Can the electric car industry bring this ghost town back to life?
... Cobalt.ca, population 1,100, is poised to flourish once more due to its
rich stores of the metal cobalt. Ironically, the town known for its silver
was actually named for this shiny, bluish-gray ore. At the time it was
mostly ignored. But not anymore ... this versatile metal is used in magnets,
in alloys to make jet turbines, and ... demand for cobalt greater right now
than from the renewable energy and tech sectors for use in lithium-ion
batteries ...

The company has confirmed the debut will take place next month at the 2018 Consumer Electronics Show [ https://www.ces.tech/ ]. Called the Genovation Extreme Electric (GXE), the car in prototype form hit a top speed of 209 mph during testing back in February [ https://www.motorauthority.com/news/1109077_electric-corvette-reaches-209-mph-sets-new-standing-mile-speed-record ]. It also hit a standing mile record speed for electric cars of 190.4 mph. While the prototype was based on a C6 Corvette Z06, the production GXE will actually use C7 Corvette Grand Sport as its donor. The car will also feature some unique visual treatments to ensure it stands out. You’ll notice the revised front bumper and round taillights. Genovation says it chose the Corvette as the donor due to the lightweight frame but also as a nod to American engineering. The company plans to build just 75 GXEs in total, each priced from $750,000. That’s certainly steep but if you want similar performance from an electric car you’re going to have to step up to the million-dollar-plus Rimac Concept_One. Power in the GXE comes from two electric motors delivering a peak 800 horsepower and 700 pound-feet of torque. The motors are positioned at either end of the car to create a 50:50 weight distribution, and uniquely they send their drive to the rear wheels only. Yes, they power a common shaft. Also unique as far as electric cars are concerned is the availability of 7-speed manual transmission. An automatic is standard. Performance claims for the GXE include a 0-60 mph time of less than 3.0 seconds and a top speed of over 220 mph. Genovation isn’t providing details on the battery though we know it will have a 60-kilowatt-hour capacity. We also know the car will be fitted with carbon fiber wheels. Genovation plans to start deliveries of the GXE in 2019. With the money raised, the company plans to develop a more affordable electric sports car dubbed the G2.

Electric cars in rural America
December 31, 2017 DENVER — Urban centers across the country are
experiencing strong growth in electric vehicles, driven by high customer
satisfaction and financial subsidies. However, the same level of interest
has not translated to rural America ... Until electric vehicles can travel a
minimum of 200 miles on a single charge and are priced similar to internal
combustion engine vehicles, adoption in rural communities will likely remain
muted ...

[EVDL] EVLN: Bolt makes you feel like an EV driver for life
https://cleantechnica.com/2018/01/01/my-year-of-living-electrically/ My Year of Living Electrically (Chevy Bolt Review) January 1st, 2018 Mitch Stone [image https://c1cleantechnicacom-wpengine.netdna-ssl.com/files/2018/01/Chevy-Bolt-one-year-review-768x576.jpeg (Stone's bolt) ] The afternoon of December 30, 2016, was a rainy one in Southern California. I remember when we used to have those. It was also the day I drove a Bolt EV off the lot of my local Chevrolet dealership. It was the very first one they sold. This week marks an elapsed year after taking this plunge. Anniversaries can be arbitrary and forgettable dates, unless you are married. Yet a full year seems as good a time as any to pause for a bit of reflection, to ask myself how this purchase has worked out. My driving case isn’t typical. I work at home and don’t otherwise place heavy demands on a car, so the 6,400 miles I’ve put on the odometer during the past year is less than many drive their cars in just a few months. What I’ve found to be more unusual, though, is that I am otherwise in Chevrolet’s target market. That is, I was a first-time EV buyer. My unscientific conclusion based on conversations with other Bolt owners over the last year is that a large number (if not a majority) of Bolt buyers in its first model year were previous EV owners who already knew their way around this type of car. They were drumming their steering wheels impatiently waiting for a reasonably priced EV with a useful range. I had no such basis for comparison. I was ready for the technology, but my criteria were entirely about whether the car would meet my daily driving needs without disruptions. Mainly, I was seeking a smooth transition from hydrocarbons to electrons. The purchase itself was a total leap of faith. When I placed the order over a year ago, few outside of auto enthusiast magazines had even set eyes on the car. This is not normally how I buy cars, an event that comes up about once a decade. I buy to keep, so I try to find a way to rent my keeper beforehand. That wasn’t an option with the Bolt. I’d also never owned a GM product, so this too created some anxiety. I would have to base my decision on nothing more than reading, and a test drive when the car arrived at the dealership. Fortunately, it was generous. The sales staff was equally curious about the car. I took a deep breath, and wrote the check. We have another car in our household well-suited for long trips, so I decided from the outset to not push the Bolt until I felt totally comfortable making round trips well within its rated range. While I can certainly admire those brave EV warriors who plan long cross-countries in their Bolts, folding in all those charging stops, that isn’t me, at least not yet. A year in, and I still haven’t charged the car outside of my own garage. And to be honest, I am astounded by the stories I hear from owners who drive their Bolts down to the electron equivalent of fumes. That isn’t me, either. I don’t need the stress, unplanned hunts for chargers, or any related freak-outs coming from the passenger seat. They would definitely violate my smooth transition directive. As planned, I’ve stepped out gradually. After completing my first drive to Dodger Stadium in the spring (around 130 miles from home, roundtrip), I felt a bit like Lindbergh landing in Paris. If the EV veterans out there are laughing right now, I understand. The point is, for an EV noob, the first drive of any real length without a petroleum safety net is a genuine adventure. I made that trip many more times during the year, each more routine than the one before. On picking up friends on the way to a ballgame in midsummer, I received a polite inquiry: could the car really make it there and back? Being able to answer “yes” with total confidence was no small thing. Longer trips are coming, I have little doubt, but only because these intermediate drives were so informative. I won’t tick down the list of the car’s quirks. Every car has them — the Bolt perhaps a few more than most. Chevy made a compromise here or there that we all wish they would have avoided. They are already much discussed and debated. Suffice to say, I can live with them. The anniversary question is whether my gamble on the Bolt paid off. I’d like to think it has, for both me and Chevy. Overall, I’ve been successfully introduced to EVs. And while my comfort level has grown, I still feel like I am driving the future. Electric motor propulsion is so clearly superior, I cannot imagine going back to the old way, which now feels primitive, like banging rocks together. If selling that concept to people like me was the plan, then Chevy hit the target, with bonus points. With each passing day, I picture myself less like an explorer hacking his way through the jungle looking for civilization. I feel like I’ve already found it. I feel like an EV driver for life.

Re: [EVDL] Good News: EVs Are Not Crashing the Grid
I agree with Tom. As EV are slowly adopted, the grid will find ways to adapt. Always will and always has. My state electric utility has asked customers to volunteer (with a nice cash incentive) to put "black boxes" on their air conditioning loads and electric water heaters. The boxes turn off these loads, under the command of the utility, for a few minutes during peak load periods. With the thermal inertia, you never notice your A/C was off for a few extra minutes. Shaves the tops right off the peak loads on the grid quite nicely. Little black boxes under remote control are the cheap solution. Everyone wins. I would imagine that when EV charging loads become significant, they will do the same thing. It would be stupid not to. Only makes sense. Costs very little and you leave the grid pretty much the same. Utilities love it. You sell more kWhrs using the identical generation and distribution equipment. No upgrades whatsoever. Only folks that volunteer have to do it, and save a bit of money. Everyone wins. Simple simple. What's not to like? The "grid overload" is simply a scare tactic campaign paid for by folks that will stand to lose by adoption of EVs. (Koch brothers?) Bill D. On 1/1/2018 8:33 PM, Thos True via EV wrote: Peri & All, I recall addressing this fear about a decade ago when it the fear was being pushed by mainstream media. The reality is no different than events that have occurred many times since the inception of the electrical grid. It is interesting that the utilities seem to do their best to avoid this conversation. Some that we might recall were the fears about every house having a refrigerator and washing machine, then it was the clothes dryer, followed by microwave ovens & hand held appliances and the hot tub craze, followed by the air conditioner installations. The air conditioners do have a noticeable effect on the grid due to a few factors (1. Grid already stressed due to over heating. 2. Large numbers in a region using the device at the same time (large, continuous inrush currents). 3. Extended periods of load for each device (in excess of 4 hours each).) The previous example share the relatively short, staggered inrush current events, followed by lower power demands, which are barely noticeable, according to the utilities themselves, since most L2 units use the same amount of power per use as the average clothes dryer.

An ammeter and digital thermostat proved it- I would pull 100 amps continuous with peaks to 300 amps going up our big hill. You would think the motor would stay cool in -10 and the occasional snow pile hitting it when backing up but the temps would hit over 120c on the case before I started actively cooling it. As well, without active cooling those temps would remain high for 2+ hours with the cart shut down. Smooth, sealed iron bodied motors that are tucked up under the seat don't get much cooling. If you are rolling down streets without big hills there should be enough time between loading to dissipate some heat but understand the heat takes a long to time to fade. High gearing and extra passengers will increase those temps. > > You might also try Bob Rice's solution. He used *two* golf cart motors, > one per wheel.

Yes, that's what I did for my very first EV. It was a 1974 Datsun pickup, with 72v of golf cart batteries in the bed, and a surplus 30v 500a aircraft generator for a motor. This is in effect a sepex motor. My homemade controller used a big rheostat to control the field current. It was connected to the accelerator pedal. The armature was powered by a contactor controller, which could apply 36v or 72, with or without a series starting resistor. It's important to wire it so you can't apply power to the armature unless there is field current. In my case, I had a relay coil in series with the field that had to be pulled in to enable power for the armature controller's contactors. If I dig around a bit, I can probably find my old controller schematic. It was a very drive-able setup. Good speed control, smooth accelleration, and very strong regenerative braking. However, it was quite unlike any normal car's throttle response. The accellerator pedal behaved more like a cruise control; moving it caused the motor to try very hard to move to the new speed. In particular, removing your foot from the accellerator pedal commanded *full regen*, which would lock the tires on anything but dry pavement. -- Whether we or our politicians know it or not, Nature is party to all our deals and decisions, and she has more votes, a longer memory, and a sterner sense of justice than we do. -- Wendell Berry -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

That does sound challenging. I wonder if it might be easier to build the trailer so you back the Bolt into it with its rear wheels inside the trailer (not on the ground). Then lock the Car in place. Remove the back tires from the car for ground clearance, and so it still sits level to have proper front wheel alignment. Now you have a 4-wheel motor home. :-) Still a lot of work. I've thought about this sort of thing, too. I think a better approach would be the one that Dave Peterson used to build the Ultravan motor home. He was an aircraft designer, so he built his motor home out of sheet aluminum, riveted together. It looked like the fuselage of an airplane; very light and streamlined. Then he removed the drive train from a Chevy Corvair, and mounted them in the Ultravan. The end result was an aerodynamic 22' motor home that weighed about the same and got the same gas mileage as the Corvair donor car. http://www.corvair.org/chapters/ultravan/ Do the same sort of thing, but use a Bolt or your favorite car as a donor. -- Whether we or our politicians know it or not, Nature is party to all our deals and decisions, and she has more votes, a longer memory, and a sterner sense of justice than we do. -- Wendell Berry -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

Forget that solar trailer lunacy... what I want to build is an RV trailer for the BOLT. I want to add a complex sliding panel system to streamline the car with the trailer so that they become one for aerodynimics, but can make a reasonable turn and handle dips in the road too. By eliminating most of the aerodynamic trailer drag at the discontinuity between car and trailer and letting the end of the trailer end in a teardrop I think a very significant decrease in aerodynamic load can be achieved. I am sure that no one can build these commercially because there are surely all kinds of standards and requirements that simply do not allow it. But a home built can probably get away with it most of the time. Anyway, something to think about someday. bob WB4APR -- next part -- An HTML attachment was scrubbed...

A circuit diagram might be clearer, but hopefully words work OK: On my tractor: Keyswitch turns on field relay field relay hooks up field to a 12V battery The field lead is wrapped around a proximity reed switch (used in alarm systems to see if a door or window is closed, the switch changes state when a magnet gets close enough to it). The wraps of wire provide the "magnet" to close the reed switch. Current in the field closes the proximity reed switch The proximity reed switch turns on a contactor relay that feeds the armature through a big, high power current limiting resistor The proximity reed switch also feeds a delay relay After about 1 second the delay relay feeds a contactor that shorts the current limiting resistor Don't forget to put a big diode on the field, otherwise you'll get a big arc when you shut off. It is amazingly smooth, I can start in gear and the tractor takes off very smoothly. Idle RPM is about 3600 rpm. I get regen down hills. The tractor has a variable speed transmission so I don't need to change motor speed. If I did, I would put in a welder rheostat in series with the field. I also have a car with a sepex. It has a Kelly 144V sepex controller. The controller needs to have been ordered with the appropriate current range for your field. My first motor had low field resistance, the Kelly worked well for that. For my new higher resistance field motor, I can't get the Kelly field current to go low enough, so I have to run in "Voltage Mode" for the field, which means no field weakening. It still works pretty well, but that cuts off my higher RPM. If I could get to the field current sense resistor I could fool it to work at lower field current (it's potted, I'm reluctant to remove the potting compound).

Re: [EVDL] Hot rodding a SepEx golf cart motor
Hi Dan and All, Looked at EVDRive and interesting but I was trying to find a lower cost solution. Interesting a motor for the Spicer unit gets about 17% more speed so hopefully means a lower ratio. As for 6.7" lasting I've been abusing them for decades now and they take it well normally running at 2 x rated power even in Florida heat with a fan. I'm planning a very low drag EV, 60-80wthr/mile so even at 50mph if the gearing lets it should be a problem. I normally tow a 1k lb loaded trailer behind my EV trike pickup using the series version. And I already do use 14" LRR tires Are you sure your bolt pattern isn't 4"x4" instead? There are like 4 4 lug bolt patterns within 4mm of each other. Still need an answer on this if it'll work, First hitting the the power > supply/field full on and then the start solenoid with resistor inline, then > short out the > resistor and then reduce the field to increase speed.?

I have a couple 96 ezgos that I fixed one up for my pig. Originally one came with an aftermarket 36/48 Alltrax controller which was running at 36v. I replaced the dead batteries with a 48v pack, motor had no issues running at that voltage but the used controller failed within a couple months. I replaced it with an Alltrax series controller and D motor. Shunt controllers are usually more expensive then series controllers. The EZGO TXT I have has a Spicer diff as well, not sure of the exact ratios, you can get high speed gear sets but they are pricey IMO. The bolt pattern on my spicer axles is 4 x100 so larger rims from an ATV or Civic would also give you more distance per turn. Watch how much load you put on those sealed motors, most are Iron cased and dissipate heat poorly. I have a thermostat and fan on mine now.

Thank you @elonmusk and @Tesla for designing a well-built, safe vehicle. We
struck a good sized deer in our #Model3 at 45 mph and everyone was well
protected. The damage is illustrated below. We have full confidence in Model
3!
]
It might not be the first thing crossing your mind when you hear more and
more Model 3s are finding their way to their new owners and onto the roads,
but this also means the likelihood of Tesla's latest sedan being involved in
a crash is significantly increasing.
The crashworthiness of Tesla vehicles is notorious, with the Model X
recently becoming the safest SUV out there and the second safest vehicle
behind only the Model S, which means the Model 3 should also become the
leader in its segment. But until we get the official ratings from NHTSA,
IIHS or EuroNCAP, we have to rely on the misfortune of the early owners to
gauge just how sturdy the electric sedan is.
Apparently, with only a few hundreds of Model 3s on the roads, we already
have at least two incidents to base our preliminary conclusions on. The
first comes from "Model3guy" on Instagram who was kind enough to share his
experience despite the fact he risked getting lectured by those people who
always know better and who seem to own the Internet.
He doesn't go into too many details, but we think the pictures tell a
thousand words. We can see the road covered in fresh snow, the Model 3
wearing snow chains on its rear wheels alone and the front planted into the
rocks on the side. You don't have to be Sherlock Holmes to realize what went
on. A set of winter tires would have probably spared Model3guy from his
troubles, but you live, you learn. Talk about online guys who know
everything...
News of the second incident came via Twitter, but this one is a lot more
enigmatic. The claim is that the Model 3 hit a "good-sized" deer (whatever
that is) at 45 mph (72 km/h), and the user called "Happy Chair" also
included a picture of the aftermath. However, the car seems to be perfectly
intact, so unless he did it while reversing, we find it hard to believe that
it didn't leave a more pronounced mark.
Either the deer wasn't "good-sized" or the speed wasn't 45 mph, but
something most definitely has to give. Or maybe this was just a veiled hint
at the Model 3's duck-faced design that looks as though it's been involved
in a deer collision?

One of the many benefits of battery-powered cars is the incredible torque
and acceleration an electric motor can generate. It’s not just a feature
exclusive to Teslas; you can actually upgrade almost any electric vehicle
with equally ridiculous acceleration—even a mobility scooter.
There’s not a lot of details about how this upgrade was performed, but you
can assume that, in addition to a bigger battery and beefier motor, the
scooter’s structural integrity was (hopefully) strengthened so that it
doesn’t just disintegrate at its new top speed of around 62 MPH.
