EV adoption will need a new charging Industry

EV adoption will need a new charging Industry

So in an ideal world EV's will become a big part of the car market. As it is growing, one thing that will be needed is a mobile charging platform that can meet travellers on the road to top up their car or in the case of cars with zero range, charge them up. Like a tow truck or a road service like CAA in Canada. So to all you with the cash to start a new business, i invite you to get a flatbed or van and throw a generator, hopefully a gas fed one, onto your truck and start the first mobile charging platform road service. You can strap on a 100 kw or 50 kw unit, whatever you can afford and hook into the charger networks.
Its just what the range anxiety doctor ordered.

You snooze you loose.

Just sayin ......

Mobile chargers are already being used by some Autoclubs. They use them to get stranded EV's going again.
Ask. Dr. Google.

Cool. Thanks for that. The writing is on the wall.

I wonder if the new VIA motors hybrid pickup trucks could be used for mobile charging. They can do 240v at 50 kw.

I wonder if there any way to use large capacitors to dump a fast charge into a battery.

DTsea | July 22, 2014

Wrong model.

The truck will be expensive with batteries and will not be numerous. You have to wait for the battery truck and then you tie it up while you charge.

Much simpler and cheaper to just tow the car to the nearest charging station.

Actually, now that the Supercharger patents are open, someone could come up with a 5kWh capacitor pack that could be built into a tow truck. On the capacitor pack is a charging unit like at the Supercharger station. Plug the CapPack into the Model S, dump the full 5kWh into the car at 400 miles per hour (which would take less than 3 minutes) and the Model S owner now has enough range to travel for 15 miles and find a charger. Charging the CapPack itself could be done just as fast using a grid-tied charger at the towing garage.

When Tow Trucks finally go electric, you could even make the battery pack in the truck slow-charge the CapPack to keep it topped off, and ready to go.

DTsea | July 22, 2014

Or, you could just take the car to a charger. Seems easier... and any flatbed tow truck could do it.

DTsea | July 22, 2014

For this to work it would have to be CHEAPER to the consumer than a tow... but most people have tow coverage on insurance anyway so they are indifferent to price.

I've always considered the current situation where Tesla is manufacturing and installing high speed charging stations to be temporary. There are currently 120,000 gas stations in the US, and about 100 Superchargers. Until other companies get into the business of making and installing high speed chargers, the EV market won't be able to take off.

DTsea | July 22, 2014

apsley there also about 100 million homes in america. almost all have electricity.

"apsley there also about 100 million homes in america. almost all have electricity."

And mine is getting a 220 V circuit to power my MS through Tesla's HPWC.

DTsea | July 23, 2014

so I think electricity availability is about 3 orders of magnitude better than gas stations, in towns and cities where people live. The only places where it is sparse is along the highway away from towns. A few hundred superchargers should cover the bulk of that.

vgarbutt | July 24, 2014

I disagree with a tow being better than a charge. We can't assume for this exercise that the tows are free. I bet a via motors vtrux pickup mobile visit with an hour charge would be cheaper. It certainly would be more convenient and faster to give you the few extra miles needed to the next charger. They could charge by the km.

A flatbed truck will need to load, unload, take you off course, and cost by the Km , plus the charge. Tow trucks are expensive!

DTsea | July 24, 2014

insurance pays,

DTsea | July 24, 2014

tow charges are forvtime too. time with driver and truck will cost.

carlgo | July 24, 2014

Charges by the side of the road are dangerous and tie up the tow guy for a long time, per DTsea above.

But a tow to a charging station could be a very long way if the anti-Supercharging people have their way. 200 in this vast country...really now.

As with all things electric, got to have lots of fast charging facilities and have them everywhere.

100 million homes...sure. Just pull up to one and asks to plug in. Is that a Glock?

Al1 | July 24, 2014

Some buses are experimenting with charging within 5 to 10 minutes, while at bus stops. Wonder if at some point charging car would be similar to jump starting it, so that it could drive to the next station rather than towing it.

This bus is one of them. And actually there may be only two such bus companies

There is already charging infrastructure on the road. It needs to be modified and monetized for the BEVs:

1. Every trailer park has hi amp connections. They need to be enrolled and listed on the Tesla map in the auto. Pay per hour fee needs to be negotiated.
2. All Motels have 40-50A/240V circuits. They need to be signed up and listed on the map. Good advertising.
3. Gas stations? They could even provide 100A for a HPWC and charge $10/hour. Make money on all the junk food folks would buy!
4. MacD could easily install HPWCs and charge for them. Plus all the junk food you can eat sales!

I think all this will happen. Tesla is limited. Just deploying SCs is taking a long time.

@Bubba2000 | JULY 25, 2014:

"There is already charging infrastructure on the road. It needs to be modified and monetized for the BEVs"

The best available charger besides the SuperCharger is the Tesla HPWC. At best, it can deliver about 58 miles of rated range in a 1-hour charging time. Are you suggesting that many Tesla owners would be happy stopping for an hour for each 58 miles they drive?

Just deploying SCs is taking a long time."

My crystal ball tells me that Tesla has just begun deploying SCs. To support Tesla's growth plans, I think thousands of them will be needed within 10 years. Yes, I mean well more than 1000 in the United States. It's really simple: When you increase the number of Teslas sold by a factor of 10, you should expect about 10 times as much demand for SC charging. Because of economies of scale, that will not require 10 times as many SCs. I expect it to lead to at 7-8 times as many SCs.

Such growth in SCs needed isn't cause for alarm. The money to pay for it in a sustainable way will be available with no more than minor tinkering with the SC-enabled feature of new Tesla cars. And of course, just imagine range anxiety disappearing from the Tesla forums as SCs appear in abundance on virtually all of the interstate highway system.

Go Tesla!

vgarbutt | July 25, 2014

i guestimated about 600 on the main roadways and then the cities and town and hamlets etc. Lots of four corner chargers. Spaced at 100 miles, a car is never more than 50 miles down the road either way.

I calculated by the road mile, not by the range circle as Cars can't fly.

In the cities you can use range circles, but they would be maybe on a 20 block grid perhaps, or as makes sense for the purpose and location.

Bubba2000 | July 25, 2014


The effective range of 85 KW MS is about 230 miles at 60 mph. The 40-80A helps in an emergency if there is a miscalculation on range. Yes, we need at least 500 SC sites in the US.

SamO | July 25, 2014

Tesla could pepper 10,000 HPWCs in hotels, malls and monuments throughout the US.

Cost for hardware $1200

Cost for installation $400

$1600 x 10,000 = $16,000,000

1000 Superchargers x 150,000 = $150,000,000

The US would be ready for M3

vgarbutt | July 25, 2014

I wonder if tesla will do any lower power level chargers and place them like mentioned above, or will only build the style they build them now. Its an interesting question as to how Tesla will treat the more densely populated urban charging demand. I guess we will see in 3 - 5 years.
