Temperature control device for improving lithium battery use performance

Abstract

The invention provides a temperature control device for improving lithium battery use performance. The temperature control device comprises a power battery pack, a battery management system, a power circulating system, a temperature measurement system, a charge control system, and further comprises a temperature control system and a heating module, wherein the temperature control system is respectively connected with the temperature measurement system, the power circulating system and the heating module; the heating module is respectively connected with the charge control system and the power circulating system. The temperature control device provided by the invention effectively utilizes synergistic effect of the heating module, the power circulating system and the temperature control system, thereby easily guaranteeing that the lithium battery is located in an appropriate working temperature range; the stability and the service life of the lithium battery are improved; and meanwhile, the cost of the temperature control device is lowered, and the operability in the actual application is improved.

Description

technical field [0001] The invention relates to a temperature control device for a battery box, in particular to a temperature control device for improving the service performance of a lithium battery, especially a temperature control device that enables the lithium battery to be used conveniently and has a long service life under various extreme working conditions. Background technique [0002] At this stage, the rapid growth of my country's car ownership has brought a series of energy and environmental problems while facilitating residents' travel. In recent years, the "smog" and huge energy demand that have continued to appear in many places have given warning to human beings' existing energy consumption patterns. The zero emission of pure electric vehicles is the best way to solve urban traffic pollution at this stage. Batteries are the main energy storage components of electric vehicles, and their performance is closely related to temperature. Compared with other type...
