Range externder

Range externder

I have been thinking bying a MS for professional use in Belgium.
The problem is that I need 2 cars. One for longer distances,
one for shorter.
The problem is always to find a FREE charging point on the road,
or i have to ask my client to use a 230V outlet to charge my car.
That is not very practical.
So if i fear to get out of power during my trip overday, I have to take a normal car and so I have emissions for all the day.
But if the MS could be equiped with a range extender, the emissions would be limited to the range extansion that day.
The range extender don't need much power. Just enough to continu to drive at 75mph (120km/h).
The gasoline tank can be limited in order to have to refill every 200 km.
It would give me more confidence and i don't need 2 cars.

I am running a sales office and our HQ are about 120 miles away, and I make this trip every 3-4 weeks.
According to the range calculator, I don't get back even with a full battery pack.
And in a few years, the capacity drops to 80% perhaps, so that is getting even trickier.

To my opinion, this is worth to investigate, and i strongly believe that ist would convince a lot of people.

Bets regards,
Johan V

240 miles in the 85 should be easy.

Range extension is not possible for a number of reasons.

>>>> 240 miles in the 85 should be easy. ???
not at a constant speed of 75 mph.
i checked with EV tripplaner
and then again, if i do a trip to see 3 customers, and there is a change and go urgently somewhere else, i'm stuck

>>>> Range extension is not possible for a number of reasons.
which are ?

Added weight would be the biggest, (both engine and gas), complexity reduced storage, weight distrobution etc...

You don't want a Tesla, there are other companies that make PHEV's Tesla makes all electric cars.

This is a problem we have in the USA as well. Many who buy EVs also have other cars in the family for longer trips. I doubt you will ever see a range extender of any kind out of Tesla except for a battery swap station (years away).

toby_wan_kenoby | September 19, 2013

wait and see where the super chargers will be located... see if that makes it work for you.

Also I am sure if you were to show up with a Tesla at your customers they would allow you to plug in.. especially after giving them a quick ride in the rocket.

I agree with you that there are some people that would like to see a Tesla with a range extender. What you forget is that the majority of people are buying the car because it DOES NOT HAVE ONE.

From Tesla's point of view, the choices:

(1) Give up on our goal of turing our back on gas forever. Install range extender, making our cars more complex (gas AND electric engines) by sometimes burning a fuel in limited supply which pollutes the air we all breath.

- or -

(2) Install a couple hundred supercharges on every continent.

They seem to have selected #2. But it will take (just) a couple years.

No way there will be an ICE range extender -Zero Emissions, Zero Compromises...

You need to figure out an other way to charge. Supercharger on the way out, or back? Aren't there any public charging outlets near your client's office where you can plug in? Or give them a bottle of whine every time you plug in to their 230 V? Or slow down from 75 to 70 mph? Maybe it's worth it to go 5 slower to just own one car?

It's probably too soon for you to get a Tesla.

Once the superchargers are available in Belgium, you should have no problems. In the meantime, I agree that you probably want two vehicles.

As for range extenders, I see it as the worst of both worlds. You get the noise, weight, vibrations, smell, tuneups, etc of a gas engine, plus the extra weight of batteries and space loss.

The future really belongs to all electric vehicles. Charging stations and battery life will improve in the future.

Why do you have to find a free charging option? Obviously free is better than not free, but if your other alternative is to take your gas-powered car, that isn't free to fill up. Take the Tesla, and even if you have to pay to charge, it will still be a fraction of what it would cost you to fill up in gas.

I think he meant "free" as in "available".

@jvp I have ordered my MS85 for the same purpose as you and I am also living in Belgium.
After quite a lot of calculating and thinking I just ordered the car. Take a look at all the charging points that are already available in Belgium. And there will be a lot more when you will get the car. Asking your clients or prospects to use their plug indeed will not be easy. But finding a parking spot in the neighbourhood at walking distance perhaps will be possible. I am planning to do some work at a charging point on my way back home. Work that I would do when I am at home anyway. Realistically this will not cost me much time because of the traffic jams that are todays reality. At home I will be using 380V 16A to charge the battery. This should be enough at least when I get an eight hour sleep. There is a very interesting study 'electrische auto's op 1' written by Accenture unfortunately only available in dutch, about the behaviour of the EV drivers before having the car, during the first six months of driving the EV and after six months. Amazing how the mind shifts. If this really works, I hope I can give you more feadback in December when hopefully the car is delivered. Regards, Herman

With free i ment "not in use by another EV"

In Belgium there are some charging points in the biggest cities.
Superchargers are for 2015 i suppose.
If the number of EV's and MS is goiing up the way Tesla would like,
they'd better hurry up with those charging points.

To Herman: Thank you for the tip about the article. I'll take a look.
And please let me know if your MS is delivered and share your experiences.

Best regards,

Why would you want him to inflict "a bottle of whine every time" on his clients? Most would prefer wine. ;P

You may find that in marginal cases, you can compromise on your speed and aggressive driving enough on the way there to leave plenty of range to get home. Gentle acceleration and slightly reduced speed pay off in miles of range.

patrickclaerhout | September 21, 2013

The only range extender I agree with is a Brompton-bike in the frunk. Drive your car to a charging point in the neighbourhood and take the bike for the last couple of kilometres. You save on a extra car and on the cost of a fitnesssubscription. After the long ride (even in a Tesla) your concentration will improve due to the short ride in the open air.

By the way, is there anyone who knows if a Brompton really fits in the frunk? I didn't received my Tesla yet, so I'm not sure my suggestion works in real life.

Trip between Sales Office and HQ should be no problem. Install a high capacity charger at HQ - staying for an hour or two should give you plenty to make it home, no matter how fast you drive.

Until there is a lot more charging infrastructure, there will still be a need for ICE. You can get an EV with ICE range extension, or have two vehicles. We have an MS and a Prius...and a Toyota minivan and Acura sedan.

I don't see the problem: I drive my Model S (P85) regulary in Germany and Switzerland on long Business trips. Once a week I drive Zurich - Munich - Zurich for example (640km/miles round trip) on a single day: Starting in Zurich in the morning I get to Munich within three hours, driving 75mph in Switzerland and about 95mph in Germany and usually have around 70km range left in Munich. I there charge at a public charing station (3 phase, 32A) and recharge within 3,5 hours to almost full. I drive back in the afternoon and never had a problem.

From my experience you can easily drive 800km in one day if you have access to 32A/3-Phase charging stations which are already quite common in Germany, The Nederlands, Austria and Switzerland. I bought me a 8m long Mode3 Cable so I can access the charger even if an ICE would block to space. Important: You need to access 3-phase power. 220V single phase will get you nowhere (translates to max 15km/h charge vs. 61km/h [16A] or 124km/h [32A]).

Regarding the degression of the battery: I have about 22.000km on the clock and have not seen ANY degration of range on the battery until now.

LarsT | September 21, 2013

Correction: Zurich - Munich -Zurich is 640 km = 400 miles.
