Yeah, that makes sense. It could charge my cell phone faster! Having it engage the brakes equivalently is probably not a good idea? Seems fraught with edge cases.

Having it engage the brakes equivalently is probably exactly what you want, in fact, because then the amount of deceleration you can expect for a given pedal input is constant. Doesn't matter if the battery is full or empty, if you put your foot down X amount the car will slow down at Y rate, and the computer figures out how to balance the two systems. I know that people like to game the regenerative systems in their electric vehicles but really that should just be left up to the car. Also, if you tried to burn up the energy charging your cell phone it would have no effect on your car's speed and the cell phone would explode. A high-speed cell phone charger puts out around 10 watts, while I'd guess based on the numbers that a Tesla can regenerate at around 50,000 watts.

Yeah, but then the brake pedal is in a different position depending on battery capacity. Or they decouple pedal position, but they've been careful to not do that with autopilot. The regen goes to about 50kW, yeah.

Not often at all - However much energy you're trying to put into the battery, you would have to have removed more energy getting up to speed. The only exceptions would be either driving a long way downhill right after charging, or one of those fancy future roads that charges your battery as you drive.

If you live on top of a hill and charge to 100% you get it every morning. A good tip for reduced regen, if it's a pain to get used to or not, is to put some heat cycles and wear into your brakes which normally have very little asked of them. Many early Teslas over here have had problems with brakes not working or brakes being stuck in the cold.

^- Imagine four electric vehicles on the top of a hill... I wish there was some way to customize the pedestrian warning sound in my car (I just discovered it had that when running in pure EV mode). I dunno maybe it could play something else. Like songs from "Erasure". So it crawls by and they hear "...we're gonna be WE'RE GONNA BE TOGETHER AGAIN, I'VE been connected to the right line..." as it drives past.

I haven't really been into customizing since Winamp skinning days, but I think if EVs are required to have sound, it should be possible to change them around. Make/share/download stuff, change it on the fly while driving. Something like this to start with: https://www.youtube.com/watch?v=VA7145CNK_I Then maybe some seasonal vibe: https://www.youtube.com/watch?v=Axkte_QvgFU Trolling children: https://www.youtube.com/watch?v=_fprmKneQKs Trolling everyone: https://www.youtube.com/watch?v=8FjywBCv_8E And of course... https://www.youtube.com/watch?v=zPf_PJlJsJQ

One thing that bothers me about the car I got - the high voltage cables to the inverter package are pretty well protected - they've got a big orange outer sheath. However there are also wiring bundles that I assume go from the car's computer and other systems to the inverter that are in a bundle, but then the wires in that bundle break out into rather dinky little individual cables that plug into the inverter assembly. It just seems like a really cheesy thing to do, and I'm interested in maybe putting some kind of protective sheath over where the cables terminate - just to offer a little more protection from dust and dirt. Just had to get that off my chest.

Been mulling it over for awhile now.. But as of yesterday I am now a Volt owner... Bought a 2017 LT in Black, with cloth heated seats (I HATE leather seats with a passion, I don't see why people consider it an upgrade!) Haven't got to drive it much just yet... but this is the first electric drive vehicle I've ever driven. The near instant torque is awesome. Compared to my old 4-cyl 2011 Fusion, the Volt is a performance car. Some notes:

Jesus christ, I need to stop trying to pick people up from the airport in my Leaf. It's 70km each way, but there's L2 charging at the airport. First attempt, I had trouble finding the charging stations and only got ~10 minutes of charging, claiming ~50% charge and 80km on the rangemeter. The leaf turtled a few blocks away from home and I was able to get it within half a block before the battery died and then push it the rest of the way. This time, I knew where the stations were, and it took my GF about an hour to get through customs and baggage recovery, so it got nearly a full hour of charging. The trip there used just over 50% of the battery, and it was at 66% and 115km on the rangemeter when we left the airport, with one passenger and two weeks of luggage instead of two passengers and six weeks...and it turtled 20km away from home.  It's sitting in the parking lot at the vet now and I'll be calling a tow for it in the morning.

Nissan will tow it to the nearest public charger for free (the L2 at the nearby mall), or to anywhere else I want (e.g. my house) if I pay the difference (about 5km). It's 24/7 service but takes up to an hour for them to get there, and I wanted to get home and eat curry with my family more than I wanted to get the car home.

Why did you take the leaf when you know it doesn't have the range to do it without a recharge and without waiting for it to charge?

I was unbelievably stoked for the Model 3 (enough to go stand in line and give Elon $1,000 on day zero) but, man, I work from home and my 2011 Prius (with a hair less than 40k miles on it) has been paid off for years. I bought gas today and was curious when I filled up last, which was in early November. I've had this weird realization that I really just don't need a new car at all, even by 2018 when these things start becoming available. Is this what it's like being an adult? It feels weird and foreign.

I just don't have the disposable income to justify paying $35,000 before incentives for anything except possibly a house. I need that money to grow for retirement. It makes me sad because I think the Model 3 will be great, I just can't justify it and don't have a need for it. I hope it will still accelerate the future of cars, and maybe I'll buy a used one someday in the far future.

An electric car would be cool, but every time I hear coworkers talk about how little they spend on gas for their Models S, it inevitably segues to chargers and range planning, and I think about the delta between my car plus the $5k of gas I've bought for it, and how that doesn't come to a third of what their cars cost.

Not right now, but the I have sparked the owners interest in EVs.. Even saw him looking at Tesla. At the very least I might end up with an outlet to plug into! I have slightly irregular driving habits. I generally drive about 15 miles a day. Unless I have to travel to one of our branches, which are on average about 20-30 miles from our corp office. If I do have to drive to other branches, it tends to be in spurts for a few days at a time, and then not for several weeks/months. Since I use my personal vehicle for occasional work use I get a monthly allowance that covers a significant portion of the monthly payment, and then a company fuel card. Because of the work allowance I basically pay the same as if I had leased the Volt, if not a touch cheaper. Call me stupid but I actually prefer driving my own vehicle for work purposes. Edit: also wanted to add I have cheap electric. 9 cents/kWh for the first 300kWh, 5 cents for the next 700kWh, and then 4 cents for every kWh past 1000. I average about 800kWh (fully electric house) stevewm fucked around with this message at 05:57 on Dec 28, 2016 |

The current supercharger stations have about 100 panels on them, and even with their latest SolarCity panels that produce 350W, that's "only" 35kw of panels. They'd need 10x the rooftop space to get 350kw of panels, so it's gotta be the peak charging output.
