The invention provides an interaction method of a charging pile, the charging pile comprises an EMS controller and a plurality of power modules, the interaction method is applied to the EMS controller, the interaction method comprises the following steps: receiving the maximum available power sent by each power module, the maximum available power being determined by the corresponding power module according to a target parameter and through a table look-up method, wherein the target parameter comprises at least one of self voltage, self current or target temperature; and performing power control on the charging pile at least according to the maximum available power of each power module. As the EMS controller only needs to receive the maximum available power of each power module, the number of times of interaction between the EMS controller and each power module can be reduced, and the communication load rate between the EMS controller and the power modules is ensured to be relatively low; therefore, the problems of high communication load rate and low communication speed between the EMS controller and the power module in the prior art are solved.

    本申请提供了一种充电桩的交互方法,充电桩包括一个EMS控制器和多个功率模块,交互方法应用在EMS控制器中,该交互方法包括:接收各功率模块发送的最大可用功率,最大可用功率为对应的功率模块根据目标参数以及通过查表的方法确定的,其中,目标参数包括以下至少之一:自身电压、自身电流或者目标温度;至少根据各功率模块的最大可用功率,对充电桩进行功率控制。由于EMS控制器只需接收各个功率模块的最大可用功率即可,这样可以减少EMS控制器与各个功率模块的交互次数,保证了EMS控制器与功率模块之间的通信负载率较低,从而解决了现有技术中EMS控制器与功率模块之间的通信负载率较高以及通信速度较慢的问题。
