VW to launch all-electric up! in Frankfurt

Volkswagen has confirmed that it will lift the veil off of an all-electric version of the pint-sized up! at the Frankfurt Motor Show next month.

Likely dubbed e-up!, the small EV will be offered as both a three-door and a five-door hatchback. Apart from discreet badges on the front fenders and on the trunk lid, it will look exactly the same as its gasoline-powered counterpart, enabling it to appeal to buyers that want a low-key EV.

Tipping the scale at almost 400 pounds, the up!'s electric drivetrain will consist of an electric motor mounted in the engine bay and a lithium-ion battery pack stored under the rear bench seat. The motor will send the equivalent of 82 horsepower to the front wheels, propelling the e-up! from zero to 62 mph in a little under 13 second and on to a top speed of 80 mph.

The lithium-ion battery pack will be rechargeable in about six hours when plugged in to a regular household outlet, or in 40 minutes when using a quick charger. It will give the city a car a maximum driving range of 80 miles.

Volkswagen has hinted that the e-up! will carry a base price of roughly €19,000 (about $25,000). Buyers will lease the battery pack from Volkswagen for €60 (around $80) a month.

After greeting the show-going public in Frankfurt, the e-up! will hit showrooms across Europe before the end of the year.

Toyota to add Wireless Charging to Plug-In Prius

During the recent Toyota Hybrid World Tour Satoshi Ogiso, Managing Officer of Toyota Motor Corporation said Toyota will begin verification of wireless/inductive charging system system in Japan, the US and Europe in 2014.

We have been listening very carefully to Prius PHV owners over the past two years… and are considering their requests for additional all-electric range.

We have also heard from these owners, that they would like a more convenient charging operation. In response, we are developing a new wireless/inductive charging system that produces resonance between an on-floor coil and an onboard coil to recharge the battery without the fuss of a cable.

We will begin verification of the system in Japan, the US and Europe in 2014.

Nissan recently said they are working on an open source wireless induction charging system and that five future Nissan-brand EVs will use inductive charging.

ZF and Levant Partner to Develop Regenerative Suspension

Regenerative brakes are increasingly becoming a popular option on new cars as a way to save energy, and soon that technology could be joined by another engineering breakthrough: a regenerative suspension.

We have reported on Regenerative shock absorber developments including Linear tubular electric motors Here, Here and Here and hydraulic actuator based systems Here and Here.

This technology is being developed by ZF and Levant Power, in hopes of producing a suspension system that combines “the vast gains of active suspension with modest power consumption, minimal complexity and affordable cost,” the companies announced in a release. Essentially, the alliance hopes to build the world’s first fully active and regenerative suspension for automobiles, and make it affordable enough for volume production.

Forming the basis of the technology is an innovative, functional unit that is fitted to the outside of a ZF damper. In the compact unit is its own control unit, an electric motor and an electrohydraulic gear pump. That gear pump is in charge of regulating the oil flow to the damper, allowing it to adapt optimally and automatically to the driving conditions. In addition, the system is even capable of actively raising each individual wheel on the vehicle.

The innovative valve system automatically uses the swaying motion of the damper piston in order to recover energy. The system then guides the oil in the damper, driving the electric pump motor, essentially allowing it to function like a generator. The generated kinetic energy is then turned into electricity which is fed into the vehicle’s power supply.

“We look forward to working closely together with Levant Power. The objective is to develop the world’s first fully active and regenerative suspension, make it ready for volume production and introduce it to the market. Thus, we are promoting efficient innovations that are tailored to meet global requirements,” said Rolf Heinz Rüger, in charge of the Suspension Technology business unit of ZF’s Car Chassis Technology division.

Panasonic Announce Tokai University Solar Car Team Sponsorship

Panasonic Corporation today announced that it has agreed to provide technical support to Tokai University's solar car team, which will compete in the 2013 World Solar Challenge (WSC 2013), one of the world's biggest races for solar cars, to be held from October 6 to 13 in Australia. Under the sponsorship agreement, Panasonic will provide the Japanese university team with its HIT(R) solar cells which boast the industry's top-class electricity output as well as its high-capacity lithium-ion batteries.

The WSC, which started in 1987 and became a biennial event in 1999, is a time-based competition over a distance of 3,021km from Darwin in the north down to Adelaide in the south. Teams from around the world, including universities and corporations, participate in the race in cars powered solely by sunlight.

The Tokai University team has an impressive track record in solar car racing. The team won the previous WSC races held in 2009 and 2011, and is now looking to make a hat trick in the WSC this year. Last year, the team also won the race in South Africa that was recognized by the Federation Internationale de l'Automobile (FIA) as the world's longest alternative fuel vehicle car race. Panasonic's energy products contributed to the team's victories at these international competitions.

Panasonic's HIT solar cells have a unique hybrid configuration with a crystalline silicon substrate surrounded by ultrathin amorphous silicon layers. Compared to ordinary crystalline silicon-based solar cells, Panasonic's HIT solar cells suffer less degradation of power output at high temperatures, delivering the industry's highest-level energy output per unit of area. This makes Panasonic's HIT solar cells ideal for solar cars competing in races such as the WSC, given that the WSC regulations limit the total area of solar cells installed on the body to up to six square meters and that the cells will be exposed to the scorching Australian sun. The HIT solar modules for the Tokai University team are purpose-built for the solar car race, using the same solar cells - the main component that converts the sunlight into electricity - that are mass-produced for the residential market.

The rechargeable batteries Panasonic is providing are the cylindrical 18650 type (18 mm in diameter x 65 mm in height) high-capacity lithium-ion battery cells which use the company's proprietary nickel-based positive electrode. The high-capacity and lightweight battery cells store excess power generated by the HIT solar cells so that the car is able to continue running even on overcast days.

Bridgestone Sponsors World Solar Challenge 2013

Bridgestone will be the title sponsor of the World Solar Challenge 2013, which will be held in Australia October 6-13.

Dubbed “The Bridgestone World Solar Challenge 2013,” the event will see a record 45 teams from 26 countries compete in a 3,000 km cross-country race using only solar energy to power the vehicles.

The event will feature three separate classes, Adventure Class, which will showcase cars built for previous events; Cruiser Class, which will be judged by design practicality, and Challenger Class, which will compete for the title of the world’s most efficient solar car.
