Abstract

The invention discloses a separated type battery thermal management system, a use method of same, and a quick charging system. A battery system includes a plurality of battery modules and a heat exchange structure which is used for flowing of a heat exchange fluid and is located between the battery modules; a heat exchange loop is established by the external cold / heat supply system and the batterysystem via a connection apparatus so as to perform heat exchange to every battery module by means of the heat exchange loop and the heat exchange fluid stored in the external cold / heat supply system;an external thermal management control device is respectively communicatively connected to the battery system, the connection apparatus and the external cold / heat supply system, thus controlling operation of the connection apparatus and the external cold / heat supply system. The separated type battery thermal management system is low in cost and easy to manufacture, has good cooling effect, is flexible and reliable, has large available range and is high in utilization rate, and can effectively solve difficult problems of thermal management, such as high capacity, high rate and gradient utilization of the battery system.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a separate battery heat management system, a method for using the same, and a fast charging system. Background technique [0002] Temperature has a great impact on all aspects of battery performance, which in turn affects the performance of the battery system. For example, the impact on battery performance such as capacity, power, and safety. Too high temperature, too low temperature and too large temperature difference are not conducive to the performance of the battery. In order for the battery system to operate stably, safely and efficiently for a long time, it is necessary to configure a thermal management system. [0003] The design of the battery thermal management system, in general, is to use one or more thermal management technologies to organize the internal and external thermal loads of the battery according to the requirements of the battery operation and...
