Abstract

The invention relates to the technical field of power batteries, in particular to a battery module. A drainage structure is arranged on the outer side wall of a cover plate; part of water drops on a connecting piece and a busbar flow into the water storage tank of the drainage structure, and water in the water storage tank flows out of the battery module through a first water outlet hole and a second water outlet hole so that the problems of dangerous phenomena of electric leakage, short circuit, fire and explosion and the like of the battery module due to the fact that the nut of the pole andconfluence condensed water drops possibly flow into the battery module are solved.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery module. Background technique [0002] The poles of the battery module are located at both ends of the battery module, and are usually fixed on the end plate of the battery module. The main function is to use the medium for the electrical connection between the battery module and the outside. The connecting medium is connected to the busbar, and the nut and the busbar will generate heat when they are energized. When the battery module is in a low-temperature environment, the moisture in the air will condense on the nut and the busbar to form a ball of water droplets. As the time in the environment increases, the water droplets will condense larger and larger, and the water droplets may flow into the battery module, causing dangerous phenomena such as leakage, short circuit, fire and explosion of the battery module. Contents of the invention [0003] Aiming at ...
