Electric Road System

Elonroad is a hightech electric road concept. It auto charges all types of electric vehicles when parked as well as when driving. Electric roads extend driving range and reduce the need of large and heavy batteries.

Vision

Our vision is to electrify the entire transport sector and make fossil fuel a thing of the past. With clean energy from the sun, wind and sea in an emerging charging infrastructure that is accessible for everyone, and with gradually more and more self-driving vehicles shared in an smart way, drastically reduced CO2 emissions will follow.

How it works

ELONROAD involves a conductive rail laid on top of the road. A conductive picup under the vehicle connects to the electric rail via sliding contacts. The rail is only active when covered by the vehicle, this makes it safe in city environment.

Works for all types of vehicles

The Elonroad electric road system works for all electric vehicles, cars, taxis, buses and trucks.

ELECTRIC ROAD

Charge the vehicle while driving

BUS STOP CHARGER

Quick charger for bus stop

GREEN CITY TRANSPORT

Electric public transportation

AUTOMATIC PARK CHARGER

A  car park charger for all vehicles

LONG HAUL TRUCKS

Electric road charger for heavy trucks

MINING INDUSTRY

Heavy-duty electric road for dumpsters

PLACED ON THE ASPHALT

Elonroad is easy to install with only little effect on the asphalt. This reduces installation time and facilitates service and maintenance.

SAFETY

Its unique design admits short rail segments to be powered separately . This leads to a safe electric environment.

EFFICIENT

Elonroads electric road and park charger transfers high power up to 300kW with a 97% efficiency.

ECONOMICAL

The cost for two lanes of electric road is preliminarily calculated to be 1 MEuro/ km. Over a 10 year perspective the cost of electric road + used electricity = the cost of otherwise used diesel or bio fuel.

To make electric roads profitable 1km of road needs to be used approximately 1 000 times a day. The reduction of CO2 emissions will make it even more beneficial.

WORKS FOR ALL

The Elonroad electric road system works for all electric vehicles,
cars, taxis, buses and trucks. Compared with overhead lines that doesn´t work for cars. Cars stand for 60% of the transport greenhouse gases.

GREEN TRANSPORT

In Sweden the transport sector stands for 30% of greenhouse gases.
A shift to electric transports would help reach the goal of slowing down climate change.

GREEN ELECTRICITY

The electricity needed for all vehicle transports would be about 10-15% of the total consumption. Investments in clean energy should go hand in hand with charging infrastructure.

Demonstration of electric road in Lund 2020-2022

EVolutionRoad has been given a go-ahead to build a unique test and demonstration site with ELONROADs unique electric road system in the city of Lund. The purpose is to contribute to increasing knowledge about electricity routes as part of the future fossil-free transport system.

The assignment comes from the Swedish Transport Administration. It´s the first electric road with ground level feeding system tested for a city bus and other vehicles in a city environment. The project is a test and demonstration project. Duration 2019-2022.

The consortium includes nine actors from the business sector, universities and the public sector: Innovation Skåne AB (project manager) Elonroad AB Kraftringen Energi AB Lund municipality / Future by lund Lund University of Technology, LTH, Ramboll AB Skånetrafiken AB Solaris Sverige AB National Road and Transport Research Institute, VTI.

The Swedish Transport Administration finances SEK 83 million of the project’s total budget of SEK 96 million. Other funding comes from players that have joined forces in the Elväg Syd consortium.

Electric roads reduces the need of large heavy batteries.

How it works

The Rail

ELONROADs concept involves a conductive rail. It can be laid on top of the road or merged down. The on top version is 4cm high and 35 cm wide with inclined sides of only 10 degrees to make it smooth when changing lanes.

It´s glued to the asphalt via mounting plates.

The submerged rail is merged down into the asphalt, has a flat top aligned with the surrounding asphalt. It´s 25 cm wide and 5cm deep. Because it´s completely flat it works well on High Ways

The Pic Up

The Pic Up connects to the electric road. It´s placed under the vehicle and offers an economic and simple solution for all types of vehicles. The Car mounted Pic Up is only 2 cm high and can be retrofitted under EVs. For an electric bus and trucks the Pic Up is bigger. The hight is 5-6 cm 240cm in length.

It slides along the rail and transfer the current up to the vehicle. With three sliding contacts in a smart arrangement it reaches plus and minus poles simultaneously. An onboard DC/DC converter charges the batteries when using the electric road.

Batteries

All vehicles will have batteries that will supply energy for driving on non-electric roads. The electric road is a charging infrastructure placed on major roads and highways. The rail is built in intervals. Batteries take over automatically at exits and roundabouts.

The electric road concept reduces the need of heavy and expensive batteries with 20-70%.

It depends on the distance between electric roads and destination.

Range anxiety

We solve the problem with range anxiety. The electric road is an effective range extender. The rail can deliver up to 300 kW while driving. This is enough for a long-haul truck to power both propulsion and charging at the same time.

For example one kilometer of driving on the electric road gives a total energy to drive three kilometers.  Two kilometers is after the truck has left the electric road. This saves investment costs for the infrastructure. Working together with the onboard battery electric roads only needs to be placed on 30-50% of the stretch for infinite driving range.

Power stations

The rail is powered from power stations located at the side of the road.

The capacity of the supply stations is capable of delivering up to 3 MW to the rail, which is enough for 10 trucks running on the connected electric road. The power station is connected to the grid every 1 km and transforms grid voltage from 10kV to 600V DC. In that way energy losses are minimized.

Weather conditions

The rail can be heated to melt snow and ice when needed.

To remove snow from the road Elonroad has developed a special snow plow. It can remove the snow as a regular plow. It´s been tested in Swedish winter conditions.

In the case of a road surfaces covered with sludge and road salt that conduct current, leakage currents are prevented through earthed ledge out towards the asphalt. In addition, a control measurement of is performed so that power can be safely switched on.

The on top mounted rail stands on grooved rubber so that rainwater can easily flow under the rail as the asphalt usually slopes a little to the side.
