Battery module with high capacity and low self-discharge rate

Abstract

The utility model relates to the technical field of batteries, in particular to a high-capacity and low-self-discharge-rate battery module which comprises a box body, the interior of the box body is divided into an equipment cavity and a placement cavity, and heat dissipation holes are formed in the top of the equipment cavity, between the equipment cavity and the placement cavity and on the side, away from the equipment cavity, of the placement cavity. A second heat dissipation assembly for conducting primary heat dissipation on the containing cavity is arranged in the equipment cavity, a first heat dissipation assembly for accelerating heat dissipation is arranged at the top of the containing cavity, and a temperature sensor for sensing the temperature of the containing cavity is arranged on one side of the box body. When the battery module heat dissipation box is used, the second heat dissipation assembly is arranged in the box body, in daily use of the battery module, the second heat dissipation assembly conducts heat dissipation on the battery module placed in the containing cavity so as to achieve the purpose of conducting heat dissipation on the battery module, and the temperature sensor and the first heat dissipation assembly are arranged in the box body so that heat dissipation can be conducted on the battery module. When the battery module is in high power, the temperature sensor senses the temperature in the placement cavity and controls the first heat dissipation assembly to be started, so that the heat dissipation rate of the battery module is increased.
