Midpoint voltage monitoring (BMV-702 only)
This feature which 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, dependent 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. Please consult the BMV manual for more information.
