Volvo to Develop Electric Roads for Dynamic Wireless EV Charging

The Volvo Group is now taking the next step in the development of sustainable transport solutions. In collaboration with the Swedish Transport Administration, the Volvo Group will study the potential for building electric roads, where city buses can be charged from electricity in the road at the same time as the bus is in operation. The benefit is quieter and more climate-smart public transport. A 300- to 500-meter electric road may be built for test operations in central Gothenburg during 2015.

“Vehicles capable of being charged directly from the road during operation could become the next pioneering step in the development towards reduced environmental impact, and this is fully in line with our vision of becoming the world leader in sustainable transport solutions. Close cooperation between society and industry is needed for such a development to be possible and we look forward to investigating the possibilities together with the City of Gothenburg,” says Niklas Gustavsson, Executive Vice President, Corporate Sustainability & Public Affairs of the Volvo Group.

With the use of an electric road, vehicle batteries would continuously be charged wirelessly during operation by transferring energy from the electricity grid to a vehicle, instead of charging the bus while it is standing still at charging stations. The technology being studied is called inductive charging, whereby the energy is transferred wirelessly to the underside of the vehicle by equipment built into the road.

The Volvo Group will develop a detailed proposal within the framework of innovation procurement from the Swedish Transport Administration. The proposal entails building a road section equipped with wireless charge technology and developing vehicles that will automatically charge their batteries when passing such a road section. The road will be built along a suitable bus line in central Gothenburg and be tested for public transport. Experiences from such a test track will provide valuable knowledge for future political and industrial decisions for establishing electric roads.

For several years, the Volvo Group has been offering hybrid buses with a traditional diesel engine that is supplemented by an electrical engine to reduce CO2 emissions. Three Volvo plug-in-hybrid buses are already in operation in Gothenburg (project Hyper Bus*), which charge their batteries at the end stations of line 60. The next stage of development is for these types of buses to be able to charge their batteries while in operation, thus increasing the distance the buses can run on pure electricity. And this is exactly what will be studied now. In 2015, a new bus line, ElectriCity, will become operational between Chalmers and Lindholmen in Gothenburg. This line will also provide additional knowledge of charging technology and electric power for heavy vehicles.

“We are working on both a broad and a deep basis to develop the technology of tomorrow. Electric roads are another important part of the puzzle in our aim of achieving transport solutions that will minimize the impact on the environment,” says Niklas Gustavsson.

UK motorway to charge electric cars on the move

The Highways Agency intends to equip an English motorway to test wireless charging of moving electric cars.

The Highways Agency (HA) has yet to give details of the trial site or dates. But it has issued criteria for system adoption, including a lifecycle comparable to that of asphalt (typically around 16 years), cost-effective maintenance, resistance to vibration and weather, and efficient charge collection at high speeds.

Static inductive charging experience to date in the UK involves test cars parking at existing plug-in stations in London and an electric bus service launched in January 2014 in Milton Keynes, where vehicles top up their overnight charge during drivers’ rest breaks. Managing this five-year demonstration is the eFleet Integrated Service joint venture between Mitsui Europe and consulting engineers Arup.

Arup helped create a wireless power transfer system branded HALO in Auckland, New Zealand in 2010. US wireless technology developer Qualcomm, which bought HALO in 2011, is running the London static car trial and planning a dynamic test track in Auckland.

For operational experience, the HA can look to Asia, where the Korea Advanced Institute of Science and Technology (KAIST) is running two online electric vehicle (OLEV) buses on a 12km continuous charging route in the city of Gumi. It claims 85 per cent maximum efficiency in power transfer.

The HA will also be monitoring the semi-dynamic charging trial highlighted by Transport Scotland chief executive David Middleton at a Chartered Institute of Highways & Transportation conference in March 2014. A halfway house between static and dynamic technologies, it will enable a hybrid bus to pick up charge from a series of modules installed under the road surface at strategic points along the route so it can run for long periods in fully electric mode.

A Transport Scotland spokesman explains that the approach “is likely to cause less disruption than, for example, installing dynamic charging along the length of a road”.

A similar technique is being used in Braunschweig, Germany, where a bus fitted with Bombardier Primove fast-charge technology went into passenger service on 27 March.

BYD ebus achieves 325km on one single charge in Denmark

What could be a distance record unmatched by any pure electric bus has been recorded with minimum fanfare by a BYD ebus on trial with Copenhagen Denmark bus operator City-Trafik.

The 12 metre BYD ebus completed its normal service on Route 12 a week ago, a total distance of 110km (or 68.4 miles) carrying an average of 40 passengers. Then the bus set off along the Ballerup highway – a standard motorway – and further covered a distance of 215km (or 133.6 miles) ending the day with 8% of battery charge remaining, clocking up a total of 325km (202 miles) on a single charge.

This result exceeds the previous best performance of a BYD ebus during the company's Europe-wide trial programmes. Last year an ebus achieved 310 km using only 69% of total charge between the Polish cities of Warsaw and Krackow.

A second trial of an ebus in Copenhagen with the city's other operator Arriva produced a no less impressive result. The bus completed an arduous full day of city operation – 150km (or 93 miles) from 06:00 to 16:50, operating fully loaded and with the electric heating system in constant use. The bus was then taken on a 90km (or 56 miles) motorway run and again ended up with a 8% charge remaining, covering a total distance of 240 km (149miles) on a single charge.

The two ebuses have been in service in Copenhagen since the beginning of January, in the hands of Movia's two service providers City-Trafik and Arriva. The bus, specially equipped to handle the rigors of the Scandinavian winter, has performed well. Operating costs have been low – electricity in Denmark costs 2DKK (€0.27) per kWh at normal prices. This compares with diesel at 9.79DKK (€1.3) per litre.

City of Dalian Places Order for 1,200 BYD Electric Buses

1200 zero-emission, electric buses made by BYD Company Ltd will soon hit the streets of China’s “Bright Northern Pearl”, Dalian.

Dalian’s municipal government has signed a cooperative agreement with global electric vehicle and battery leader, BYD. The agreement stipulates the purchase of 600 BYD electric buses in 2014 and another 600 in 2015, totaling 1200 units.

BYD took the opportunity at the signing event to announce the opening of a new electric bus manufacturing facility in the Dalian Huayuankou Economic Zone to service the growing needs of northern China. The agreement also mentions a conversion initiative of more than 50% of new purchased taxis in Dalian to new energy vehicles in support of the “new energy vehicles promotion and local environment improvement” initiative.

At the event with Liaoning Province Governor Zhenggao Chen, BYD Founder and CEO Chuanfu Wang introduced company milestones, R&D capabilities and products including the electric bus and fully electric e6 SUV being used worldwide in fleet applications. He also took the chance to talk about BYD’s latest consumer offering – the break-through, plug-in-hybrid, Qin.

Chairman Wang highlighted operational statistics of the BYD electric fleets now totaling over 175 million Km traveled (~111 million miles in revenue service) and operating in many cities including recent projects in London, England and New York City. A key message from the BYD Chairman was that this technology is not just environmentally friendly, but very efficient and profitable for the operators as witnessed in the Shenzhen fleets.

Zhenggao Chen, Governor of Liaoning province, expressed his view that BYD is a pioneer in the aspect of new energy vehicles, and is confident BYD will seize the opportunity to develop and keep mastering the core technologies for new energy vehicles to keep winning the war combating poor air quality.
