Hi! Great project! I have experience in developing BMS from the scratch - schemes, PCBs, firmware. Also, I worked a lot with all stuff, connected to electric vehicles and bicycles - powerful batteries, motor controllers, high-level control logic, CAN interconnection. I have almost 10 years of experience programming STM32, working with BLE (I can make a custom FW for SOCs), SPI and CAN. Actually I did one BMS for myself - I have a powerful electric bicycle. BMS has 72V 100A with stm32 onboard and CAN connection. Looking forward to speaking more about the project!
