The invention provides vehicle battery leak detection. A circuit may be selectively attached to one of a positive terminal and a negative terminal of a traction battery cell via a transistor. The circuit has a current sensor disposed in series with an inductor. A controller operates the transistor such that current from the one of the positive terminal and the negative terminal is reversed within the circuit and disables charging and discharging of the traction battery cell when an inductor charge rate is less than a predetermined charge value.
本公开提供了“车辆电池泄漏检测”。一种电路可经由晶体管选择性地附接到牵引电池单元的正极端子和负极端子中的一个。所述电路具有与电感器串联设置的电流传感器。控制器操作所述晶体管使得来自所述正极端子和所述负极端子中的所述一个的电流在所述电路内反向,并且当电感器充电速率小于预定充电值时,禁止所述牵引电池单元的充电和放电。
