BMV 712 Smart status monitor

Product detailed description

The BMV-712 Smart Tracker is a high accuracy dual independent battery status monitoring model with integrated Bluetooth technology.

Why monitor battery operating conditions? To make it last longer! Detailed battery monitoring allows us to correct any operational deficiencies with quick remediation to promote long battery life.
Suitable for all types of lead-acid batteries including AGM and gel batteries. Easy adjustment of battery capacity (factory setting to 200 Ah). Voltage autodetection 12, 24, 36, 48, 60, 120, 144 and 288 V. Regular automatic calibration of the instrument for reliable indication of measured data (can also be done manually). The BMV 700H version is designed for systems with high operating voltages (70 - 350 V DC), the BMV702 version is designed for monitoring two batteries or monitoring temperature or battery xxx. The tracker is also suitable for Li-on batteries.


Product parameters:

- current voltage (V) of the battery
- the current current (A) going into (positive values - charging) or out (negative values - discharging) of the battery
- the current power (W) going into (positive values - charging) or out (negative values - discharging) of the battery (voltage and current multiplied)
- the total amount of energy drawn from the battery to power the appliances in ampere hours (Ah)
- current battery charge percentage
- predicted (sophisticatedly calculated) time in hours to 50% battery discharge for a given power consumption

- maximum capacity deviation ±0.1 Ah for 0-100 Ah capacity battery
- maximum capacity deviation ±1 Ah for a 100 - 9999 Ah capacity battery
- maximum deviation in the reading of the state of charge ±0.1%
- maximum deviation in the estimation of the remaining time ±1 hour (in the range of 1-240 hours)
- maximum deviation in power reading ±1 W in the range from - 100 W to 1 kW
- for total battery capacity 20 - 9999 Ah

The tracker stores selected historical data and the limit values reached:
- deepest battery discharge achieved
- the rate of the last battery discharge
- number of battery discharge/charge cycles
- average battery discharge value
- number of full battery discharges
- maximum battery voltage reached
- minimum battery voltage reached
- number of days since the last full battery charge

The BMV-700 includes:
- custom tracker with backlit digital display and controls
- plastic tracker cap with dimensions 69 x 69 mm
- 500A/50mV lateral designed for 500A maximum pride (install on negative cable)
- 10 meter long RJ12 UTP communication and power cable (connecting the tracker to the side tracker)
- 2 meter long installation cable with fuse to connect to the positive cable.

The tracker performs sophisticated tracking of the supplied and drawn energy together, taking into account adjustable values of the Peukert exponent (the greater the energy draw, the lower the amount of available energy in the batteries, and vice versa) and the battery to estimate the current amount of energy Ah) and the battery charge rate (in percentage). To correctly display the amount of available energy in the battery, it is necessary that all energy going in and out of the battery is coming in laterally.
The tracker itself can be integrated into the wall without close access from behind (covered screws).
For larger currents like 500 A, a spare side designed for currents of 1000 and 2000 A can be added. A lateral up to a maximum current of 9 999 A with a voltage range of 1 - 100 mV (both adjustable) can be used on the tracer.
The monitor has a switched relay. This is activated/deactivated based on the measured battery charge rate. It is factory set to switch on when the battery charge level is below 50% and off when the battery charge level reaches 90%. These values can be changed in the settings. Also, the switching logic can be reversed, i.e. standard is off, non-standard is off. The relay can be used for switching on/off devices such as external alarm, power station etc.
The tracker can be connected to other devices. Possibility to connect the trackers with a large colour display Color Control GX. To connect the BMV700 to the Color control GX display, either the VE.Direct cable or the VE.Direct-USB communication interface must be purchased.
Saved settings and measured historical and limit data remain saved and when power is interrupted to the tracker. Visual and audible alarms on over or under voltage, charged or discharged battery. Possibility to switch an additional power source such as a generator via relay under defined conditions.
