Claim 4:
5. A battery charging controller, comprising one or more processors, wherein the processors work individually or jointly, and the processors are configured to:
perform a charging process on a battery; and
monitor an electrical parameter of the battery during the charging process;, wherein the charging process consists of the following steps:
when the electrical parameter of the battery reaches a first threshold, suspending charging of the battery and discharging the battery by applying a first negative pulse for a first duration of t1;
continuing to charge the battery after discharging the battery for the first duration of t1;
when the electrical parameter of the battery reaches a second threshold, suspending charging of the battery and discharging the battery by applying a second negative pulse for a second duration of t2; and
continuing to charge the battery after discharging the battery for the second duration of t2;, wherein the first duration t1 is greater than or equal to 3 seconds and less than 13 seconds, the second duration t2 is greater than 3 seconds and less than or equal to 13 seconds, and t1 is less than t2; and, wherein the electrical parameter is state of charge (SOC), and the first threshold is lower than the second threshold.
