the battery temperature is too high or too low, it will cause the failure of the power battery to charge and discharge. Therefore, maintaining the battery of an electric vehicle within a certain range can not only increase the service life of the battery, but also increase the mileage of the electric vehicle and shorten the single charging time of the electric vehicle. [0003] At present, some electric vehicle factorie...
