The invention discloses a charging system power limiting method, a controller and a charging system, and relates to the technical field of new energy. The charging system comprises at least one power module. The method comprises the following steps: acquiring input limiting power and current input power of the charging system; issuing limited power data to each power module based on the input limited power and the current input power so as to feed back and adjust the current input power of the charging system; executing the updating process for multiple times until a preset condition is met; wherein in each updating process, the limited power data is re-determined based on the current input power and the input limited power of the charging system after adjustment, and the current input power of the charging system is re-fed back and adjusted based on the re-determined limited power data; the preset condition comprises that a power difference value between the current input power and the input limiting power of the charging system is in a preset range. Therefore, the accuracy and precision of limiting the input power by the charging system are improved.

    本申请公开了一种充电系统功率限制方法、控制器及充电系统,涉及新能源技术领域。充电系统包括至少一个功率模块,该方法包括:获取充电系统的输入限制功率和当前输入功率;基于输入限制功率和当前输入功率向各功率模块下发限功率数据以反馈调节充电系统的当前输入功率;多次执行更新过程,直至满足预设条件;其中,每次更新过程中,基于调节后充电系统的当前输入功率和输入限制功率重新确定限功率数据,并基于重新确定的限功率数据再次反馈调节充电系统的当前输入功率;预设条件包括充电系统的当前输入功率与输入限制功率的功率差值在预设范围内。由此,以提高充电系统限制输入功率的准确度和精度。
