Victron Energy Battery Management System VE.Bus BMS Charger

Features:

- Protects each individual cell of a Victron lithium iron phosphate (LiFePO4or LFP)battery: Each individual cell of a LiFe PO4 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 fivebatteries 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 over voltage 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: 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 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.
