Abstract

An effective management of battery electric vehicles and implementation of vehicle-to-grid programs requires being able to monitor battery parameters to assess the state of the battery. Current techniques have reached good accuracy, but usually require long measurement procedures and powerful hardware that makes them unfit for online battery monitoring. In this paper a one-shot measurement technique and the first experimental results for battery parameter estimation are presented: it is fast and can be implemented on a low-cost microcontroller to realize online battery monitoring.
