There are mechanics for recharging powers - but they only appear at Paragon Tier and Epic Tier, via the Paragon Path or your Epic Destiny. They don't follow a consistent mechanic, and for some, you need to look "close" to see it. Some require action points, others are inherent to the power.
Some also come through magical items (Veterans Armor).
Of course, it now seems desirable for some to have such mechanics available beginning at the Heroic Tier and be integrated in the core concept of power. But I am not yet convinced that this would be necessary. I certainly had fights where I would have liked a particular power back, but I've not experienced enough "grind" to make me feel that this is required.
