Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.

First Toyota unintended acceleration case headed for trial

Toyota is going to be back in the spotlight, as the first of its unintended acceleration lawsuits is headed for trial. This case covers a Los Angeles sushi shop owner, Noriko Uno. According to the what the family told The Detroit News, Uno only put about 10,000 miles on her 2006 Toyota Camry in four years. Uno was apparently afraid of high speeds, avoiding the freeway and taking a route home along LA's surface streets to avoid them.
On August 28, 2009, Uno's Camry suddenly accelerated to 100 miles per hour, eventually striking a telephone poll and a tree and killing her. The family contends that Uno attempted to step on the brakes and pull the emergency brake, neither of which brought her speed under control, while Toyota maintains that improperly installed floormats and driver error have been behind the majority of the 80 cases expected to be heard in court.
In Uno's case, The Detroit News is expecting the trial to focus on the lack of an override if the gas and brake pedals were pressed at the same time. Brake overrides were installed on Toyota's European fleet. The Uno family attorney will need to prove to the jury that it wasn't driver error that killed Noriko Uno.

Toyota Aygo X-Wave pops its top

Chop the top off a car and you'll let the sunshine and warm air in, but you'll also get a car that's heavier, less rigid and costlier. That's why European hatchbacks in particular have been increasingly favoring retractable fabric roof panels that keep the structural integrity in tact while letting the sunshine in. The Fiat 500C, Citroen DS3 Cabrio and Renault Twingo all offer this type of setup – as do the Peugeot 108 and Citroen C1, and now their Toyota platform-mate is following them down the same path. Recently announced in the UK is this Toyota Aygo with X-Wave roof option. It's a black canvas panel that opens up the space above both rows of seats at the push of a button. Unlike the roofs on some of the other aforementioned European city cars, it doesn't extend all the way down to the base of the back window, but that just means it doesn't stack up and impede cargo space and rearward visibility. Toyota is bundling the X-Wave roof option with additional equipment like upgraded lighting, infotainment system and alloys for GBP895, taxes included (equivalent to $1,355 at today's exchange rates). That's a lot less than Fiat, for example, gets for upgrading from a 500 to a 500C on either side of the Atlantic. It's also even less than Peugeot and Citroen charge for similar options on their versions of the same vehicle in the UK, and that strikes us as a pretty cost-effective way to go motoring with the top down. LESS METAL, MORE FUN WITH AYGO'S X-WAVE OPEN TOP OPTION How do you make driving a Toyota Aygo even more fun? One sure-fire way is to provide some classic open-top enjoyment with a new retractable x-wave canvas roof. Looking ahead to longer, warmer days, Toyota has launched the x-wave as an option on the five-door Aygo x-pression model. Finished in black, the roof is factory fitted and is full length, ensuring that anyone travelling in the rear seats also gets to enjoy some of the wind-in-the-hair experience. The roof is electrically operated, using a simple switch next to the map light control in the headlining. Specifying the x-wave adds even more appeal to the Aygo x-pression, which also features 15-inch alloy wheels, front fog lamps, projector headlights with LED daytime running lights, the x-touch multimedia system with DAB and Bluetooth, reversing camera and air conditioning.
