Problems solved by technology

[0003] The current battery pack structure for electric vehicles is complex. The battery modules and electrical boards are separated, that is, they are installed separately, and the installation layout is generally installed in parallel. This method takes up a relatively large space. After the electrical board is fixed, it is necessary to continue to install the collection and monitoring wiring harness, which often has a high probability of misoperation and low work efficiency, which is not conducive to manufacturing and installation

Abstract

The invention provides a battery pack structure for an electric vehicle. The battery pack structure for electric vehicle comprises an opening at one end and a box body closed at the other end, a battery module is installed in the box body, the box cover is buckled on the box body and fixedly connected by bolts, positive and negative terminal posts and communication output ports are arranged on the box cover, an electric board is also installed in the box body, and the electric board is fixed on the battery module group and electrically connected with the battery module group; The battery module is provided with a plurality of collection terminals for detecting voltage signals and temperature, and is insulated by a collection cover plate. The collection terminals are connected with the electric appliance plate through a collection wire harness, and the lead-out wire harness on the electric appliance plate is connected with positive and negative terminal posts and communication output ports on the box cover. The invention adopts an integrated design, has strong manufacturability, small occupying space, low probability of misoperation, and greatly improves installation efficiency.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack structure for electric vehicles. Background technique [0002] With the development of electric vehicles, the requirements for the manufacturing process of power batteries are getting higher and higher, but the manufacturing cost is being greatly reduced, which requires the development of power battery manufacturing in the direction of standardization and automation. [0003] The current battery pack structure for electric vehicles is complex. The battery modules and electrical boards are separated, that is, they are installed separately, and the installation layout is generally installed in parallel. This method takes up a relatively large space. After the electrical board is fixed, it is necessary to continue to install the collection and monitoring wiring harness, which often has a high probability of misoperation and low work efficiency, which is not conduciv...
