People really need to get over the "range" of EVs. The average person drives about 35 miles per day, a low end EV has about 200 miles of range on a single charge with batteries only getting better. Further, the semi-truck and larger vehicles like buses have an advantage as EVs as you can put larger capacity batteries on them. This increases the range considerably on the larger vehicles with current technology and only gets better as batteries do.

In the future where solar technology is at an efficient enough point the larger EVs will simply have large solar surfaces to help charge the batteries during driving to extend range. You also have the enormous potential for the regenerative braking off a semi-truck. There is an incredible amount of energy to recapture and turn back into battery energy on a loaded semi-truck coming down a grade.

Although when you really look at it the truck driver is a dead species and will be out of business in 10 years at most. Trucking is going to be one of the first industries impacted by autonomous vehicles.

I want more info on that pickup truck. Finally, someone going to do a EV pickup truck.

Glad I wasn't the only one that got excited!

No kidding. I been waiting on a EV pickup or mid size truck since EV cars came about.
I don't mind cars, but I prefer pickups and trucks for the versatility they give.

Now, if they can get the range right and make a four dour with a decent bed length.

Hopefully on a proper chassis and not uni-body.

Would be a dream!

Although when you really look at it the truck driver is a dead species and will be out of business in 10 years at most. Trucking is going to be one of the first industries impacted by autonomous vehicles.

Here is the thing though - if we want to buzz down and visit the in-laws over the weekend (340Mi) we can, and we can on less than a tank of gas.(I realize this comment isn't necessarily "Semi" related but related nonetheless - even more so given the range Semi drivers have to go over the course of a day) Electric vehicles are awesome - but I certainly don't want to plan my day and my trip around the range. Might as well add a puppy to the family. tongue.gifthumb.gif With that "electric hate" said, I plan on getting a Zero motorcycle this summer for the 12 minute ride to work - should be nice not buying gas for a few months.

I don't even. wut

 

Average people don't drive semis. Argument does not apply. Range is everything in semis. Day truckers drive close to home but drive all day, and will go hundreds of miles in one shift. To have a battery that would last all day would be very heavy, further reducing range, etc. In a car, the aerodynamics draw far more fuel than the weight. But in a truck that weights 10-20 times that of a car, accelerating from stoplights takes a huge quantity of power. The size of battery in a delivery truck to last all day would make a uselessly small payload.

 

I'm not even going to begin on long haul truckers.

 

I challenge anyone who thinks this is the next sliced bread to watch any videos from truckers/people who use trucks on daily baseis (loggers, etc) online and look at the challenges they face on a daily basis. Not to mention all these concepts always have stupid plastic bodies that truckers don't want.

Now, if they can get the range right and make a four dour with a decent bed length.

The reference to a pickup also got my attention. If they can make a practical semi tractor, would they be able to make a crew cab pickup truck with 3/4 or 1 ton truck payload and cargo capacity and with decent range? Mayhap a hybrid?

The big rig tractors already have plastic (fiberglass) bodies to save weight.

The old gear jammers said the same thing when automatic trannies first came out. Now, most of the big rigs have full automatics because they get better fuel mileage and actually need less maintenance, especially with newer drivers (how many of you can double clutch and shift a crash box without grinding the gears or keep up with a main box and a brownie without missing the shift? Of course, if you are really good, you don't even need the clutch.). And I have talked to semi drivers (and even drove a few semis around for loading and unloading).

Of course, if you are really good, you don't even need the clutch.). And I have talked to semi drivers (and even drove a few semis around for loading and unloading).

On flat roads? Yes. Steep hills, particularly in bad weather? I want manual control.

In most cases it isn't up to the driver but up to the company they drive for. The company will use whichever option is going to net them the highest return.

People really need to get over the "range" of EVs. The average person drives about 35 miles per day, a low end EV has about 200 miles of range on a single charge with batteries only getting better. Further, the semi-truck and larger vehicles like buses have an advantage as EVs as you can put larger capacity batteries on them. This increases the range considerably on the larger vehicles with current technology and only gets better as batteries do.

In the future where solar technology is at an efficient enough point the larger EVs will simply have large solar surfaces to help charge the batteries during driving to extend range. You also have the enormous potential for the regenerative braking off a semi-truck. There is an incredible amount of energy to recapture and turn back into battery energy on a loaded semi-truck coming down a grade.

Although when you really look at it the truck driver is a dead species and will be out of business in 10 years at most. Trucking is going to be one of the first industries impacted by autonomous vehicles.

I want more info on that pickup truck. Finally, someone going to do a EV pickup truck.

Glad I wasn't the only one that got excited!

According to my back of the hand math, you could maybe get 13hp off the entire top surface area of a semi in direct sun.

In reality it's gonna be much less than that. That's enough to help, but it's barely enough to make up for the extra weight, not to mention the cost... There's a reason those solar racer cars you see are slow as heck even though they look like they're made of tin foil.



If you're talking about a 100% efficient solar panel, that's still under 50HP in really good conditions.
