BMV-712 Smart Battery Monitor

<h2>Integrated Bluetooth</h2> <p>With its integrated Bluetooth device, the BMV Smart is ready for the Internet of Things era. Thanks to the implementation of Bluetooth function in most Victron Energy products, wireless communication between products will simplify system installation and improve efficiency.</p> <h2>Download the Victron Bluetooth application</h2> <p>Use a Smartphone or other device with a Bluetooth connection to</p> <p>- customize your settings,</p> <p>- monitor all crucial data on a single screen,</p> <p>- view historical data,</p> <p>- and to update the software when new functions are available.</p> <h2>Very simple installation</h2> <p>All electrical connections are made by quick connection on the shunt's printed circuit board (PCB). The shunt is connected to the controller with a standard RJ12 telephone cable. Included: RJ12 cable (10 m) and battery cable with fuse (2 m). No other components are required.</p> <p>Other parts supplied are a display with a rectangular screen, a mounting ring for rear mounting, and the necessary screws for front mounting.</p> <h2>Midpoint voltage monitoring</h2> <p>One bad cell or one bad battery can destroy a large and expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see section 5.2 of the BMV manual for further information.</p> <p>We recommend our Battery Balancer – BMS012201000 – to optimize the service life of series-connected lead-acid batteries.</p> <h2>Very low current draw from the battery</h2> <p>Current consumption: 0.7 Ah per month (1 mA) @12 V and 0.6 Ah per month (0.8 mA) @ 24 V. Lithium-ion batteries in particular have almost no power left when discharged until shutdown due to low voltage.</p> <p>After a shutdown due to low cell voltage, the power reserve of a lithium-ion battery is approximately 1 Ah per 100 Ah of battery capacity. The battery will be damaged if the remaining power reserve is extracted from the battery. For example, a residual current of 10 mA can damage a 200 Ah battery if the system is left discharged for more than 8 days.</p> <h2>Bistable alarm relay</h2> <p>It prevents an increase in current draw in case of an alarm.</p> <h2>Other functions</h2> <p>- Battery voltage, current, power, ampere-hours consumed and state of charge</p> <p>- Remaining autonomy based on current consumption</p> <p>- Programmable visual and audible alarm:</p> <p>- Programmable relay to turn off non-critical loads, or to start a generator if necessary.</p> <p>- A 500 A quick-connect shunt and connection kit</p> <p>- Shunt capability up to 10,000 A.</p> <p>- VE.Direct communication port</p> <p>- Storage of numerous historical events that can be used to evaluate usage patterns and battery health.</p> <p>- Wide supply voltage range: 6.5 Ț"70 V</p> <p>- High current measurement resolution: 10 mA (0.01 A)</p> <p>- An additional input to measure voltage (of a second battery), temperature or midpoint voltage, and setting of corresponding relays and alarms.</p> <h2>Technical details:</h2> <p></p> <table> <tbody><tr><td>Battery controller</td> <td>BMV-712 Smart</td> </tr><tr><td>Supply voltage range</td> <td>6.5 - 70 VDC</td> </tr><tr><td>Current draw, backlight off</td> <td> </tr><tr><td>Input voltage range, auxiliary battery</td> <td>6.5 - 70 VDC</td> </tr><tr><td>Battery capacity (Ah)</td> <td>1 - 9999 Ah</td> </tr><tr><td>Operating temperature range</td> <td>-40 +50 ºC (-40 - 120 ºF)</td> </tr><tr><td>Measures voltage of a second battery,<br>or temperature, or midpoint</td> <td>Yes</td> </tr><tr><td>Temperature measurement range</td> <td>-20 +50 ºC</td> </tr><tr><td>VE.Direct communication port</td> <td>Yes</td> </tr><tr><td>Bistable relay</td> <td>60 V / 1 A normally open (function can be<br>reversed)</td> </tr><tr><td>RESOLUTION AND ACCURACY (with a 500 A shunt)</td> </tr><tr><td>Current</td> <td>± 0.01 A</td> </tr><tr><td>Voltage</td> <td>± 0.01 V</td> </tr><tr><td>Ampere-hours</td> <td>± 0.1 Ah</td> </tr><tr><td>State of charge (0 – 100%).</td> <td>± 0.1 %</td> </tr><tr><td>Time to go (Remaining autonomy)</td> <td>± 1 min</td> </tr><tr><td>Temperature (0 – 50 °C or 30 – 120 °F)</td> <td>± 1 °C/°F</td> </tr><tr><td>Current measurement accuracy</td> <td>± 0.4 %</td> </tr><tr><td>Voltage measurement accuracy</td> <td>± 0.3 %</td> </tr><tr><td>INSTALLATION and DIMENSIONS</td> </tr><tr><td>Installation</td> <td>Flush mounting</td> </tr><tr><td>Front</td> <td>63mm diameter</td> </tr><tr><td>Front bezel</td> <td>69 x 69mm (2.7 x 2.7 inches)</td> </tr><tr><td>Body diameter and depth</td> <td>52 mm (2.0 inches) and 31 mm (1.2 inches)</td> </tr><tr><td>Protection category</td> <td>IP55 (not designed for outdoor use)</td> </tr><tr><td>STANDARDS</td> </tr><tr><td>Safety</td> <td>EN 60335-1</td> </tr><tr><td>Emission/Immunity</td> <td>EN 55014-1 / EN 55014-2</td> </tr><tr><td>Automotive</td> <td>ECE R10-4 / EN 50498</td> </tr><tr><td>ACCESSORIES</td> </tr><tr><td>Shunt (supplied)</td> <td>500 A / 50 mV</td> </tr><tr><td>Cables (supplied)</td> <td>10 meters of UTP cable with RJ12 connectors and<br>supply wire with fuse for "+" connection</td> </tr><tr><td>Temperature sensor</td> <td>Optional (ASS000100000)</td> </tr></tbody></table><p></p> <p></p>
