Battery Management System AS has developed management systems since 1990. The systems were based on a patented method of collecting data from all single cells over a single wire communication line. This gave an easy installation and very few wires on the battery top. The first systems were for submarine applications; later the systems were adapted for 48 V telecom backup. Systems for 400 V UPS systems were also delivered. Later, the systems have been upgraded for use in another two other submarine classes. In 2000-2005 BMS-AS also developed systems for remote monitoring of telecom battery plants, using the mobile network. Over a period of several years, BMS-AS monitored and reported back to telecom company status from 30-40 large battery plants in Denmark and Sweden. Development, production and sales of measurement systems ceased in 2006.
