Abstract
A battery data-logging arrangement for use with an electric vehicle is disclosed. The arrangement includes a first analog-to-digital converter (A2D) that converts a battery voltage signal to battery voltage data. A second A2D converts a battery current signal to battery current data. A clock generates time data. A computer memory is associated with a central processing unit (CPU) that correlates and stores the battery voltage data, the battery current data, and the time data in the memory.
