Some BMW i3 owners are complaining about difficulty charging at home or public AC charging stations. While it's impossible to pinpoint the exact cause, the problem is there, and for the sake of completeness, it's important to note that it doesn't just affect this model, but other brands as well. The first thing to check is that the equipment is fully functional: the problem could be with the charger or the cable. If you can't charge your car at home with AC, try another public charging station with the same AC power source, such as at work or elsewhere. A different issue preventing charging with AC power could be with the home's electrical system or a specific setting on the vehicle. If the problem persists, you might consider replacing the cable with a more efficient product, such as the new, high quality Voldt Compatible BMW i3 Charging Cable, although it's not guaranteed to solve the problem.
