Your Batteries "Fuel Gauge", "Time-to-Go" indicator, and much more
Remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account. Next to the basic display options, such as voltage, current and ampere-hours consumed, the Victron BMV-702 also displays state of charge, time to go, and power consumption in Watts.
The BMV-702 features an additional input which can be programmed to measure the voltage of a second battery, battery temperature and midpoint voltage. Midpoint voltage monitoring, a unique BMV-702 feature, is often used in industry to monitor large and expensive battery banks, is now for the first time made available at a low cost, to monitor any battery bank. A battery bank consists of a string of series connected cells. The midpoint voltage is the voltage halfway along the string. Ideally, the midpoint voltage would be exactly half of the total voltage.
In practice, however, deviations will be seen, and that depends on many factors such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacities and much more. Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or cell. Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery. (Consult the BMV manual for more information.)
A quick install menu and a detailed setup menu with scrolling texts on the BMV-702 assist the owner when going through the various settings. Alternatively, choose the fast and easy solution: download the smartphone app and use an optional Bluetooth Smart dongle to monitor your batteries on Apple or Android smartphones, tablets, macbooks and other devices.
