Test charging stop for large EV’s, busses, trucks, mohos.

I'm closing the myriad of EV threads. Please use this one instead.

As batteries improve I see the battery outlasting the vehicle. In the future we might by a glider and swap in our old battery and keep on driving. Or the battery will be used for utility or home storage of electricity for an additional decade or two.

That's a true statement Reisender concerning depreciation. But a 10 year old car still has value today and most Americans buy used cars, not new. Hopefully less maintenance on EVs will offset the battery replacement costs.

As far a lawyers specializing in trip and fall, black cords are not too visible especially at night. I already see heavy cords strung across walkways, yards, sidewalks ect. in my neighborhood. We Americans are a litigious society. Most people do not park cars in their garage as they are full of stuff unfortunately!

EVs are coming and as they do new issues will present themselves. These are a couple I see that I don't see talked about.

Luv reading the discussions on RV.net

One thing for sure there will be Lawyers specializing in "cord trip and fall injuries"

One question I never see brought up is longevity. Average US car on the road today is ~12 years old. Many cars in California and the west 20 years or more on the road with original drive train. Tesla batteries are guaranteed for 8 years retaining 75% of their charge range. I suspect a steep drop off after ~10 years regardless of miles driven. This could have a big impact on used EV prices.Probably battery replacement at that age and would offset today's cars maintenance somewhat.

Not sure of the average semi truck on the road age today. That would be good to know.

I'm serious about the Lawyers! Can you imagine a four car family with all electric cars with some parked on the street!

Just the opposite. Most degradation happens in the first year or two.

I can’t follow your lawyers thing. What are you talking about.

How large of a power grid will be needed to recharge 2 or 3 hundred trucks such as Amazon or UPS or even USPS overnight? What will it cost to get the power to the charging stations?
Lots of expensive problems to work out.

Overnight?? That’s easy. It’s the one or two hour fast charge that gets difficult. If Tesla can put in 100 stall 250 KW V3 Superchargers then 200 x 50 KW overnighters should be doable. Some on site storage would help. Tesla does that.

ALL transportation is 20% to 30% increase in the grid and will take decades to convert.

I am not for or against ev. But they have some major issues to figure out. The claim is less to no pollution. These vehicles are not using plastic,battery's tires. From what I have heard a prius battery lasts on average 50000mi.@ $6000. if i did the math right add.12 per mile. What happens to this battery when it will no longer take a charge. Where are they getting the "minerals" to produce these batterys. I'm sure they are not mining them that would be bad for the environment. Batterys to last the longest like to be recharged at the same rate as they are discharged. I don't know if the chargers are capable but they should be able to auto adjust the charge rate to the average discharge to get the most life from the battery. What is the plan to charge all these ev when a storm hit and the grid is down. Still will need gasoline to fuel the generator, water pumps, chain saws, the list goes on. Solar has issues as well. They have a relatively short life span. And they need to come a long way on producing them with less energy. Currently they require more energy to produce than they can put back into the grid within thei life span. Then when they go bad they go to the land fill. Still need oil make them too they are plastic. Another big strain on these batterys will be heaters and ac. These draw quite a few amps to run where currently the heat is free and the ac you might see a tiny bit more fuel consumption to run. These are just a few issues I see with ev in general and would like to know how they are planning on being more green before I truly get behind them. Gasoline was used originally because it was a by product from making kerosene for gas lanterns and was being thrown away the ice turned that into a usable product. Electricity is nice when it works. But there are so many times that it doesn't and when you are dependent on a single item it is easy to get screwed.

Google mining Lithium if you realy want to know,its way cleaner then driling for oil.

Tesla new 4680 batery will last milion miles,and it can be recycled at the end of its life.

Tesla heater is very eficient even in winter look up some videos from people living driving in Canada in winter,sure the range is less but still doable.

We never had electricity shortage in Canada yet in my forty years living here.
and yet people complain about Goverment all the time Lol

I know nothing about Prius batteries but most EV LI batteries Are warranted for 8 to 10 years and or 192000 km. Projected life is actually north of 500,000 km. The cab companies around us all run Tesla’s and many of their 2014 fleet have north of 300,000 km.

Cooling and heating don’t use much in comparison to the motive requirements. An EV is a good place to be stuck in a traffic jam in winter or summer. Ask me how I know. :). Most new EV’s utilize heat pumps to improve efficiency.

The battery’s have BMS’s to control charging rates and currents.
