Title:
電源システムおよびそれを搭載する車両、ならびに蓄電装置の制御方法
Document Type and Number:
Japanese Patent JP5556902
Kind Code:
B2
Abstract:
An electric power supply system (105) for supplying a load device (180) with driving electric power includes an electric power storage device (110) and an ECU (300). The electric power storage device (110) includes a CID configured to interrupt an electrical conduction path of the electric power storage device (110) in response to the electric power storage device (110) having an internal pressure exceeding a rated value. The controller (300) calculates a voltage variation length corresponding to an integral of an amount by which a voltage applied to the load device (180) varies in magnitude and a current variation length corresponding to an integral of an amount by which a current input/output to/from the electric power storage device (110) varies in magnitude for each sampling period for a predetermined period of time. Then, the ECU (300) determines whether or not the CID has been operated, based on the voltage variation length and the current variation length.
