The invention relates to a method for operating a switching device. A rechargeable energy storage system RESS (130) includes a plurality of battery packs (131, 132, 133) arranged in parallel and a switching device (115) including an associated contactor (141, 142, 143) of each battery pack configured to connect and disconnect the battery packs with respect to a traction voltage bus (135) by closing and opening, respectively, the traction voltage bus is connected to at least one load (110). The method comprises providing an opportunity window (S10) that does not allow implementation of a request to power the load by the battery pack and does not allow implementation of a request to charge the battery pack, in the opportunity window, preventing the contactors from opening such that equalization is achieved due to a current transfer between the battery packs (S30), measuring the current transfer between the battery packs (S20, S40), and blocking the contactor from opening (S30) and/or opening the contactor (S50) in response to the measured current transfer.

    本发明涉及一种用于操作开关装置的方法。可再充电能量储存系统RESS(130)包括多个并联布置的电池组(131、132、133)以及开关装置(115),该开关装置包括每个电池组的相关联的接触器(141、142、143),该接触器被配置成分别通过闭合和断开而将电池组相对于牵引电压总线(135)连接和断开,该牵引电压总线连接到至少一个负载(110)。该方法包括:提供不允许实施由电池组给负载供电的请求并且不允许实施对电池组充电的请求的机会窗口(S10),在机会窗口中,阻止接触器断开,从而由于电池组之间的电流转移而实现了均衡(S30),测量电池组之间的电流转移(S20、S40),并且响应于所测量的电流转移,阻止接触器断开(S30)和/或断开接触器(S50)。
