Battery Monitoring IC’s

Nuvoton offers a lineup of high performance battery monitoring ICs including automotive qualified, stackable, and built-in current sensor.Applications include electric and hybrid electric vehicles, energy storage systems and e-bikes.

Battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs) are becoming more and more popular to achieve carbon neutrality worldwide.
Automakers are encouraged to ensure safety against hazardous events such as lithium-ion batteries catching fire and emitting fumes. The cruising range per charge of BEVs must be extended equivalent to a single fueling of internal combustion engine vehicle. The high safety and long cruising range required for battery systems are supported by Nuvton battery monitoring ICs with various safety functions and enables highly accuratevoltage measurement.

Wide range of battery cell abnormalities and BMS failures can be detect by Nuvoton BM-ICs that include diagnosis and safety functions.High precision voltage measurement error help to extend the battery duration. Measuring up to 25 connected battery cells in series and BMS can be configured with smaller number of components for a high-voltage battery system with many battery cells connected in series, contributing to the miniaturization of the battery module.
