General Motors has announced that the Hummer electric pickup truck will have several motor options (single, double and tri) and that range and price will vary.
Yes, most are direct drive or have a planetary gear. Folks who DIY convert ICE cars to EV do so by retaining the transmission. Miatas are popular and there are small AC and DC motors that work well with the five speed manual transmission. Apparently torque converter automatic transmissions drain too much power with their pumps (usually driven by a small eldctric motor since EVs don't idle) and prove to be unpopular for swaps. Pretty much every automotive automatic transmission type I can think of requires lots of hydraulic pressure, so maybe a new type of transmission will emerge. I just don't see EVs of the future wasting energy on idling or maintaining transmission hydraulic pressure.Since you can gear for torque, I imagine more pedestrian versions will eventually be available that will still move the loads without the headlines... at reduced speed. I think most of the EVs are direct drive? Maybe transmissions are coming to an EV near you.
Maybe the range is a legit issue for your fleet, which is surprising to hear, but I guess it’s possible. But plugging in overnight? Why is that an issue? Either do it at your depot, or credit your employees per kWh for plugging in at home, the same as my company credits me for miles I put on my personal vehicle. Not exactly an insurmountable obstacle.Gas vehicles won't be leaving my driveway anytime soon either.
I find them interesting, and from the viewpoint of a fleet, maintenance is appealing. Its the range and charging that are the issue. Mostly the charging, because if they could refuel quickly and easily range would be les of an issue. I'm not going to have an employee plug it into their house at night, and it takes too long to charge them at a grocery store.
Today, yes. But I fully anticipate cities and towns to take advantage of this cash cow. As soon as we reach critical mass of EVs, you’d better believe they’ll be installing receptacles with credit card readers on every lamp post and other existing electrical supply with sufficient capacity. Look at the way some cities aggressively chase the apparent pennies an individual parking meter brings, there’s an economy of scale at work, there.It would be a greater obstacle for those who live in a city and park on the road. Sometimes you don't even park in front of your house.
I've been reading that hydrogen is the future.Nikola announced their offering, to be shown in fall 2020 - The Badger. It touts 600 mile range via 300 mile battery range and 300 mile on a 120 kW hydrogen fuel cell. Having this whopper generator on board also has some nice jobsite benefits like a 15kW inverter.
The DOE just invested some $60 mil for researching hydrogen production from PV supplied electricity. It's an exciting time to be alive. I'm hopeful for hydrogen based liquid fuels to keep the majority of the current infrastructure in place.Eventually, I think it will play a much larger role in our lives, but I suspect not without a lot of resistance from the fossil fuel industry.
