NXP introduces a BMS chipset integrating EIS technology, significantly improving battery health monitoring capabilities.

NXP Semiconductors recently announced its first battery management system (BMS) chipset based on hardware-level synchronization mechanism using electrochemical impedance spectroscopy (EIS) technology, enabling precise monitoring of all cells within a high-voltage battery pack. This innovative technology brings laboratory-level diagnostic capabilities to automotive applications, significantly improving battery health monitoring. The chipset consists of three BMS units: the BMA7418 cell sensor, the BMA6402 communication gateway, and the BMA8420 battery junction box controller, enabling real-time, high-frequency monitoring without the need for additional components or redesign.
