Low Maintenance Batteries in Combination with Battery Supervision System

Abstract

Lead-acid batteries in modern design and with correct choice of alloy have a topping up interval of several years. However, this does not mean that the battery can be left without service during the corresponding time. The battery needs supervision of cell voltages, densities, levels and temperatures much more often than water filling, which means that the long topping up intervals of modern batteries cannot be fully utilized. By combination of a low maintenance battery and a battery supervision system for cell voltages, current, battery temperature and electrolyte level, a minimum of maintenance and a maximum of availability is obtainable. Furthermore a more optimized service life of the battery will be possible by use of the battery supervision system. In this paper a more detailed description of such a combined system of battery and supervision will be outlined.
