As demand grows for USB-PD 3.1 240W and BMS integration in lithium battery packs, Veloroof is packaging a program-ready integration path—hardware, firmware interfaces, diagnostics, and validation evidence—so OEM teams can execute rather than experiment. USB Power Delivery Revision 3.1 (EPR) expands USB-C power up to 240W (48V, 5A), enabling new system architectures for mobility and energy storage platforms.

USB-PD 3.1 introduces the Extended Power Range (EPR)—raising the ceiling from 100W (PD3.0) to 240W over USB-C. This matters because it turns USB-C from “charging convenience” into a legitimate system-level power interface.

• PD3.0 solution is in PVT for production readiness.
• We have acquired a PD3.1 48V/240W bidirectional module and started integration validation with our BMS stack.

A bidirectional PD3.1 interface can operate as sink/source/DRP (program-defined), enabling:

• 48V system → USB-PD voltages (e.g., 5V/9V/12V/15V/20V, program-defined) for devices and accessories
• USB-PD source → 48V system charging under controlled protection boundaries
• Deterministic transitions and safe fallback states during negotiation and fault scenarios

This capability is relevant across:

• Mobility: e-bikes / LEV platforms needing a high-power service or charging interface
• Energy storage: ESS/UPS/BBU programs needing standardized power interfaces and diagnostics visibility
• Charging infrastructure: program-defined integration for PD-based chargers/adapters

What we validated (what we observed, without over-claiming)

• Output stability under defined load profiles
• BMS communication responsiveness (program-defined interface)
• Charging efficiency behavior under controlled conditions
• Evidence collection for next-step validation (issue log + closure tracking)

We don’t sell “fast charging” adjectives. We deliver artifacts you can execute:

• Responsibility matrix: PD interface vs BMS vs main power path (limits / derating / fault ownership)
• Interface definition: signals, state transitions, diagnostics/event log fields (program-defined)
• Validation evidence package: test plan, pass/fail summary, issue log, closure tracking
• Production handoff: EOL checks, traceability fields, release notes (program-defined)

Next, we will:

• Expand validation across more operating conditions (thermal envelope, cable/connector assumptions, edge-case recovery)
• Optimize stability for bidirectional operation and role switching (program-defined)
• Evaluate integration paths into mobility platforms and energy storage systems to improve program competitiveness
