The BMS protects the battery from damage, extends the life of the battery with intelligent charging and discharging algorithms, predicts how much battery life is left, and maintains the battery in an operational condition. Lithium-ion battery cells present significant challenges, demanding a sophisticated electronic control system. Plus, there is a significant risk of injury from fires and explosions. A BMS therefore requires cutting-edge silicon to meet all performance, safety and cost metrics.

In general, the three main BMS challenges that every designer strives to improve are maximizing driving range, improving cost and enhancing safety.

Solving one of these challenges may adversely impact the other. In this white paper, we’ll discuss several emerging trends to address all three challenges.
