Charging system

The invention discloses a charging system, comprising a photovoltaic power generation module for converting solar energy into electric energy, a power supply access module for accessing the electric energy provided by the external power supply, a charger for receiving the electric energy provided by at least one of a junction module or an AC access module for battery charging, and a photovoltaic control module for determining the complementary electric energy required by the AC power supply access module based on the photovoltaic power supply and the electric energy required by the charger. The charging system is advantageous in that the electric energy output amount of the photovoltaic power generation module and the electric energy output amount accessed by the external power supply canbe effectively coordinated, and thereby photovoltaic power generation can be fully utilized, and waste can be reduced. 本发明公开了种充电系统，包括：光伏发电模块，用于将太阳能转换成电能；电源接入模块，用于接入外部电源提供的电能；充电机，用于接收汇流模块或交流电源接入模块至少之提供的电能为电池充电；光伏控制模块，用于根据光伏供电能
