VE.Net Battery Controller
No more guessing
Identifying exactly how much energy is left in a battery is not
easy. A voltmeter is useful but will only indicate that the battery is
at when it is too late. In order to keep an accurate record of what
is stored in a battery it is necessary to keep account of all the
factors that affect it and this is a complex matter. Once a reliable
reading of the state of charge of the battery is available however,
life starts to get an awful lot less complicated.
No more nasty surprises with batteries going at unexpectedly
and it becomes possible to manage batteries on fact rather than
guess work. It is amazing how much power you can have with a
little extra knowledge!
Accurate and reliable
The data used by the VE.Net Battery Controller is monitored with
an accuracy better than 0,5% and, employing Peukert’s formula,
account is taken of the reduction of effective capacity of the
battery when the discharge current increases. An optional
temperature sensor helps to further improve accuracy where
wide temperature variation is expected.
Standard information
- Battery voltage (V)
- Battery charge/discharge current (A)
- Consumed Ampere-hours (Ah)
- State of charge of the battery (%)
- Time to go (until the battery it at at the present rate of
discharge)
- Battery temperature
Start your generator
The VE.Net Battery Controller has a relay that you can use to
start your generator or to activate an external alarm for remote
monitoring. With the built in and adjustable hysteresis for State of
Charge (%) you can program when to close and open the
contacts at your desired levels.
Adjustable Alarms
The Battery Controller can generate alarms on:
- Low voltage
- High voltage
- State of charge
Intelligent communication to other VE.Net enabled devices
The data from the Battery monitor will be available to all devices
on the VE.Net network. The VE.Net Generator Module can use it
to start and stop the generator. VE.Net enabled Battery Chargers
can use it to optimize the charge currents to eliminate inuences
from a varying load.
Historic data
To enable you to interrogate;
- Deepest discharge (Ah)
- Depth of last discharge (Ah)
- Number of cycles
- Average discharge (Ah)
- Number of full discharges
- Cumulative Battery Amp Hours (Ah)
- Maximum Battery Volts (V)
- Minimum Battery Volts (V)
- Days since last full charge
Variable shunt parameters
The VE.Net Battery Controller can be used with any shunt as an
alternative to the standard 500A/50mv shunt included with the
package. In the menu you can setup the full current rating of the
shunt (10 - 50000A) and the according voltage in millivolts
(10 - 50 mV).
