8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

2015 Japanese Grand Prix is a little Mercedes, a lot of zen

Just one week on from the issues in Singapore Mercedes-AMG Petronas appeared to have solved its clamp problems and everything else. Daniil Kvyat at Infiniti Red Bull Racing took the two Free Practice scalps on Friday, but when it came time for qualifying the front of the grid looked really familiar: Mercedes' Nico Rosberg took his second pole position of the season, Lewis Hamilton next to him in second. Kvyat had a hand in that, too, the Russian getting into a big accident in Q3 when he put two wheels on the grass heading into the hairpin and veered into the tire wall so hard that he flipped. That ended qualifying before a number of drivers had a chance to improve their times, Hamilton among them. That's how Valtteri Bottas got in third for Willliams ahead of Sebastian Vettel fourth for Ferrari. Felipe Massa had the second Williams in fifth, ahead of Kimi Raikkonen in the second Ferrari. Daniel Ricciardo lined up sixth for Infiniti Red Bull Racing, a team we're going to have to enjoy watching for the rest of the season since it might not exist come 2016. Romain Grosjean gave Lotus some good news by getting into eighth, the team so strapped for cash that it couldn't get into its hospitality area, so it held press conferences outside and ate at Bernie Ecclestone's Paddock Club. Sergio Perez took ninth for Sahara Force India, and Kvyat slotted into tenth after not setting a time. The Russsian's race would begin from the pit lane once his mechanics rebuilt his car. It wouldn't be a Formula One start lately without someone at the front having clutch problems. This time it was pole man Rosberg, whose power unit got too hot and put him a few horsepower down on Hamilton through Turns 1 and 2. That's half of how Hamilton took the lead from the lights going out, and the Brit kept it throughout the race. Rosberg, however, said his race was lost when Hamilton pushed him wide through Turn 2, a move Hamilton defended. Rosberg finished almost 19 seconds behind his teammate, a gap that probably isn't fully explained by that opening incident. Hamilton's race was so uneventful that we almost never saw him on camera – that is, we saw him so much less than we usually see him when he's out in front and unpressured that Nikki Lauda said he'd ask Ecclestone why the cameras avoided him. The conspiracy theory holds that FOM was punishing Mercedes for not supplying Red Bull with engines next year.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
