A power control device configured for diagnosing an open circuit fault occurring in a power system of an automatic vehicle may include: a power control switch selectively connecting or disconnecting main power output from a first power source and auxiliary power output from a second power source; and a processor determining a likelihood of an open-circuit fault of the vehicle power supply based on the current flowing through the power control switch, and determining, when there is a likelihood of an open-circuit fault, whether the electric load can be driven with only the output power of the second power supply and determining an open-circuit position based on the output of the first power supply.
一种电力控制装置及其开路诊断方法,该电力控制装置被配置为用于诊断在自动车辆的电力系统中发生的开路故障,该电力控制装置可以包括:电力控制开关,选择性地连接或断开从第一电源输出的主电力和从第二电源输出的辅助电力;以及处理器,基于流过电力控制开关的电流确定车辆电源的开路故障的可能性,并且在存在开路故障的可能性时确定是否可以仅用第二电源的输出电力驱动电负载并且基于第一电源的输出确定开路位置。
