The invention discloses an electric quantity management method and system and a charging pile, and relates to the technical field of charging, the method is executed by the charging pile, and the method comprises the following steps: obtaining a power supply strategy, the power supply strategy is used for indicating a strategy for supplying power to the power receiving equipment or the energy storage battery based on the energy storage condition of the energy storage battery of the charging pile and the connection condition of the charging pile and the power receiving equipment; under the condition that the power supply strategy indicates to supply power to the power receiving equipment, supplying power to the power receiving equipment through at least one of first electric energy provided by a power supply connected with the charging pile and second electric energy provided by an energy storage battery; under the condition that the power supply strategy indicates that the energy storage battery is supplied with power, the energy storage battery is charged through first electric energy provided by the power source. The utilization rate of the charging pile can be ensured, peak load shifting is performed on the power grid, the load pressure of the power grid is relieved, and the problem of low charging efficiency caused by the fact that the charging pile is in a light-load working state for a long time is solved.

    本申请公开了一种电量管理方法、系统、充电桩,涉及充电技术领域,该方法由充电桩执行,包括如下步骤:获取供电策略,供电策略用于指示基于充电桩的储能电池的储能情况和充电桩与受电设备的连接情况向受电设备或者储能电池进行供电的策略;在供电策略指示向受电设备供电的情况下,通过充电桩连接的动力电源提供的第一电能和储能电池提供的第二电能中的至少一种向受电设备供电;在供电策略指示向储能电池供电的情况下,通过动力电源提供的第一电能向储能电池充电。能够保证充电桩的利用率,对电网进行削峰填谷,缓解电网负荷压力,并缓解充电桩长期处于轻载工作状态下所造成的充电效率低的问题。
