Perhaps you, like me, have considered investing in a home battery system — not to go “off grid” so much as to survive blackouts. Simply having solar does not give you such protection, because when the grid goes down, your solar panels do not generate electricity. That’s required by power companies, because they don’t want you pumping electricity into downed power lines as their technicians work to repair them.
Personally, I’m holding out for a future in which the energy stored in my EV batteries can be tapped to power my home during a blackout. There’s a term for this called vehicle-to-grid, but a more accurate term would be vehicle-to-home, since it would be done in isolation from the grid.
Because I have two EVs with combined battery capacity of 170 kilowatt-hours, I have a lot of stored power available to me at any time, even if those cars are not fully charged. For example, 100 kilowatt-hours can provide 5,000 watts of household electricity for 20 hours.
There are commercially available inverters for creating a 120-volt outlet in any car, either gas or electric, but inevitably some automaker — probably Tesla — will create an interface that allows for the electricity stored in one’s EV battery to be tapped for household use during a blackout.
Several electric trucks are going to hit the market in 2020 and beyond, and each will have 120 and possibly 240-volt outlets for field power, which is a good start. You could run an extension cord to power critical home appliances.
You may think this claim is counterintuitive, but consider the following:
Electric cars never need to warm up. Get in, put it in drive and go! (In Teslas, there’s not even a “Start” button.) Moreover, your cabin will be warm in less than 1/2 mile, because it doesn’t depend on an engine warming up.
You’ll never break down. There is hardly anything to fail. Remember, it’s just a battery and a motor (or two). You’ll never stall and you’ll never need a boost. There are only 50 moving parts in an electric car. What can fail? I like to tell people that the only time you’ll see an EV on the side of the road is if there’s an accident or a flat tire or the driver needs to duck behind a bush.
With their low center of gravity and 50/50 front-to-back weight distribution, electric cars handle better and more safely on wet or snow-covered roads. The battery in most EVs is mounted underneath the cabin. My AWD Teslas perform better in snow than my AWD 2009 Lexus RX 400h did. Here’s a 11-minute YouTube video of all three Tesla models being test-driven on Tesla’s Alaska test-track:
Imagine the worst winter scenario, where you get stranded in the snow and need to survive overnight or longer in your car. An EV is perfect for that situation, because you won’t have to stop and start your gas engine to keep warm and worry about carbon monoxide poisoning. The EV will lose less than 5 miles of range per hour to keep you warm. And it won’t matter if your car is upside down. If you charged your car beforehand, you’ll have long-term warmth.
One of my favorite EV features is the ability to leave the climate system on when I go into a store or meeting on a frigid (or super hot) day. When I return to the car, it will be at 70 degrees. If I’m going to be in a long meeting, I can turn on the heat or A/C using my smartphone app as I’m leaving the meeting room and know that the car will be comfortable by the time I get in it.
As I wrote last month, the best deal in electric cars is a used one. According to Kelley Blue Book (www.kbb.com), my good-as-new 2015 Tesla Model S 70D has a private resale value of $33,402. That is crazy. I paid $93,000 for it new.
This was the 6th year that Golden Real Estate has been the site of a local “Drive Electric Week” event.
This year we got our first glimpse of EVs built to compete with Tesla. I got to drive the new Jaguar I-Pace and ride in Audi’s eTron, and they are certainly worthy competition for Tesla in the luxury EV field.
The Jaguar has four electric motors, one in each wheel hub, which is an improvement over Tesla’s two motors and is likely to become a favored design for high-end EVs.
The Audi eTron has dual electric motors, like Tesla, centered between the front and rear wheels.
While these are worthy competitors to Tesla in the luxury market (and there will be others), I don’t think Tesla has anything to worry about thanks to its proprietary Supercharger network throughout the U/S. & Canada and worldwide.
ICYMI: Video of EV Roundup
I have posted a 6½-minute video of last Saturday’s “Drive Electric Week” event. To find it, scroll down .
There’s a similar event Thursday, Sept. 19th, 11-2 in Denver’s Civic Center Park. Dealers will be offering test drives, too, and the first 100 people to request a test drive will get a free lunch! Also, there’s another EV roundup Oct. 5, 4-6 pm as part of the Metro Denver Green Homes Tour. More about this next week.
We already have 14 EVs registered for the National Drive Electric Week event in Golden Real Estate’s parking lot at 17695 S. Golden Road, Golden, on Sept. 14th, 10 a.m. to 3 p.m. We have all 3 Tesla models plus models from BMW, Jaguar, Chevrolet, Nissan and Hyundai. If you have another brand, please register it at www.DriveElectricWeek.infoand come show it off. If you want to be an attendee, you can reguster at the same site.
A couple weeks ago, I wrote about my 50th reunion at MIT. What I didn’t say in that column was that Rita and I drove there in our Tesla Model X. After the reunion, we drove north to visit my sister Susan in Maine, then into Canada to explore Quebec City. Returning from there, we drove past Toronto the morning after their NBA victory, noticing many “We the North” banners. Over a 16-day period, we drove 4,800 miles strictly on battery power, stopping at gas stations only to clean bugs off the windshield.
This was our second cross-country trip in the Model X. The first one was to Seattle a year ago. Four years ago we drove to Connecticut and back in a Tesla Model S.
People always ask whether it was hard finding charging stations. No, that’s never an issue in a Tesla, because when you put a destination in the navigation system, it identifies the Supercharger locations along the route and directs you to them like any other destination and tells you how long to charge to reach the next one. These locations are usually adjacent to the highways you’d travel anyway, so it adds little distance to the trip, and the charging sessions are rarely over 50 minutes. Best of all, since we enjoy lifetime free supercharging, the electricity was free. The only cost of the trip was the wear on the tires, various tolls, food and lodging.
I used the Tesla’s self-driving feature constantly to maintain my desired speed and to stay in my chosen lane. Cruise control is automatic, slowing down based on the vehicle ahead of me and maintaining a safe separation. These features make driving far less tiring and far safer. The car would alert me if it didn’t sense my hand on the steering wheel for 30 seconds, which is a good safety feature. I wish you the same opportunity.
