There's more evidence than that. An unnamed worldwide engineering company has already offered to help Apple build charging stations, Reuters says. Meanwhile, Apple has publicly hired EV charging experts from BMW, Georgia Tech and Google (you'll need to log in to LinkedIn to see them).

If true, the approach is a logical fit for Apple. Part of Tesla's success in EVs comes from its willingness to build a network of high-speed charging stations -- you're more likely to buy a Model S if you know that you can drive it long distances without spending hours waiting for a recharge. Apple may need that same kind of reassurance. And let's not forget that Apple's strategy revolves around controlling as much of the experience as possible. It only makes sense that the company would want optimized charging stations instead of leaving drivers to use generic stations that might not work as effectively.
