Reconfigurable battery systems: A survey on research challenges

In recent years, China is vigorously developing clean energy, and battery packs composed of multiple lithium batteries are important energy storage components, which are used in robots, renewable energy systems, energy storage in smart grids and electronic vehicles. In order to reduce the safety risks caused by the failure of a single lithium battery and improve the utilization efficiency of the battery pack, it is very important to design a good reconfigurable circuit. Reconfigurable battery packs can solve some problems existing in traditional batteries, and reasonable use of reconfigurable batteries can extend battery life and avoid the impact of battery failures. Reconfigurable batteries are getting more and more attention because of their practicality.
