WHY CHARGING AN EV HAS TO BE MESSY AND LABORIOUS?
FACTS
Each electric vehicle is designed with only one charging port, and the position of it differs for perbrand. With different parking orientations, the cables are either too long that they tangle things or people around them, or too short that it takes a lot of effort to get pluged.
WHAT IF
In this ‘era of cordless’, what if EV charging is free from cable?
Drivers can simply drive to the charging point and leave without any hassle.
HOW
The technoloy used is the same as daily wireless charging appliances. The receiver coil picks up the magnetic waves from a transmitter coil and output as electricity. The limitaton of the technology lies in the Distance Z is required to be significant smaller than Diameter D.
THE SOLUTION
The solution contains three key parts. A power supply provides stable electric power through a transmitter unit locating on the ground with the size of a parking spot. A receiver unit is designed to fit at every EV brand’s chassis with flexible housing material. The magnetic effect will guide the vehicle matching the perfect parking location. Distance Z will be lowered to an ideal position by the receiver unit, enabling a smooth effortless charging experience.
WHY MY LIFESTYLE HAS TO BE CHANGED AFTER OWNING AN EV?
FACTS
People changes lifestyle after owning an EV. They start to value a supermarket with a faster charging station over having fresher food. They change their holiday destination to lower the risk to fall short of power.
Though EVs’ range has already exceeded most of people’s daily needs, the range anxiety still creates a psychological barrier for drivers deviating too far from their routines.
The limited number of chargers, coupled with the complexity of electrical grids and charger plugs, has limited consumers from switching to electric vehicles.

WHAT IF
What if all the EVs can share the same charging infrastructure?
THE SOLUTION
Envision Cordless Charging Solution can easily be built on top of any current charging infrastructure. The power supplier unit can adapt various plugs and transfer AC/DC power supplier to the wireless power connection.
WHY EV DRIVERS HAVE TO DEDICATELY STOP & SACRIFICE TIME JUST FOR CHARGING? FACTS
Even with Tesla Supercharging - about 80% of the battery can be charged in 30 minutes, a driver still has to waste quite a bit of time compared to refueling in any gasoline car. Trips need to be planned earlier, and less quality time is available at the destination.
WHAT IF
What if charging can happen during some natural stops, for example, the long-awaited crosses or areas often with conjunctions?
average urban condition, a signal cycle is around 60-180 seconds, in which 30-90 seconds or more, the vehicle stands still await.
red light period is already 2%-5% of a 30mins normal charging time.
Charge rate of battery is not linear.
When battery state is lower than 50%, the charging efficiency is much higher - which means the low battery vechicles can gain a considerable power within very short time.
THE SOLUTION
The transmitter unit is placed not only at the charging point, but also on the long-awaited crosses. It can easily be supplied by the power infrastructure aside. When the red light is on, it detects an EV with a receiving unit and starts charging automatically.
WHAT ABOUT THE AREAS WITHOUT ELECTRICITY GRIDS?
FACTS
The best-selling EVs on the market have a range of between 240-500 km, which is more than enough to cover urban use.
While for long-distance travel, consumers are not considering electric vehicles. Part of the reason is the delay in the construction of charging stations, but another important source is the lack of power infrastructure outside the city.
If a driver wants to travel from Denver to Dallas via base model EV, it is simply not possible. There is a 355km zone that the car cannot make.
From Denver to Dallas, there is a 355km stretch with no faster changer between Amarillo and Raton.
WHAT IF
What if there is an independent power supply system that does not depend on any electrical infrastructure? It can generate and supply the energy EVs needs, and it can adapt to all types of weather and terrain?
Solar module
Collect solar energy and convert it into electricity
THE SOLUTION
Envision Energy Tunnel is an independent energy production and supply installation, which does not need to be connected to any grid or other infrastructure.
The tunnel adopts a modular approach in terms of length and modules, designed to adapt to all different road and environment conditions.
Truss frame module
Provide stability and stiffness of the tunnel, connect and support solar and/or funnel module.
Wind funnel module
Direct and accelerate airflow through the tunnel
Turbine module
Convert energy brought by the air flow into electricity.
Charging module
Wireless charging the EVs through the tunnel
THE SOLUTION
The system collects energy from the sun, wind and vehicles passing through the tunnel.
EVs can be charged for a short time while driving over the charging module. Alternatively, drivers can choose to park at the charging points, and take a break to extend the charging time.
TROPICAL AND SUBTROPICAL CLIMATE SETUP
The setup uses Solar module as main energy source. Turbine modules are an alternative, depending on the volume of traffic.
POLAR AND SUBPOLAR CLIMATE SETUP
The setup uses Wind Funnel and Turbine module as main energy source.
CHARGING MODULE
Wireless charging modules are mounted under the tunnel. EVs can be wirelessly charged per drive through.
