Green Smart BMS: Intelligent Battery Management System

The project originated when the author purchased an electric motorcycle for his daughter and replaced its original lead-acid gel battery with a lithium battery pack. Due to the lack of smart, cheap and easy to configure lithium battery management systems on the market, the author decided to make one himself.

small engine control

This reference design board supports the NXP® MM912_P812 engine control IC, which combines an MCU (S12P) and an analog control chip (MC33812), and is suitable for motorcycles and other single/double-cylinder small engine control applications.

The analog control IC consists of three integrated low-side drivers, a pre-driver, a +5.0 V voltage pre-regulator, an MCU watchdog circuit, an ISO 9141 K-Line interface and a parallel interface for MCU communication.
