摘要： Several embodiments perform battery backup unit (BBU) degradation testing. For example, a BBU testing system can be coupled to or part of a BBU. The BBU testing system can discharge the BBU by engaging a variable load to the BBU. The BBU testing system can monitor a discharge energy consumption over time as the BBU discharges until the discharge energy consumption reaches a specified amount of energy. The BBU testing system can determine a discharge time for the discharge energy consumption to reach the specified amount of energy. The BBU testing system can then compute a degradation state of the BBU based on the discharge time.

摘要： A method of testing a battery pack, wherein a load is connected to a charger and the battery pack, and receives power supply from either the external charger or the battery pack. When the external power line is normally supplied to the load through the charger, the battery pack is purposely enabled to start its discharge and to supply power to the load. When the output voltage of the battery pack drops below a threshold level or the discharging time exceeds a preset limit, the charger re-supplies its output voltage to the load and to charge the battery pack. By the purposeful charge/discharge operations, characteristic data of the battery pack are collected and recorded for estimation of the battery pack capacity and the remaining service life.

摘要： According to one embodiment, a storage battery evaluation device includes a charging/discharging controller and a deterioration evaluator. The charging/discharging controller acquires a charging/discharging power command value, performs control to charge and discharge an energy storage device according to the charging/discharging power command value, sets a dead zone in which the charging and discharging is not performed when an absolute value of the charging/discharging power command value is equal to or smaller than a threshold, and performs control to stop the charging and discharging when the charging/discharging command value enters the dead zone. The deterioration evaluator measures a response characteristic of a voltage of the energy storage device at a time when the charging and discharging is stopped from a state in which the energy storage device is charged and discharged and evaluates a deterioration state of the energy storage device on a basis of the response characteristic.
