I do not think the vehicles were driven at 45-50mph. The article says the test mimicked city driving, stop-and-go, which to me means 20-30 mph average. Plus I never get 105 miles range driving 50mph, at any temperature. Do you? I run about 225 Wh/mi in ideal temps driving 50, for maybe 90 miles...

I only noticed this happen yesterday, coincidentally. In my case it had to do with HD FM, I believe. I have a preset station that's HD, and I drove out of the range of good signal. While driving the station automatically switched to nondigital, but after a stop when I turned the car back on the...

I remember someone posting about this issue, last winter I believe. I could not find the post searching back; maybe it was posted in myfordmobile? Anyway, if memory serves, the person's heater element was replaced. I am under the impression that the battery heating hardware is separate from the...

You are correct that any vehicle with a plug has as much 'right' as any other. As far as etiquette/courtesy/whatever, the big picture is that prime chargers are a limited resource. The courteous thing to do with a limited resource is only take what you need, then move along to let the next...

I thought L1 was a bit less efficient than L2 but this is the first I've heard it quantified. Do you have a reference? 90% doesnt seem right. When I use chargepoint L2s where I can compare what i'm buying to what my battery's storing, I see more like 80-85%. I got 80% (actually 81% but I...

You're in the ballpark. Yes, about 19.5-20 kWh are available when the car battery is brand new. However not all the electricity your EVSE sends to the car ends up in the battery. Charging today's EVs is estimated to be 80% efficient. So you're probably buying more like 19.5/0.8 = 24.375 kWh to...

Wattsup- That graph you linked is nice and simple. It shows hyperbolic curves for different powered motors, all rising sharply at low loads, then leveling out at their respective max capacity over the rest of the load range. The curve for 100 hp approaches max efficiency at like 30% load...

In my area, unplugging someone is a bit trickier because for four to six cold months a year, that fully charged car is still using the plug to keep the battery warm and/or preheat the cabin. If it's my FFE, preheating can save me from more than 20 miles range loss on a full battery, so it's not...

It is more efficient but much less fun to accelerate as gradually as traffic allows. Similarly more efficient to start slowing earlier than you might in an ice car and decelerate as gradually as possible.

I haven't heard sounds exactly like you describe. At air temps between about 20 and 80 F, charging my FFE is pretty silent. At temps below 20, there's a kind of low volume whine. At temps over 80 or so, it makes a hum sort of sound I think (it's been 6 months since I've experiences those temps...

I think Tesla skipped Chicago this year.

Yeah richmond I had a similar response to the article. It almost seemed like a spoof comparison. I think the target audience was motorheads who want to get a good laugh at how limited these things are rather than people actually interested in an EV. I don't think it means much that the FFE was...

Probably an issue with your charger or its circuit. Are you using a level 2 or the trickle? I received that message a few times when I was using the trickle and it tripped my breaker... led me to realize some genius wired my garage outlet on the same circuit that covers half my kitchen. And...

How much of your battery percentage is used up getting from the plaza to the house? How much in kWh? That has got to be a pretty big hill, no? The fact that driving slower makes no difference in range drop suggests way more energy is being put to vertical climb than to pushing through air...

This has gotten into a whole new topic so I'm running with it. As far as promoting charging stations, Tesla's in a completely different situation than Ford on this. One, Tesla only makes electrics so yeah they have to care about the charging options out there. Ford and others even Nissan see...

I would (and did) purchase too. I bought at full $41000 just before the first $2000 incentive came out (d'oh!), when no one had them on the lot so you pretty much had to ask for it to be ordered or traded, and pay what they asked. I qualified for full tax credit and took IL's $4000 rebate, for...

Anyone else get a freebie Powerstick from Ford? Had a Fedex package at my door yesterday, containing this combination 8GB memory stick/mobile phone back-up power source. The enclosed letter says "please accept the enclosed Powerstick USB recharger as a gift with our thanks for your purchase"...

Huh. When I do the same thing, my range remains whatever it was with the climate control off. If temperature setting wasn't initially at LO, the range drops with the touch of the first fan button, but when I turn knob down to LO, range comes back to the starting position. Is the climate fan...

Interesting, jmueller- I didn't realize you are seeing a drop in predicted range even when activating the climate control system at LO defrost, without the heater engaged. I thought you were seeing the trend in how much range drops with the heater activated. My range does not drop at all when I...

Who says the FFE battery is expected to last well over 300k miles before noticeable capacity loss? Of course I would love this to be the case, but it seems incredibly, unrealistically optimistic. FFE's warranty covers high voltage batteries and other "unique electric components" for 8 yrs/...
