Title:
TEMPERATURE CONTROL APPARATUS FOR ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/099138
Kind Code:
A1
Abstract:
In a power storage system including a secondary battery (1) and a capacitor (2), a bidirectional DC-DC converter is set in mode for charging the secondary battery (1) with electricity when a first state of charge (SOC) of the secondary battery (1) is larger than a minimum value of the first SOC, and a second SOC of the capacitor (2) is smaller than a maximum value of the second SOC, and the bidirectional DC-DC converter is set in mode for discharging electricity from the secondary battery (1) when the first SOC is smaller than a maximum value of the first SOC, and the second SOC is larger than a minimum value of the second SOC. On the basis of an internal resistance of the secondary battery (1), the second SOC, a voltage of a direct current link, and a bidirectional DC-DC converter error with respect to a current on the direct current link side, which are obtained when a load is not connected to the direct current link, a conduction ratio (D) of the bidirectional DC-DC converter is calculated and control is performed, thereby controlling a temperature by means of a change of the internal resistance.
