Life With 2013 Tesla Model S: Getting Supercharged In Winter

As the brand-new owner of a 60-kWh Tesla Model S, I was eager to try out a Supercharger, the ultrafast 90-kilowatt DC fast-charging stations that Tesla is establishing along Interstate highways across the country.

Model S owners–and nobody else–will be able to plug in and grab up to 150 miles of extra range in 30 minutes, about the time it takes to empty their bladders and then eat a fast-food meal and/or check their mobile devices. Astonishingly, the Superchargers are free for Model S owners.

So far, Tesla Motors [NSDQ:TSLA] has installed five Superchargers in California and two along I-95 between Boston and Washington D.C.

Tesla claims it will have more than 100 Supercharger stations by 2015, enabling the Model S to make long cross-country trips just like a gasoline car.

For me, the nearest Supercharger is at the service area on I-95 in Milford, Connecticut, about 85 miles from my home in New York’s Hudson Valley. Though my car’s EPA range of 208 miles should manage the round trip without a recharge, I figured it would be fun to try out the Supercharger experience. 

And it would be my first long trip in the car, a chance to check the accuracy of the “rated range” readout–also called the Guess-O-Meter–that so commands the attention of any electric-car driver.

Hopefully, my fate would be better than that of reporter John Broder of The New York Times, whose Model S famously ended up on a flatbed truck, out of juice, when he attempted a trip to the Milford Supercharger after leaving his Model S unplugged on a very cold night.

Unlike Broder, I started with a full charge. He had unwittingly charged the car in “Standard” mode, which–in the name of long-term battery health–stops charging at  90 percent of battery capaacity.

For my trip, just to be sure, I set the charger on “Max Range”, which takes the charge to the full 100 percent. As I pulled out of my driveway on a cool 40-degree morning, the “rated range” read 198  miles.

Still new to the car, I drove conservatively, cruising at 60-65 mph on open stretches and accelerating gently on more congested two-lane roads.  Under those conditions, the  Tesla’s “Guess-O-Meter” was spot on. After about two hours, I pulled into the northbound side of the Milford service area showing 116 miles of range remaining–82 miles less than what I started with.

So far, so good. But where the heck was the Supercharger?

The picture on the Tesla website shows what looks like a four-bay carport, conspicuously Tesla-logoed,  and flanked by a 15-foot-high sculpted phallic column of no obvious purpose. (A nod to the SpaceX Falcon 9, perhaps?) 

But I could see nothing like that anywhere around.

Eyes swiveling, I drove slowly past the parking area, past the gas pumps, past the restaurant pavilion, finally to the truck ghetto at the far end of the service area.

No carport-cum-phallus.

And now, I realized, I was stuck.  Traffic flow through the service area is one-way only. There was no going back.

I parked the car and backtracked  on foot. After a few minutes of searching, I found the Supercharger station. No carport. No phallus. Just two adjacent spaces in the regular parking lot, each with a gas-pump-like charging station and a miniscule Tesla logo.

I can now understand why John Broder drove around in circles in the parking lot at Milford. Tesla CEO Elon Musk implied that he was trying to run down the battery on purpose; Broder said he just couldn’t find the Supercharger. I can relate to that.

Luckily, both spaces were empty. But of course my car was now at the other end of the service area, marooned by “Do Not Enter” and “Wrong Way” signs.

If I wanted to charge up, my only legal recourse was to continue north on I-95, get off at the next exit, get back on I-95 southbound, drive to the next exit south, get off, get back on northbound, and return to the service area.

Fuhgeddaboudit.

I looked around for cops, saw none, and drove the wrong way back past the gas pumps to the Supercharger, encountering no other cars during my nefarious 20-second dash.

There were no instructions on the charger, just a phone number to call in case of problems. The charging plug was the same as the one I use at home.

Click the button on the plug, the charge door pops open. Plug in, and the glowing ring around the charge port turns blue, then green, and begins to pulse rapidly. Just like at home. Nothing to it.

Tesla brags that Superchargers are located at places “you’ll actually want to stop.” Not the Milford service area, a monument to low-rent fast food: McDonald’s, Subway, Dunkin’ Donuts. I used the bathroom (clean), grabbed a smoothie and a Danish, and was out of there in 26 minutes.

During that time, the car picked up 62 miles of range, bringing the Guess-O-Meter up to 178 miles, more than double the mileage home.

This fell far short of Tesla’s claimed 150 miles in 30 minutes.

There are, however, two reasons.

First, I was more than half full when I plugged in. The charging rate is very fast for an empty battery, but it slows down as the battery fills up.

Second, I have the mid-size 60-kWh battery, not the big 85-kWh model. With less capacity, my charge rate presumably falls off more quickly. (A Tesla rep on the owners’ hotline could shed no light on 60-kWh vs. 85-kWh charging rates for me.)

With my brain perhaps dulled by a fast-food sugar-and-fat buzz, I had some trouble getting the plug out. With no instructions, I did what I do at home to unplug: squeeze the button on the plug and pull.

But it wouldn’t come out. With  rising panic, I fiddled for 5 or 10 seconds, randomly pushing the button and tugging the cord. Nothing.

And then, thank God, it finally popped out, for no apparent reason.

(A Tesla hotline rep later confirmed that it takes longer for the Supercharger to shut down and release the charge cord. Might I suggest it would be nice to let Model S owners know that ahead of time?)

Fat with energy, I drove home at my normal 70 to 75 mph, and didn’t stint on the acceleration. (Nothing crazy, though.) I arrived home with 76 miles remaining, for a net “usage” of 102 miles on the meter to cover the 88 miles home.

After trying out a Supercharger, I can see its potential.  But Tesla needs to put the charging stations closer together.

The two Superchargers connecting Washington D.C., and Boston are about 200 miles apart. John Broder notwithstanding, that’s probably okay for an 85-kWh car under most conditions. But it provides little margin for cold weather, fast driving, or Murphy’s Law.

And for 60-kWh cars like mine, it just doesn’t work at all.

Okay, if I drive 55 mph and don’t use the heat or air conditioning, I might make it by the skin of my teeth. Maybe. If nothing unexpected happens.

But I’m guessing  this kind of razor’s-edge driving is not what Tesla has in mind. It’s certainly not what I have in mind; this weekend I’ll be driving to Baltimore in my trusty Chevy Volt because I’m not willing to risk the 198-mile drive in the Model S from my house to the Supercharger in Newark, Delaware.

According to  Broder, Elon Musk conceded that the Superchargers need to be 140 miles apart, not 200.

Speaking for all Supercharger-equipped 60-kWh Model S owners, I concur most heartily.

Tesla Model S Performance: Fastest Electric Car (Video)

The Tesla Model S Performance looks great on paper.

Not only does the 85 kWh Model S have an impressive 265-mile EPA-rated range, but it’ll do the benchmark 0-60 mph sprint in only 4.4 seconds.

That means the all-electric luxury sport sedan from Tesla Motors [NSDQ:TSLA] is at least as fast as V-8 German super sedans like the BMW M5.

But how do you quantify that sort of speed in the real world? If you’re Drag Times, you put it on the strip, preferably head to head against an American legend like the Dodge Viper SRT10. And then you beat it.

Yup, the near-silent Tesla made a mockery of the shiny red sports car–posting a quarter-mile time of little over 12 seconds in the process.

A second video shows the Tesla’s fastest pass, at 12.371 seconds and 110.84 mph. There aren’t a great many production cars which would do better–mostly vehicles well into the “supercar” or “hypercar” brackets, and at even higher cost than the Model S.

Some of the other statistics are outstanding too.

Drag Times recorded a 3.9-second 0-60 mph time on their VBOX timing gear. Given the Tesla’s hefty weight at the curb of 4,690 lbs, it’s even more impressive–weight is typically the enemy of speed.

Huge low-down torque helps, of course–the 416-hp Model S Performance develops 443 lbs-ft from zero to 5,100rpm, and power delivery is much smoother too.

While that driver in the Viper had to manage wheelspin and shift gears, the Tesla driver just has to sink the right pedal and keep it on the floor until he passes the 1/4-mile mark.

We’d love to see what other car giants the Model S is capable of killing.

With zero emissions and supercar-slaying acceleration, it seems you can really have your cake and eat it too.

Tesla Cuts Model S Production Goal For Third Quarter To 500, Analyst Reports

Tesla Motors said today it would cut the third-quarter production target for its 2012 Model S all-electric sport sedan, according to a stock analyst who follows the company.

A report by Wunderlich Securities analyst Theodore O’Neill notes that Tesla is now saying it would probably only deliver 500 cars through the end of September, down from a previous target of 1,000.

It still expects to deliver about 5,000 cars by the end of 2012, meaning an average of 1,500 cars a month from October through December.

The delays were attributed to unspecified production execution issues.

Green Car Reports has asked Tesla for confirmation of the report, and will update this story if we receive further information.

[UPDATE: In response to a question asking for confirmation of the report, Tesla spokesperson Shanna Hendriks replied, “Tesla’s plan has been and continues to be a focus on quality while ramping up production of Model S. This plan has not changed, and there have been no unexpected challenges or issues.”

That translates to “no comment”; you may draw your own conclusions.]

Tesla delivered its first production Model S in late June, and is now slowly ramping up production of the pioneering electric luxury sedan.

It has said it expects to deliver 15,000 cars during 2013, once its assembly plant in Fremont, California, is up to a steady production rate.

The news caused Wunderlich to downgrade Tesla Motors stock and change its recommendation to Sell, setting a new target price of $28 per share–down from its previous target of $49.

Two other analysts, Jefferies Group and Maxim Group, left their Buy ratings for Tesla stock unchanged.

Tesla Motors [NSDQ:TSLA] stock declined steadily throughout yesterday; today the stock price climbed until about 1 pm and then began to fall.
