The Quiet Revolution
Apr 25, 2018
A summery of a EV power point presentation I am working on and why I think electric vehicles are about to take over the marketplace over the next ten years.
We here at the Electric Vehicle Organization SNM have been working on a power point presentation about electric cars. On April 30th, 2018 I shot two videos for You Tube doing the entire The Quiet Revolution power point presentation inside of 30 minutes total time or 15 minutes for each segment. The following two links are for this power point presentation.
I was inspired to do the presentation by the video put out by Fully Charged on “Barriers to EV Adoption” for which I added the following link.
I think we have nearly arrived at parity for EV’s as a vehicle choice for most people as to price and range, it is just a matter of most people not knowing it yet. This problem is what inspired me to do a power point presentation.
The Sustainability Officer for Las Cruces, NM says she is forming a citizen committee to advise the city on adopting EV’s and ask me if I would serve on it. I told her I would and felt a power point presentation might be useful in that venue also.
One of the places we use our 20 miles of EV only range for our PHEV is when we are driving in the city. The slower speeds and stop and go driving is where electric drive really shines and is at its greatest efficiency. We even gain range traveling from the east side of Las Cruces to the west side of town because of the drop in elevation.
If the city is considering buying or leasing electric cars for the city fleet (and they should) they need to understand that city driving is where EV’s really are at their best. Whereas an Internal Combustion Engine vehicle get its lowest mileage returns in city driving. Given EV’s get three to four times the mpg-e as a comparable ICE vehicle they are the best vehicle choice the City of Las Cruces (CLC) could make.
Another place we use or EV only mode is accelerating up to highway speed before putting the car into cruise control. The gas engine is in its most efficient operating regime when it is traveling at a steady speed on the highway, but not accelerating up to cruising speed. We would of course use the electric drive for all our driving if we had a pure BEV, but we don’t, yet.
I have been looking at the Hyundai Kona 2019 offering as Ev due out this fall. I like that it has a 250 mile range 64 kWh battery pack. Because Hyundai already sells gasoline variants of this vehicle a natural comparison of one to the new EV version was a natural. A 64 kWh battery is the equivalent of a 1.952 gallon gas tank. The gas version of this vehicle is rated at 32 mpg on the highway. This means that a gas powered Kona with only a 1.952 gallon gas tank would only have 62 miles of range. I find it useful to turn this this so called range issue EV’s are supposed to have on its head like this to showcase the startling inefficiency of the gasoline engine.
The laws of Physics just are not kind to internal combustion engines which tend to waste from 75 to 80 percent of their input heat as waste heat which is not moving the vehicle. I think it was Paul Mc Cready who referred to gas cars as “miniature blast furnaces on wheels”.
Since electric motors are around 90 percent efficient in utilizing their input electrical energy they waste far less energy. Electric vehicle routinely return over 100 mpg-e, while ICE vehicles are doing good to get around 32 mpg on the highway. The higher inherent energy efficiency of electric vehicles is going to make the Trump Administration roll back of the Obama C.A.F.E. standards look laughable over the next ten years as they start taking over the market place.
I am referring to EV’s as the “Quiet Revolution” because they are in fact quiet to drive. Once up to speed essentially you mostly hear wind noise and the thrum from the tires as they contact the road surface. More important the adoption of electric vehicles will take place because they are simply superior to internal combustion engine vehicles in almost every way.
Once some the remaining barriers disappear such as the higher price of battery capacity and EV’s reach price parity with ICE vehicle you will see mass adoption of EV’s. Things being equal the consumer when faced with a choice to two vehicle types at roughly the same price point, one being clearly superior in its performance, and with at least half the operating cost it is not hard to imagine what choice they will make. The remaining barriers to mass EV adoption are battery cost and more rationally spaced rapid charging points for long distance travel.
Lastly I will leave you with this video from “Fully Charged” titled “Volts for Oil” where Robert LLewellyn explains how much electricity is used in England to refine oil into the various products that come out of an oil refinery. One estimate is that it takes 4.5 kWh of power just to refine one gallon of gasoline.
Our PHEV with a 5.5 kWh battery for EV only mode has 20 miles of range. On 4.5 kWh our car can go 16 miles involving just the energy it takes to refine one gallon of gasoline. The energy content in the gasoline is 32.777 kWh and the math says our car could go 95 highway miles which is it's rating. EV's are plainly the better energy investment.
