Battery Management and Disconnect

Ensuring the safety, reliability, and longevity of the battery pack—the most critical and expensive component in an electric vehicle—is paramount.

Our portfolio of ASIL-compliant Power ICs and galvanically isolated current sensors provide accurate and reliable control needed to manager Power Distribution, Battery Disconnect and deliver highly-accurate information required for precise state-of-charge (SoC) and state-of-health (SoH) monitoring.

By providing reliable, real-time data, Allegro solutions protect the battery from thermal events, maximize its usable life, and give drivers an accurate, trustworthy understanding of their remaining range.
