BMW throws a cord to i3 EV

On the first day, BMW said let there be charging stations. And there were. And they were good … also, cheap. Today BMW unveiled two new programs to help get more EVs on the road. Not only has BMW partnered with automotive parts supplier Bosch to produce a game-changing new fast charger, BMW i3 EV purchasers will now have access to a year of fast charging from the nation’s largest private networks of fast chargers. It turns out that ze’ Germans are just as serious about electricity as everything else.

BMW had a question: Why were DC fast chargers so expensive? After all, while a DC fast charger is the size of a refrigerator and costs $30,000, the part that makes it work is just an AC to DC converter; BMW already makes those for its cars for less than a $1,000. So BMW brought this question to Bosch. After much thinking and tinkering, Bosch and BMW devised something rather clever.

Not only is the actual hardware only a third as expensive as previous chargers, it is significantly cheaper to install. What the two German engineering giants created is the i DC 24KWh fast charger. It’s the size of a piece of carry-on luggage and costs just $6,548. Not only is the actual hardware only a third as expensive as previous chargers, it is significantly cheaper to install.

Thanks to its small size, 100-pound weight, and lower demand for electrical current, it won’t require nearly the same amount of infrastructure as current fast chargers. That is a big deal, considering a $30,000 fast charger can cost anywhere from $20,000 to a trouser-troubling $70,000 to install.

Perhaps the best part of this program is that the i DC chargers won’t be exclusive to BMW. The chargers use the SAE Combo 1 inlet, which is already in use by GM and VW, and looks to be the emerging industry standard for chargers.BMW made clear to Digital Trends that it wants to see as many chargers out there as possible. And as such, wants to deliver a product with as broad a use as possible. In fact Bosch and BMW will be happy to sell these chargers to any interested party, including private companies or local governments.

BMW is also going beyond simply adding chargers, to giving expanded charging access to its customers. The new ChargeNow DC Fast program marks both a major expansion of BMW’s existing ChargeNow network, it is also a step toward the goal of interoperability among charging networks.

The core of the expansion is unlimited 30-minute fast charging through 2015 for BMW i3 customers. This guarantee will be honored not just at BMW’s previous partner ChargePoint but also at NRG eVgo’s new Freedom Stations. BMW hopes that this program will help create the “premium” experience that BMW customers expect, by reducing complexity and anxiety over charging. There is another important factor for i3 drivers: cost. The i3 is supposed to draw in middle-class customers who are hoping not just to save the polar bears, but also their bank accounts – and fast charging isn’t cheap. Thanks to the 480 volts of juice needed to run a fast charger, a 30-minute session can cost as much as $4.95. That may not rival gas prices, but it shouldn’t be ignored either, particularly if used frequently.

In that sense, BMW may not draw in many customers who weren’t already interested in an EV, but they could help lure away customers from other EV makers by reducing the cost of ownership. And even if that doesn’t happen BMW has helped set the stage for more interoperability of EV infrastructure.
