WAVE (Wireless Advanced Vehicle Electrification) has demonstrated a 250 kW Wireless Power Transfer System prototype. The company will deliver the new charging system to the Antelope Valley Transit Authority (AVTA) in California later this year.
WAVE’s technology transfers power from a charging pad embedded in the pavement to a receiving pad mounted on the vehicle’s undercarriage seven to eight inches above. The system allows AVTA’s electric buses to charge during layovers as passengers board and disembark. This “top-off” charge capability extends the effective range of an e-bus, or it can allow a bus to operate with a smaller battery pack.
“This is yet another important step in AVTA’s push to go completely zero-emission by 2018,” said AVTA Board Chairman Marvin Crist. “The acquisition of these chargers strengthens the infrastructural foundations that will allow our fleet to seamlessly complete any route within our service area. The example that AVTA is setting will form a blueprint that any transit agency looking to go completely zero-emission can follow.”
