Non-constant-voltage charging method for lithium ion battery capable of correcting and compensating voltage

The invention discloses a non-constant-voltage charging method for a lithium ion battery capable of correcting and compensating voltage. According to the charging method, when the voltage of the battery in charging reaches a charging limiting voltage, the charging process is stopped; the charging limiting voltage between two electrodes of a battery is set to U=3Uo-Us-Uso, wherein Uso refers to a standard steady voltage of battery voltage drop after the battery is charged to Uo in a constant-current and constant-voltage manner; Us refers to a steady voltage of the battery voltage drop after the battery is charged to Uo in a constant-current manner; Uo refers to a standard charge cut-off voltage; the selection of Uso is from the moment when the constant-current and constant-voltage charging for the battery is stopped; the battery is charged from a certain time frame; when the open-circuit voltage drop of the battery is less than a certain numerical value within a certain time frame, and when the voltage of the battery is steady, a voltage corresponding to the first time point within the time frame is selected as the standard steady voltage Uso of the battery. The charging method is high in charging speed, and almost saturated electric quantity can be charged for the battery; by adoption of the charging method, the charged battery has a longer cycling life when the battery is discharged by a standard method or a user's method; or under the same number of cycles, the discharged capacity of the battery is higher when the battery is charged by the charging method provided by the invention.
