Battery block monitoring Battery block monitoring Mounting/connecting the battery block sensors After installing the battery terminal jumpers, con- nect the battery block sensors. Pay attention to cor- rect polarity. Connect the black minus cable with bat- tery minus and the red plus cable with battery plus.
Connect the black minus cable with bat- tery minus and the red plus cable with battery plus. As the battery block temperature measurement is carried out via the negative lead of the battery block sensor, the battery block sensor housing does not need to have a heat conducting connection with the battery block housing.
Figure 1. A Simplified Diagram of the Building Blocks of a Battery Management System A battery management system can be comprised of many functional blocks including: cutoff FETs, a fuel gauge monitor, cell voltage monitor, cell voltage balance, real time clock (RTC), temperature monitors and a state machine.
In addition, the battery block monitoring sys- tem enables automation of the annual operating life test, as manual cyclic measurement of the individual battery block voltage values is no longer required. A potential-free chan- geover contact reports the operating status to a higher-level building management system if required.
One way to maintain multiple batteries is to use a hard disconnect switch. This switch allows you to disconnect the secondary batteries from the main battery when they are not in use. This can help prevent the main battery from becoming stranded if the secondary battery is drained.
The Smart BatteryProtect must be installed in a well-ventilated area and preferably close (max 50 cm) to the battery (but, due to possible corrosive gasses not above the battery!). Choose the correct cable size and length to match the load.
