BCU Lithium Battery BYD Battery Box HVE (BCU+Base) - 17161480-00

The BYD Battery Box HVE BCU - 17161480-00 is the essential component that enables any configuration of the Battery Box HVE system. This battery control unit (BCU), with base included, acts as the communication and management core of the system.
It is designed to safely and intelligently control HVE 4.2 or HVE 6.4 battery modules in high-voltage storage systems.
The BCU manages loading and unloading, ensures system protection and optimises system operation.
It also improves operational efficiency and extends the lifetime of the assembly. Without this unit, the modules cannot operate or communicate properly, which prevents them from making full use of their capabilities.
The BCU enables the modules to be controlled, monitored and protected, facilitates structural scalability and integrates intelligent functions.
Thanks to its modular design, it is quick and easy to install. It is the key to modern, safe and future-proof energy storage systems.

Features of the BCU Lithium Battery BYD Battery Box HVE (BCU+Base) - 17161480-00

The HVE BCU acts as the brain of the system: it monitors each connected module, regulates charging and discharging, automatically balances the cells and protects against overloads, over-discharges and short-circuits.
Their presence is essential to configure towers of 2 to 4 HVE modules connected in series, with a capacity of between 8.6 kWh and 25.8 kWh.
It also makes it possible to connect up to three towers in parallel, increasing the total capacity to more than 70 kWh.
In addition, without this unit it would not be possible to build and expand an HVE tower properly or to access the full potential of the modules.

Design and structure

With a robust and compact design, the HVE BCU includes a structural base and wall bracket, making it easy to mount and securely fix to a wall or floor, adapting to residential or commercial spaces.
Safety is another pillar of this unit's design. Thanks to its advanced protection technology and internal balancing system, the longevity of the unit is guaranteed, in line with the expected durability of BYD battery modules.
In addition, the structural base of the BCU acts as a physical support for the HVE tower, ensuring mechanical stability and facilitating the assembly of up to four modules in series, even in confined environments.
Thanks to the plug-and-play design, no wiring is required between modules. This simplifies assembly, saves time and reduces installation errors. The unit is built for long-term use and comes with a 15-year warranty, just like BYD battery modules. Battery Box HVE.

Connectivity and communication

In terms of connectivity, the BCU communicates with HVE battery modules via CAN and RS 485 interfaces, enabling seamless integration with compatible inverters and energy management platforms.
It is fully compatible with BYD's official application, which offers remote monitoring, real-time diagnostics and automatic OTA (over-the-air) updates.
In addition, the system automatically detects the connected modules. This allows efficient self-configuration, adjusting voltages and optimising operation from the first switch-on. This automation reduces technical intervention and speeds up commissioning.
The BCU also incorporates critical functions for back-up in case of power failures, making the system a reliable solution for self-consumption and backup.
