    Abstract: A battery protection charging method and a charging system thereof are provided. The battery protection charging method includes obtaining an operation parameter of a battery. When a first protection condition is satisfied, a charging voltage of the battery is reduced to a first voltage. When a second protection condition is satisfied, the charging voltage of the battery is reduced to a second voltage. The second voltage is lower than the first voltage. The first (second) protection condition includes the cycle-life count is higher than a first (second) cycle-life threshold, the high voltage cumulative time is higher than a first (second) high voltage time threshold, and the high voltage-temperature cumulative time is higher than a first (second) high voltage-temperature time threshold.
