Victron Energy VE.Bus BMS
Victron Energy VE.Bus BMS
The VE.Bus BMS Part Number: BMS300200000 , protects each individual cell of a Victron lithium-iron-phosphate (LiFePO4 or LFP) battery.
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. Please see our LiFePO4 battery documentation for details.
The Victron VE.Bus 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).
Shut down or disconnect battery chargers in case of imminent cell overvoltage or over temperature.
Protects 12V, 24V and 48V systems
The operating voltage range of the BMS: 9 to 70V DC.
Communicates with all VE.Bus products
It 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 of imminent cell 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 of imminent cell over 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 of imminent cell over voltage or over temperature.
- Cell> 2,8V (blue): load disconnect output high.

Why lithium-iron-phosphate?
Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid: 2V/cell). A 12,8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.
Rugged
Lead-acid batteries will fail prematurely due to sulfation:
• If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).
• If it is left partially charged or worse, fully discharged (yacht or mobile home during wintertime).
LFP batteries do not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid. Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency (see below). LFP is therefore the chemistry of choice for very demanding applications.
Efficient
In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance. The round trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average leadacid battery is 80%. The round trip energy efficiency of a LFP battery is 92%. The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state). In contrast, a LFP battery will still achieve 90% efficiency under shallow discharge conditions.
Size and weight
Saves up to 70% in space Saves up to 70% in weight
Expensive?
LFP batteries are expensive when compared to lead-acid. But in demanding applications, the high initial cost will be more than compensated by longer service life, superior reliability and excellent efficiency.
Bluetooth
With Bluetooth cell voltages, temperature and alarm status can be monitored. Very useful to localize a (potential) problem, such as cell imbalance.
