蓄電池システム
Document Type and Number:
Japanese Patent JP6596818
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a storage battery system capable of measuring a voltage of each storage battery cell at low cost under condition that each storage battery cell is in a substantially identical charge/discharge state even when a charge/discharge current sequentially changes.SOLUTION: In a storage battery system, a host controller 110 comprises a current measuring unit 111 which measures currents flowing in a plurality of storage battery cells 102; a voltage-measuring-timing determination unit 113 which determines voltage measuring timing for the storage battery cells 102 on the basis of the currents measured by the current measuring unit 111; and a voltage-measuring-instruction output unit 114 which outputs a voltage measuring instruction for the storage battery cells 102 to each monitor node 104 on the basis of a determination result of the voltage measuring timing by the voltage-measuring-timing determination unit 113. Each monitor node 104 measures a voltage of each storage battery cell 102 in response to the voltage measuring instruction from the voltage-measuring-instruction output unit 114.SELECTED DRAWING: Figure 1
