Battery equipment discharge blancing method

Abstract

The invention provides a battery equipment discharge balancing method, wherein a battery module of the battery equipment includes a plurality of battery blocks connected in parallel, and each battery block includes a plurality of battery cells connected in series. During the discharging process, the voltage of each battery cell is measured to generate a plurality of battery cell voltages. When any one of battery cell voltages reaches a cut-off discharge voltage, it is determined that the battery module is fully discharged. Thereafter, a minimum battery cell voltage in each battery block is obtained respectively to generate a plurality of cut-off battery cell voltages. The discharge ratio of each battery block in the next discharge process is adjusted according to the cut-off battery cell voltages respectively, so as to increase the discharge capacity and service life of the battery module.
