BYD Battery-Box HVB — BCU (Power Module) only

IMPORTANT (read before ordering)

This listing is ONLY for the BYD HVB BCU / Power Module (control unit / BMS).
HVB battery modules and complete HVB tower sets are sold on a separate product page:
“BYD Battery-Box HVB — Modular High-Voltage LFP Storage (2–10 Modules)”.

What the HVB BCU (Power Module) does

The BCU is the control unit required to run a BYD Battery-Box HVB tower. It provides:

• Battery management & system control for HVB stacks (SOC handling / system supervision).

• Inverter communication interface via CAN / RS485 (inverter compatibility required).

• Support for HVB platform smart functions such as automatic SOC adjustment, remote diagnosis and OTA (system/inverter dependent).

HVB platform overview (reference for compatibility)

The BYD Battery-Box HVB platform is BYD’s newest generation true high-voltage storage, using cobalt-free LFP cells developed in-house in a solid die-casting case and designed for professional ESS deployments.

Key advantages (HVB platform):

• True high voltage for highest efficiencies; round-trip efficiency ≥95%.

• High power charge/discharge: 50 A continuous and 98 A peak (15 s) (derating between -20°C and 0°C).

• Flexible scaling: 2–10 modules per tower and max. 3 towers in parallel (up to 89.07 kWh).

• Fast, problem-free installation: 1 module < 30 kg, full tower < 1.3 m, designed for single-person installation.

• Patented internal plug connection and ability to extend anytime (any SOC) (platform feature).

Technical specifications (HVB platform, for reference)

• Battery chemistry: Lithium Iron Phosphate (LFP, cobalt-free).

• Communication: CAN / RS485.

• Operating temperature: -20°C to +50°C (derating -20°C to 0°C).

• IP class: IP55.

• Warranty (platform): 15 years (conditions apply).

• Optional accessory: BYD smart WiFi/LAN module.

• Certifications listed: VDE2510-50 / IEC62619 / CEC / CE / UKCA / UN38.3.

Compatibility note (important)

HVB is a high-voltage battery system and must be matched with a supported HV hybrid / battery inverter and the required module count / voltage window for that inverter.
