Problems solved by technology

Power battery pack is one of the core components of new energy vehicles, and its quality is the most important factor that determines a company's foothold in the market. At present, in the process of battery pack design, the BMU (battery management unit) is usually installed horizontally at the bottom of the box, with bolts Fixed, the wire insertion hole on the BMU is on one side. During the process of inserting wires into the wire insertion hole, due to the limited space, the operator's sight will be blocked by other parts on the box, resulting in misalignment. Pins, which often cause damage to the pins, cause BMU failures, affect production efficiency, and reduce product quality

Abstract

The present invention provides a power battery pack, which includes a box body and a BMU installed at the bottom of the box body, one side of the BMU has a plug-in hole, and one end of the BMU away from the plug-in hole is connected to the box. The body is hinged, and one end of the BMU close to the plug-in hole is detachably connected to the box body. The BMU installation device in the power battery pack has a simple structure and is easy to operate. In the process of operating the BMU plug-in, it can ensure that the plug and the BMU connector are installed vertically, so as to avoid damage to the pins and improve product quality.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a power battery pack. Background technique [0002] my country is currently in the period of energy conversion of vehicles, and new energy vehicles are increasing day by day. In major enterprises, the safety of new energy vehicles has attracted more and more attention. As one of the core components of the new energy vehicle, the power battery pack is the most important factor determining the company's foothold in the market. At present, in the battery pack design process, the BMU (battery management unit) is usually installed horizontally at the bottom of the box, with bolts. Fixed, the plug-in hole on the BMU is on one side. During the process of plugging the wire into the plug-in hole, due to the limited space, the operator's sight will be blocked by other components in the box, resulting in incorrect insertion. Pins, which often damage the pins, cause BMU failures, affect pro...
