  "textContent": "A charging method and a charging apparatus are provided. The method includes the following. A battery is charged in a constant current stage until a voltage of the battery reaches a first voltage, where the first voltage is a charging cut-off voltage corresponding to the constant current stage. When the voltage of the battery reaches the first voltage, the battery is charged in a constant voltage stage by applying a second voltage to the battery, where the second voltage is lower than the first voltage. According to the above technical solution, a charging voltage applied in the constant voltage stage is lower than the charging cut-off voltage corresponding to the constant current stage, so that a low voltage can be applied for constant-voltage charging. On the other hand, by decreasing the charging voltage applied in the constant voltage stage, a charging time for constant-voltage charging can be shortened, which is beneficial to prolonging service life of the battery.",
