Zusammenfassung:The invention provides a high-side driver diagnostic method and a battery system. The battery system includes a battery pack, a relay connected to the battery pack, a high side driver (HSD) configured to apply a relay driving voltage to a high side of the relay, and a battery management system (BMS) configured to diagnose the HSD based on a voltage measured from the relay or a first end of the HSD. 本公开提供一种高侧驱动器诊断方法和电池系统。所述电池系统包括电池组、连接到电池组的继电器、被配置为向继电器的高侧施加继电器驱动电压的高侧驱动器(HSD)以及被配置为基于从继电器或HSD的第一端测量的电压来诊断HSD的电池管理系统(BMS)。
