高通这家半导体制造商是从静态的无线充电技术基础上建构了这套动态充电技术(DEVC)
能够以20kW的速率对车辆充电，并且同一轨道上的两个方向都能够充电。
另外其他公司，像是本田，也在发展同样的技术，只是充电功率要高得多。

Qualcomm unveils electric vehicle dynamic charging tech – built a 100m
test track with 20kW charging
Despite the fact that electric vehicle charging rates have been improving
rapidly and should soon solve the charging issue, there are still a few
companies working on dynamic charging technology (DEVC) as a potential
solution for charging times.
Qualcomm is the latest company to unveil a DEVC system this week. They
demonstrated their technology on 100 meters of road in France that can
charge electric vehicles at up to 20 kW while they are driving on the
road.
The California-based semiconductor manufacturer built the technology on
top of its wireless charging tech:
“Based on the Qualcomm Halo™ wireless electric vehicle charging
technology (WEVC), Qualcomm Technologies designed and built a wireless
DEVC system capable of charging an electric vehicle (EV) dynamically at
up to 20 kilowatts at highway speeds. Qualcomm Technologies also
demonstrated simultaneous charging, in which two vehicles on the same
track can charge dynamically at the same time. The vehicles can pick up
charge in both directions along the track, and in reverse, further
showcasing how the Qualcomm Halo DEVC system has been designed to support
real-world implementation of dynamic charging.”
They built a test track project called ‘FABRIC’ in Satory Versailles.
Two all-electric Renault Kangoo vehicles were fitted with the receiver
and they will be running tests for efficiency until the end of the year.
“We are inventors. We are WEVC. This dynamic charging demonstration is
the embodiment of this. I am immensely proud of what we have achieved.
The combination of a global team of expert engineers and Qualcomm Halo
technology, which covers all aspects of WEVC systems, irrespective of the
magnetics used, has enabled us to really push the boundaries of the
possible and outline our vision for future urban mobility.”
VEDECOM was also involved in the project along with Qualcomm and Renault.
In the short-term, dynamic charging is not expected to be an important
part of the electric charging infrastructure in the automobile industry.
But in the long-term and with the advent of autonomous driving, we could
see the technology being used on sections of highways in order increase
the on-road time of some vehicles, especially trucks.
Other companies, like Honda, are working on the same concept, but with a
much higher charge rate.
