Battery management systems (BMS) have evolved with the widespread adoption of hybrid electric vehicles (HEVs) and electric vehicles (EVs). This paper takes an in-depth look into the trends affecting BMS development, as well as how the major subsystems work together to improve safety and eficiency.
The EV power battery system consists of hundreds or thousands of cells. The battery packing theory and structural integration, management systems and methods, and safety management and control technologies for power batteries are the keys to the application of EVs. 3.2.1. Power battery packing theory and structural integration
As one of the core technologies of NEVs, power battery accounts for over 30% of the cost of NEVs, directly determines the development level and direction of NEVs. In 2020, the installed capacity of NEV batteries in China reached 63.3 GWh, and the market size reached 61.184 billion RMB, gaining support from many governments.
As a crucial component of EVs, power batteries have become a core part of research and development in the growing market of NEVs. Current, weight, performance, storage capacity, and a lifetime of power batteries are key areas of research that are essential for the continued success of the NEVs market.
On the other hand, it is possible to reduce the production cost of batteries by giving some tax incentives to battery manufacturers or manufacturers of core components of the battery industry based on overall considerations of their production quality, sales performance, innovation ability, customer satisfaction, and other aspects.
In fixed configurations, though, battery system performance is, in principle, limited by the weakest cells, which can leave large parts severely underutilized. Batteries are widely applied to the energy storage and power supply in portable electronics, transportation, power systems, communication networks, and so forth.
