VE.Bus BMS V2

is an advanced battery management system designed specifically for Victron Energy Smart lithium battery systems. Designed to work with inverters and chargers. Victron, VE.Bus BMS V2 provides comprehensive protection for LiFePO4 lithium batteries (12.8V or 25.6V) by monitoring key parameters such as voltage and temperature. Thanks to this technology, batteries are protected against dangerous overvoltages, too low voltage and extreme temperature conditions..
The system's primary function is to continuously monitor the condition of the battery cells. When a low voltage is detected in any of the cells, the VE.Bus BMS V2 generates a pre-alarm signal, allowing the user to react before more serious damage occurs. Furthermore, in case of critical voltage values, the system automatically stops the operation of inverters and disconnects other energy consumers, minimizing the risk of further damage. Battery protection is a key element, as improper use can significantly shorten their lifespan.
Another advantage VE.Bus BMS V2 it is possible to automatically turn off chargers and inverters in the event of overvoltage in the cell or exceeding the permissible temperature values. Thanks to the advanced monitoring system, the system responds to adverse changes in battery performance at any time, protecting them from overheating, which significantly impacts their longevity. In systems without the GX device, the original VE.Bus BMS still functions, but the V2 version introduces a number of modern improvements that increase management safety and efficiency.

New Features of VE.Bus BMS V2 - Greater Control and Integration Capabilities

In the latest version, VE.Bus BMS V2 offers additional features that further enhance the capabilities of this system. One of them is remote on/off connector, which enables integration with other devices, such as VE.Direct and VE.Can, as well as their remote control via GX devices. This allows users to remotely manage their inverters and chargers, significantly simplifying the operation of the entire system. It's also worth noting the ability to control VE.Bus inverters and chargers from a variety of devices, such as the Digital Multi Control, the VE.Bus Smart dongle, or other compatible solutions.
Additional power terminals in the VE.Bus BMS V2 allow for powering GX devices even when the entire system has been shut down. This is a particularly useful feature in emergency situations. when the main power supply is unavailable and communication with a management device is necessary. Thanks to these solutions, VE.Bus BMS V2 offers maximum flexibility and security in energy system management.
