This blog documents the restoration, and conversion, of a 1965 Humber (Singer) Vogue to a fully electric vehicle. The intention is to power the electric car (EV) with an 11kW(modified), 3 phase industrial AC motor, controlled by an industry standard Variable Speed Drive (VSD) or Inverter. To be able to produce the 400 volts phase to phase the VSD will need about 600 VDC of batteries. A big thanks to the contributors on the AEVA forum: http://forums.aeva.asn.au/forums/

Basic Electrical Diagram and Layout

I notice that I haven't described anywhere how the electrical system in the car works.
Here is a basic diagram.
Essentially a bank of batteries supplies 600 Volts DC to the controller, that "chops" the DC up to look enough like 3 Phase AC (the type of AC used in factories) to run the 3 Phase AC Induction Motor.

The controller "*speed" signal comes from an accelerator pedal exactly the same as used on "fly by wire" cars like the Holden Astra, Audi, VW Golf etc. (*Actually the pedal controls torque.)

This diagram shows Lithium Iron Phosphate battery packs. There are 12 packs of 50Volts (shown in diagram as 48V) with 20AH capacity - that makes around a 12kW/h pack.

The motor is coupled directly to the tail-shaft. There is no clutch or gearbox.


Here is the proposed layout of these components in the car.
This will most likely change a bit once I have the existing Engine and gearbox out and can better measure where stuff can go. (Updated to show Lithium Batteries.)

Hi Johny,

Your Vogue is great. Is your dc-dc converter meanwell? If so, I would like to know its capacity and performance.

Best regards.

Hi Murat.
My DC to DC are two regular 240 VAC to 13.6 VDC power supplies. See the DC-DC label for details.
