Mitsubishi Turns Their EVs Into Portable Power Supplies

Mitsubishi i-MiEV owners in Japan will soon be able to use the family car as an emergency generator, using their EV’s batteries to power a home.

The MiEV Power Box is an adapter that plugs into the i-MiEV’s quick charging port. Instead of recharging the car’s drive battery, it does the exact opposite, pulling 1500 watts of electricity to keep the lights on when the power goes out.

According to the automaker, an iMiEV with a fully-charged 16 kWh battery could provide power at 1500 watts for up to six hours — enough power to run a typical Japanese household for a whole day. The compact, 25 pound adapter seems like an ideal emergency power source for homes in densely-packed urban neighborhoods, where it would be impractical to store or use a large, loud diesel- or gas-powered backup generator.

Expected to sell for about $1800 when it goes on sale in late April, the Power Box is manufactured by a Mitsubishi Group affiliate and will be offered as an official option at Japanese Mitsubishi dealers. There’s no word on whether the Power Box will sell outside of Japan, or what kinds of safeguards are in place to ensure the car’s battery isn’t damaged if it’s left discharged for a long time after an emergency, though we’d suspect a dealer-supplied solution wouldn’t void any warranties.

The Power Box is a similar setup to Nissan’s Leaf-to-Home system, a concept technology that can power a home from the drive battery in a Nissan Leaf. Interest in such systems has grown following the tsunami and Fukushima nuclear disaster that drew attention to emergency preparedness and the limitations of the Japanese power grid.

Though the Power Box only has one AC outlet and can’t be readily tied into a larger power system, it’s an early example of what EVs have to offer beyond low-emission transportation. When eventually connected to a larger, “smart” power grid, EVs won’t only get their charge from a central power source but will also be able to give up some of their stored energy during emergencies or times of peak demand.

Even on Two Wheels, the Thrustcycle Will Never Tip Over

Meet the Thrustcycle, a two-wheeled EV that relies on gyroscopes to stay upright and a flywheel for acceleration. If it ever becomes street legal, it’ll be like nothing else on the road — and it’ll never fall over.

At first glance, the Thrustcycle appears to defy gravity, balancing its 500 pounds on just two wheels. The secret to it remaining upright lies in a combination flywheel/gyroscope assembly located in the rear of the vehicle, which maintains lateral stability in direct proportion to opposing forces. Whether it’s sliding into a tight corner or getting hit by a car (or a foot, like in the video below) the gyroscope will keep the Thrustcycle standing even at a stop.

That flywheel/gyroscope assembly also recovers energy and assists the Thrustcycle’s LiFePO4 battery pack during starting and acceleration. Drivers can “tap in” to the gyroscope’s energy for bursts of speed without draining the batteries or destabilizing the vehicle, according to the designer. The Thrustcycle also features regenerative braking, and stores that energy in its flywheel kinetic energy recovery system (KERS).

“It’s unlike any driving experience,” said creator Clyde Igarashi, who said the gyroscope gives the small vehicle a feeling of weightlessness. “It’s a bit like gliding on land.”

Top speed with an average adult passenger is about 70 miles an hour, and steering is in the rear wheel. Igarashi said that setup was chosen to prove that even a two-wheeled vehicle with rear steering could remain stable with the proper use of gyroscope and flywheel, though the setup could also be applied to more conventional cars, trucks and even boats.

According to Igarashi, the Thrustcycle is a prototype and no pricing has been announced. His company is gradually working to install its technology on other vehicles while the Thrustcycle is in development.

“We will start by customizing more conventional front-steered vehicles to individual specs,” he said. Expect to see a scooter in addition to a more advanced Thrustcycle with an improved carbon fiber body and turn signals.

Some iPod Nano Owners Could be in for a Pleasant Surprise RECALL

 

 

Do you have an old first-generation iPod Nano lying around? If so, Apple wants to replace it for you, 5 years after you bought it. Such a deal.

But watch out: There’s a slight risk of your old Nano overheating, and possibly even catching on fire because of a defective battery. Apple says if you own one of the Nanos with this problem, you should stop using it immediately. The good news is, newer iPods aren’t affected by the battery defect.

Writes the company on its website:

“Apple has determined that, in very rare cases, the battery in the iPod nano (1st generation) may overheat and pose a safety risk. Affected iPod Nanos were sold between September 2005 and December 2006.

This issue has been traced to a single battery supplier that produced batteries with a manufacturing defect. While the possibility of an incident is rare, the likelihood increases as the battery ages.”

Apple’s providing a place to check your Nano’s serial numbers and order a “replacement unit.” So far, it’s unclear exactly what Apple will send you if you have the correct serial number on your old Nano. We presume the company wouldn’t dig up old iPod Nanos from the distant past, nor would it swap out the batteries in the one you have now.

So if our guess is correct, you’ll be able to trade in that old beat-up and scratched-up iPod for a shiny new one. We’ve contacted the company to find out, but we can’t imagine Apple sending anything but the latest Nano:

We’ll update this post if and when we hear from Apple. In the meantime, start digging around in those old dresser drawers — there might be an old iPod in there for you to cash in on a new one.

Volvo Puts an EV Through Crash Test Hell

Volvo takes safety very seriously, and if it’s going to start building cars with cords it wants consumers to know the technology is every bit as safe as a conventional car.

To that end, the Swedes rolled into the Detroit auto show with a Volvo C30 Electric that’s been bashed in a frontal collision test at 40 mph. We’ve shown you the video already, but it’s still interesting to see the pics and get a look at how the electric drivetrain fared.

“Our tests show it is vital to separate the batteries from the electric car’s crumple zones to make it as safe as a conventional car,” president and CEO Stefan Jacoby said in a statement. “In Detroit we are the first carmaker to show the world what a truly safe electric car looks like after a collision with high-speed impact.”

Volvo says the C30 Electric’s 24 kilowatt-hour lithium-ion battery was fully charged when the car was tested at its crash test lab early last month. The test in question is an off-set collision in which 40 percent of the front end hit a barrier at 40 mph. The battery and cables connecting the 400-volt system remained intact.

“The front deformed and distributed the crash energy as we expected,” Jan Ivarsson, senior manager of safety strategy and requirements, said in a statement. “Both the batteries and the cables that are part of the electric system remained entirely intact after the collision.”

The pack, which is good for a claimed range of 95 miles, weighs 660 pounds. It is mounted in the center tunnel where the fuel tank is found in the conventional C30. The battery is “robustly encapsulated,’ according to Volvo, and the body structure around the pack is reinforced. Putting the battery in the middle of the car provides optimal protection while centralizing mass.

The 82 kilowatt (110 horsepower) electric motor is under the bonnet where the engine would be. Ivarsson said that required reinforcing the front crumple zones because the motor occupies less space than the engine, which absorbs some of the energy in a collision.

Volvo says all of the cables are shielded for maximum protection. Crash sensors control the system’s fuses, and the same signal that deploys the airbags in a collision cuts power to the drivetrain in 50 milliseconds. Several other fuses cut power if the system detects a short circuit.

Volvo plans to roll out a demonstration fleet of 250 C30 Electric vehicles in Sweden early this year. Another fleet is slated to arrive in the United States later this year.
