Abstract

The invention discloses a battery self-heating and heat preserving device. The battery self-heating and heat preserving device comprises a power battery monomer, a heating diaphragm, an aerogel shell,a temperature sensor and a switching circuit. The outer surface of the power battery monomer is coated with the heating diaphragm. The outer surface of the heating diaphragm is coated with the aerogel shell. The temperature sensor is arranged on the power battery monomer, and the temperature sensor is arranged between the power battery monomer and the heating diaphragm. The temperature sensor andthe switching circuit are connected by a signal line. Every two of the power battery monomer, the heating diaphragm and the switching circuit are connected with each other. The switching circuit is used to connect the power battery monomer and the heating diaphragm to form a heating hoop. The heating diaphragm is used to generate heat by the Joule heat effect and heat the power battery monomer bythe heat conduction effect. By adopting the battery self-heating and heat preserving device provided by the invention, batteries can be efficiently self-preheated and kept warm under low temperatureconditions, and the charging and discharging performance of batteries can be enhanced.

Description

technical field [0001] The invention relates to the field of lithium ion battery heating and heat preservation, in particular to a battery self-heating and heat preservation device. Background technique [0002] As the environmental problems and resource problems brought by traditional fuel vehicles are becoming more and more serious, vigorously developing new energy vehicles as an effective way to solve this problem has attracted the attention of all countries. Although secondary battery technology has made some breakthroughs in recent years, how to use batteries efficiently, healthily and safely is still a major challenge; among them, temperature, as a key environmental factor, will affect the electrode reaction rate and The diffusion process will seriously affect the charging and discharging performance of the battery. Therefore, the charging and discharging performance of the power battery will be greatly reduced under low temperature conditions, which has become the mai...
