The advantages of lightweight battery boxes compared to standardized battery boxes include: 1. Lighter weight: adopting lightweight design can effectively reduce the weight of the battery box, reduce the overall weight of the vehicle, and improve vehicle energy efficiency and range. 2. Higher energy density: The lightweight battery box adopts advanced materials and processes, which can improve the energy density of the battery, making the energy storage capacity of the battery box stronger and extending the range. 3. Better heat dissipation performance: Lightweight battery boxes usually adopt special structures and heat dissipation systems, which can effectively reduce battery temperature and extend battery life. 4. More flexible design: The lightweight battery box can be customized according to different vehicle models and application needs, making it more flexible and convenient, and can adapt to different vehicle requirements.
