01 · THE CHARGING EXPERIENCE

The Van Parks.
Charging Begins.

ZERO DRIVER INTERACTION REQUIRED

The most important thing about wireless charging at fleet scale isn't the technology — it's what disappears. No cable to grab. No connector to align. No behavior change required from the driver.

A fleet depot running two shifts operates on margins and schedules. Every second of charging friction compounds across a fleet of 20, 50, 200 vehicles. Plug-in infrastructure introduces a human dependency at exactly the moment you need automation.

With the WPT-50, the van enters the depot, parks over the pad, and the handshake begins automatically. ISO 15118-20 wireless communication identifies the vehicle, verifies authorization, and initiates the 50kW transfer — all before the driver has reached for their keys.

WHY 50kW
Level 2 wireless at 7–19kW needs 4–8 hours for a commercial van. A depot on two shifts doesn't have 4 hours. At 50kW, an 80% charge fits inside a shift changeover window.
🔒
WHY GROUND-EMBEDDED
No collision hazards. No cable management. No connector wear. A ground pad survives vehicle traffic, has no moving parts, and targets a 15-year infrastructure lifecycle versus 3–5 years for plug-in connectors.
📡
WHY AUTOMATIC
Drivers forget to plug in. At scale, a single missed charge event ripples through the next shift's route. Automatic initiation removes the human variable from a process that needs to be 100% reliable.

Built From
First Principles.

EVERY DESIGN DECISION HAS A REASON

The WPT-50 architecture was specified end-to-end before a dollar was raised. Not because it's complete — it's pre-prototype — but because the design decisions needed to be defensible before anyone started building.

85kHz was chosen because SAE J2954 just ratified it as the standard operating frequency for this power class. DD coil geometry was chosen for its superior lateral tolerance — a ±30mm misalignment window means a driver doesn't need to park with centimeter precision. DAB DC/DC topology was chosen because it supports both 400V and 800V battery architectures in a single hardware design.

These aren't arbitrary choices. Each one has a reason rooted in the operational reality of a working fleet depot.

🔁
WHY DD COIL GEOMETRY
Double-D geometry provides a flux path that's inherently more tolerant of lateral misalignment than circular coils. Real depot parking isn't perfect. The pad needs to work even when the van isn't.
⚙️
WHY 85kHz
SAE J2954 WPT2/Z2 class is ratified at 85kHz. Building to the stable version of a standard means vehicles arriving in 2027 will be compatible. Two years ago, this wasn't true — which is why we moved now.
🔋
WHY DAB DC/DC
Dual Active Bridge topology supports bidirectional power flow and both 400V and 800V battery architectures in one design. This means a single hardware SKU serves the current and next generation of commercial EVs — and enables V2G as a firmware feature.
