Toyota begins testing wireless recharging [VIDEO]

Recharging a Toyota plug-in hybrid or all-electric vehicle could in future be as simple as parking the car. Toyota has announced verification testing is to begin later this month of a new wireless battery charging system it has developed for vehicles that use an electric powertrain.

The new technology allows a vehicle to be charged simply by parking it in alignment with a coil set into the surface of the ground. This makes the process simpler and easier, dispensing with cables and connectors.

The Toyota charging system transmits electricity using magnetic resonance created by changes in magnetic field intensity between a transmitting coil in the ground and a receiving coil in the car. It is designed so that it can reduce any loss in power transmission efficiency caused by misalignment or height differences between the coils.

The system is being developed with a future market launch in mind. Measures have been taken to minimise any electromagnetic interference with nearby equipment, and the transmitting coil in the ground has been madde robust enough to withstand vehicles driving over it.

To help the driver align the car correctly, Toyota has developed a function for its Intelligent Parking Assist system that shows the position of the transmitting coil in a parking space.

The test programme involves three plug-in hybrid used by homes in Aichi prefecture in Japan. It will assess user satisfaction, the system’s ease of use, misalignment rates and charging behaviour, such as how often charging takes place and timer-based charging it used.

Toyota will use the test results to develop the technology further, with the ultimate aim of bringing the system to market. Toyota believes its commercialisation will help promote the use of electrified vehicles and mobility options that are smarter, easier to use and kinder to the environment.

ABB to supply fast chargers for Daimler/BYD’s DENZA EV

ABB has announced it will enter into a partnership with Shenzhen BYD Daimler New Technology Co to supply direct-current fast chargers over the next six years.

The announcement said the agreement will result in the world's largest fast-charging network for electric vehicles.

According to the two companies, the wall-mounted chargers will have a number of innovations designed for user convenience and safety including a mobile app that allows cloud-based remote monitoring and control of charging sessions.

First deliveries are expected by the middle of the year. The chargers will be sold through BYD-Daimler's Denza dealerships along with the vehicle.

The first Denza dealership will open in Beijing and more dealerships will be built up simultaneously in Shanghai and Shenzhen.

Established in 2010 between BYD Co, a leader in China's electric vehicle industry, and German automotive icon Daimler AG, BYD-Daimler was the first joint venture in China specializing in developing and producing new-energy vehicles.

The joint venture's Denza brand launched last year will have its world premiere at Beijing auto show in April. It is slated to go on sale later this year, according to an earlier announcement.

Ulrich Spiesshofer, CEO of ABB Group, said at a news conference in Stockholm that he is confident about the deal with BYD-Daimler.

"We are honored to be a partner in this venture with BYD-Daimler to move urban transportation forward in a more sustainable way. By combining car and fast charger sales, Denza is taking a bold step to address a key obstacle for potential electric car buyers," said Spiesshofer.

"ABB's electric vehicle charging solutions have been expanding rapidly worldwide as the underlying technology combines our key strengths in power electronics, software, service and power distribution."

The fully electric Denza is designed for journeys of more than 250 km and will be among the first long-range electric vehicles on the Chinese market.

Market research shows that consumers value long drive ranges but at the same time expect short charging times.

Denza will offer its customers the convenience of charging their cars in a short time at home, at the workplace or at compatible public places, according to BYD-Daimler.

"The Denza represents a significant step in sustainable transportation for the Chinese automotive market. It was vital that we have the right partner to support this innovative concept," said Arno Roehringer, COO of BYD-Daimler.

"ABB is the ideal technology partner for us as they have proven themselves with electric vehicle chargers in China as well as globally and - equally important - the service to install it," he added.

The Chinese government adopted a GBT standard for direct-current fast charging to encourage technical innovation and stimulate market acceptance of electric vehicles.

Analysts said that urban charging infrastructure is key to widespread acceptance of electric vehicles by consumers.

The GBT standard will give Chinese consumers the option of charging their vehicles at home or in public, with DC fast charging expected to be rolled out in the near future.

Experts say China's electric vehicle market could quickly gain momentum due to technology, market innovations, the GBT national fast-charging standard and favorable incentives.

ABB has worked on pilot projects with local automakers and utilities in China since 2010. In 2013 it began to build up a local electric vehicle organization to support growth including R&D, manufacturing, logistics and services.

First all-electric BYD E6 taxi fleet launched in London

Chinese carmaker BYD will launch London’s first ever all-electric taxi fleet on Tuesday, pulling ahead of global rivals such as Nissan in the race to roll out zero emission cabs by 2018.

Following similar BYD E6 taxi fleets in China, Hong Kong and South America, BYD’s move into London transport comes ahead of a 2018 deadline set by Mayor Boris Johnson for all of the city’s taxis to be zero-emission, which has sparked a battle between manufacturers to develop green vehicles.

The Chinese manufacturer, 9.9 per cent owned by Mr Buffett, will initially launch a fleet of 20 electric cars operated by Thriev, a taxi company, less than two months after supplying the first-ever fully-electric buses to the capital.

“Londoners are typically early adopters to new technology . . . and we are very happy to be first and beat the deadline by a few years. This is where the electric vehicle technology will shine,” Isbrand Ho, managing director of BYD Europe told the Financial Times.

Although the E6 cannot be registered as a ‘Black Cab’ because of the turning circle requirements, Thriev is aiming at the established 50,000-strong mini cab market, which relies heavily on diesel-powered MPVs.

The BYD E6 is powered by a 40kWh battery and should offer a range of around 180 miles on a single charge, according to Isbrand Ho, managing director of BYD’s export division. The E6 was launched as a taxi in Hong Kong last March and a fleet is already operating in Shenzhen, the Netherlands and Columbia.
