The present disclosure provides a method for fast charging an electric vehicle battery. A controller initiates a discharge pulse of a traction battery charging an auxiliary battery in response to a command for fast charging the traction battery, and initiates charging of the traction battery after the discharge pulse such that a voltage of the traction battery drops to a peak minimum during the discharge pulse, and continuously increasing immediately after the peak minimum without staying at a constant value to prevent the traction battery from ceasing between the discharge pulse and the charging of the traction battery.

    本公开提供“用于对电动车辆电池快速充电的方法”。控制器响应于用于对牵引电池快速充电的命令而发起所述牵引电池的对辅助电池充电的放电脉冲,并且在所述放电脉冲之后发起对所述牵引电池的充电,使得所述牵引电池的电压降低到所述放电脉冲期间的峰值最小值,并且紧接在所述峰值最小值之后连续地增加,而不停留在恒定值,以防止所述牵引电池在所述牵引电池的所述放电脉冲与所述充电之间停止工作。
