How to quickly and effectively detect early-failure batteries, predict the performance change trend of the storage batteries, improve the performance of the storage batteries and reduce the maintenance workload becomes the important factor in the operation management of the storage batteries.

Therefore, in order to improve the operation and maintenance efficiency of the storage battery pack and solve the technical problem that a power grid accident occurs due to manual misoperation and the like caused by increase of operation and maintenance workload of the storage battery at present, it is necessary to construct a remote capacity checking method.
