Update to back of napkin math using first month’s SCE Time of Use Tariff


It’s time for an update.  As a response to my $0.31 per kWh price for charging my ActiveE on Southern California Edison’s Domestic Tariff, I signed up for Electric Time Of Use (TOU). Now there are TWO flavors of the TOU tariff.  One requires a separate meter, the other does not.  The approximate cost for the separate meter and installation at my house was an additional $2,000 to $4,000.  Since, we were not sure if we would be staying on Electric after the two year closed-end lease of the ActiveE, we decided to go with the one offered for customers with a single electric meter.  At this point, barring the lack of good choices after the 2 years, we probably will go ahead and get at least a replacement electric vehicle.

So what did we find out after the first month on the new tariff.  First, let me spell out what assumptions were made to calculate the amount of energy used by the AE.  I could have gotten more detailed (counting ALL the emailed kWh usage identified by my Chargepoint EVSE, but decided that I did not really want to do all the calculations and since most of my charging is done at the super-off peak hours and very few outside of these times, that I would overstate the amount of energy and calculate based on the total super-off peak usage AND 10% of off-peak charging to come up with my model.) but I would’ve run out of room on the back of the napkin.  Bottom line, in the new month, I came up with $0.12024 per kWh to charge this past month under the winter rates.  This assumption puts me at the cost to fill up at home at $1.20 per day

So, using the 70 mile number – from my electric cost per mile last month is approximately $0.01714 per mile.  After two months of driving, I have noticed that my average roundtrip is actually a little higher than the 70 mile number.  Let’s call it 85 miles…  So, using this mileage, I was able to recalculate this cost down to $0.01412 per mile.

Using the revised mileage numbers, 407 miles is $5.75 vs. $60.00 approximately 1/12th the cost of ICE.

Folks with lower kWh pricing obviously come out a lot more.  In fact, it’s practically free for those that are on solar power, though not really free, since installing solar DOES cost money.  Now that BMW got a nice group discount at 35%, but still not “free.”

Of course the subsidized power may disappear as electric cars gain greater traction, but there’s a lot of room to go before it gets close to the same level as an ICE car of a similar caliber.  Additionally, it would seem that my rates are bound to go up when Summer Rates kick in, so I will have another update when those bills come in.

Range Anxiety and the Longest One-Way drive so far!


I’m sure others have done longer and I’ve had longer days (with multiple charge stops… personal record – 175 miles in one day (two charge stops)) however, aside from Las Vegas, folks around LA normally think of driving to Santa Barbara, Palm Springs, or San Diego to be a long drive, so I figured to try one out.

Since we live in the Southern Tip of Los Angeles County, it seemed best to pick San Diego as the destination.

Trip planned, remote charger identified.  Time to conquer range anxiety…

Our planned stop – The North County Transit District stop in Oceanside.  Ideal choice because on May 6, they were running extra trains for the weekend (Cinco de Mayo was just the day before and there were still festivals and a Padres game going on).

This is a 65 mile journey one way, of which around 25-30 miles near the end there were not only NO public chargers listed on any of the Apps, but no gas stations Between San Clemente and San Onofre, so even ICE vehicles were warned of “no services for the next 20 miles” .

The plan was to get to the Train Station and hop on the Coaster to get down to San Diego.  Blink Network and the North County Transit District had both installed 6 chargers at the station and taking the train from here would provide a day’s worth of entertainment.

I debated as to using the cruise control and setting it at a moderate 67-68 miles per hour on the ActiveE (it overstates it’s speed and that would get me around 65) but opted to enjoy the drive and use the pedal manually.  I decided to go Eco Pro and also was not driving as aggressively as I normally do and found myself being passed by many cars (that last stretch by San Onofre Nuclear Power Plant tends to be a really fast one)

Though the navigation had recommended that I use the toll road around the El Toro Y. I opted around it as that route has a lot more hills and I decided on staying on the 405 to the 5 freeway as it is considerably flatter and I wanted to arrive at my destination with as much charge as possible (to minimize the charging time for a full charge.)

This conservative driving worked wonders for my range.  I ended up at the train station with 25 miles left and State of Charge (SOC) around 20% (the car did its customary warning at 27 miles to go).  However, plans #1 and #2 for the day was shot as I arrived at the chargers only to see the Coaster pulling away from the station and the Amtrak soon after.  There were five chargers available as one was being used by a Leaf and I decided to plug in and charge.

Luckily, we had a plan #3.  Four hours to charge the car and a few miles away was the Carlsbad Premium Outlets.

So, we decided to jump in a cab ($23 one-way, $25 with tip) and get down to the outlets to do some shopping. This is a smaller outlet a stone’s throw from Legoland.      It has a lot of the same stores one finds at other outlet stores around Southern California, but it does have a nicely stocked Crate & Barrel Outlet, not that we ended up getting anything there.

The shopping center was well attended, but not crowded and the sales were actually very attractive.  Ended up picking up a few items that more than off-set the round-trip cab fare ($50, I did $25 with tip on the return cab trip as well.)  Additionally, the food choices near the outlet stores were quite good (namely a PF Chang’s, and BJ’s across the street and Ruby’s Diner in the outlet stores) and it helps that Starbucks had the Frappuccino Happy Hour going to recharge during our 4 hour shopping trip (that’s about 3 3/4 hours longer than the better half can stand).

We made it back to the ActiveE right as the blue light stopped blinking.  I literally saw the car blinking when the cab arrived at the train station, and stay off as I walked up to the car to get it disengaged from the Blink Network charger.

Having the confidence of making the range on the Southbound trip earlier, the Northbound trip was a lot more pleasant.  I stayed on Eco Pro, but definitely drove a little more aggressively.  I stayed OFF the Toll Road route as I wanted the opportunity to get off the freeway at any of the cities in between.

The roundtrip was approximately 135 miles with a single 4.25 hour charging session in between.  I arrived home with about 30 miles left on the car and about 25% SOC.

Charge It! – Great food near public chargers #1 in an ongoing series


One of the things about charging my ActiveE at public chargers is trying to figure out what to do while I wait for a couple of hours.  Shopping center public chargers are great ’cause there’s a ton of stuff to do at shopping centers. However, as much as I like to shop, it gets boring.

So, I figure that one thing that would be very helpful for readers of the blog is figure out what great food places there are around some of the public chargers that I use. The ActiveE has provided me with nice opportunities to slow down and enjoy life at times.  So, rather than fast food, some great food near chargers (read walking distance).  Though ever since I got this car, I’ve found myself walking more and more. (the L2 charger nearest my office is 3/4 of a mile away.) So I get a mile and a half walk most work days (for non-SoCal readers, that’s a long walk for Southern Californians.)

So, without further ado…  Let’s go with the first one…  Breakfast is the most important meal of the day, so I figured to choose my first location accordingly.

The Helms Bakery District

This place is great. Two Clipper Creek J1772 L2 chargers are available and parking is free.  So, you can always shop for furniture and other home stuff at this location.  But, how often does one need to buy a new couch, table, bed, or chair.  At the prices that they are sold at the Helms Bakery District, not too often.

So, it makes it the ideal spot to grab something to eat.  The question is what time of day are you at Helms Bakery.  Breakfast or a snack at La Dijonaise is always great.  I’ve found it a great place to grab a cafe au lait and a macaron. They make some of the best macarons that I’ve ever had.  The one pictured below is a coffee flavored macaron. They have several different flavors, and the coffee is my favorite, the chocolate is pretty great as well. I’ve tried a raspberry, orange, almond, and others and the worst is better than most places macarons.

A little pitstop to recharge myself and my @BMWActiveE at the Helms Bakery charger...  Enjoying a Cafe au lait and Macaron!

This one was a little too tart..

Just tried today – Chocolate Eclair..  It was good!

Chocolate Eclair at La Dijonaise

Really the only other thing I’ve grabbed at La Dijonaise has been a raisin roll.  So, I can’t comment on the other food, (one of these days I will, just not today) but they really do the baked goods well.

Dinner or lunch (on some days) another popular place to go at Helms Bakery is The Father’s Office. I’ve been there once. The burger is good and it is very popular (there seems to be a good crowd at The Father’s Office making it a good place to hang out). It has been considered one of the top burgers in LA. However, I’m the wrong guy to pick burgers. I can tell good from bad, just not good from great nor any other superlative to describe burgers.  According to experts, this burger is really good, so I take their word for it.  If you prefer the reviews of others, it does pretty well on Yelp as well not too bad on Zagat either.  In all, breakfast, lunch, or dinner, Helms Bakery is good.

The J1772 chargers and easy access 24×7 makes it a good place for an Electronaut or any other EV driver in LA to stop by the Helms Bakery.  This place is a good place to go and charge it! (and get yourself a fill up as well).
