The invention discloses battery shut-off mechanization for direct current fast charging. A battery system includes: a battery pack configured to be selectively connected to an output terminal and a DCFC socket of the battery system; the first contactor is connected between the DCFC socket and a first terminal of the battery pack; and a first SSR (Simple Sequence Repeat) connected in series with the first contactor between the DCFC socket and the first terminal of the battery pack. And a first SSR having an open state in which current from the DCFC socket to the battery pack is interrupted and a closed state in which current flows from the DCFC socket to the battery pack, the first SSR configured to transition from the closed state to the open state prior to the first contactor, and current flows from the DCFC socket to the battery pack only when both the first contactor and the first SSR are in the closed state.

    本发明公开了用于直流快速充电的电池切断机械化。一种电池系统包括:电池组,所述电池组配置为选择性地连接到所述电池系统的输出端子和DCFC插座;第一接触器,所述第一接触器连接在所述DCFC插座与所述电池组的第一端子之间;以及第一SSR,所述第一SSR与在所述DCFC插座与所述电池组的所述第一端子之间的所述第一接触器串联连接。所述第一SSR具有从所述DCFC插座到所述电池组的电流中断的断开状态以及电流从所述DCFC插座流动到所述电池组的闭合状态,所述第一SSR配置为在所述第一接触器之前从所述闭合状态转变到所述断开状态,并且电流仅在所述第一接触器和所述第一SSR两者处于所述闭合状态下时从所述DCFC插座流动到所述电池组。
