Abstract

The invention discloses a wall-penetrating type balanced bayonet joint structure for a battery pack. The wall-penetrating type balanced bayonet joint structure comprises a socket fixedly installed on a battery pack box body, and the socket is provided with an external joint exposed outside the battery pack box body after installation. The wall-penetrating type balanced bayonet joint structure is characterized by further comprises a plug where a plurality of pins are arranged side by side. One end of each pin is in conduction connection with a balancing lead led out by an electrical core, and the other end of each pin has a head portion exposed to the end portion of the plug. The socket also has a plug end which is exposed to the inner surface of the battery pack box body after installation, and plugging holes are correspondingly arranged in the plug end. The wall-penetrating type balanced bayonet joint structure is simple in structure, convenient for assembling, and high in safety. The integral reliability of the product is improved, and subsequent maintenance, mounting and dismounting can be facilitated.

Description

technical field [0001] The invention relates to the field of battery research for electric vehicles, in particular to a battery pack through-wall balanced plug connector structure. Background technique [0002] In modern society, with the improvement of everyone's awareness of environmental protection and the depletion of traditional resources. The research, development and application of electric vehicles are becoming more and more important. An electric vehicle is a vehicle that uses battery charging as the vehicle's power source. Vehicle batteries are generally used by integrating multiple cells into a box to form a battery pack. In the research of electric vehicles, how to prolong battery life and improve battery stability is crucial. [0003] In order to improve the stability of the battery and prolong the service life of the battery, after the battery pack is used up, it is necessary to detect the battery cell voltage and perform equalization correction. The balanc...
