DOG WHISTLE

Compact PLC communications modules built on Lumissil HomePlug® Green PHY silicon. Drop one into your EVSE — or your EV — and add ISO 15118-ready communications without designing PLC hardware from scratch.

The M.2 version with onboard MCU carries the CerberusEV software stack — SLAC, Green PHY, EXI, TLS, Plug & Charge PKI, bidirectional power transfer. You add a socket.

Dog Whistle PLC Modules

Three Versions. One Powerful Platform.

Dog Whistle provides compact, high-performance PLC connectivity for EV charging and other embedded energy applications. Every version is built around Lumissil HomePlug® Green PHY silicon, with the interface and processing architecture chosen to fit your design.

Pin Header Module

Designed for products that already contain an application MCU. The module provides the PLC physical-layer hardware over dual pin-header rows and communicates with your host processor.

Why Dog Whistle

INTEGRATED. The hard part, handled.

ISO 15118 is becoming table stakes for chargers and vehicles alike — and building the stack in-house means PLC hardware design, EXI codecs, PKI infrastructure, and years of conformance testing. Dog Whistle puts all of it on one card.

🧩 Drop-in integration

One standard M.2 2242 socket adds ISO 15118 to any EVSE or EV controller. No PLC analog front end to design, no EXI codec to write, no stack to maintain.

V2G built in

ISO 15118-20 bidirectional power transfer sessions, negotiated and managed on-module. Your firmware sets limits; Dog Whistle runs the protocol.

🔋 DER native

IEEE 2030.5 (SEP 2.0) client with CSIP profile support for utility DER programs, aligned with IEEE 1547-style interconnection requirements.

🔐 Plug & Charge, complete

Full ISO 15118 PKI: TLS, contract certificate handling, secure-element key storage, and certificate installation and update flows.

🔀 Both sides of the cable

Field-selectable SECC (charger-side) or EVCC (vehicle-side) operation. One part number covers your EVSE line and your vehicle platform.

📅 Compliance on schedule

NEVI and emerging procurement rules increasingly require ISO 15118 and Plug & Charge. Meet them without staffing a protocol team.

Specifications

COMPLETE. The full stack on one card.

Everything between the Control Pilot line and your application firmware, pre-integrated and conformance-tested.

Design-In

DESIGNED IN. Socket to ship in three steps.

Dog Whistle is built to disappear into your product. No RF layout review, no protocol team, no new certifications scoped from scratch.

01
Drop in the socket

Place a standard M.2 2242 socket and the Control Pilot coupling circuit from our reference schematic. That is the entire hardware change.

02
Connect your host

Talk to the module over UART, SPI, or USB with a simple message API. Charge control stays in your firmware; the protocol stays in ours.

03
Ship it

The stack is developed and validated against ISO 15118 test tooling, so your engineering effort covers your product — not the protocol.

The design-in package includes a carrier reference design with the Control Pilot coupling front end, EMC layout guidance, host API documentation with sample code, and a dev kit that runs the full stack on your bench before your board exists.
