Description

The Victron Energy VE.Bus BMS V2 is a new generation Battery Management System (BMS) designed to connect and protect one or more 12.8V & 25.6V Lithium Smart Batteries (LiFePO4 or LFP) in systems with Victron inverters or inverter/chargers with VE.Bus communication. It monitors and protects the batteries from over and under voltage in each individual cell and also against over and under temperatures. Quick and easy installation of the cabling, as the accesses are installed on the side.

Depending on the status of the battery(ies), the BMS will:

Generate a pre-alarm signal to warn of impending cell undervoltage.
Disable inversion in VE.Bus inverters or inverter/chargers via VE.Bus and switch off other loads via the load disconnect terminal in case of cell undervoltage.
Disable charging in VE.Bus inverters or inverter/chargers via VE.Bus and disable other chargers via the charge disconnect terminal in case of cell overvoltage, undertemperature or overtemperature.

It has additional properties such as:

Terminals for remote switching on and off.
Ability to disable VE.Direct and VE.Can solar chargers via a GX device.

Ability to control the VE.Bus inverter/charger from multiple devices such as the Digital Multi Control, the VE.Bus Smart Dongle and/or a GX device.
Auxiliary input and output terminals that allow a GX device to remain powered in the event of a system shutdown.
It protects every single cell of a Victron Lithium Battery Smart. For reliable and safe operation, a LiFePO₄ battery must be monitored and protected against overvoltage and undervoltage of each individual cell as well as overheating and undertemperature. The Victron lithium smart batteries include integrated cell voltage monitoring, cell voltage balancing and temperature monitoring. If the cell voltage or battery temperature is out of range, this is communicated to the BMS via two BMS cables with M8 circular connectors. In a multi-battery system, the BMS cables of each battery are connected in series (daisy chain), with the first and last BMS cables connected to the BMS.
