STORAGE BATTERY DEVICE

摘要

A voltage measurement unit (200) measures the voltage value between both ends of each of batteries (101-1) to (101-n). A control unit (300) determines whether or not the batteries (101-1) to (101-n) are defective based on the measured voltage values, outputs the series voltage of batteries (101-1) to (101-n) as the output voltage of a series body (100-1) if there is no battery, from among the batteries (101-1) to (101-n), that is determined to be defective, and outputs the boosted voltage from the voltage of the batteries (101-1) to (101-n) other than the battery that was determined to be defective as the output voltage of the series body (100-1).

主权项

1. A storage battery device including a plurality of storage batteries, wherein
a plurality of series bodies, each formed of the multiple storage batteries being connected in series, are connected in parallel, the series body comprises: a voltage measurement unit for measuring the voltage value between both ends of each of the multiple storage batteries, and, a control unit which determines whether or not the storage batteries are defective based on the voltage values measured by the voltage measurement unit and performs such control that if there is no storage battery that was determined to be defective, the series voltage of the multiple storage batteries is output as the output voltage of the series body whereas if there is a storage battery that was determined to be defective, the boosted voltage from the voltage of the batteries other than the defective battery is output as the output voltage.
