Problems solved by technology

At present, the management unit in the system generally only has simple battery protection functions, but does not have complete intelligent management functions, such as maximum power point tracking (MPPT) of solar panels, battery charge and discharge process management, battery overcharge protection, over discharge Protection, over-current protection, battery balance management, fuel gauge, battery voltage monitoring, and communication with external intelligent units, etc., so it cannot be an independent intelligent power system and cannot meet the requirements of the current smart grid development
