Actuality examine on the electrical automotive

Guest contribution by Richard Fowler

First of all, I like the idea of ​​an electric car. I like "fully electric". I have an electric washing machine, an electric weed eater, an electric lawn mower, an electric robotic lawn mower, an electric toothbrush, and an electric air pump, to name a few. I drove an electric car and it was fun to drive. Now they have a range of up to 250 miles. For an additional $ 9,000, you can get a range of up to 300 miles. When you drive your car to work, you can charge it between 10:00 PM and 10:00 PM. and 6 a.m., which is great for Howard Electric. At our current special rates, you can cover 250 miles for less than $ 2.50.

Believe me, I and most of the other cooperative managers in the country would love to see an abundance of electric cars. If every member of our cooperative bought an electric car tomorrow and slowly charged their cars during off-peak hours, we could probably cut our electricity tariffs by 15%. Why this? Because we wouldn't have to upgrade our power lines. These power lines were designed and constructed for peak hours (6 a.m. to 8 a.m. and 4 p.m. to 8 p.m. in Howard's case). If you were charging your car during off-peak hours, you would use these power lines during off-peak hours too. We wouldn't have to upgrade your transformer because it was also designed for your peak load. The same applies to your substation, your transmission lines as well as the coal and gas power plants – all designed for your “peak consumption”. Hence, off-peak electricity use should be the cheapest energy available and with our demand for times of the day it is too.

So yes, I want electric cars to be successful. But sometimes what we want requires a reality check. Whether it's electric cars that I want or a carbon-free world that those campaigning for the green New Deal want, both groups need a reality check. I'll write about a reality check for the green New Deal later, but today … we're talking about a reality check for electric cars. For the most part, I don't think electric cars will be anything more than commuter cars. Here's why.

We have done our best to inform you of a KW charge versus a kWh charge, and you now have both on your bills. A car charger that charges slowly overnight isn't a problem, but when you're on the move, you don't want to wait 8 hours for your car to charge. You want a quick charger. The fastest charger to date is a 500 kW charger that charges a car in 10 minutes. Tesla is working on a 550 KW charger. If you trickle charge an electric car, the batteries should last about 10 years. However, if you quickly charge an electric car, the battery life will decrease significantly, and at $ 6,500 per inhabitant, these batteries aren't cheap.

Imagine a charging station instead of a gas station that has eight of these 500 kW chargers installed. That is a load of four megawatts, more than all of our large electricity accounts put together. For this charging station, you need a substation that costs $ 1,000,000 without upgrading the transmission lines to power the substation. That too will cost hundreds of thousands and that additional load equates to a new power plant costing millions – and none – solar and wind power for the most part do not provide reliable peak performance, but rather unreliable intermittent performance.

And it's worse for 18-wheelers. An ongoing study in California, Oregon and Washington has planned a 10 MW charging station for 18-wheeled electric bikes. How many petrol stations are there currently for 18-wheelers in our country? If you convert sixty of these to 10 MW electrical loads, you have the equivalent of our largest coal-fired power plant. This will require more million dollar substations and more transmission line upgrades, which will be very, very expensive. On the upside, these 18-wheelers can travel 500 miles on one battery pack, but these batteries weigh 5 tons which, along with their normal load, could test legal limits for heavy haulage on highways in several states. I really hope they succeed, but the electrical infrastructure to make this happen is a very big mound and will likely require more carbon-based coal or natural gas power plants (unless we're ready to switch to nuclear).

Some have theoretically argued that reversing the flow of electricity from tens of thousands of cars to the grid at peak times could balance the grid and avoid adding more peak power plants. In other words, the electrical grid would use the charge from the car batteries, so the owner would have to charge before driving. The problem with this theory is that people are unlikely to be spending $ 40,000 to $ 80,000 on an electric car so they can balance the grid. If they spend that kind of money, it will be to drive the car.

System peaks are on the hottest and coldest days of the year. If you drive your car and use your heating or air conditioning these days, how much excess battery power do you expect to need to charge to charge the grid? It is these hottest and coldest days that determine how many power plants we need. I don't think backflow is a sensible solution to avoid higher peaks caused by SUVs and trucks quickly charging their vehicles at peak times.

Unless someone (either our members or taxpayers) has money to buy these fast chargers, substations, transmission upgrades and power plants, they are unlikely to become a reality.

For the sake of discussion for cars, let's downgrade the chargers from a 500kW charger to a more reasonable 50kW charger (8 times the top of an average home). These are the fastest chargers Kansas City Power & Light (KCP & L) is installing in Kansas City.

These 50 KW chargers charge a car in 93 minutes. So you drive into this charging station and there are three people in front of you, each taking 93 minutes. That's a waiting time of 4½ hours plus 1½ hours to charge your car. Many of KCP & L's chargers are level 2 chargers. These take four hours to add 200 miles of travel time. Not a bad wait when your on the golf course.

How far can I go with a fee? As I said earlier, these newer electric cars can now travel up to 250 miles on one charge … unless you turn the heat on. Heaven forbids you to turn on your heating. Miles decrease 25% when you need heat. Northern states could struggle with this problem. Slow charging stations in the workplace could make longer distances more reliable and work with the existing infrastructure. However, if you want to rely on a slow charger to get home, it has to be dedicated to you.

Electric cars are estimated to cost six to ten thousand more than a gas car. These cars require 70% fewer parts than gas engines and 30% fewer workers to assemble them, resulting in the loss of jobs and a more expensive car. On the positive side, the cost of charging an electric car at home is much cheaper than gasoline. If you are not using a quick charger. Most of the cobalt in lithium batteries comes from the Congo. The Congo continues to increase the cobalt price and the Congo is considered an unstable country.

In 2012, CAFÉ standards required cars to travel an average of 54.5 miles per gallon by 2025. President Trump has reduced this requirement to 37 miles per gallon. Apparently, General Motors and other automakers believe that politics will bring this standard back to 54.5 miles per gallon by either 2020 or 2024, so they are pushing that target. The only way to achieve this goal is to meddle a significant amount of electric cars. General Motors expects 20% of its auto sales to be electric by 2023.

The Green New Deal would make all vehicles electric by 2030 and the proposed "OFF Act" would make all vehicles electric by 2035. In this case, traveling around the country could be a circus. An electric car makes sense for a commuter car, but for traveling around the country if you don't want to wait long, you'll need a gas vehicle if you can find one.
