Document Type and Number:
WIPO Patent Application WO/2017/086400
Kind Code:
A1
Abstract:
A storage battery system of an embodiment of the present invention comprises: a power storage device that is connected in parallel with a lead storage battery installed in a vehicle equipped with a power generation device, and that is capable of storing power from the power generation device; and a control unit that sets a control SOC range so that a voltage value corresponding to a lower limit value of the control SOC range that is managed during normal usage in a storage battery device becomes an open circuit voltage value during discharge termination of the lead storage battery, and that changeably sets the control SOC range on the basis of an internal resistance value that was calculated or estimated for the lead storage battery and the storage battery device. Due to this configuration, in a vehicle equipped with an idling stop system, the characteristics of a lead storage battery can be utilized, the life of the lead storage battery can be extended, and regenerative power can be effectively utilized.
