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 state estimation apparatus configured to estimate a state of an assembled battery including a plurality of energy storage devices. The energy storage devices each have a small-variation region where an open circuit voltage (OCV) variation amount relative to a residual capacity is smaller, and a variation region where the OCV variation amount relative to the residual capacity is greater than the OCV variation amount relative to the residual capacity in the small-variation region. The state of the assembled battery is estimated based on a varying position of the variation region relative to an actual capacity of the plurality of energy storage devices.
