电池监视装置以及电池监视装置的诊断方法
摘要：
本发明提供一种电池监视装置以及电池监视装置的诊断方法，其能够诊断电池状态检测电路是否正常动作动，提高可靠性的电池监视装置，电池监视装置具备根据串联连接的多个电池单体(BC1～BC4)的各单体电压，检测电池单体的电池状态的电池状态检测电路(270、272、276、278、400、RPU、R1～R4、RPD、MUX1～MUX5)、根据多个电池单体的各单体电压(BC1～BC4)监视电池单体的状态的控制电路(30)，控制电路(30)向电池状态检测电路(270、272、276、278、400、RPU、R1～R4、RPD、MUX1～MUX5)输入模拟电压信息，诊断该电池状态检测电路是否正常动作。
摘要（英）：

The invention provides a battery monitoring device and diagnosis method thereof, which can diagnosis whether the battery state detection circuit can actuate normally or not and improve the reliability of the battery monitoring device, the battery monitoring device has each monomer voltage of a plurality of battery monomers (BC1-BC4) which are connected in series; the battery state detection circuits (270, 272, 276, 278, 400, RPU, R1-R4, RPD, MUX1-MUX5) for detecting the battery states of the battery monomers; a control circuit (30) for monitoring the states of the battery monomers according to each monomer voltage (BC1-BC4) of a plurality of battery monomers, wherein, the control circuit (30) can input analog voltage information to the battery state detection circuits (270, 272, 276, 278, 400, RPU, R1-R4, RPD, MUX1-MUX5) to diagnosis whether the battery state detection circuits can actuate normally or not.
