Fig. 2 - Brute Force Electrolysis

Nearly all systems installed today use the "Brute Force" method. This approach is most commonly called “Brute Force” because the Electrolyzer (Cell) is connected directly to the power source. This method simply applies the full power available to the Cell to “Rip” apart the water into Hydrogen and Oxygen. Left uncontrolled, electrolysis is a thermal runaway process. Water heats up as an electric current passes through it, in turn drawing more current and heating the water further. Because there is no way to control the power consumption and heat generation it is often problematic for the vehicle's electrical systems and the Electolyzer cell, which can physically melt from excessive heat.
