Victron Energy BMV-702 BAM010702000R Battery monitoring

Battery "Fuel Gauge", remaining indicator and much more
The remaining battery capacity depends on the used ampere-hours, the discharge current, temperature, and the age of the battery. There are complex software algorithms required to all these
Variables must be taken into account. Apart from the basic display options such as voltage, current and spent ampere-hours shows the bmv-700 series also the charge state, the remaining time and the power consumption in watts. The bmv-702 has an additional input, which to measure the voltage (a second battery), temperature or center point voltage (see below) can be programd.

Easy to set up
All electrical connections are connected to the PCB connector at the current shunt. The shunt is with the monitor via a standard RJ12 telephone cable. Included in the scope of delivery: RJ12 cable (10 m) and the battery cable with fuse (2m); no further components are required. In addition, a separate front plate for a square or round display; a safety ring for a rear mounting and screws for a front-sided mounting is included.

Simple programming
A quick installation menu, and a detailed setup menu with scrolling supports the user if he makes the different settings. Please note the manual for more details.

Monitoring of the center point voltage (only BMV-702)
This function is used frequently in the industry, the size and cost-intensive battery banks to monitor, is now available for the first time at a lower price, so that any battery bank
Can be supervised. A battery bank consists of a train in a row downstream cells. The center point voltage is the voltage after half of the string. In the ideal case, the center point voltage exactly half of the total voltage. In practice, however, will lead to deviations. These are by numerous factors, such as from a different charging status with new batteries or cells, different temperatures, internal leakage currents, capacities and still many more. Size or increasing deviations to the center point voltage indicate an improper battery maintenance or faulty battery or cell. Corrective measures as a result of a center point voltage alarm can prevent serious damage to an expensive battery. Please also pay attention to the manual for more information.
