Taking a 48V rated voltage battery pack as an example, the low voltage can be set to 40V, the current is set to 0.5A, and the output time is 10 seconds, and since most of the power supply charging output is used for charging the storage battery and supplying power to an auxiliary power supply or other circuits in the power supply equipment, the power supply cannot be set to 0V output. When the low-voltage output is carried out, if the storage battery is in the state, the storage battery is not charged for 10 seconds in one minute, meanwhile, the storage battery can supply power to functional circuits such as an auxiliary power supply and the like, and small current is discharged, so that the activation effect of the storage battery is achieved, and the floating charge time of the storage battery is shortened.

The charging sampling voltage is battery sampling voltage, the charging output interface and the battery input interface belong to the same, and the charging control circuit samples the charging voltage and feeds back the charging voltage to the CPU, so that the charging voltage is convenient to control to be stable.
S204: charging high voltage output; and controlling the charging function circuit to output the set high voltage.
Taking a 48V rated voltage battery as an example, the high voltage may be set to 57V, the current may be set to 0.5A, and the output time may be set to 2 seconds.
S205: whether the sampling voltage is equal to the high voltage of the set output or not; if the sampling voltage is equal to the output set high voltage, that is, the battery in-place condition is not satisfied, step S206 is executed; if not, the sampling voltage is not equal to the output set high voltage, step S208 is executed.
S106: judging whether the charging current is smaller than the set current or not; if yes, it may be determined that the battery is not in place, and step S207 is performed; if not, that is, if the charging current is equal to the set current, it can be determined that the battery is in place, and step S208 is performed.
S207: the battery is not in place.
S208: the storage battery is in place; the battery can be judged to be in place by judging in S203 and S205 that the charging voltage sampling value and the set value are different and that the charging current is changed.
S209: starting normal charging, and starting or continuing to time charging; and starting a charging circuit, setting charging voltage and charging current according to the configured storage battery information, and simultaneously starting or continuing charging timing.
For example, the double-deck 12V 25AH 4 storage battery is connected in series, and the charging voltage is generally 56.5V, the floating charging voltage is 54.5V, and the charging current is 0.1C, namely 2.5A. The charging timing period is generally set to be 1 minute, namely 50 seconds are required for charging in 1 minute, and 10 seconds are required for not charging the storage battery, and meanwhile, the storage battery is discharged with small current, so that the activation effect of the storage battery is achieved, the floating charge time of the storage battery is shortened, and the service life of the storage battery is prolonged.
S210: whether the timing time meets the set rated value or not; if yes, go to step S202; if not, step S209 is performed, i.e., the timer is continued.
