NY International Auto Show: One on One Interview With BMW's EV Boss

BMW i North American Product & Operations Manager, Jose Guerrero
I had the opportunity to sit down with BMW NA’s top man when it comes to electric vehicles, Jose Guerrero at this year’s New York International Auto Show. Guerrero is BMW i’s North American Product & Operations Manager, and has been working in BMW’s electric vehicle programs since the ActiveE pilot program began in 2011.

Just before we started the interview, it was announced that the BMW i3 was named the inaugural winner of the World Urban Car Award, so I asked Guerrero for his thoughts on the i3 winning yet another award.

“I think it’s a testament to the car. Even though we’re making incremental improvements, like software updates and offering a moonroof, the only real dramatic improvement we’ve made is the addition of the 94 Ah battery. That said, the car is still remaining relevant with the backdrop of increased competition in this segment.  So, to see the continued accolades for a car that launched over three years ago is a good sign, and rewarding to us. But we’re not stopping; we’re continuing with product improvements on a fairly short basis, verses the traditional BMWs.”

There isn’t much more news to report on the i3 & i8 at NYIAS this year. The i3 is scheduled for a minor refresh in 2018, but BMW isn’t publically commenting on that yet. It’s been widely speculated that in addition to the refresh, a new i3 Sport model will be offered, and many spy photographs of what appears to be this version have already been posted online. I wouldn’t expect BMW to comment on this until the formal introduction of the 2018 i3, which will likely happen at the Frankfurt Motor Show in September.
 
BMW i & BMW iPerformance vehicles are side by side at NYIAS
We then moved to the topic of BMW iPerformance vehicles, which have a prominent placement on this year’s show floor at NYIAS. BMW now offers four plug-in hybrid iPerformance vehicles, the X5-40e, 740e, 330e and the just-introduced 530e.  Guerrero said they are selling very well, and the dealers are selling them as quickly as they come in. He added that the supply is going to increase as the year goes on, but has faith that the dealers will continue to sell them nearly as quickly as they get them because the demand is there.

I then mentioned that some EV enthusiasts are critical of PHEVs that have low all-electric ranges, like the iPerformance line offers, and asked for his thoughts on that.

“The market for iPerformance is still in the early stages, and the success we’re having is really taking place at the dealership level. With BMW i, we had to work harder to find the customers and cultivate sales for the i3. With iPerformance vehicles, people are coming in off the street not even knowing about our plug-in offerings. Yet they are being converted because of the driving experience and the overall cost of ownership. There’s a job for BMW i electric vehicles, and there’s a job for BMW iPerformance plug-in hybrid vehicles. Not everybody is ready today for a fully electric vehicle, even if his or her driving profile matches what the i3 offers. We understand that this switch to EVs won’t happen overnight. We need to get people used to plugging in their cars and experiencing the benefits of electric drive first. That’s the job of iPerformance vehicles, it’s really converting a lot of people to the plug. That experience may lead them to purchase a longer range PHEV the next time around, or it may lead them to an all-electric car. Not everybody is ready for an all-electric vehicle at this point. I am (Guerrero has been driving an i3 since 2014), I know you are (referring to me), but for many who aren’t, iPerformance vehicles are the sweet spot.“
Guerrero speaking at an unidentified BMW event 
I then asked him if BMW of North America is ever going to participate in the i3 Battery Retrofit Program that BMW AG announced last year. The program is currently only available in a select few European countries, and BMW of North America hasn’t commented on whether they will ever offer a battery upgrade program. I think I was able to get (kind of) the first official confirmation that BMW of North America will offer a version of a battery upgrade/retrofit program at some point in the future, and that they are already testing internal fleets of retrofitted i3s.

“Absolutely. Even though we made the decision to not offer this option today, we’re still conducting our own internal study with a fleet of i3s that we’re retrofitting with battery upgrades to learn from and study for the US-specific group. Even though we don’t have a consumer offering, internally we have fleets running around learning the benefits and challenges. So we’re not stopping, just because we didn’t initially offer it. As long as there is a viable consumer program that people would buy, of course we will offer it. There’s also a sustainability side to this. There’s stationary energy storage, there’s the smart home and solar story that are tied to the ecosystem with home energy storage. We know even if there isn’t a car-to-car alone business case for upgrade, it works from the whole 360-degree sustainability model.  We are looking at this holistically; we want to say to the customer: Here it is; solar, battery for energy storage, the Internet of Things, and your electric car. This is how it all works.”


At this point my allotted interview time was coming to an end so I asked Guerrero if there was anything he’d like to add to our discussion.


"First and foremost, I’d like to say we’re listening to our customers. We’re taking in all of the feedback we’re getting from our current plug-in customers and our dealers, and we’re learning from that. Things like the numeric state of charge gauge. Our customers asked for it and we added it. Lesson learned. The next generation of electric vehicles we offer will benefit from all of the feedback we’re getting today. We’re going to continue to improve and innovate. But we realize the future is always changing, whether it be inductive charging, or high speed DC fast charging we will be there and continue to innovate. However, we will still rely on customer feedback, so we always want to keep that conversation alive.”

Product Review: ClipperCreek HCS-40p EVSE

My i3 charging from the HSC-40p. You can see my older ClipperCreek CS-40 all the way on the left.
When it comes to electric vehicle charging equipment, there’s certainly no shortage of choices. Even though it’s a relatively new market, there are dozens of manufacturers selling products that allow owners to safely and conveniently charge their electric cars. Although this equipment is commonly referred to as a "charger" or "wallbox", the proper term is actually EVSE, which stands for Electric Vehicle Supply Equipment. 

These devices don't actually charge the car; they provide the electricity to do so. That's because the actual charging equipment is built into the car. The EVSE's purpose is to safely deliver the correct amount of electricity to the onboard charging equipment. 

Now that electric cars are beginning to gain momentum in the marketplace, there are a lot of companies jockeying to get a market share of the EVSE business. The vast majority of these companies have been manufacturing and selling EVSEs for less than six years. However, there is one EVSE manufacturer that has more experience than any other company, with roots that go back into the early 1990s, as well as supplying the home charging equipment for the Tesla Roadster. ClipperCreek, has been making EV charging equipment for over twenty years now, and manufactures all of their products in the USA.

I’ve been using ClipperCreek products to charge my electric cars since 2009, as BMW choose ClipperCreek as their partner to provide the charging equipment for the MINI-E Trial Lease Program.  I’ve never had any problems with any of my ClipperCreek equipment and I still use my original CS-40 EVSE that came with my MINI-E.

However, I also have a version of the latest generation of EVSEs from ClipperCreek, an HCS-40p.  The HCS-40 & the HCS 40p can supply 32 amps at 240v, and deliver up to 7.7kW to the vehicle.  The only EVs currently on sale that can accept more than 7.7kW at 240v are the Tesla Models S & X, and the Mercedes B250e (which uses a Tesla-made onboard charger). So the HCS-40 line of EVSEs is more than powerful enough for the vast majority of today’s electric vehicles. 

For instance, my 2014 BMW i3 can only accept up to 7.2kW, and the rest of BMW’s line of PHEVs, including the i8, the X5-40e, the 330e, the 530e and the 740e, are all limited to a maximum of charging at 3.7kW. This is because plug in hybrid electric vehicles (PHEVs) have smaller batteries than full electric cars do, and thus charge quicker and don’t require such high speed charging.
ClipperCreek uses high quality connectors with a rubberized grip for added comfort when plugging in.
However, if you do want more power, for instance to future-proof your garage, ClipperCreek has you covered. They also sell the HCS-50 & HCS-50p, which both deliver 40amps of power, which translates to a maximum of 9.6kW. The HCS-60 steps up the delivery to 48 amps and a full 11.5kW. For the ultimate in home EV charging, the CS-100 can deliver 80 amps to the vehicle, which is a whopping 19.2kW.  This power delivery rivals the speed that some of the lower-powered DC Fast chargers, but currently only Tesla vehicles can accept such high a level of power from a level 2, 240v EVSE. I believe that's going to change in the coming years, and many EVs will come standard with higher power level 2 charging capabilities of at least 9.6kW.

I received my HCS-40p about a year ago and it’s lived up to the reputation that past ClipperCreek products have earned.  Made from airline-grade plastics they are probably the toughest EVSEs on the market. There’s even a video of ClipperCreek employees beating an HCS-40 with a baseball bat, and the bat broke before the station did:


The HCS line comes in both hard-wired and plug-in models. The plug-in offerings are distinguishable by the “p” at the end of the model name. If it has the “p”, than it’s the plug in version. You can order the plug-in versions with either a NEMA 14-50 or NEMA 6-50 plug.  Therefore, you can have your electrician install the 240v you choose before you even buy the EVSE. 
Two screws & it's done!


Personally I prefer having the plug in option, which is why I got the HCS-40p. It’s a little more expensive, ($589 compared to $565 for the HSC-40) but it offers the flexibility of easy installation – you simply screw it into the wall and plug it in. Having the plug also means it’s not permanently installed in one place.  If the need arises, you can unplug it, remove the two screws and relocate it. This can also work very well if you need to take the unit to a second location, like a summer house. All you need to do is install the outlet in the second location and just take the unit there when you need to.



I test electric vehicle charging equipment and review new products, so you can see how the HCS-40 compares in size to many other EVSE options available today in the picture below. It is one of the larger packages available today, and the body of the unit is used for cable management, you simply wrap the cable around it. There is a separate connector holster included that you can locate where it’s most convenient, as well as a lock and key so you can deter someone from unplugging your car.
My "Power Wall"

ClipperCreek has an extensive list of electric vehicle charging equipment and probably offer more options than any other company. All of their Level 2, 240v EVSEs come standard with a 25 foot cable, which is optional on the products of many of their competitors. Many EVSE purchasers don't consider the cable length when they buy one. I think some may assume they all are a standard length, but that's not true. Some EVSEs come standard with a 15 or 18 foot cable, and that may come up short in certain circumstances. With a standard 25 foot cable, you are pretty much assured you can reach any point in your garage, and even outside the garage if you park close enough. 

Note: I received the HCS-40p from ClipperCreek for free for the purpose of testing, feedback and product review. No other compensation was made.
