Abstract
A mobile x-ray unit operates from a rechargeable battery in a number of different modes which draw current from the battery. Remaining battery capacity is calculated by integrating the current drawn from the battery in each of its operating modes, and periodically subtracting this value from a value indicative of remaining capacity. The result is displayed to provide an accurate indication of remaining battery capacity.
