    Abstract: A switch failure diagnosis device for using in a current path between an electric device and an electric storage device includes plural switches, a switch terminal voltage detector, and a controller. The switches are connected parallel to each other in the current path. The switch terminal voltage detector outputs a switch terminal voltage detection signal. The controller is configured to: select the switches at different time in sequence and input an open instruction signal to each switch at the time when the switch is selected; and determine, based on the switch terminal voltage detection signal output while the open instruction signal is given, that at least one of the switches has a failure if the detected voltage is in a failure determination range.

    Abstract: A management device manages a secondary battery which includes a positive electrode having an active material with a characteristic where a potential flat portion exists in a relationship between a capacity and a potential. The management device includes a management unit which detects an occurrence of temporary degradation of the secondary battery when an SOC correlation associated value which is associated with an SOC of the secondary battery is acquired and the SOC which corresponds to the acquired SOC correlation associated value is equal to or less than a preset prescribed SOC or when a state value relating to a voltage of the secondary battery is acquired and a magnitude relationship between the acquired state value relating to the voltage of the secondary battery and a preset threshold value satisfies a predetermined condition.

    Abstract: A switch failure detection device includes a switch, a rectifier, a switch voltage detection circuit, and a controller. The switch is connected in a path in which a charging current to and a discharging current flow. The rectifier passes a discharging current by bypassing the switch when the switch is turned off. The detection circuit detects a voltage between an input and an output of the switch. The controller is configured to: determine whether the electric storage device is in a discharging state; send an off-command signal to the switch if the electric storage device is in the discharging state; receive the voltage; determine an input-output voltage of the switch based on the voltage; determine whether the input-output voltage is lower than a first reference voltage; and determine the switch has a turn-off problem if the input-output voltage is lower than the first reference voltage.
