I was just sitting here and it hit me!
The DC load that will be used is Electrolysis. I already have one made with a Stainless Steel plate configuration of 4S2P.
I built it with the intention of installing it on my Blazer to improve the fuel Mileage. Did my homework on varying the amp draw by using a ratio of Sodium Hydroxide and Water.
The amp draw and Gas output is quite low without adding something to increase the conductivity of the water. PWM is normally used in conjunction with this to limit the amp draw.
SO..........with an increase in the concentration of Sodium Hydroxide AND the use of an ESC to turn it up and down, shazam!..........DC load capable of big amp draws.
Big Amps thrown at a Hydrogen unit will normally boil the water in time. Since rarely, 30 minutes at a time will be exceeded with testing, this should do.
The product of Electrolysis is Hydrogen and Oxygen. It breaks down water into it's elements by breaking the covalent bond of the atoms.
Hydroxy gas is VERY explosive. I'll just vent it to the outside.
Ok, now that we have established a good working DC load, we need a good heavy duty amp meter. Something that will accurately measure up to ummmmmmm............let's say 200 amps.
I wonder if I can find one of those digital types that work with a shunt?
