  • Lithium-ion battery charging method for correcting and compensating voltage
    Patent number: 10707541
    Abstract: Lithium-ion battery charging method for correcting and compensating voltage, when it is charged to limited charge voltage of the battery, the battery stops charging, or start charging by constant-voltage charging and won't stop charging until the charging current is lower than 50%-99.99% of the current before constant-voltage charging; the limited charge voltage of the battery positive and negative electrodes is set as 3U0?US?USO; the battery would be rapidly charged and charged close to saturation, and have better cycle life than the battery charged by constant-current and constant-voltage charging method of the same charging rate; or with the same cycle frequency, the battery charged with the charging method of the present invention would have larger discharge capacity.
