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.

Is 120 miles just about perfect for EV range?

When it comes to battery-electric vehicles, our friend Brad Berman over at Plug In Cars says 40 miles makes all the difference in the world. That's the approximate difference in single-charge range between the battery-electric version of the Toyota RAV4 and the Nissan Leaf. It's also the difference between the appearance or disappearance of range anxiety. The 50-percent battery increase has zapped any lingering range anxiety, Berman writes. The RAV4 EV possesses a 40-kilowatt-hour pack, compared to the 24-kWh pack in the Leaf. After factoring in differences in size, weight and other issues, that means the compact SUV gets about 120 miles on a single charge in realistic driving conditions, compared to about 80 miles in the Leaf. "The 50 percent increase in battery size from Leaf to RAV has zapped any lingering range anxiety," Berman writes. His observations further feed the notion that drivers need substantial backup juice in order to feel comfortable driving EVs. Late last year, the Union of Concerned Scientists (UCS), along with the Consumers Union estimated that about 42 percent of US households could drive plug-in vehicles with "little or no change" in their driving habits, and that almost 70 percent of US commuters drive fewer than 60 miles per weekday. That would imply that a substantial swath of the country should be comfortable using a car like the Leaf as their daily driver - with first-quarter Leaf sales jumping 46 percent from a year before, more Americans certainly are. Still, the implication here is that EV sales will continue to be on the margins until an automaker steps up battery capabilities to 120 or so miles while keeping the price in the $30,000 range. Think that's a reasonable goal to shoot for?

2014 Toyota Tundra gets five grades priced from $25,920*

Toyota has announced pricing details for its refreshed 2014 Tundra, with the fullsize pickup offered in five grades. Naturally, that doesn't include the buyer's choice of three cab styles, the option of two- or four-wheel drive, and a choice of a 4.0-liter V6 base engine or 4.6-liter and 5.7-liter V8s.
The base SR starts at $25,920, while the volume SR5 model starts at $29,465. Toyota notes that all SR5s ordered with the big V8 hold the line on pricing from 2013 while including a further $650 in standard equipment. The first of three high-end trims, Limited, starts at $36,940, while the Platinum and 1794 Edition both start at $44,270, with all prices subject to a $995 destination charge. Also noteworthy on the cost-savings front, Limited CrewMax 4x4 models are priced $2,000 less than their 2013 equivalents, (4x2 buyers save $1,900).
As is typical for a model as as customizable as a pickup, Toyota's pricing structure is far from simple. Adding the 5.7-liter V8 at one trim level can cost several hundred dollars more or less than another trim level - the same goes for adding four-wheel drive. So, rather than break out the Enigma Machine to try and decipher what options cost what on which trim, we've just rolled the whole pricing chart in. Scroll down for a look, including Toyota's full press release, and then check out our recent First Drive feature of the truck.
