The BMV-700 is a high-precision battery monitor.
The essential function of a battery monitor is to calculate the ampere-hours consumed and the state of charge of the battery.
The consumption in ampere-hours is calculated by integrating the flow of current entering or leaving the battery.
Battery fuel gauge, remaining autonomy indicator, and much more
The remaining capacity of the battery depends on the ampere-hours consumed, the discharge current, the temperature, and the age of the battery.
To account for all these variables, complex software algorithms are required. In addition to basic display options, such as voltage, current, and ampere-hours consumed, the BMV-700 series also displays the state of charge, remaining autonomy, and power consumption.
The BMV-702 features an additional input that can be programmed to measure the voltage (of a second battery), temperature, or median voltage (see below).
Very simple installation
All electrical connections are made via quick connection on the shunt's printed circuit board (PCB).
The shunt is connected to the monitor with a standard RJ12 telephone cable.
Included: RJ12 cable (10 m) and battery cable with fuse (2 m).
No other components are necessary. The other supplied parts are a dial for a square or round display, a mounting ring for rear mounting, and the screws needed for front mounting.
Easy to program
A quick installation menu and a detailed configuration menu with scrolling texts assist the user during the various settings.
Please refer to the manual for further details.
New: median voltage control (BMV-702 only)
Often used in the industrial sector to control expensive and large battery banks, this function is now available for the first time at a reduced cost to monitor any battery bank.
A battery bank consists of a series of cells connected in series.
The median voltage is the voltage halfway along this series. Ideally, the median voltage should be exactly half of the total voltage.
In practice, however, there will be discrepancies, depending on many factors such as a different state of charge for new batteries or cells, temperature differences, internal leakage currents, capacities, etc.
A significant or increasing discrepancy in the median voltage indicates poor battery maintenance, or a failing battery and cells.
If a median voltage alarm occurs, corrective action can prevent serious damage to an expensive battery.
Please refer to the BMV manual for further information.
