    miles due to regeneration

    There is no exception. Newton's First Law still applies. Regenerative braking is still an external force that acts upon a body in motion. It just wastes less (net) energy than friction brakes do.

    miles due to regeneration

    Not so absurd, especially if you live somewhere that goes down to -30C in January. :)

    miles due to regeneration

    Sean's example is correct. Let's say the car that coasted to a stop went 1500 feet. The car that braked with regen goes 200 feet. It's all fine & good that some energy was recovered, but you'd then be spending all of it + more to go the extra 1300 feet to reach the car that coasted. This is...

    miles due to regeneration

    Not exactly. The motor is >90% efficient, however the battery-to-wheel conversion efficiency is typically only up to 80% efficient. The energy makes a full circle back into the battery and it gets converted twice for a net efficiency of at most 80% * 80% = 64%. Keep in mind those numbers are...

    miles due to regeneration

    To add to Michael's point...preserving momentum is the key to efficient driving for any vehicle. Braking (regenerative or otherwise) kills momentum. Please post your source about regenerative braking recovering 80% of kinetic energy back into the battery. I don't know what the exact number...

    Transmission leak?

    Do you own the car or lease it? Own: Give them a reasonable amount of time to fix it (I'd say 1-2 weeks) . If that doesn't happen, make an attempt at lemon law. Lease: Let the next owner worry about it...that is, if there really is something to worry about.

    YMMV

    I doubt it's the only factor. From what I've read from his other posts, he loves to drive 80+ mph, and has hit the Bolt's speed limiter on occasion. In keeping with the YMMV topic, while it's possible to get 400 miles driving at 26 mph, I'm not sure it's possible to achieve 120 miles at 90...

    New Bolt owner, with some questions.

    Yeah, that's a bad idea. It's a driver's aid, not a substitute for safe driving practices. Pg 227 of the manual: LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all...

    YMMV

    You are correct, my bad.

    YMMV

    I think your math is a little off. The guy in the video drove 387 miles on 57 kWh...at 26 mph. That yielded about 6.8 miles / kWh. Driving at 35 mph introduces some drag into the equation, so your suggested speed will be less efficient, not more. I'm guessing that extra 9 mph would reduce...

    miles due to regeneration

    From the information display, we know how much power is being consumed from HVAC and other accessories. Does that same display show how much energy is being recovered through regenerative braking? If not, the OP said he'd be hooking up an OBD2 reader to find out. Would be nice to know.

    Hello from ChargePoint!

    Of course you're right, and I thought about that too, but it still costs money to feed the red tape. Governments find ways to make things that are free & simple - expensive & complex. It's what they do. At least for now, L2 in our city needs to be free. Installing 100 free L2 charging...

    Hello from ChargePoint!

    I'd argue not so simple. Then you need to set up a meter, charge cards, and a department that manages it. What the Councillor (and most people that oppose free charging) don't really comprehend is how cheap electricity really is in our city, and how few people (at least initially) will...

    Hello from ChargePoint!

    My first thought was something along those lines, but the high road is usually the one best traveled. There wasn't much chance of changing the guy's perception about EV's in five seconds or less. His day was already ruined, and I didn't want to make it worse. To be fair, I've also plugged in...

    YMMV

    My previous personal best on 25 kWh's was 114 miles - about 4.6 miles/kWh. The biggest "aha" moment I've had with my EV is understanding how little energy is recovered from regenerative braking, and why it should be just referred to as "braking". I used to think I could keep the needle between...

    Hello from ChargePoint!

    I'm interested, but more about understanding how the business model works, and if there actually are DC fast charging stations that pay for themselves from charging revenue alone. For me, I live in a province with over 4 million people, but with only a handful of EVs on our roads. This is Ford...

    Hello from ChargePoint!

    I can get behind the green and customer service angles...offering the chargers to attract revenue to your core business, as a great benefit for your employees, and my business being the good corporate citizen. However, In terms of ROI, we can be sure there is a lot more moving parts to this...

    Doug Score Review = 59/100

    On the contrary, I find Doug's reviews quite entertaining, mostly because he tends to review unusual cars (Lexus LFA, Ford GT, Mercedes R63 AMG, Hummer H2, etc.), and finds interesting quirks about them that I never knew, or that other reviewers missed. I think his "Doug Score" is mostly...

    EVgo DC chargers were horrible up until the beginning of 2018. They're still not perfect, but improvement is being made.

    Gravy...because the car has already paid for itself in fuel & maintenance savings? How many miles are on your Leaf? It's my plan that when I eventually sell my B250e, whatever I receive is "gravy" too - however I think I need to turn ~100K miles on the car before that happens.

    YMMV

    Extrapolating a result from the guess-o-meter leaves a lot to be desired. The only way to really know your maximum range / personal best is to drive it. For all the hypermiling rookies hoping to impress others with their skills, here's a number to shoot for: 387 miles on a single charge...
