The intelligent charging of pond group.
As shown in Figure 1, the circuit module that the present invention is provided with is made up of charger, battery pack two parts；The charger portion
Dividing includes control module, programmable power supply module, communication module, reverse-filling module, communication interface and charging inlet；The battery pack
Part includes BMS and battery；The control module is connected with programmable power supply module, communication module respectively, and programmable power supply module connects
Take over control and pour in down a chimney module, reverse-filling module connection charging inlet；The communication module is connected with communication interface, and communication interface passes through
RS485 communicates with BMS, while charger connects BMS by charging inlet being charged to battery pack.
The charger is divided into two kinds of mode of operations of automatic mode and manual mode, under automatic mode, it is necessary to detect and fill
The delivery outlet of electrical equipment has battery to access can just be exported；Under manual mode, charger can force output.
The charger has first detected whether that battery is accessed, and detects after battery is accessed and just exports, and prevents battery to charging
There is the phenomenon poured in down a chimney in device.
Specific implementation step is as follows：First Li-ion batteries piles are connected with charger, output VOUT+, VOUT- of charger
OUT+, OUT- of battery pack are connected respectively, and the RS485 communication interfaces of charger are connected with the RS485 communication interfaces of battery pack；So
Afterwards, charger is opened, automatic mode is defaulted as after charger start, start to read BMS information, recognize the capacity of battery, automatically
Maximum output current value is set, starts automatic charging.
The present invention is applied to voltage 48V, capacity 3Ah-30Ah Li-ion batteries piles.
The present invention is that the Li-ion batteries piles for solving different capabilities under identical electrical voltage system are charged with same charger and ask
Topic, charger is communicated by RS485 with the BMS of battery pack, according to communication protocol, the battery capacity for accessing is recognized, according to difference
Battery capacity determine output maximum current value, realize compatible various capacity batteries；Prevent battery from pouring in down a chimney when accessing existing
As, relay is concatenated with the output end of charger by charger interface, when battery is accessed, relay is off-state,
After first detection battery is accessed, then charger output be closed again relay, it is therefore prevented that battery is accessed may be to the straight of charger
Electric capacity between stream output end charges, that is, described pours in down a chimney phenomenon.
It is " C6 29 of 7E 0A 01 00 00 30 00 ", BMS responses letter that charger sends Query Information in communication protocol
Breath " the B0 00....... of 7E 0A 01 56 00 ", represent access charger is 30Ah battery packs, and is underfill state,
Charger will be started to charge up with maximum 0.8C (24A) electric current, and charge mode is the electric current of exporting change according to monomer voltage,
Constant pressure output is finally at, until battery is full of.
