Victron Energy VE.Bus BMS V2

The Victron - VE.Bus BMS 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.

Description

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 BMS will: 

• Generate a pre-alarm signal to alert of an imminent cell under voltage condition. 
• Disable inverting in VE.Bus inverters or inverter/chargers via VE.Bus, and disable other loads via the 'Load Disconnect' terminal in the event of a cell under voltage condition. 
• Disable charging in VE.Bus inverters or inverter/chargers via VE.Bus and disable other chargers via the 'Charge Disconnect' terminal in the event of a cell overvoltage, under temperature or over temperature condition. 

The “next generation” VE.Bus BMS V2 has additional features such as: 

• Remote on/off terminals. 
• Ability to disable VE.Direct and VE.Can solar chargers via a GX device. 
• Allowing control of the VE.Bus inverter/charger from multiple devices, like the Digital Multi Control, the VE.Bus Smart dongle and/or a GX device. 
• Auxiliary power input and output terminals that allow a GX device to remain powered in the event of a system shutdown.
