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 invention provides a power battery pack. The power battery pack comprises a box body, and a BMU at the bottom of the box body, wherein one side surface of the BMU is provided with a plug wire hole; one end, far away from the plug wire hole, of the BMU is hinged to the box body; one end, close to the plug wire hole, of the BMU is detachably connected with the box body. A BMU mounting device in the power battery pack is simple in structure and easy to operate, can ensure the vertical installation of a plug and a BMU adapter in the BMU plug wire operating process, and avoids the damage of a contact pin, and meanwhile, the product quality is improved.

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 vehicle energy conversion, and new energy vehicles are increasing day by day. In major enterprises, the safety of new energy vehicles has attracted more and more attention. 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 in turn often cause damage to the pins, caus...
