BMV-702 Battery Monitor

<h2>Battery fuel gauge, time-to-go indicator, and much more</h2> <p>The 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.</p> <p>Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power consumption in Watts.</p> <p>The BMV-702 features an additional input which can be programmed to measure voltage (of a second battery), battery temperature or midpoint voltage (see below).</p> <h2>Bluetooth Smart</h2> <p>Use the Bluetooth Smart dongle to monitor your batteries on Apple or Android smartphones, tablets, macbooks and other devices.</p> <h2>Very easy to install</h2> <p>All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to the monitor with a standard RJ12 telephone cable. Included: RJ12 cable (10 m) and battery cable with fuse (2 m). No other components needed.</p> <p>Also included are a separate front bezel for a square or round display appearance, a securing ring for rear mounting and screws for front mounting.</p> <h2>Easy to program (with your smartphone!)</h2> <p>A quick install menu and a detailed setup menu with scrolling texts assist the user when going through the various settings.</p> <p>Alternatively, choose the quick and easy solution: download the smartphone app (Bluetooth Smart dongle needed)</p> <h2>Midpoint voltage monitoring (BMV-702 only)</h2> <p>Often used in industry to monitor large and expensive battery banks, this feature is now for the first time available at a low cost to monitor any battery bank.</p> <p>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, differences in temperature, internal leakage currents, capacities and more.</p> <p>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.</p> <h2>Standard features</h2> <p>- Battery voltage, current, power, ampere-hours consumed and state of charge</p> <p>- Remaining time at current rate of discharge</p> <p>- Programmable visual and audible alarm:</p> <p>- Programmable relay, to turn off non-critical loads or to run a generator when needed.</p> <p>- 500 A quick connect shunt and connection kit</p> <p>- Shunt selection capability up to 10 000 A.</p> <p>- VE.Direct communication port</p> <p>- Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health.</p> <p>- Wide input voltage range: 6,5 – 95 V</p> <p>- High current measurement resolution: 10 mA (0,01 A)</p> <p>- Low current consumption: 2,9 Ah per month (4 mA) @12 V and 2,2 Ah per month (3 mA) @ 24 V</p> <h2>BMV-702 additional features</h2> <p>Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding relay and alarm settings.</p> <h2>BMV-700H: 60 to 385 VDC voltage range</h2> <p>No prescaler needed. Note: suitable for systems with negative ground only (battery monitor is not isolated from the shunt).</p> <h2>Other battery monitoring options</h2> <p>- Lynx Shunt VE.Can</p> <h2>More about midpoint voltage</h2> <p>One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual, section 5.2, for more information.</p> <p>We recommend our Battery Balancer – BMS012201000 – to maximize service life of series-connected lead-acid batteries.</p> <h2></h2> <p></p>
