The invention discloses a charging inversion switching method, which comprises the following steps of: receiving a grid-connected inversion instruction of demand response, and turning off all chargers; judging whether each bin position participates in grid-connected inversion or not; according to the determined battery cabins participating in inversion, a series connection instruction is sent to the single cabins participating in inversion in sequence; after all single cabins participating in inversion are connected in series, an inversion instruction is sent to the main control board; closing the relay, connecting the battery pack to the inverter in series, and waiting for the inverter to start up; and sending a query state instruction to the inverter through the serial port, waiting for normal standby of the inverter, and sending a startup instruction to the inverter. The safe charging and battery replacing functions of the battery replacing cabinet are achieved, meanwhile, the electric power demand response of an electric power department can be responded, and the construction of a novel electric power system is increased.
本发明公开了一种充电逆变切换方法,包括以下步骤:收到需求响应的并网逆变指令,关断所有充电器;判断各仓位是否参加并网逆变;根据确定参加逆变的电池仓,依次向参加逆变的单仓发送串联指令;等待所有参加逆变的单仓串联完成,向主控制板发送逆变指令;闭合继电器,将电池组串接入逆变器,等待逆变器开机;通过串口向逆变器发送查询状态指令,等待逆变器正常待机,向逆变器发送开机指令。实现了换电柜的安全充电以及换电功能,同时还可响应电力部门的电力需求响应,为新型电力系统建设添砖加瓦。
