The invention provides a current adjusting method and device and charging equipment, and relates to the technical field of power control, and the method comprises the steps: obtaining the load current of a target phase; under the condition that the load current of the target phase is greater than the preset phase current, determining a target down-regulation current of the target phase according to the preset phase current and the load current; and adjusting the working current of each charging device according to the target down-regulation current and the device down-regulation current of the target phase. According to the technical scheme provided by the invention, when the load current of any phase is too high, the load current of the phase can be reduced in time, so that overload protection can be realized in time, and the reliability of overload protection is improved.

    本申请提供一种电流调节方法、装置和充电设备,涉及电力控制技术领域,其中,该方法包括获取目标相的负荷电流;在目标相的负荷电流大于预设相电流的情况下,根据预设相电流和负荷电流确定目标相的目标下调电流;根据目标下调电流与目标相的设备可下调电流,调整各充电设备的工作电流。本申请提供的技术方案能够在任意相的负荷电流偏高时,及时地降低该相的负荷电流,从而就可以及时地实现过载保护,提高过载保护的可靠性。
