When the real-time full capacity is detected to be smaller than the primary power backup threshold value, the nonvolatile memory is informed to prepare a space with the size of x as a write cache space of an OS (system), and the volatile memory is informed to adjust the write cache space to b-x. And x is to ensure that the new standby power threshold corresponding to the write cache space of b-x is smaller than the current real-time full capacity.

Starting timing t until the value of x is changed again (namely, the real-time full capacity is fluctuated again) after the adjustment of the nonvolatile memory is finished, if x/a is between 30 and 80 percent and t is greater than s, issuing a system alarm to require the replacement of BBU, and recording a system prompt log under the other conditions.
In some embodiments, the method further comprises: and in response to the number of the batteries with faults at present being smaller than the number threshold and the real-time full capacity of the battery backup unit being larger than the primary power backup threshold, isolating the batteries with faults at present and recording a prompt log. When detecting that less than n cell faults and the real-time full capacity is greater than a standby power threshold, isolating the faulty cell immediately and recording a system prompt log.
In some embodiments, the method further comprises: and in response to the number of the batteries with the current faults being not less than the number threshold, alarming to replace the battery backup unit.
