    24V is already an existing system. Manufacturers are looking into 48V++ systems to power all the electrical components simultaneously.

    A 240V battery pack is not much of a problem in the Prius because you don't have to tap into it when installing electrical stuff on the vehicle.

    Like the rest of the people has said.. this is nothing new but the thought is in the right direction.

    Aside from what has been mentioned, some street & legal drag racers (using street legal cars) have an electric clutch attached to their alternators (similar to the one used in aircon compressors) to temporarily disconnect it from the engine.

    Other devices are underdrive pulley systems which makes the accesories (like water pump, alternator, etc) turn slower, hence use less mechanical power from the engine. This is race & street proven to work.

    IMO it would be more economical, for both the consumer and manufacturer and more reliable to run the alternator, power steering and aircon compressor using the engine. Imagine your battery going dead together with your power steering, water pump, etc.

    actually if your battery is dead, you can't start the engine anyway so the same goes for the power steering, waterpump, etc.

    This is especially true if you are driving an automatic tranny car.

    LOL!

    there's always the call TULAK !!! :D same is true that when your belts goes so as the PS, alternator or water pump whatever is the configuration.

    Its not the voltage that kills you, its the current and the frequency.

    Nikola Tesla was running 250,000 volts in between coils using his body.

    The frequency by which the current was being transmitted on the surface of his skin and clothes didn't interfere with his nervous and cardiovascular systems.

    The on-demand action of electrical motors allows conservation of power and active modulation of motorspeeds as required by a specific component.

    A higher capacity alternator does not necessarily mean it has to be bigger or heavier, nor does a better battery have to be assume the same logical progression. Storing unused energy in a battery is still better than losing it to heat and unnecessary motion.

    In fact alternators produce a surplus of power that is wasted.

    "Semi-electric" or active servo power steering systems are mostly stability control mechanisms that ease off the power steering at high speeds creating a tighter driving feeling of the front wheels.

    Electric radiator fans are mostly a function of mechanics in front wheel drive cars. In fact, new cars using a rear-wheel drive layout, still have fans connected to the engine. Why waste excess kinetic energy?

    The beauty of hybrid systems is that there is no need of an alternator. The electric motor IS the alternator.

    So in effect, you're not running the alternator, power-steering and AC off the battery, you're running the power-steering and AC off of the electric motor and the battery.

    As for mechanical fans, a lot of forum members at my other forum are changing over to electric motor radiator fans. They can keep a constant (high) speed even during idling, and are apparently more energy efficient. Even if you have excess kinetic energy at the crank, any added complication will still create drag on the crank, just like pulley driven AC and PS.

    I think that's why CVT transmissions rock... they remove a lot of the drag caused by torque converter systems... this gives them fuel economy comparable to full manuals.

    Ang pagbalik ng comeback...

    wow! nice input tsikoteers.i think ghosthunter is right. at least technology is moving in the right direction.i hope to see the day more horsepower makes it to the wheels.
