It seems BMW has been busy developing new ways to charge your i3 or i8 lately. A few months ago I posted information on BMWs new low cost DC Fast charger and I just got word from an i3 owner in California that the first one is already up and will soon be ready for use at Crevier BMW in Santa Ana, California.
The latest news out of Munich is BMW's "Light the Charge" program. BMW has developed LED streetlights that also have built in charging stations. They already have a couple of them in place outside their Munich headquarters, and will soon begin installing them around the city of Munich for a pilot program. The units will be networked and allow the customer to pay with a credit card or by swiping an RFID card from a partner charging network provider. In the US, BMW's charging partner for ChargeNow is ChargePoint.

The obvious issue with adding charging stations to light poles is available capacity. Will the utilities have to pull new wires to accommodate the added demand or are they already over sized and can handle the additional load? In Europe the standard electrical supply is 230v so there is already more available power than we have here in the US where the basic household supply is 120v. I'd imagine most light poles here are typically 120v, but I'm not 100% certain about that. Pulling new wires and upgrading the lights could prove very costly, more so than even installing stand along charging stations, but I could see how using these on new light pole installations would work.
Besides street side parking, I could also see how this approach would work well for large parking lots. Instead of having the charging stations all located in one place, which typically is a desirable location close to the buildings, they could be scattered all over the parking area, and each light pole could service the four parking spaces surrounding it.
Whether this idea comes to fruition and becomes a reality beyond the pilot program is unknown at this time, but I like that BMW is really giving thought to how they can improve public charging for their customers. The maturation of the public charging infrastructure is crucial for mass electric vehicle adoption, and I hope BMW continues to explore new ways to help make it ubiquitous.
