The invention relates to low charge acceptance mitigation. A vehicle may include a battery and a controller programmed to set a bus voltage threshold such that during a next charging event a voltage of the battery achieves a desulfation value. The controller may set the bus voltage threshold in response to charge acceptance of the battery falling below a predetermined sulfation value. The controller may be programmed to lower the threshold such that the voltage of the battery falls below the desulfation value. The controller may lower the threshold in response to the charge acceptance exceeding the predetermined sulfation value during a next event. 本发明涉及低充电接受度的缓解。种车辆包括电池和控制器，所述控制器被配置为：设置总线电压阈值，使得在下次充电事件期间电池的电压达到脱硫值。所述控制器可响应于电池的充电接受度下降到预定硫化值以下而设置所述总线电压阈值。所述控制器可被配置为：降低所述总线电压阈值，使得电池的电压下降到脱硫值以下。所述控制器可响应于在所述下次充电事件期间所述充电接受度超过预定硫化值而降低所述总线电压阈值。
