Solution for Electrochemical Impedance Spectroscopy (EIS) in Battery Management System
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
A battery management system chipset, with Electrochemical Impedance Spectroscopy (EIS) enabled, brings a classical laboratory technology to the in-vehicle use. This solution consists of three gateway devices, to synchronize devices and transfer data; the cell module controller to measure voltage and voltage based component response; and the junction box controller to measure the current and current based excitation frequency component. NXP’s new devices provide the benefits of EIS in chip packages that can be directly exchanged on the cell module and battery junction box (BJB) control units.
