Method for controlling battery charge and discharge

摘要

The present invention provides a method for controlling battery charging and discharging in which a battery is charged and discharged such that a SOC (state of charge) value of the battery is increased/decreased to a predetermined range when the SOC value of the battery is in a predetermined range; and a range of the SOC values in which charging and discharging processes are performed sequentially varies and a range of the SOC values after the charging and discharging processes also sequentially varies.
