摘要：
A lithium-ion battery non-constant-voltage charging method for correcting and compensating a voltage. When the voltage of a battery in charging reaches a charging limit voltage, the charging process is stopped; the charging limit voltage between two electrodes of the battery is set to U=3Uo-Us-Uso, Uso being a standard stable voltage obtained after the battery is charged to Uo in a constant-current and constant-voltage manner and the voltage of the battery drops, Us being a stable voltage obtained after the battery is charged to Uo in a constant-current manner and the voltage of the battery drops, and Uo being a standard charging cut-off voltage; Uso is selected starting from the moment when the constant-current and constant-voltage charging for the battery is stopped, and timing is performed during the postponing; the battery is charged from a certain time period; when the open-circuit voltage drop of the battery is less than a certain numerical value within a certain time period and when the voltage of the
