Recharge Wrap-up: Automakers talk connected cars, Toyota's CNG hauler

Tesla, Toyota and General Motors addressed the House Subcommittee on Information Technology about the security and benefits of "The Internet of Cars." Tesla put forth four suggested security principles for the security of connected cars. Those include standard cryptography ("signing") used by automakers, measures to prohibit direct connection over the internet, isolation of a car's networked systems from its mechanical systems and standard encrypted communications protocols. Tesla VP of Business Development Diarmuid O'Connell also urged against "overly restrictive regulation." O'Connell says, "Regulation at a time of rapid innovation runs the risk of limiting the realization of the full extent of safety advances."

The partners will add 500 fast-charging sites to the eVgo network in 25 cities by the end of 2015. The "Fast Combo" chargers will be available to use for free for BMW i3 customers for 24 months. The free charging only applies to new buyers, though, leaving behind some 15,000 current i3 owners. Still, many EV drivers – not just BMW owners – will benefit from the ability to charge quickly in more places. Read more at Green Car Reports. Toyota has announced its first CNG car hauler. The automaker's in-house transport company, Toyota Transport, will operate the truck out of Long Beach, California. The truck, which Toyota says emits 85 percent less particulate matter and 10 percent less CO2, will drive about 7,000 to 8,000 miles per month. "We started exploring the CNG option more than three years ago, and it has been worth the wait," say Toyota Transport Compliance Senior Analyst Kirk Welch. "Natural gas is the cleanest burning fossil fuel and will help Toyota advance our environmental efforts to reduce fleet emissions." Read more in the press release below. Making Your New Toyota Run Cleaner Before You Even Start It Toyota's Latest Car Hauler Runs on Compressed Natural Gas November 23, 2015 TORRANCE, Calif. (Nov. 23, 2015) – Toyota Transport, the automaker's in-house vehicle transportation trucking company, now has its first car hauler that runs on Compressed Natural Gas (CNG). The Long Beach, CA based truck/trailer does what any other car hauler can do, except it does it while emitting 85 percent less overall particulate matter and 10 percent less carbon dioxide.

Tesla Model S drivers put way more miles on their cars than Nissan Leaf owners do (we think)

Just a few weeks ago, Nissan announced that its customers have driven over a billion electric kilometers in the four years that the world's best-selling EV has been on the road. That heady milestone means, Nissan says, that the Leaf has saved 180 million kilograms of CO2 emissions around the world. The billion kilometers have been split among the 147,000 Leaf vehicles that Nissan has sold. Well, not really, since the billion kilometer total only counts Leaf EVs registered with CarWings, which Nissan says is 54 percent of the total sales. That's 79,380 cars and results in an average – and it's only a rough average, but what're you gonna do? – of 12,597 miles per car. Let's keep that number in mind for a minute. Today, despite going on sale a year and a half after the Leaf (June 2012 versus late 2010), Tesla Motors Tweeted today that Model S drivers have hit the same numerical milestone. Tesla didn't say how many of its vehicles were involved in its count, but we think that Tesla has sold at least 50,000 Model S electric vehicles globally (about 2,650 in 2012, 22,450 in 2013, 21,821 for 2014 through the end of September), so we'll estimate a rough average for each Model S of 20,000 miles. So, in case anyone ever needs numeric proof that a Model S is more fun to drive than a Leaf – that's the only possible thing this could mean, right? *ahem, longer range* – now you've got the data. {C} This content is hosted by a third party.

Nissan says "thanks a billion" to LEAF owners Nissan LEAF drivers registered on CarWings telematics have collectively driven ONE BILLION KILOMETERS worldwide* Globally, Nissan LEAF drivers have saved more than 180 MILLION kilograms of CO2 emissions* Over 147,000 Nissan LEAF vehicles have been sold globally to date ROLLE, Switzerland – Nissan has revealed that owners of the LEAF, its 100% electric car, have collectively recorded an impressive one billion kilometers on the CarWings telematics system worldwide – saving over 180 million kilograms of CO2 emissions* in the process. This incredible achievement comes almost four years since the LEAF was launched in 2010 as one of the first mass-market, pure-electric vehicles. It is now the best-selling electric vehicle in history, with over 147,000 LEAF vehicles sold globally to date, 31,000 of which have been sold in Europe.

For Tesla, the energy-storage company, the magic is in batteries

Tesla Motors Chief Elon Musk has always been a big-picture guy, and the company's chief technology officer appears to be following suit. JB Straubel, who was a keynote speaker at the Joint Venture Silicon Valley symposium near the automaker's Northern California home base recently, says the company is just as much an energy-storage company as a car maker. And he said the rate of battery-technology improvement shows no signs of slowing down, according to Green Tech Media. Straubel estimated that battery performance has improved about 40 percent during the five years between the debuts of the Tesla Roadster and the Model S. Additionally, battery density has doubled during the past decade and continues to ramp up fairly steeply. He noted that further near-term improvements will come not from the size and shape of the cell, but from improved cathode and anode materials. Those energy improvements won't just help the cars. Tesla uses a two-megawatt-hour battery pack to supply as much as 10 percent of the peak energy used at the company's factory in Fremont, CA, and will double the size of that battery-powered energy capacity within the next few months, Straubel says. Automakers like Tesla and Nissan are licking their proverbial chops at the prospect of substantially improved battery performance paired with declining battery costs as more and more lithium-ion battery packs get produced. Late last year, Navigant Research estimated that lithium-ion battery costs would fall by almost two-thirds by 2020, down to a low $180 per kilowatt hour. That should make electrified powertrains price-competitive with conventional vehicles, as electric vehicles could then command a price premium as low as $2,000 compared to their gas-powered brethren.
