The Battery Viewer uses a sophisticated algorithm and battery management software to monitor the ongoing battery values (voltage, current, charge balance, and temperature). In states where there is energy activity (charging or discharging), the system is in it wake mode with full CPU processing and communications. Its processing and its communication with the display are state-based, meaning it will go into sleep mode when their is no energy activity, or into low-energy current comparator mode when activity is low (<150mA). The IBS collects the data at a 1kHz sample rate, then pre-processes the data before delivering it to the Battery Viewer for higher level processing and display. The IBS resides on the battery post and continually communicates to the Battery Viewer over a small network cable via LIN-bus (an automotive network standard). The IBS technology is the same technology that is used in more than 20 million vehicles around the world that employ the fuel-saving and pollution-reducing Start-Stop technology The IBS itself is a sophisticated and robust device using an on-board ASIC micro-processor chip, a current-measuring shunt, a temperature sensor, and a LIN-bus network interface. The Battery Viewer uses Intelligent Battery Sensors (IBS), which are smart devices which reside on the battery terminal of each battery that is being monitored. They either require manual re-set, or re-set automatically using an occasional zero-out reset routine. Typical battery monitors have tiny screens, read out in an indecipherable code of abbreviations and symbols, and don't compensate for load balance, internal resistance or temperature. They are not adaptive devices, they don't model battery behavior, and they get more and more inaccurate the more you use them. They are basically counters which are tallying amps and hours. Amp-hour counters are simply current shunts coupled with a clock and a counter.
