Problems solved by technology

If the accumulation of heat causes high temperature points inside the battery, when the temperature is too high, it will lead to the destruction of the surface electrolyte (SEI) film of the lithium battery, thereby reducing the charging efficiency, shortening the battery cycle life, and may cause thermal runaway, explosion and other safety hazards of the battery. The heating problem of lithium batteries has become an important factor restricting its application and development
[0003] However, there is currently no device on the market that provides constant temperature charging or a constant temperature environment for batteries

Abstract

The invention relates to the technical field of charging equipment, and relates to a battery constant-temperature charging device. The battery constant-temperature charging device is characterized bycomprising a box body and a box cover. The box body is formed by laminating an inner box body and an outer box body. A gap is formed between the inner box body and the outer box body. A built-in charging hole is formed in the inner box body. An external wiring port connected with the built-in charging hole is formed in the outer box body. The battery constant-temperature charging device further comprises a cooling system. The cooling system comprises a cooling liquid inlet arranged on the outer box body, a cooling liquid outlet and a flowing channel for allowing the cooling liquid to flow fromthe cooling liquid inlet to the cooling liquid outlet through the flowing channel. The flowing channel is formed by the gap between the outer box body and the inner box body.

Description

technical field [0001] The present invention relates to the technical field of charging equipment, and more specifically, to a battery constant temperature charging device. Background technique [0002] In recent years, my country has gradually become the largest producer and consumer in the battery industry. After the advent of the information age, the demand for mobile phones, portable computers and some portable entertainment devices has increased sharply, providing a broader market space for the battery industry, and the emergence of electric vehicles has provided opportunities for the development of the battery industry. Taking lithium-ion batteries as an example, lithium-ion batteries have high energy density. In the process of charging and discharging, accompanied by various chemical and electrochemical reactions and material transport processes, some reactions still proceed in the case of an open circuit. These processes will Cause heat generation, the heat generate...
