Battery pack is the core energy source of new energy vehicle, which provides driving power for the whole vehicle.

As the carrier of the battery module, the battery enclosure plays a key role in the safety and protection of the battery module.Its appearance design mainly from the material, surface corrosion prevention, insulation treatment, product identification and other aspects.

To meet the requirements of strength and stiffness and the design requirements of protection grade IP67 of electrical equipment shell and provide collision protection, the battery module inside the box takes root in the bottom plate, and the wiring harness is reasonable, beautiful and reliable.

1. General requirements
(1) it has the convenience of maintenance.
(2) in case of vehicle collision or spontaneous combustion of battery and other accidents, it is advisable to consider the structure or protective measures to prevent fireworks, liquid and gas from entering the carriage.
(3) the battery box shall be equipped with nameplates and safety signs, leaving enough space and fixed foundation for the installation of insurance, power line, acquisition line and various sensing elements.
(4) all non-polar basic insulated connectors, terminals and electrical contacts shall be strengthened for protection.After connecting parts, terminals and electrical contacts are connected, they should meet the requirements of gb4208-2008 protection grade 3.

2. Appearance and size
(1) there are no obvious scratches, deformation and other defects on the external surface, and the surface coating is uniform.
(2) the parts are fastened reliably and free from rust, burrs, cracks and other defects and damages.

3. Mechanical strength
(1) vibration resistance and impact resistance. After the test, there should be no mechanical damage, deformation or loosening of the fastening parts, and the locking device should not be damaged.
(2) the battery box fixed by the locking device shall be adopted. The locking device shall be reliable with anti-misoperation measures.

4. Safety requirements
(1) after the test, the protection level of the battery box shall not be lower than IP55.
(2) electric shock protection of personnel shall meet relevant requirements.

After completing the design of the whole power battery system, the completed power battery system must pass the bench performance test to verify whether it meets the design requirements.
