Lessons learned from a month of EV ownership — Technology Musings — Medium

Good advice from a new EV driver.

I’ve lusted after a Tesla since they debuted, thought seriously about getting a Nissan Leaf too, but it was after I took a test ride in a BMW i3 that I found a perfect happy medium. I picked one up last month and learned plenty in the short time I’ve been driving it. If you’ve ever wondered what it’s like to live with an electric vehicle (EV), here’s a list of things I’ve learned since taking the plunge.

Silent running

I’ve driven an electric car for about 5 months now and discovered a curious effect: Electric cars are invisible to wildlife. Several times I’ve driven right up on a bird, car, or squirrel standing in the road and they only move when I’m within a split second of hitting them. You would think that just the sight of an approaching vehicle would be enough to send them scurrying but this does not appear to be the case. Critters apparently depend on the noise of vehicles for detection the same way many people do.

My first long-distance EV trip

Too close for comfort!

Too close for comfort!

Over the past week I’ve made several trips to visit my seriously ill friend Scott Greenough out at UNC Hospital. I don’t always have the option of taking our Kia Sorento, so I often top off the juice in our Ford Focus Electric and hit the road.

Driving an EV longer distances requires one to do a little math, particularly if one is unsure a charging station can be found at the destination. I figured with my top range of about 75 miles, I would have more than enough to get there. The PlugShare app showed a ChargePoint charging station in the parking deck across from the hospital, so I figured I would be good to go.

Daylight Saving Time for Electricity

Today (or maybe tomorrow? I’m still not sure) is the day that the hours change for those of us on Duke Energy Progress’s Time Of Use (TOU) electric billing plans. When you’re a grid-tied solar electricity provider like we are, Duke puts you on a TOU plan so that you are encouraged to use most of your electricity off-peak. The change in electric season is like Daylight Saving Time for our electric bills.

Peak hours in winter are from 6 AM to 1 PM and from 4 PM to 9 PM. Summer peak hours are from 10 AM to 9 PM. This means we can run our dryer or charge our electric car in the morning, rather than hold off until after 9 PM, which is a good thing.

I made a handy chart to help keep track of these schedules but haven’t shared it yet since I want to incorporate suggestions that Kelly made. Hopefully I’ll get it posted soon.

The magically-filling fuel tank

Earlier this week I got to experience a phenomenon very unique to electric vehicles.

I was driving out of the parking deck at work on a warm day that had started much cooler. Batteries are sensitive to temperature and don’t provide less power when it’s cooler. My electric car had dialed back its expected range on my cooler morning commute and kept it there as my car waited in the cool parking deck for me to get off of work.

As I drove out at the end of the day, the car’s thermometer rose briskly as it went from the cool parking deck to the warm afternoon air. I watched in amusement as my car’s range began increasing as I drove! It was like someone was adding fuel to my tank! I gained 20 miles of range on a six-mile drive.

Only in an electric car can one drive somewhere and actually get an increase in range!

Historic moment: Saudi Arabia sees End of Oil Age coming and opens valves on the carbon bubble – EnergyPost.eu

This is a fascinating read about the oil market that took me a while to really get, but it finally makes sense.

Tl;dr The Saudis are selling all the oil they can now because they’re worried that oil is quickly becoming obsolete. They’d rather sell at a drastic discount than be left with oceans of oil but no buyers.

Most analysts believe Saudi Arabia refuses to cut production because it wants to shake out its higher-cost competitors or because it wants to punish Iran and Russia. There may be some truth in those theories, writes Elias Hinckley, strategic advisor and head of the energy practice with international law firm Sullivan and Worcester, but they miss the deeper motivation of the Saudis. Saudi Arabia, he says, sees the end of the Oil Age on the horizon and understands that a great deal of global fossil fuel reserves will have to stay underground to avoid catastrophic global warming. “That’s why it has opened the valves on the carbon asset bubble.”

Google Wants To Help You Buy Solar Panels For Your House. Seriously. | ThinkProgress

It’s a shame this type of innovation is blocked by North Carolina law.

If you to want to install solar panels on your roof but haven’t yet because it’s too expensive, Google really wants to help.

The search giant, valued at $370 billion, is once again boosting its investment in SolarCity’s residential solar power model by $300 million, both companies announced Thursday. Combined with a new financing structure from SolarCity, the companies say this will result in a new fund worth $750 million to help install distributed rooftop solar on homes across the country.

Is this the fuel cell that will crack the code to the data center? | Gigaom

Microsoft is exploring putting fuel cells directly in datacenter racks and skipping the DC/AC/DC conversion.

The controversial idea of using fuel cells to power data centers has been under discussion for the past couple of years. Probably the most famous project out there is Apple’s 10 MW fuel cell farm, which uses 50 fuel cells from Silicon Valley startup Bloom Energy installed next to its east coast data center in North Carolina.

But Microsoft is just starting to kick off a pretty unusual and innovative project using fuel cells and data centers that could some day draw a lot of interest. Microsoft is working with young startup Redox Power Systems and using a grant from the Department of Energy’s ARPA-E program, to test out Redox’s fuel cells to power individual server racks within a data center.

Why Tesla’s battery for your home should terrify utilities | The Verge

Telsa and SolarCity are working on a residential battery that might let people drop off the electric grid completely. The utilities are sweating.

Earlier this week, during a disappointing Tesla earnings call, Elon Musk mentioned in passing that he’d be producing a stationary battery for powering the home in the next few months. It sounded like a throwaway side project from someone who’s never seen a side project he doesn’t like. But it’s a very smart move, and one that’s more central to Musk’s ambitions than it might seem.

R-Line envy

R-Line-BikeOnBus
Speaking of transit, I see that the marketing director for Cameron Village is trying to drum up support for diverting the R-Line buses from the original mission of serving downtown Raleigh. I’m all for improved transportation around Cameron Village because trying to drive anywhere around there is a nightmare. That said, I’m not sure extending the R-Line is the answer.

The R-Line buses came about through a joint effort of the Raleigh Transit Authority, the Downtown Raleigh Alliance (DRA), and the Greater Raleigh Convention and Visitors Bureau (GRCVB). All three groups helped make the R-Line possible. Cameron Village is not part of DRA and I don’t see that they do much with the GRCVB. Is the shopping center proposing to help pay for this extended service the way these other groups have? If so, I haven’t heard it. It would be great to get everything for free, but someone has to pick up the tab.

Cameron Village already has city bus service (two routes, 12 and 16). It makes sense to improve this existing service and leave the R-Line to do what it’s been doing: giving visitors an easy way to get around downtown Raleigh. That’s why downtown businesses subsidize it.
