Outline
The integration efficiency and energy density of power batteries are the key factors affecting the improvement of the driving range of electric vehicles. Selecting the appropriate power battery integration technology can not only improve the integration efficiency and energy density of the battery system, but also help reduce the costs of the entire vehicle. Focusing on the development trends of power battery system, this paper summarizes 3 key integration technologies of power battery systems: typical integration, module-free integration, and one piece integration. Elaboration is conducted from the technical realization, advantages and disadvantages, application trends. The conclusion and prospect from elaboration show that the power battery system is accelerating towards the trend of less components and more integration. The breakthrough of power battery system integration technologies will bring the vehicle better power, economy, higher driving range and better user driving experience.
