Tesla Preps Bigger 100 KWh Battery For Model S and Model X (theverge.com)

An anonymous reader writes: Tesla will soon offer a 100 kWh battery for the Model S and Model X that will allow for increased range -- perhaps as much as 380 miles for the Model S. Currently, the 90 kWh batteries are the company's largest capacity. Kenteken.TV is reporting that the Dutch regulator that certifies Tesla's vehicles for use in the European Union, RDW, has recently published a number of new Tesla variants. RDW's public database now includes entries for a Tesla "100D" and "100X," which are titles that follow Tesla's current naming system based on battery capacity. The listing for the 100D claims the vehicle has a range of 381 miles or 613 kilometers. The motor output is reported as 90 kilowatts (121 horsepower), which is the maximum output the Tesla motors can sustain without overheating. Autoblog notes that EU range estimates tend to be more optimistic than those issued by the U.S. EPA. A more realistic range might be 310 to 320 miles.

    Those mileage figures need to be taken with a huge pinch of salt. Based on my own experience with my 70D (my real world range estimate = 200 miles) I estimate a 100D would have a range of around 285 miles. Which is still excellent.

    I think 381 miles will only be possible driving 30mph on a flat road with no wind.

      With about 10% of the battery reserved, you have roughly 90kWH to play with. To get 380 miles of range, you'd need to use ~237 WH/mile. I've done that, but it's a pain. Basically constant speed without slowing down or speeding up at ~40 mph on a flat road.

      Still, lifetime averages seem to be around 315 WH/mile so 90kWH should result in about 285 miles before the car shuts down (without bricking).

      Tesla have a range calculator to show expected range based on speed, temperature, whether air con is on etc. Various factors will reduce your range from the optimum so you'll almost never get the full range quoted.

      With 90% of the battery available for use, and a typical usage of 180wh/km, you get close to 315 miles (500km).

      Real world numbers for the 100D should be between 450 and 500 km (280 - 315 miles).

    Batteries are generally extremely heavy in their weight to energy ratio compared to gasoline. They also cost a fair bit of money and take a while to charge if you manage to drain that huge of a battery. Even your regular 240v home outlet could take a while. At some point aside from bragging rights it becomes impractical to have a battery that big. The Volt only has about a 40 mile battery and I've made it through the entire summer without having to resort to gas on my daily trips. I've even forgotten to plug the thing in at times and it still had enough. Granted I live in a small city so that helps but I can't see what having past 200 miles gains for you. It might be a bit easier for cross-country trips if you're hopping supercharger stations but I have a bad feeling that you're paying a huge amount in extra weight and costs for that minuscule usage situation. (Unless driving hundreds of miles a day is normal for you.)

      For me, I don't have a charger at home (live in a condo with garage parking). I charge at work. So having the extra range means I don't need to fight for chargers as often. Right now, with a 85kWH battery, I find myself charging about twice a week (including the weekend trips) at work. If I can knock that down to once a week, it'd make a big difference to me.

      In dense urban places, that kind of mentality is probably pretty common.

      The other benefit of a bigger battery is that superchargers will give you more range before going into the trickle-charge range. That should make refueling on a road trip faster.

      Unfortunately not everyone is as luck as you with their commute, and some people do things on the weekend. 40 mile range is laughable. If it didn't also have gas engine it would sell as well as electric bikes...

      What would be cool, is a quick way to add batteries. 150 mile standard, and add/remove battery where you can add multiple 25lb batteries under the back seat to get up to 300.

      300, which isn't high(comparing to gas) is respectable and 20 min charge times are not much longer than normal fueling.

      Could you knock it down, though? How much amperage can your employer's chargers deliver? Most of them are limited to 30A, which means it's going to take better than 12 hours to get 80 kWh on board. If they support the J1772-2009 80A mode then your car can take 72A (17.2 kW) and you can get a full charge in 4-5 hours. Otherwise, you may have to plug in twice per week just because you can't get enough during a single session.

    I think people who actually need to tow things are the niche market since most people don't. Most people here go from home to work, home to drop the kids at school, home to the store etc and for that the range of the Tesla is good enough. On top of that, instead of 2-5 minutes filling up, you can fill up overnight or use one of the higher power chargers at the shopping mall (Several malls here in Montreal have them) and have a full charge when you are done shopping or eating. If you think about it, it's actually a more efficient use of your time since you no longer have to supervise the car while it charges. It's just a matter of not thinking of "refueling the car" as a separate task the way we do now. If we can get the low hanging fruit of small car needs, we will vastly reduce how much crap we put unto the air and reduce the money we are sending to crazy Monarchies in the middle east who then use a bunch of that money in ways that cause us trouble.

    1. A Tesla has more HP than a M3.
    2. The "refueling" happens in your home, while you get on with your life, rather than waiting in line at the gas station.

    "niche market" is kind of an overstatement. In fact, your usage scenario -- according to statistics -- is the "niche market". Very very few people actually need the ability to get into an 8000lb truck and drive 600+ miles before needing to refuel.

    Most people need to drive 5-40 miles twice a day with a ~8 hour gap in between. Hardly a "niche market".

    As for hauling and towing...it depends on your fleet size. Electric motors are actually far more ideal for the job of towing due to the flat torque curve. But if you're a one-truck-shop and can't swap trucks out to recharge (like larger businesses can) then ya, electric would be very impractical.

    I could totally see shipping trucks being an ideal situation for electric. Regular schedules, a lot of dead-time and regular routes where chargers could be installed.

    Realistically, gas cars *are* the niche market. The cost is what's keeping electric sales down. But battery cost/kWH is actually dropping quite a bit in recent years due to all the advances made for smartphones.

The only thing I notice about going up grades like that is the battery drains rather faster than normal. 120HP (90KW) for steady driving is a lot.

    Obviously bigger batteries are going to give you more range and possible better acceleration (at the risk of melting the motor).

    For that a Nissan Leaf will do, really. But how often do you do those not so everyday things? If it's one trip a year maybe, if it's ten trips a year I have to take out a lease, go collect the car, inspect it for any damage so they don't blame me, transfer all my belongings, deal with an all new car and once I'm done drop it off and get home I'm not going to do it. Actually a Tesla would be pretty sweet, but it's also a premium car. I can get a compact that serves my needs for half the price if all I need is the occasional range. Not to mention my Ford Focus can pull a trailer, no need for the Model X.

    Of course my gas engine car has a 55L tank and uses about 0.7L / 10km so it's 6-700 km between tanking with 100 km to spare. Also unlike an electric car it's not a big deal if I run close to empty, while being stuck at a charger when you don't want to sucks so I'd probably top off the EV all the time though I technically didn't need to. Maybe you can shave off a few seconds but you only need to screw up once because you were in a hurry or distracted or the charger malfunctioned and you could be stuck for half an hour or more.

    Here in Norway they've given huge incentives to EVs, built out a massive number of chargers but the sales peaked at about 15% and is now trending back towards 10% market share. And that's in a market where a Tesla P90D costs less than a Ford Mustang V8... okay so muscle cars are punished horribly. Anyway the Leaf has been doing well paired with a big "family car" as the commute car, but I think they have a long way to go to make any serious dent in the ICE market. Globally the need for cars probably grows faster than EVs can, so at best it's slowing a trend not turning it.
