Battery Management System

The battery management system (BMS) solution is based on MS51 to improve the battery's utilization rate, prevent battery overcharge and overdischarge, and accurately control each battery cell. Based on Nuvoton's solution, it is convenient for customers to do the second development and enter the market faster.
