The trouble in applying extra battery loads to hybrid vehicles might be that the main battery is matched to the car drive mechanism such that maximum economy and speed/weight ratios would not permit

That's true -- the vehicle charges when you are decelerating, as well as when the engine is running. Another heavy load like a high power amp would really put a dent in the power budget! I've always

In a Toyota Prius, the gasoline engine starts automatically to run the generator when the 200v battery potential drops below a certain point. Also, I see no 12v battery in a Prius, so everything that

Dear Rich, That question can't be answered here, now. Not knowing the dynamics of hybrids I can't come up with what kind of amperage would be deleterious. I know there's some overhead for additional

Joe, others, Even a high power amplifier used in SSB service will consume a limited amount of energy due to the low duty cycle of SSB transmissions. Operating from a mobile cannot be compared to for

Two things... First, I run AM on 75m while mobile, so I need a little more than what is drawn during a "normal" SSB transmission. The rig draws 5 or 10A for AM carrier, then the amp is probably pulli

Yes, I too have a couple of 16 x 2SC2879 home brew amps that are flawless at 1,500 watts out running at 14 VDC. But, it will be nice when higher voltage car systems appear, as the available higher vo

Even with a 36/42V system, my guess is that xenon-arc headlights would still need a DC to DC switcher PSU. The Toyota Prius has a 200V, 250A-max battery. Would that make for a handy-dandy, jim dandy

Hello, "250 A-max." Does that mean 250 cold cranking amperes, or 250 Ampere-Hours? In either case, that's not one heckuva lot. Hal W4HBM On Mon, 31 Oct 2005 15:50:58 +0000 Philip de Cadenet <phil@tra
