-The converter should be always powered (as the BMS) to avoid dead locks.
+The converter should be always powered (as the BMS) to avoid dead locks. Therefore I like to use VBAT as power source.
-The power supply is based on a XL7015 Buck DC to DC Converter (0.8A 150KHz 80V) from {{https://www.xlsemi.com|XLSEMI}}. The 5V output voltage can be defined by two resistors (R1/R2). The CAN interface is implemented by well-known TJA1050 from {{https://www.nxp.com/docs/en/data-sheet/TJA1050.pdf|NXP}} and a standard RJ45 plug. The heart of the converter is a 38-pin ESP32-DEVKIT.
