Yea, that's not a hybrid, it's a full electric car. Hybrids primarily recharge from the gas engine, which acts like a generator. Regenerative braking helps, but doesn't generate nearly as much electricity as the engine. At least that's how our Prius works. Another advantage of regenerative braking is that the brake pads don't get worn down nearly as much as normal, since the kinetic energy that would normally be converted to heat via friction is getting diverted to spinning an electric motor.
