Internal resistance estimation apparatus for power storage device, degradation determination apparatus for power storage device, power supply system, and internal resistance estimation method for power storage device |
摘要 |
A converter control unit responds to a command from a start determining unit to control a converter such that a ripple current is generated at a secondary battery. A storage unit stores a map defining a correlative relationship between the temperature and current of the secondary battery and internal resistance. An estimating unit estimates a value of internal resistance of the secondary battery based on each detection value of the temperature and current, and the map stored in the storage unit. |
