Wiring sequence
When assembling the wiring, correctly weld the row wire to the cell, connect the B- of PCM to the total negative electrode of the cell, and insert the row wire into the pin holder of PCM.
(note: different connection modes with different string Numbers, and different connection modes with the same port)
The BMS Can use for 3S~ 24S : If you purchased 14S,then 14S BMS can use for 3S~14S
If you purchased 16S, then 16S BMS can use for 3S~16S It can use for less series.
How to let it use for less series :
Note:
The corresponding battery pack should be formed first
2. The change from high string number to low string number has nothing to do with the style
3. The number of protection panel string can only be changed to low number, not high number. The minimum support is 3 battery packs
4. The above is the schematic diagram of the wiring connection between the high-number protection board and the low-number battery pack. Please follow the wiring diagram prepared at the time of delivery for the input and output
5. Not every protection board supports changing the number of strings. The integration scheme and software board do not support changing the number of strings.
6. Wiring method: starting from BC0, BC0 is connected to the total negative terminal of the battery, the second row of BC1 is connected to the first positive terminal, and the third row of BC2 is connected to the second positive terminal BC3
The fourth row is connected to the third battery positive pole, and so on, and the empty row is connected to the total positive pole of the battery.
