Document Type and Number:
Japanese Patent JP7176156
Kind Code:
B2
Abstract:
In a deterioration determination device for a storage battery system, a plurality of storage battery arrays, each of which is formed by connecting a plurality of storage batteries to each other in series, is connected to each other in parallel. The storage batteries are bipolar lead storage batteries. In the storage battery arrays connected to each other, the storage batteries positioned at one end portion of the storage battery arrays are connected to each other in parallel, and the storage batteries positioned in the middle part of the storage battery arrays are connected to each other in parallel. As a result, the storage battery system is divided into a plurality of storage battery array blocks. The deterioration determination device includes a current sensor that, at the time of stopping the charging or stopping the discharging of the storage batteries, measures the circulation current generated among the storage battery arrays in each of the storage battery array blocks; includes a measurement control unit that collects the value of the circulation current measured by the current sensor; and includes a storage battery state determining unit that, from the collected value of the circulation current, determines whether or not there is deterioration of the storage batteries in the storage battery array blocks.
