That's actually a very simple circuit. It's a variation of the capacitive power supply commonly used in appliance controls. It's more or less just a motor run capacitor in series with the AC line and a bridge rectifier connected to the output along with a charge control circuit. Add a light dimmer in series and it becomes an effective desulfator.

However, capacitors large enough to supply enough current for EV batteries would be too expensive. A switching power supply or a series inductor would be a better choice.
