摘要： In a self-diagnostic processing performed by a CPU, whether a vehicle is in an idle stop state is determined based on obtained vehicle operation information and engine operation information in order to perform abnormality detection processing. When an engine has stopped in a vehicle equipped with an idle stop function, electric power is supplied to electrical components of the vehicle, which means a battery supplies currents to the electrical components. Consequently, if a current measurement result obtained by measuring a current while the vehicle is stationary and an ignition is ON indicates that the measurement value is equal to or below a prescribed current value, the CPU determines that an abnormality has occurred in a measuring system.

摘要： 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.

摘要： A monitoring apparatus for an energy storage device provided at a movable body and electrically connected to a load of the movable body via a switch, includes a monitoring unit supplied with power from the energy storage device. The monitoring unit executes monitoring operation of bringing the switch from a closed state into an opened state under a condition that the energy storage device has voltage not more than a discharge voltage threshold, and bringing the switch from the opened state into the closed state under a condition that the switch is in the opened state and the energy storage device satisfies a predetermined discharge recovery condition, and decreases power consumption by extending an interval of the monitoring operation when the load is under suspension while the switch is in the opened state, in comparison to a case where the load is in operation.

摘要： 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.
