The invention discloses a charging device, which is applied to a charging system adopting a photovoltaic module and a power grid for combined power supply and comprises a photovoltaic charging module, a direct current charging module, a control module and a power distribution module. Charging energy of the charging device comes from a photovoltaic module and a power grid, and charging currents provided by the photovoltaic module and the power grid for to-be-charged equipment are controllable, so that the charging currents provided by the photovoltaic module and the power grid for the to-be-charged equipment are reasonably regulated and controlled according to the charging current requirement of the to-be-charged equipment, therefore, the required electric energy is provided for the to-be-charged equipment, the total charging current fluctuation of the to-be-charged equipment is small, and the charging reliability is high. The invention further discloses a charging method and system which have the same beneficial effects as the charging device.
本发明公开了一种充电装置,应用于采用光伏组件和电网组合供电的充电系统,包括光伏充电模块、直流充电模块、控制模块及功率分配模块。充电装置的充电能源来自于光伏组件和电网,且设置光伏组件和电网提供给待充电设备的充电电流可控,以实现:根据待充电设备的充电电流需求,合理调控光伏组件和电网分别提供给待充电设备的充电电流,从而为待充电设备提供其所需的电能,此情况下待充电设备的总充电电流波动小,充电可靠性较高。本发明还公开了一种充电方法及系统,与上述充电装置具有相同的有益效果。
