das ist dass einzige was ich habe:
For instructions on heating cables,
the green 5PIN cable of the heating cable needs to be linked to the heating pad,
and the rest of the black and red cables are linked to the smart charger
(after the smart charger links the BMS,
it detects the temperature of the battery through the BMS,
which automatically monitors the charging status of the battery)
Heat Function interface
Description of heating function:
Battery temperature is below low temperature charge protection, turn off charging, turn on heating.
Battery temperature is higher than low temperature charge recovery temperature, turn on charging, turn off heating.
Cryogenic charge protection is a parameter that can be set within APP
The heating power depends on the battery voltage and the resistance value of the heating film.
Battery voltage U.
Heating resistance R.
Power equals U*U/R
Heating current I=U/R;
The maximum I (current) of the board design is 3A.
MAX heating power 200W(100W OF B2A8S20P).
Green this line, connect the negative pole of the heating film, and connect the positive pole of the heating film to the battery.
Only in the case of non-charger heating, it is necessary to connect the black and red wires, and only the charger can be connected for charging and heating.
Smart Charger is a charger that can flexibly adjust the charging voltage,
Under normal circumstances, customers will choose to use the battery to discharge electricity and heat itself, and do not need to connect these two wires.
