A simple and intuitive display shows the service battery voltage, charge/discharge current, state of charge, and time to charge/discharge. Nasa Clipper BM-2 Baterry Monitor also warns the user when the charge level is too low so that load can be shed or charging commenced to protect the battery. A resettable Amp Hour counter is provided for checking the efficiency of the charging system or keeping a track of power consumption and a second input lets the user monitor the voltage of the starter batter. The simple display format does not mean the internal software is unsophisticated. In fact two separate algorithms are used. One based on integrating amp hours over the charge and discharge cycle, the second based on an adaptive internal mathematical battery model.
A unique feature of the Nasa Clipper BM-2 Battery Monitor is its ability to use information from both algorithms, during the charge/discharge cycles, to continually update its performance. This means that, unlike many other systems that rely solely on amp hour integration, the Nasa BM-2 Battery Monitor never needs to be re-synchronised with the battery. The algorithm includes Peukert’s equation to ensure accuracy over a wide range of load currents.
The Nasa Clipper BM-2 Battery Monitor does all this whist consuming a meagre one and a half milliamps. Nasa Clipper BM-2 is a true battery monitor, easy to install and excellent value for money.
