Description

Technical Field

[0001] The utility model relates to a protective cover, in particular to a protective cover for a lithium battery management system. Background Art

[0002] The BMS (Battery Management System) is an important link connecting the vehicle-mounted power battery and the electric vehicle. The BMS collects, processes, and stores important information during the operation of the battery module in real time, exchanges information with external devices such as the vehicle controller, and ensures the safe and reliable operation of the lithium battery system. The requirements for the BMS circuit board are high. If it is directly exposed, it will come into contact with moisture in the air, causing oxidation and short circuit, resulting in the loss of control of the power battery management. To solve this problem, a protective cover for the battery management system is designed to solve this potential safety hazard. Content of the Utility Model

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A protective cover for a lithium battery management system includes an insulating box and an insulating cover. The insulating box and the insulating cover are designed as an integral structure. The BMS management system circuit board is placed in the insulating box, and the unilateral distance between the BMS management system circuit board and the insulating box is 0.5 mm. Convex mushroom heads are provided at the inner corners of the outer side of the insulating cover, and concave mushroom heads for engaging with the convex mushroom heads are provided at the two corners of the insulating box.

[0005] Preferably, the insulating box and the insulating cover are made of a PC protective cover.

[0006] Preferably, the PC protective cover is a transparent protective cover.

[0007] The beneficial effects of the utility model: The structure of the utility model is reasonably designed. The protective cover is made of 0.5 mm thick PC material through the thermoforming process. The material of the protective cover meets the requirements of insulation and anti-static, and the color of the protective cover is transparent. The insulating box and the insulating cover in the insulating cover are integrally designed. The insulating box is used to carry the BMS management system circuit board, and the unilateral gap between the circuit board and the management system is set to 0.5 mm to prevent shaking. Concave and convex mushroom head buckles are provided on the insulating box and the insulating cover, which can be tightly buckled. Description of the Drawings
