The invention relates to a charging management method and a charging management system for an energy storage power supply. When the external power supply interface is a vehicle-mounted charging interface, the output current is limited according to the first current or the first current range, and when the external power supply interface is a photovoltaic panel charging interface, the magnitude of the on-load voltage is continuously judged; and if the load voltage is in the second voltage range, limiting the output current according to the third current or the third current range, and starting the maximum power tracking of the photovoltaic panel. According to the charging management method, the type of the external power supply is accurately judged, a corresponding current limiting strategy is adopted according to the type, when the external power supply is a vehicle charging port, a preset current value or range is limited and locked so as to ensure the safety and stability of the charging process, and when the external power supply is a photovoltaic panel, current limiting is performed according to the working voltage range of the photovoltaic panel so as to ensure the safety and stability of the charging process. And the photovoltaic panel can output power at the maximum efficiency.
本发明涉及一种储能电源的充电管理方法及充电管理系统。当外部电源接口是车载充电接口,根据第一电流或第一电流范围限定输出电流,当外部电源接口是光伏板充电接口,持续判断带载电压的大小;若带载电压处于第二电压范围时,根据第三电流或第三电流范围限定输出电流,并启动光伏板的最大功率追踪。本发明通过充电管理方法准确地判断外部电源的类型,并根据类型采取相应的限流策略,外部电源为车充口时,限定锁死预设的电流数值或范围,以确保充电过程的安全和稳定性,外部电源为光伏板时,根据光伏板的工作电压范围进行限流,保证光伏板能够以最大效率输出功率。
