Battery Monitor BMV-702

Features

Bluetooth Inside: With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth being implemented in most other Victron Energy products, wireless communication between products will simplify system installation and enhance performance.

VictronConnect App: Use a smartphone or other Bluetooth enabled device to:

• Customize settings
• Monitor all important data on single screen
• View historical data
• Update the software when new features become available

Easy to Install: 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. 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.

Midpoint Voltage Monitoring: 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. We recommend a Battery Balancer to maximize service life if you’re utilizing series-connected lead-acid batteries.

Low Current Draw from Battery: Current consumption of 0.7 Ah per month (1 mA) @12 V and 0.6 Ah per month (0.8 mA) @ 24 V. Especially Li-ion batteries have virtually no capacity left when discharged until low voltage shutdown. After shutdown due to low cell voltage, the capacity reserve of a Li-ion battery is approximately 1Ah per 100 Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10 mA for example may damage a 200 Ah battery if the system is left in discharged state
during more than 8 days.

Bi-Stable Alarm Relay: Prevents increased current draw in case of an alarm.

Other Features:

• Battery voltage, current, power, ampere-hours consumed and state of charge
• Remaining time at the current rate of discharge
• Programmable visual and audible alarm
• Programmable relay, to turn off non critical loads or to run a generator when needed
• 500 Amp quick connect shunt and connection kit
• Shunt selection capability up to 10,000 Amps
• VE.Direct communication port
• Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health
• Wide input voltage range: 6.5 – 70 V
• High current measurement resolution: 10 mA (0.01 A)
• Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings
