( step 1 )
Primary Pad
(Ground-Mounted)
High-frequency AC current in the primary coil creates a powerful electromagnetic field. This coil is sealed in weatherproof housing and installed flush with the pavement.
The Science Behind Wireless Fleet Charging
Wireless Power Transfer, Explained
Think of it like wireless phone charging, but for trucks and buses. WAVE’s inductive charging uses electromagnetic fields to transfer power across an air gap with remarkable efficiency and safety.
( step 2 )
Secondary Pad
(Vehicle-Mounted)
The vehicle’s pickup coil captures the electromagnetic field and converts it back to electrical energy. Advanced pairing and positioning systems ensure optimal alignment.
( step 3 )
Smart Power Electronics
Onboard converters condition the received power for battery charging, while intelligent controls optimize power transfer by communicating with the vehicle’s battery management system to match the battery state and charging requirements.
( step 4 )
Real-Time Monitoring
The vehicle's battery management system provides real-time feedback to WAVE's systems to ensure the vehicle is always receiving the optimum power level.

Safety by Design, Proven in Practice
No Live Electrical Contacts
Unlike plug-in chargers, wireless systems have zero exposed electrical contacts. This eliminates risks of: arc faults, contact corrosion, vandalism and theft.
Cord-Free Safety
By eliminating heavy charging cables, the system removes trip hazards, avoids collisions between vehicles and charging equipment, and prevents injuries from exposed metal on worn or damaged cords.
Sealed Systems
All electrical components are sealed and installed below ground level, or in an electrical cabinet, protecting maintenance personnel from electrical hazards while enabling easy access for service.

Wireless vs. Wired: The Complete Picture
Operational Advantages
| Feature | WAVE Wireless | Plug-In Charging |
|---|---|---|
Connection Time | Automatic (0 seconds) | Average 60 seconds to plug in and 60 to unplug |
Vandalism Risk | Zero (no exposed parts) | High (cables, connectors exposed, theft of copper cables) |
Equipment Lifespan | Continued operations for 7+ years | 5-7 years on average |
Equipment Damage | Sealed systems protected | Cables damaged by vehicles/weather |
Lower Total Cost of Ownership
Reduced charging infrastructure requirements (30-50% fewer units needed)
Higher vehicle utilization rates
Minimal maintenance (sealed, protected systems)
Faster ROI: Wireless charging systems typically achieve ROI faster than equivalent plug-in installations due to reduced infrastructure costs and improved operational efficiency.
