BYD B-Box Premium HV 2.0 power module for HVS or HVM

BYD B-Box Premium HV Battery Control Unit 2.0 + Base 16448287-00.

BYD's proven HVS and HVM high-voltage series have received a practical update with the new BCU 2.0. Thanks to external plug-in ports, removing the cover plate to connect communication and power cables is a thing of the past. Standard RJ45 and MC4 connectors now allow for faster and easier installation. When using the supplied connectors with the BCU 2.0, use a suitable crimping tool and follow BYD's instructions .

• Suitable for high-power emergency backup and off-grid functionality.
• Highest efficiency thanks to a true high-voltage series connection.
• The patented modular plug design requires no internal wiring, providing maximum flexibility and ease of use.
• Cobalt-free lithium iron phosphate (LFP) battery: Maximum safety, lifespan and power.
• Compatible with leading 1 and 3 phase high voltage battery inverters.
• Two different modules for a full range of system sizes.
• Highest safety standards such as VDE 2510-50.

A Battery-Box Premium HVS consists of two to five HVS battery modules connected in series to achieve a usable capacity of 5.1 to 12.8 kWh. Up to three identical modules can also be connected directly in parallel. The Battery-Box Premium HVS allows for a maximum capacity of 38.4 kWh. Scalability is possible by adding HVS modules or parallel HVS stacks later.

A Battery-Box Premium HVM consists of 3 to 8 HVM battery modules connected in series to achieve a usable capacity of 8.3 to 22.1 kWh. In addition, direct parallel connection of up to 3 identical Battery-Box Premium HVMs allows for a maximum capacity of 66.2 kWh. Scalability is possible by adding HVM modules or parallel HVM stacks later.

The BYD battery from the HVS series, which stands for High-Voltage Small, has the lowest capacity, as the name suggests. A standard pack consists of two battery modules with a combined capacity of 5.1 kWh. The HVS is expandable to a maximum of five modules, achieving a total capacity of 12.8 kWh. Each individual module has a capacity of 2.56 kWh with an internal voltage of 102.4V. Whether you can use a total of five modules depends on the battery or hybrid inverter used. You can connect up to three battery towers in parallel—3 x 5 battery modules—for a maximum capacity of 38.4 kWh.

The BYD HVM battery, or High-Voltage Medium, is more powerful than the HVS. A basic pack consists of three battery modules with a combined capacity of 8.3 kWh. This model can be expanded to a maximum of eight modules with a combined capacity of 22.1 kWh. Each module has a capacity of 2.76 kWh and an internal voltage of 51.2V.

This model also has a minimum requirement. You must use at least three modules for a functioning battery. A maximum of three identical systems can be connected in parallel – so 3 x 8 – achieving a maximum capacity of 66.2 kWh.
