The invention discloses over-current protection based on slope detection. A control circuit for use in a solid state battery disconnect and protection system is disclosed wherein the control circuit includes a high voltage switch coupled between a battery and a DC link capacitor of an electric vehicle wherein the electric vehicle is powered by the battery; and a control block. The control block may be operable to monitor a rate of change of current and a value of current across a connection of the high voltage switch, determine whether the rate of change of current exceeds a first predetermined threshold, and determine whether the value of current exceeds a second predetermined threshold, and determining the presence of an overcurrent fault if the first predetermined threshold value or the second predetermined threshold value is exceeded.

    本发明公开了基于斜率检测的过电流保护。公开了一种用于在固态电池断开和保护系统中使用的控制电路,其中控制电路包括高压开关,该高压开关耦合在电动车辆的电池和DC链路电容器之间,其中电动车辆由电池供电;和控制块。控制块可以可操作以监测到高压开关的连接件上的电流的变化速率和电流的值,确定电流的变化速率是否超过第一预定阈值,并且确定电流的值是否超过第二预定阈值,以及在第一预定阈值或第二预定阈值被超过的情况下确定存在过电流故障。
