Charging/discharging control device and method for canceling memory effect in secondary battery |
摘要 |
A device and a method are provided in which memory effects can be cancelled by controlling charging and discharging of a secondary battery during driving of a vehicle. When a memory effect determinator determines that the discharging memory effect has occurred, based on at least one of the following determinations: whether a time of charging/discharging of a secondary battery has reached a predetermined time; whether a charging/discharging amount in the secondary battery has reached a predetermined amount; and whether a voltage per cell has reached a voltage V1 at a lower-limit state of charge in a range of capacity actually used, a discharging controller discharges the secondary battery until the voltage per cell reaches a voltage V3 that is higher than 1.0 V and is lower than the voltage V1 at the lower-limit state of charge.
