Description
technical field [0001] The invention relates to a circuit design capable of managing and controlling the charging and discharging of a storage battery, which can convert solar energy into chemical energy and store it in the storage battery, which can be used by loads according to actual needs. The controller has the functions of real-time data acquisition, state monitoring and control, data communication and the like, and belongs to the technical field of new energy applications. Background technique [0002] The energy crisis and environmental pollution have made the application of renewable and clean energy such as solar energy and wind energy highly valued by all countries. Generally, solar energy cannot be used directly. The electric energy generated by the photovoltaic array needs to be stored in the battery before it can be used. Therefore, the charge and discharge controller for solar energy applications has become the core of the solar power supply system. At presen...
