How Does High Voltage Battery Communication Failover Work?
Understanding Master and Slave Battery Communication
Large battery energy storage systems can contain multiple battery units working together. When several batteries are connected as part of a larger system, communication between the battery units and inverter becomes an important part of system management.
The Rhino IntelliFlex High Voltage Battery incorporates a CAN communication failover system designed to maintain communication if the Master battery becomes unavailable.
What Is CAN Communication?
CAN, or Controller Area Network, is a communication method used by electronic systems to exchange information. In the Rhino IntelliFlex architecture, CAN communication allows the battery system to communicate with the inverter and coordinate battery operation.
The system uses a Master and Slave arrangement.
What Happens if the Master Battery Fails?
LBSA describes the Rhino IntelliFlex as having seamless CAN communication failover.
The process is designed to work as follows:
- The Master battery experiences a failure.
- A Slave battery detects the loss through the CAN communication line.
- The Slave battery takes over the Master role.
- Communication with the inverter continues through the newly assigned Master.
LBSA states that this automatic failover is designed to maintain uninterrupted inverter communication.
Why Is Failover Important in Large Battery Systems?
For commercial and industrial energy storage, communication is an important part of system control. A battery system may have multiple units operating together, making dependable communication particularly relevant as the installation grows.
The Rhino IntelliFlex is designed for expansion, with LBSA specifying the ability to scale up to 60 batteries in parallel.
| Rhino IntelliFlex Feature | Purpose |
|---|---|
| CAN Communication | Enables communication between system components |
| Master/Slave Configuration | Coordinates multiple batteries |
| Automatic Failover | Allows a Slave to take over if the Master fails |
| Modular Expansion | Supports larger battery configurations |
Designed for Scalable Energy Storage
Communication failover is one of several features incorporated into the Rhino IntelliFlex High Voltage Battery. Combined with modular architecture, battery synchronisation and hot-swappable modules, it forms part of LBSA's approach to scalable commercial and industrial energy storage.
For businesses considering a larger high voltage battery installation, understanding communication architecture can be just as important as understanding storage capacity.
