摘要： An energy storage apparatus 50 includes an energy storage cell 62, a current interruption device 53 that interrupts a current I to the energy storage cell 62 and a control unit 121. The control unit 121 interrupts a current by opening the current interruption device 53 in a case where abnormality of the energy storage apparatus 50 is detected together with a vehicle crash, and resumes the supply of electricity to a vehicle, which has been crashed, by closing the current interruption device 53 in a case where the abnormality is no longer detected.

摘要： In a generation method for an energy storage device model, in order to simulate a transient actual voltage behavior when an actual current flows in an actual energy storage device for a predetermined period, a parameter in an energy storage device model is adjusted such that a transient model voltage behavior, which is a behavior when a model current equivalent to the actual current flows in the energy storage device model for a predetermined period, approaches the actual voltage behavior. In the generation method for an energy storage device model, in the adjustment, the parameter is changed so as to simulate a state transition of the energy storage device model accompanied by the flow of the model current.
