Abstract: A monitoring device for an energy storage device mounted on a vehicle includes: a memory; and a processor, wherein the memory is configured to store at least one of data on an estimated value of a parking-time discharge current, which the energy storage device discharges during parking, and data for calculating the estimated value of the parking-time discharge current. The processor is configured to perform first SOC estimation processing in which an SOC of the energy storage device is estimated by integrating estimated values of the parking-time discharge current based on the data stored in the memory when the vehicle is in a parking state.

Abstract: 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.

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: An electric storage device management system includes a voltage sensor, a memory, and a controller. The voltage sensor detects a voltage across an electric storage device having a correlation between an open circuit voltage (OCV) and a state of charge (SOC) including a slight change region and a sharp change region. The memory stores information on correlation between OCV and SOC in the sharp change region. The controller is configured to: determine an OCV based on a voltage detected by the voltage sensor; determine whether the defined OCV is within the sharp change region; determine an SOC corresponding to the defined OCV based on the stored information stored if the defined OCV is within the sharp change region; determine the determined SOC as an estimated SOC; and prohibit the determining of the SOC as an estimated SOC if the defined OCV is out of the sharp change region.
