Two Years of Driving Electric

Yesterday was two years to the day that I picked up MINI-E #250 and began a journey that would alter my life in many ways.

I had no idea I'd grow to enjoy electric drive as much as I did and I really had no idea I would become such an outspoken proponent of battery electric vehicles. The past two years have been a great ride, both figuratively and literally. The electric driving experience I have had with the MINI-E has been so great it has convinced me that I'll be driving electric cars from now on. The great news is that it is now possible, and that wasn't the case in 2008 when I filled out the application to take part in the MINI-E trial lease program. Back then you either had to buy a $100,000+ Tesla Roadster or build your own EV if you wanted a real, highway capable electric car.

Since I didn't have a spare $100k lying around or the time necessary to do a full conversion, I signed up to participate in the MINI-E Field Trial, not knowing at the time this program would take me off gas for good.
The program was initially supposed to be a one year, closed end lease. At the end of the year I would hand back the car and go back to gas, since there would still be no electric cars available for purchase at the time. However BMW offered one year lease extensions and now offered another six month lease extension, effectively making the MINI-E Trial Lease program 30 months for those who wish to remain in the program.  Six months from now, I and the other MINI-E pioneers that stayed in the program can transition directly from the MINI-E into the BMW ActiveE, the final test car before the 2013 BMW i3 hits the market. The ActiveE is a 24 month lease and when it ends, the i3 will already be in showrooms. The significance of this is that BMW has offered me a clear uninterrupted gas-free path, from the day I took possession of my MINI-E two years ago to the day they will offer the i3 for sale. No other car major auto manufacturer (that isn't named Tesla) can claim they have done that for any of their customers. I know the MINI-E group was small, but I think BMW deserves credit for this program. Sure we have to pay to lease the cars, and they are getting valuable information form these field studies, but no other major car maker took any of their customers off gas for good in 2009.

Being in the program has made me more aware of my energy usage, both in the car and at home. I installed a solar array, bought Energy Star appliances, changed all my lighting to either compact florescent and LED bulbs, adjusted my programmable thermostats, replaced old drafty windows and are generally more aware of reducing wasted energy. In doing so I have reduced my home electric usage about as much as I need to charge the car, effectively eliminating my personal fuel expense and the solar array eliminates 90% of my homes electric cost. I even drive more efficiently, using the regenerative braking as much as possible and I definitely find myself driving slower, even when I'm not driving the MINI-E.

I have driven the car 59,500 miles so far. That's about 30,000 miles a year or double what the average American drives and the MINI-E handled it without any problem. So much for electric cars being only good for low mileage drivers that only drive short trips! Oh and another thing, I've never been stranded on the roadside because I ran out of charge. Something that everybody that hasn't driven an EV seems to be worried about. The car has been extremely reliable and has required very little maintenance at all. Another thing that I'm really impressed with is that I have now charged the car over 1,100 times and it still has virtually the same range it did when it was brand new. I know at some point, there will be battery degradation, but I can tell you for certain, it isn't measurable yet and I have the data to prove it.

Somewhere in an underground storage tank at the Lukoil station I used to go to before I got the MINI-E, there are about 3,300 gallons of gas that wouldn't be there if I never applied for the program. You see, I always went to this one gas station to fill up as it was conveniently located on my route from home to work. It I had continued to drive my Toyota Tacoma for the past two years and 59,500 miles, I would have needed to buy about 3,300 gallons of gas as the Tacoma gets about 18mpg. This would have cost me about $10,000. I would have also needed about a dozen oil changes and would be looking at a major (recommended) tune up for the truck. Electric cars like the MINI-E require virtually no maintenance and after driving 60,000 miles you would probably only have to replace the tires and wiper blades.

So yeah, it's really been a great run so far. I really look froward to the BMW ActiveE, but I'm going to miss the minimalist attitude of the MINI-E. Small, great handling, fun to drive and still the feeling of  "efficient basic transportation" that I like. Electric drive in a MINI Cooper platform works and BMW would be foolish not to bring it back in a series production sometime in the future.

I always believed electric cars might be our future. They reduce our dependence on foreign oil, keep our energy dollars in local economies, improve our country's national security and are much better for the environment. The past two years in the MINI-E program proved to me that I was right.

How Much Electricity Will An Electric Car Use?

With all the talk about electric cars lately, one thing that I keep hearing is people wondering how much electricity will an EV need? Are they simply ditching the gas pump only to pay just as much in their electric bill? I made a post on this subject last year and I think it's important enough to re-post it again for anyone that hadn't seen it last year. With gasoline prices north of the $4 mark now and electric cars in the news, I have had a lot of new followers lately and I still get emails from people that ask me just how much does it cost to charge the MINI-E; so here it is, again....

One of the questions that people frequently ask me about the MINI-E is "How much electricity does it use?" Sometimes they'll just say "I love the car, but I wouldn't want to see your electric bill!"

When I tell them the car costs between $3.00 and $6.00 in electricity to go 100-120 miles they usually smile and say "Wow, that's great". The reason the range is between $3.00 and $6.00 is because there is such a difference in electricity rates throughout the country. The MINI-E has a 35 kWh battery pack but only 80% of the pack is usable which means it has 28kWh of available power. That 28kWh can move the car between 90 and 120 miles depending on how efficiently you drive. It is less in the winter months because the heater uses a lot of energy, but for most of the year these numbers are correct as an average.

The national average cost for electricity is $.12 per kWh which means it would cost the average person $3.36 to fully charge a depleted battery on the MINI-E. However rates do vary. I pay $.11 per kWh at my restaurant in Montclair, lower than the national average, but it costs me $.18 per kWh at my home in Chester, only 30 miles from Montclair. So if I "fill up" at work it costs me $3.08 but at home it costs me $5.04! Obviously I take advantage of the lower rates and charge at work as much as possible. So basically for what it costs for a gallon of gas today, you can drive an electric car like the MINI-E or Nissan LEAF about 100 miles.

Since I have a solar PV array at my home, I sell the electricity back to the utility at the rate they sell it to me ($.18/kWh) so every kilowatt-hour that charge at work saves me $.07. The average person drives about 15,000 miles per year. If they had a MINI-E they would need to use about 4,200kWh to drive 15,000 miles. If you use the national average, you would pay $504 for fuel for the entire year. If you use my rate at my restaurant, it's $462, at my home it's $756. So figure anywhere between a $40/month and $65/month increase in your electric bill if you had a MINI-E and drove it the average of 15,000 miles per year.

One of the great things about electric cars is that you can easily reduce your electric bill by $40 to $60 per month just by being more efficient and therefore completely eliminate your transportation fuel cost! You can't use less gasoline unless you drive less, but you can reduce your electricity usage and still drive as much as you always have. Simple measures like a programmable thermostat and the use of compact florescent light bulbs can make a big difference. In fact, five 100 watt light bulbs left on continuously for a year use the same amount of energy as it takes to power the MINI-E 15,000 miles! Here's how: five 100 watt light bulbs use 500 watts per hour. In 24 hours they use 12,000 watts or 12kWh. In 365 days they use 4,380kWh. What does the MINI-E use to go 15,000 miles? Remember above I calculated it to be 4,200kWh? So five 100 watt light bulbs use 180 more kWh than it takes to power 3,200lb MINI-E for 15,000 miles!

If you take a good look at your home electricity use, I'm sure you can reduce your usage enough to drastically offset the cost of electricity to power an electric car, if not completely eliminate it. Then, every penny of the money you would have spent on gasoline can go right into your pocket!

Back in the Drivers Seat

Good news. After only about 5 hours after dropping off #250 for my 42,000 mile service and to check out the fan issue I got a call from my service manager Vinnie to tell me the car was all set and ready to be picked up.

Since I was at work and had a busy night in front of me (a party of 50 was booked) I couldn't leave and get the car so I picked it up this morning on my way to work. Vinnie greeted me as he always does, with my keys, an explanation of what services were performed and a smile. Service writers can help to make a usually unpleasant trip to the dealer more bearable by explaining everything they needed to do and simply being personable and Vinny does a good job at both. I am happy I got my MINI-E from Morristown MINI because I am very pleased with the overall job the service department does there. The car is always cleaned and charged when I pick it up. The only criticism I can really offer is that Morristown MINI doesn't have many actual MINI's to give out as service loaner cars and they use Enterprise Rent a Car for this. I know most dealers use this practice (When I had a Mercedes they also used a rental company for their service loaners unless you were a "Gold Circle" customer and probably needed to buy ten cars from the dealer to qualify) In all my service trips for the MINI-E (about ten) I only got to use an actual MINI once and it was a clubman. I really liked driving the car and it even made me think about buying one. I think this is a great way to showcase their products and possibly get their service customers to want to upgrade to a newer MINI or clubman. Oh well, what do I know?

Anyway, #250 is back on the road and I only had to shell out $8.00 for gas yesterday. Not bad, but consider this: The same miles driven in my MINI-E would have cost me about $2.65 in electricity, and that was for just ONE DAY of driving!
