Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A battery management system, comprising:
at least one processor; and
a memory coupled to the at least one processor,
wherein the memory stores an instruction executable by the at least one processor, and when the instruction is executed by the at least one processor, the at least one processor is 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.
