Alan Cocconi's AC Propulsion',EV- conversion CRX used inverted 3-phase AC current in his car,from 28, 12-volt spiral-wound batteries.The inverter was 98% efficient.His CRX maintained full"performance" right up to battery depletion threshold.On-board "look-up" real time diagnostics allowed state-of-charge and remaining range display capability.-------------At$ 70,000(US) for the converted CRX,it was pretty serious electronics.He's the guy that designed the initial controller for the GM Impact.
