Tesla Motors, Inc. Stock Jumps on News of Possible Charging Collaboration

Tesla may collaborate with peers on charging infrastructure, but big challenges must be overcome first.

Jun 16, 2014 at 12:20PM

Last week the response to Tesla's (NASDAQ:TSLA) announcement that it would be opening up its patents to competitors who would use them "in good faith" was somewhat flat. Would helping competitors hurt or help Tesla? The market couldn't seem to make up its mind. But now, with more related news on the matter, the market seems to be getting enthusiastic about the bold move.

Tesla stock is up about 3% this morning (at the time of this writing) after Financial Times author Henry Foy reported that Tesla, Nissan, and BMW, the world's three largest manufacturers of electric vehicles, are in "keen talks" regarding a new level of collaboration on charging networks, according to sources at all three companies.

"It is obviously clear that everyone would benefit if there was a far more simple way for everyone to charge their cars," one executive, who declined to be named, told FT.

Range anxiety
One of the most frequently cited consumer concerns about electric vehicles is range anxiety. The combination of fully electric vehicles that don't get as much range on one charge as some vehicles get on one tank of gas with a charging infrastructure that is still in its early days can cause potential electric vehicle buyers to fear the charging experience while traveling -- especially for long distances. This concern has been appropriately coined range anxiety.

Tesla, of course, has been addressing the problem with vigor. It has expanded its Supercharger network from just a handful of stations in California a couple of years ago to one that enables coast-to-coast travel.

By the end of the year Tesla plans for its network to be within range of 80% of the population. By 2015, nearly the entire U.S., or 98% of the population, will be within Tesla driving range to the expansive network.

But despite Tesla's aggressive expansion of charging stations, there are still considerable obstacles for the electric vehicle industry as a whole to overcome to rid range anxiety once and for all.

Compatibility issues
Elon Musk explained at the annual shareholder meeting earlier this month that it is not necessarily patents holding its peers back from tapping into Tesla's Supercharger network. Musk said he has been willing, for some time, to let peers tap into the network as long as they contribute their fair share of related capital in building out the network. But not one company had expressed interest in doing so before the annual shareholder meeting.

The problem? No manufacturer has yet to make a vehicle that can handle a 135-kW charge, Musk says. The prerequisite is understandable. After all, the Superchargers are known for their superior charging speed for Tesla-branded vehicles that have far more range than any other available electric vehicles on the market. The charging stations will give Tesla's 265-mile-range batteries a 50% charge in 20 minutes and an 80% charge in 40 minutes. The station will juice the Model S 16 times faster than most public charging station, Tesla claims. 

Even if peers could tap into the current Supercharger network, it would be far less useful for peers as it is for Tesla owners. Since Tesla's two battery options for its Model S get 208 and 265 miles of EPA-rated range, the charging stations don't need to be nearly as close together as they do for a car like the Nissan LEAF to benefit from on a long distance trip. For instance, in January, Tesla said its cross-country Supercharger network route had about 120 miles of spacing between each location. The density even enables owners to skip charging stations on the network while traveling across the country, if they want to. But the Nissan LEAF's limited range of 84 miles means that owners would have to stop at other non-Tesla charging stations to travel long distances.

Solving the deep-rooted problems in the current charging network for electric vehicles won't be easy. And the likely demands that Tesla will offer, including a "free forever" approach to charging and 135-kW capabilities, present interesting hurdles. Will newly available patents from Tesla give peers the needed boost to get the ball rolling on a new level of collaboration on electric vehicle technology?

Warren Buffett's worst auto-nightmare (Hint: It's not Tesla)
A major technological shift is happening in the automotive industry. Most people are skeptical about its impact. Warren Buffett isn't one of them. He recently called it a "real threat" to one of his favorite businesses. An executive at Ford called the technology "fantastic." The beauty for investors is that there is an easy way to invest in this megatrend. Click here to access our exclusive report on this stock.

4 in 5 Americans Are Ignoring Buffett's Warning

Don't be one of them.

Jun 12, 2015 at 5:01PM

Admitting fear is difficult.

So you can imagine how shocked I was to find out Warren Buffett recently told a select number of investors about the cutting-edge technology that's keeping him awake at night.

This past May, The Motley Fool sent 8 of its best stock analysts to Omaha, Nebraska to attend the Berkshire Hathaway annual shareholder meeting. CEO Warren Buffett and Vice Chairman Charlie Munger fielded questions for nearly 6 hours.
The catch was: Attendees weren't allowed to record any of it. No audio. No video. 

Our team of analysts wrote down every single word Buffett and Munger uttered. Over 16,000 words. But only two words stood out to me as I read the detailed transcript of the event: "Real threat."

That's how Buffett responded when asked about this emerging market that is already expected to be worth more than $2 trillion in the U.S. alone. Google has already put some of its best engineers behind the technology powering this trend. 

The amazing thing is, while Buffett may be nervous, the rest of us can invest in this new industry BEFORE the old money realizes what hit them.

KPMG advises we're "on the cusp of revolutionary change" coming much "sooner than you think."

Even one legendary MIT professor had to recant his position that the technology was "beyond the capability of computer science." (He recently confessed to The Wall Street Journal that he's now a believer and amazed "how quickly this technology caught on.")

Yet according to one J.D. Power and Associates survey, only 1 in 5 Americans are even interested in this technology, much less ready to invest in it. Needless to say, you haven't missed your window of opportunity. 

Think about how many amazing technologies you've watched soar to new heights while you kick yourself thinking, "I knew about that technology before everyone was talking about it, but I just sat on my hands." 

Don't let that happen again. This time, it should be your family telling you, "I can't believe you knew about and invested in that technology so early on."

That's why I hope you take just a few minutes to access the exclusive research our team of analysts has put together on this industry and the one stock positioned to capitalize on this major shift.
