Standard requests to BMS in the form of a request for basic data, secondary voltage and names in the ASCII line are parsed in the file (from the manufacturer).
I will not analyze them.
Further, the deals with undocumented features in the form of reading / writing EEPROM.
Hello
I purchased an BMS controller (JBD-SP30S005 V1.3). Recently, I incorrectly connected the charger (without grounding) when the BMS was connected to the computer's USB. As a result, the computer does not see the USB (the safety resistor on the board is blown out). Can I replace the microcontroller AtMega328p and download the firmware?
