charging without any heat?

Yes.

Yes.
When using batteries and such, you distinguish between Energy and Power. Energy is given in Joules, or Watts*time and Power / Energy Flux in Watts or Joules/time.
In your example, charging the battery for 1 hour at 200W will give it 200Wh (or 720kJ). You can discharge this Energy at any wattage you want. x W/200 Wh gives you the amount of time that drain can be sustained.
