What are the recharge times for a 2021 Toyota Camry Hybrid at Levels 1 and 2

I am not aware that Camry has a plug in hybrid

The battery is charged when the car goes down a hill or when you stop. How fast the battery charges would depend on your driving conditions.

You don't charge it, since it is not a plug-in hybrid. It charges itself. It does this mostly while driving since the engine is more efficient when it generates two to three times as much power as kit needs for cruising. Yes, it does charge the battery while braking, but it uses more charge getting back to the same speed. So it never *gains* charge this way. This is possibly the most common myth about hybrids.
