Victron Energy BMS300200000 VE.Bus BMS

Victron Energy VE.Bus BMS: Each Individual Cell Of A Lifepo4 Battery Must Be Protected Against Voltage, 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 an 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.
