Abstract

The invention discloses a battery self-heating heat preservation device. The battery self-heating and heat preservation device includes: a power battery cell, a heating diaphragm, an airgel shell, a temperature sensor and a switch circuit; the outer surface of the power battery monomer is covered with a heating diaphragm; the outer surface of the heating diaphragm Covered with an airgel shell; the temperature sensor is set on the power battery unit, and the temperature sensor is set between the power battery unit and the heating diaphragm; the temperature sensor and the switch circuit are connected through the signal line; the power battery unit, the heating The diaphragm and the switch circuit are connected to each other in pairs. The switch circuit is used to connect the power battery unit and the heating diaphragm to form a heating circuit; for heating. The battery self-heating and heat preservation device provided by the present invention enables the battery to be efficiently self-preheated and heat-preserved under low temperature conditions, thereby improving the charging and discharging performance of the battery.

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...
