i3 Owner Explains Her 312 Mile All Electric Day

Kris charging up at an NRG Fast Charge station
One of the many things that Tesla Motors understands as well as anybody is how a robust Fast Charge network will liberate their customers from being on an "Electric Leash." Ubiquitous DC fast charging stations are, in my opinion, just as important as longer range electric vehicles. In fact, they may even be more important.

BMW apparently shares that opinion and has recently announced that they are getting into the DC fast charge game with a partnership that includes Volkswagen and ChargePoint, and will be installing fast chargers at 50 mile intervals on the East and West coasts to create "Express Charging Corridors." However it won't end with there. BMW is going to continue to invest in DC fast charge infrastructure here in the US, as they realize that they need to participate in creating the foundation for BMW i to succeed.

As with most things EV-related, California is ahead of most of the US when it comes to DC fast charge infrastructure. While the SAE Combo (CCS) fast charge units are only beginning to be installed, there are some already in the ground there, and they are allowing people to take their i3s further in a shorter period of time than they could if they were relying on 240v Level 2 public charging.

Kris & I at a recent i3 meet
Which brings me to the story below that I found interesting.  My friend Kris Kluzak, a former ActiveE Electronaut, offered to write a guest post for this blog detailing a day when she drove her i3 312 miles using public charging infrastructure.  It shows that even a medium-range EV, like the i3, can easily cover hundreds of miles in a day if the appropriate infrastructure is in place.

Here's how it went down, in Kris's words:
 



A 312 mile, all electric day in a BMW i3 REx:

On November 11th, 2014 I was scheduled for a research study for my car in Sherman Oaks, California. From my house in East San Diego County, it is about 160-mile trip one-way.

On any given day this �normal� trip would take approximately 3-4+ hours in any vehicle with an engine (ICE) as the main power source. Those of us living in Southern California know the different routes to take to avoid traffic blunders, and are often looking for the carpool lane when it�s an option.

In order to arrive on time for my 2pm appointment, my husband and I had to build in a few charge/food stops; this set us to leave right after 8am. First, we stopped 39 miles away at the Carlsbad Premium Outlets to charge and grab coffee at Starbucks. *We charged for 30 minutes knowing we had enough range to reach our next stop in Santa Ana. 
 
Like me, Kris's previous electric car was a BMW ActiveE
We next stopped at Crevier BMW, 58 miles from Carlsbad. Just days prior they had installed four DCQC (SAE Combo) stations and we were on a mission to check them out. Normally we would not choose this route through Los Angeles, but since it was a Federal holiday we took advantage of the �lighter� traffic. We charged for an hour while our SOC (state of charge) reached 99%. While we didn�t plan to stay that long, we enjoyed talking to the "iGenius" in the new "iBuilding".  There was also a Starbucks and restroom on site for us to use.  We left there with our next intended stop in Sherman Oaks, not knowing for sure where we would charge, but would look once we got up there.  I was fully prepared to have my range extender kick in if needed, but I really was trying to do this trip without it.

We found that the local KIA dealership claimed to have an ABB charger, which is the same unit that NRG eVgo uses (yes, CHAdeMO and SAE Combo). We called to see if - 1) the charger exists, which it does, and 2) to see if we could charge, which we were told yes, to come on by.  It was a few miles from the Sherman Oaks location, so off we went.  The charger was blocked, but they immediately moved a car and allowed us to charge.  Unfortunately, the charger was so new, that it hadn�t been provisioned yet, and did not work.  At this point I had 22 miles of range, and 27 miles to the next, known Freedom Station in Hermosa Beach.  So we set off, knowing my range extender would probably kick in.

With some luck, and HEAVY Los Angeles traffic on the 405, we managed to get to Hermosa Beach with 6 miles to spare, and no REx usage.  I drove **83.3 miles on that one charge from Crevier. Once at Hermosa Beach, we managed to find the charger, a nearby bar offering Taco Tuesday, and managed to do all of this while just getting a 30 minute charge. Next stop, the Westminster Shopping Mall ***27 miles away.  We arrived at the mall with no range issues, and were able to charge again for just 30 minutes.  FroYo and a potty stop�and away to Carlsbad for the last stop.

We arrived in Carlsbad, once again hit the Starbucks and charged for only 20 minutes, enough charge to get home.  We were there about 30 minutes, but the charger faulted and stopped early.  We arrived home at just before 10pm.  312 total miles driven, all electric, no REx used, and all charges were free.  We spent a few dollars at Starbucks and for the dinner, but overall, did the whole trip for less than $50, all-inclusive.



Some key points to this trip:


I did not use any climate control until the last leg, there was no need for heating or cooling, but I had to run the defrosters a few times for the last 30 miles.

I ran the entire trip in Eco Pro driving mode.

I preconditioned the car that morning prior to leaving, hoping to warm the batteries before the trip for maximum range.

I purposely did not use the carpool lane. While this might have been necessary in another situation where time was an issue, I preferred to stay in the traffic in order to get maximum range. 

The total time spent portal to portal was 14 hours. I was at the research facility for almost 3 hours, and then we spent almost another 45 minutes to an hour at the Kia dealership talking to the manager about the charger, and looking at their Soul EVs.

Charging added 3 hours, which by using the DC quick charging options, made this a very reasonable trip.  If we had stopped in an ICE for breakfast and dinner, and potty stops, the total stoppage time would have been less, but not significantly, maybe an hour less, overall.
Kris and her "Storm Trooper" Capparis White i3. She's wearing a limited edition i3 Super Bowl jersey that BMW made for this year's game to go along with the i3 commercial that aired during the first quarter. 
My Personal Records:

312 all electric miles in one day (previously 187 in my Active E, which did not have L3 charging)

83.3 all electric miles in one charge (previously 80 miles, in the summer, while hypermiling and drafting behind a truck for 20+ miles)

Cheapest day EVER to drive 312 miles, food and energy included.

*These outlets have two NRG eVgo charging options: level 2 and level 3. The level 2 option has one universal J1772 plug, and the level 3 option has a CHAdeMO (for Nissan Leaf�s, Kia Soul�s, and other Asian brand EVs) as well as a SAE combo (CCS) (for BMW�s, VW eGolf, etc.). This Freedom Station powered by NRG eVgo is part of free fast charging offered by BMW. 

**This car will definitely do better on range with slower speeds, ie: bumper-to-bumper traffic, and city stop-and-go vs full, freeway speeds.

***The mileage between Hermosa Beach and Carlsbad is 87.1 miles.  While we could have easily avoided a stop and used the REx, I would have been forced to charge longer at Hermosa to get a bigger charge, thus not saving any time AND using gasoline.

BMW i Announces New DC Quick Charger and It's a Potential Game Changer

The very first public display of the new BMW i DC quick charger
BMW stole the show today at the start of Plug-in 2014 in San Jose, California by not only announcing a new DC quick charger that will charge an i3 to 80% in 30 minutes, but also by saying the use of these chargers will be free for i3 users through the end of 2015. 

This is a huge step forward for BMW i and the EV movement in general. I have consistently contended that the mass adoption of electric vehicles will hinge on the deployment of rapid charging. Even though the majority of charging will be at a slower rate and overnight, for EVs to really be taken seriously by the masses they need to be capable of refueling in less than an hour while making longer journeys. Tesla and Nissan have already demonstrated that they understand this and have made significant investments in DC quick charge infrastructure, and today's announcement from BMW is proof that BMW also realizes this and appears ready and willing to jump into the DC quick charge game.  
The new BMW i 24kW DC quick charger
The interesting thing about BMW's approach is that they didn't just use existing DCQC equipment. Instead, they took a different approach working with Bosch to create an entirely new type of DCQC that is specifically tailored to suit the needs of their car, the i3. One of the barriers to installing DC quick chargers is the cost of bringing the high voltage service to the location.  By limiting the draw to 24kW's the site won't incur the sometimes-astronomical utility demand fees which can make DC Fast charging cost as much as filling up a car with gas. BMW has worked with utilities to agree on a level of supply which would avoid these high demand charges. 

So if these DC quick chargers only supply 24 kW's that must mean they charge the cars much slower than a conventional 50kW DC quick charger, right? Wrong. This is what I meant about these being tailored for the i3. The i3's relatively small battery can't really utilize a higher rate than 24kW effectively. All DC Quick chargers taper off to a lower charge rate once they get close to fully charging the battery to prevent overcharging and damaging the cells. The i3 only has a usable battery capacity of 18.8kW's so on a 50kW quick charger it only will charge at the full rate for about 10 minutes before it starts ramping down to a lower charge rate. In fact, BMW claims the i3 will charge to 80% in about 25 minutes on a 50kW DC quick charger. On this new 24kW unit, it only takes about 5 minutes longer, charging to 80% SOC in 30 minutes. So for only an extra 5 minute penalty, you get:

1) A low-cost solution for DCQC. BMW will sell the unit to their partners for only $6,548 which is less than half as expensive as the least expensive 50kW CCS DC quick charger made by ABB. "Partners" include BMW dealerships, utilities and municipalities that want to provide this service. BMW hasn't decided on a regular retail cost for the units but they are willing to discuss it with interested parties.
2) The unit is small, measuring 31"(H) x 19" (W) x 12"(D) and only weighs about 125 lbs. It can even be pedestal or wall mounted, unlike any other DCQC on the market.
3) The sites won't have to pay the excessive demand charges for electricity. Instead it will be the regular  electric rate, allowing for a reasonable cost to be assessed for use of the charger. 

Even with all this great news, you'll notice the title reads that this is a "potential" game changer. As good as these units sound, they won't do any good if they aren't installed. It's already been announced that in California the NRG eVgo DC Fast Charging network will deploy a minimum of 100 BMW i3 compatible DC Fast Chargers, but what about the rest of the country? Will BMW step up and prove they are "all in" like Nissan and Tesla have and assist (yes that means subsidize) the deployment of these quick charge stations in other markets? Only time will tell, but I have to say I like what I'm seeing so far. Let's keep the ball rolling BMW.
Specifications for the new DCQC unit

Below is the full press release from BMW:
 
San Jose, CA/Woodcliff Lake, NJ � July 28, 2014� At Plug-In 2014, a conference dedicated to discussing key issues for the long-term success of electric vehicles, BMW of North America launched its BMW i DC Fast Chargers which can charge the BMW i3 all-electric vehicle�s battery up to 80 percent in 30 minutes. A joint development between BMW and Bosch Automotive Service Solutions, BMW i DC Fast Chargers will change the face of public charging as the first compact and affordable DC Combo fast charger. The first BMW i DC Fast Charger will be on display at Plug-In 2014 on July 28 at the San Jose Convention Center. BMW also announced its new ChargeNow DC Fast program in cooperation with NRG eVgo, in which BMW i3 drivers in California can enjoy no cost unlimited 30 minute DC fast charging, at NRG eVgo Freedom Station� sites equipped with DC Combo Fast Charging, through 2015.

Introducing the BMW i DC Fast Charger
Conventional DC fast chargers are about the size of a standard refrigerator, cost tens of thousands of dollars and require a significant amount of electricity. Half the size of a traditional electric vehicle DC charger � measuring 31�H x 19�W x 12�D and weighing approximately 100 pounds � BMW i DC Fast Chargers can be mounted on a wall, a first for electric vehicle DC fast chargers. In addition, BMW i DC Fast Chargers will be priced significantly less than other DC Combo chargers in the market at $6,548 for authorized BMW partners.

�This is a milestone in the development of the DC fast charging infrastructure. With more than five years of real world experience, we understand that a robust network of publicly available DC Combo Fast Chargers is a key part of the mobility of tomorrow,� said Robert Healey, EV Infrastructure Manager, at BMW of North America. �BMW is offering the BMW i DC Fast Charger at an appealing price point, and more manageable size, to make the convenience of DC fast charging more accessible for BMW i3 owners.�

The 24 kW DC Fast Charger feeds the current directly to the vehicle�s battery, resulting in a more efficient and faster charge. BMW i DC Fast Chargers use the SAE Combo 1 connector, the North American automotive industry standard for fast charging; feature a rugged aluminum IP54 enclosure; meet NEMA 3 requirements; and are designed to perform in extreme weather conditions, from -40�F to 185�F. Additionally, the BMW i DC Fast Charger is ChargePoint network-enabled, allowing electric vehicle drivers with the SAE Combo 1 inlet to access the BMW i DC Fast Charger using a ChargePoint or ChargeNow card. Major automakers including BMW, GM, Ford, Chrysler, Daimler, Volkswagen, Audi and Porsche have committed to adopting the SAE Combo 1 inlet for DC charging. The BMW i DC Fast Chargers will be available for BMW i Centers across the U.S. beginning in August.

Introducing ChargeNow DC Fast for BMW i3 Drivers
In keeping with its holistic approach to making DC fast charging more accessible and, in turn, increasing the adoption of electric vehicles, BMW, in cooperation with NRG eVgo, will offer no cost charging to BMW i3 drivers at participating eVgo Freedom Station sites equipped with DC Combo Fast Charging in California through 2015.

Using their ChargeNow cards, BMW i3 drivers will have access to unlimited 30-minute DC fast charging sessions with the ChargeNow DC Fast program. BMW i3 owners can sign up easily for ChargeNow DC Fast at chargenow.com/us. In order to receive the full benefits of the program, BMW i3 drivers must use the ChargeNow card, provided with their BMW i3, to charge the vehicle at least once by December 31, 2014, at a participating eVgo Freedom Station. By doing so, BMW i3 drivers will enjoy continued access to no cost DC charging sessions through the end of 2015. Eligible BMW i3 vehicles must be equipped with the DC Fast Charging option (SAE).

�We�re confident the rapidly-expanding NRG eVgo DC Fast Charging network will provide significant benefits to BMW i3 drivers in California,� continued Mr. Healey. �With the cooperation between ChargePoint and NRG eVgo, ChargeNow DC Fast brings us closer to the reality of one card, one account public charging network interoperability.� eVgo will deploy a minimum of 100 BMW i3 compatible DC Fast Chargers across California to support the ChargeNow DC Fast Program.
�This is a milestone in the development of the DC fast charging infrastructure. With more than five years of real world experience, we understand that a robust network of publicly available DC Combo Fast Chargers is a key part of the mobility of tomorrow,� said Robert Healey, EV Infrastructure Manager, at BMW of North America. �BMW is offering the BMW i DC Fast Charger at an appealing price point, and more manageable size, to make the convenience of DC fast charging more accessible for BMW i3 owners.� - See more at: http://www.longtailpipe.com/2014/07/bmw-shows-smallest-and-lowest-cost-dc.html?utm_source=dlvr.it&utm_medium=facebook#sthash.B9P4jL3V.dpuf
