The invention discloses a charging method, a charging device and a charging pile, and belongs to the field of charging piles. The charging method comprises the steps of determining first closing time information of a relay arranged in a target two-phase line based on a first zero-crossing moment of a line voltage between the target two-phase line in a three-phase line and an input current corresponding to the target two-phase line; controlling relays arranged in the target two-phase line to be closed at the same time based on the first closing time information; and when the relay in the target two-phase line is in a closed state, charging a bus capacitor connected between the target two-phase line based on the commercial power. According to the charging method provided by the invention, the relay can be ensured to be completely closed at the voltage zero crossing point under any condition, so that the current impact is controlled within a reasonable range, the device loss is reduced, and the service life and the use stability of equipment are effectively improved.

    本申请公开了一种充电方法、充电装置和充电桩,属于充电桩领域。所述充电方法,包括:基于三相线中目标二相线之间的线电压的第一过零时刻和目标二相线对应的输入电流,确定设置于目标二相线内的继电器的第一闭合时间信息;基于第一闭合时间信息控制设置于目标二相线内的继电器同时闭合;在目标二相线内的继电器闭合状态下,基于市电对接入目标二相线之间的母线电容进行充电。本申请的充电方法,能够保证在任何情况下均能使继电器在电压过零点完全闭合,从而将电流的冲击控制在合理范围,减缓了器件损耗,有效提高设备使用寿命和使用稳定性。
