Battery Management System for Safe, Reliable and Efficient Energy Storage

As energy storage becomes increasingly important for both residential, commercial, offgrid and mobile use, it's crucial to have a reliable and efficient battery management system (BMS) to ensure the longevity and safety of your batteries. The 123SmartBMS is a state-of-the-art BMS that is specifically designed for lithium-based batteries, such as LiFePO4, and offers extensive integration with Victron systems.

Why You Need a Battery Management System

The 123/SmartBMS system not only monitors and controls the vital parameters of your batteries, such as voltage and temperature, but also actively balances the pack to ensure optimal performance. This ensures that the batteries are charged and discharged safely and efficiently, preventing overcharging, undercharging, and other situations that can cause damage to the batteries. This not only extends the life of your batteries but also ensures the safety of your equipment and the environment.

Features of the 123SmartBMS

The 123SmartBMS offers a wide range of features that make it the ideal battery management system for lithium-based battery packs. Some of the key features include:

Remote Monitoring and Control with Bluetooth

The 123SmartBMS system is designed to be easily accessible and manageable. With the included Bluetooth module, you can connect to the BMS system wirelessly using the SmartBMS App, available for both iOS and Android, on your smartphone or tablet. This allows you to monitor the status of your battery pack in real-time, including the voltage, current, and temperature of each cell.

With the app, you can also adjust various settings and parameters of the BMS system, such as the charging and discharging current limits, bypass voltage, as well as the battery protection thresholds. This feature gives you complete control over your battery pack, even when you're on the go. With the app, you can also access the detailed log data, so you can review the performance of your battery pack and make any necessary adjustments to optimize its performance.

Active Balancing of Your Battery Pack

The 123/SmartBMS system is designed to actively balance the voltage and capacity of each cell in your battery pack. The BMS uses a proprietary algorithm that continuously monitors the voltage and capacity of each cell and adjusts the charging and discharging currents accordingly. This ensures that all cells in the pack have the same voltage and capacity, preventing overcharging or undercharging of any individual cell, which can cause damage to the battery and reduce its overall lifespan.

The balancing function is also an important aspect of any battery management systems to maintain the overall performance of the battery pack. As all cells in the pack are at the same voltage and capacity, the energy storage system can operate at its maximum efficiency. This is especially important for applications like electric vehicles, where the performance of the battery pack directly affects the performance of the vehicle.

Building Your Own Electric Car with the 123/SmartBMS

The 123/SmartBMS is the perfect solution for those looking to build their own electric car. With our extended module, you can easily monitor and control the vital parameters of your batteries, such as voltage and temperature, ensuring the safety and efficiency of your electric vehicle. In addition, our system is also compatible with public EV chargers, making it even easier to charge your car on the go. With the 123/SmartBMS, you can be sure that your electric car will have a long lifespan, while also being safe and efficient to operate.

Integration with Victron Systems

The 123/SmartBMS has extensive integration with Victron systems, making it possible to connect one or more 123/SmartBMS to a Victron to monitor and control the Victron devices directly via DVCC. This allows for greater control and optimization of your energy storage system.

Multiple battery bank support: 

The 123SmartBMS is able to monitor and control multiple separate battery banks in parallel. This feature allows users to connect multiple battery banks with their own 123/SmartBMS system to a single control unit, such as a Victron GX device. The 123/SmartBMS Venus software will then combine the BMS information from all connected banks into a single Manager unit, which can then be used to control all connected Victron devices. This feature allows for greater flexibility and scalability in battery management systems, making it a perfect fit for larger energy storage systems or applications that require multiple battery banks.

Dual-range current sensors: 

The 123SmartBMS uses dual-range current sensors to measure both small and large currents accurately. The battery management system uses these current measurements in conjunction with other data, such as voltage measurements and temperature readings, to calculate the state of charge (SoC) of the battery. 

For a more in-depth explanation on how the state-of-charge (SoC) is measured and calculated with the 123/SmartBMS battery management system, visit our FAQ page.

Critical mode: 

The "Critical Mode" feature on the 123/SmartBMS battery management system is a safety feature that ensures the Charge signal relay is not turned off when the battery is fully charged. This feature is important in maintaining the longevity and health of the battery and is essential for the correct operation of the BMS, especially when used in combination with Victron systems. This feature can be enabled in the settings of the BMS, and is a key aspect of the system's ability to protect the battery at all times. 

DVCC support: 

The 123/SmartBMS system also offers support for DVCC, which stands for "Device Control and Monitoring Communication". This feature allows for the BMS to actively control and monitor connected devices, such as chargers and inverters, through communication with a Victron GX. By utilizing DVCC, the BMS can set "battery operating limits" or "BOL" for the connected devices, controlling the maximum charge and discharge parameters. This added level of control can further optimize and protect your energy storage system. For more information on how to enable and utilize the DVCC feature, please refer to the installation manual.
