To me, it does not matter how much it costs for charging an all electric auto. It is still prohibitive. I remember when people were introduced to "all electric homes." They were told energy would cost ONLY "pennies!" Yeah, pennies... When they got their Monthly electric bill, it totaled over $1000.00 a month. There is no way that the cost of total electric anything is going to be cheaper than fossil fuel at this point in time. Hybrid cars come close to being economical, but that's all. Oh, and remember, those electric filling station still HAVE TO RUN ON FOSSILE FUEL...GAS!!!

Take fuel consumption at the rate of 1GPM. After 3 minutes you don't have 3 GPM you have consumed 3 gallons....

Oh, I paid attention.......

So part of the problem with the lack of infrastructure is that it requires more real estate to park all the charging EVs.

BebuLamar

the math is the same. The rate of 3 gpm that means 3 g / m. after 3 minute = 3 g/m x 3 m = 3 g xm/m = 3 g.

By the way the rate of kW cant be stated in another way as 3 kJ / s kilo Joules per second. and the 70kWh is 70kJ.

Only 100,000 pennies.

LOL!

But still, you CAN count the cost in pennies!

Replace GPM with KWH, what do you get as an end result?
KW.......

BebuLamar

GPM isn't the same as KWH. Gallon per minute is Gallone divided by minute. kilowatt hour is kilowat times hour. People tend to think kWh as kW per hour but it's not. It's kW for an hour.

As an engineer, I have always believed that one should always select the correct tool for the job to be done. This is definitely the case for EVs.

I am not an advocate for the total elimination of petroleum-fueled vehicles. EVs, at least at today's level of technology, are NOT the best choice for everyone. My wife and I found ourselves in need of a second vehicle. I needed to drive out of town several times a week to care for my mother. With one vehicle this left my wife with no car. Driving to my mother's home was around 75 miles roundtrip and I was driving there 3-4 times a week.

I looked for a suitable and economical used car but for what I wanted to pay most of the used cars were worn out, damaged, or just unreliable. Stopping at a local Nissan dealer to look around they offered me a 2-year lease on a Nissan Leaf at a low down payment and low monthly payment. In addition, our apartment had just installed several EV charging stations with one located just outside our unit.

The Nissan Leaf offered the range I needed, low costs, and almost zero maintenance. In fact, I probably will not even have to buy tires before my lease ends. It met my needs for this application. It was and is the right tool for the job.

Is an EV right for everyone? No, I do not believe so. I would NOT want to travel across the country or even beyond the range of my EV unless I was positive I could recharge easily. Part of the problem with charging stations is that even when you find a charging station, it may not work. Lots of people are installing charging stations but are not maintaining them. I have visited a few that were not working properly. I think this is a big problem.

But EVs do have a place. If one is retired and living in a warmer climate for most of the year and drives mainly to do their local errands or shopping, the EV may be ideal. They are low maintenance and if they can be recharged at home in your driveway or garage, gas stations would never be needed. If one drove less than 100 miles per week and the owner could recharge at home, the EV would be almost perfect.

People seem to purchase cars based on their worse case use. I have had friends purchase vans or large SUVs giving the reason that they will need the space for vacations. But then they use the vehicle for their daily commute the rest of the time. Driving a large vehicle 50 miles daily for commuting, a common thing here, is very expensive even if the gasoline prices are low. Tires and periodic maintenance can be expensive. Why not buy a cheaper, more economical car to commute with and rent a larger vehicle for the once-a-year vacation?

I see a similar issue with EVs. EVs may have a place as a local commuter car to save energy and maintenance costs. However, I do not think they are the answer to all needs. At this time they are NOT the right tool to take cross-country or other long trips beyond their range. I think this winter has also shown that EVs may not be a good fit in areas with severe cold weather.

So, pick the right tool for the job. Just like in photography!

Oooookaaaaayyyyy.....

KW for an hour, gallons for a minute..... right.
They're both rates.
But one is gallons and one is Kilowatts.
So I suppose that makes them different.

KWH is kilowatts per hour.
Kilowatts times hours and gallons times minutes provide the consumption over that time period for those units.

This one may confuse you:
If you use 10 KW in 30 minutes the rate is 20KWH.......

As I stated in a previous post, I drive an EV and it is cheaper, at least by measuring the amount of money coming out of my pocket, to drive my EV than my gasoline car. That calculation is being made using local gasoline prices at around $2.80 gallon, at pretty reasonable cost.

As far as an all-electric home. My home now is all electric and I have never had a bill more than $150 and we run the AC in the summer and the heat full time in the winter. Our average bill is usually around $80. There are too many variables to say that all-electric is more expensive.

the gallon per minute is rate but the kWh isn't rate. It's the quantity of energy and it's kind of like the gallon. In fact you can call 1kWh as 1kJ. For an hour isn't the same as per hour.

BebuLamar

Not you got it all wrong. You use 10kWh in 30 minutes your rate is 20kW. The kW is the rate. Watt is the unit of rate.

If something relates to time, it's a rate.
But you can believe what you want.
We're done here.
