Victron VE.Bus BMS
Victron VE.Bus BMS
Features:
- Protects Each Cell in LiFePO or LFP Batteries
- For 12,24 and 48V Systems
- Includes AC Detector
- LED Indicators
- VE.Bus Communication
Each individual cell of a LiFePO4 battery must be protected against over voltage, under voltage and over temperature. Victron LiFePO4 batteries have integrated Balancing, Temperature and Voltage control (acronym: BTV) and connect to the VE.Bus BMS with two M8 circular connector cord sets. The BTVs of several batteries can be daisy-chained. Up to five batteries can be paralleled and up to four batteries can be series connected (BTVs are simply daisy-chained) so that a 48V battery bank of up to 1500Ah can be assembled. Please see our LiFePO4 battery documentation for details.
The BMS will:
- shut down or disconnect loads in case of imminent cell under voltage,
- reduce charge current in case of imminent cell overvoltage or over temperature (VE.Bus products only, see below), and
- shut down or disconnect battery chargers in case of imminent cell overvoltage or over-temperature.
More Product Features:
Protects 12V, 24V and 48V Systems:
The operating voltage range of the BMS is: 9 to 70V DC.
Communicates with all VE.Bus products
The VE.Bus BMS connects to a MultiPlus, Quattro or Phoenix inverter with a standard RJ45 UTP cable. Other products, without VE.Bus can be controlled as shown below:
Load Disconnect:
The Load Disconnect output is normally high and becomes free-floating in case the cell goes under voltage. Maximum current: 2A.
The Load Disconnect output can be used to control:
- the remote on/off of a load, and/or
- the remote on/off of an electronic load switch (Battery Protect)
Charge Disconnect:
The Charge Disconnect output is normally high and becomes free-floating in case the cell goes under voltage or over temperature. Maximum current: 10mA.
The Charge Disconnect output can be used to control:
- the remote on/off of a charger and/or
- a Cyrix-Li-Charge relay and/or
- a Cyrix-Li-ct Battery Combiner
LED Indicators:
- Enabled (blue): VE.Bus products are enabled.
- Cell>4V or temperature (red): charge disconnect output low because the cell goes under voltage or over temperature.
- Cell>2.8V (blue): load disconnect output high.
Applications:
Marine
RV's
Caravans
Off-Grid Systems
Tiny Houses
Cabins
