BMW introduced its Smart Charging App on Monday that helps customers save money on charging their cars at home by identifying the hours during which electricity is cheapest. BMW says the app has the potential to save customers nearly $400 annually.
 The app is available for Android and Apple devices, and it’s integrated into the iRemote App, which sends drivers information about vehicle temperature, status, charging times and related costs on their i3.
 For this first phase, the app will be offered only to BMW’s Electronauts. That’s the company’s cute name for its i3 early adopter program, which started in 2012. The app uses a direct connection to a national energy-rate database, hosted by a BMW partner Genability. BMW says the app allows drivers to adjust their charging strategy days and even weeks in advance.
 We drove the i3 late last year, and we liked that it was open, airy and spunky on the road. Check out the review here.
