fig. 2 shows another schematic flow chart of a method for detecting and activating a storage battery in place according to a second embodiment of the present invention, and for convenience of description, only the parts related to the second embodiment of the present invention are shown, which is detailed as follows:
s201: powering on equipment and initializing data; after the parallel power supply equipment is powered on, data such as PFC control, charging control, DC/DC control, mains supply voltage sampling, battery voltage sampling, output voltage sampling and output current sampling are initialized, and the equipment performs self-checking.
S202: charging low-voltage output, and activating and discharging the storage battery; and controlling the charging function circuit to output the set low voltage.
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, the output time is 10 seconds, and most of the power supply charging output can not be set to 0V output because the power supply charging output supplies power to an auxiliary power supply or other circuits inside the power supply equipment besides charging the storage battery. When the low voltage is output, if the storage battery is in the state of being charged, the storage battery is not charged in 10 seconds in one minute, and meanwhile, the storage battery can supply power to functional circuits such as an auxiliary power supply and the like, and the low current discharges, so that the storage battery activation effect is achieved, and the floating charge time of the storage battery is reduced.
S203: whether the sampling voltage is equal to the set output low voltage or not; if the sampling voltage is equal to the output set low voltage and the charging current is less than the set value, that is, the storage battery on-site condition is not met, executing step S204; if not, the sampling voltage is not equal to the output set low voltage or the charging current is equal to the set current, then step S208 is executed.
The charging sampling voltage is the battery sampling voltage, the charging output interface and the battery input interface belong to the same interface, and the charging control circuit samples the charging voltage and feeds the charging voltage back to the CPU, so that the stability of the charging voltage is controlled conveniently.
S204: charging the high voltage output; and controlling the charging function circuit to output the set high voltage.
Taking a 48V rated voltage battery pack 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 set output high voltage or not; if the sampling voltage is equal to the output set high voltage, that is, the storage battery on-site condition is not satisfied, executing step S206; if not, the step S208 is executed, i.e. the sampling voltage is not equal to the output set high voltage.
S106: judging whether the charging current is smaller than a set current or not; if yes, judging that the storage battery is not in place, and executing step S207; if not, that is, the charging current is equal to the set current, it can be determined that the battery is in place, and step S208 is executed.
S207: the battery is not in place.
S208: the storage battery is in place; through the judgment of S203 and S205, if the charging voltage sampling value is different from the set value and the charging current changes, the storage battery can be judged to be in place.
S209: starting normal charging, and starting or continuing timing charging; and starting a charging circuit, setting charging voltage and charging current according to the configured storage battery information, and starting or continuing charging timing at the same time.
For example, the double-pole 12V 25AH 4 batteries are connected in series, and generally set with the uniform charging voltage of 56.5V, the floating charging voltage of 54.5V and the charging current of 0.1C, namely 2.5A. The charging timing period is generally set to be 1 minute, namely 50 seconds are charged in 1 minute, the storage battery is not charged in 10 seconds, and meanwhile, the storage battery has low current discharge, so that the activation effect of the storage battery is achieved, the floating charge time of the storage battery is reduced, and the service life of the storage battery is prolonged.
S210: whether the timing time meets a set rated value or not; if yes, go to step S202; if not, step S209 is executed, i.e., the timer is continuously counted.
