A bolt on hybred system

This could prove interesting for improved performance and economy in a motor home, if it works and is affordable that is.

Next time when "you" see the water pump next to the tank. Look at the electric motor. It's about 1.5 hp and think about the size compared to the motor bolted onto the engine....

I reckon is good for about 4-5hp continuous.

Not designed for continuous max output, wound at a low voltage 3 phase and driven by a VFD. Max speed is controlled by supply voltage, torque by the frequency shift always ahead of the motor speed (at least that is how I understand it) so the max torque is limited to how much heat can be removed from the electric motor.
My impression was more to do with the drive belt size, how much torque could that handle? The beauty of the whole concept is the same unit is the starter motor, alternator, regen braking retarder and drive assist.
Say it could handle 50hp for 5 mins, 50hp added to the engines peak output while climbing a hill would be the difference between holding the higher gear or needing to drop down to a lower gear and crawling up the hill. The same 50hp in the form of a crankshaft load would assist compression braking so the use of the foot brake would be reduced while the harvested energy would be recharging the batteries rather than creating heat in the brakes. The torque from stationary would mean the engine could be at a very low idle or stopped when not moving yet start and drive off the mark much quicker than the engine alone could achieve as the engine has not reached it peak torque, yet the electric motor has peak torque from the moment it starts to turn.

A system that could couple the potential of the drive motor to the crankshaft is the key, my preference would be direct coupling as belt wear and whip would be eliminated.
