This blog documents the restoration, and conversion, of a 1965 Humber (Singer) Vogue to a fully electric vehicle. The Vogue will be powered by 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:

DC-DC Relay

As mentioned many posts ago in this blog, I have two Switch Mode Power Supplies (DC-DC converters) that will supply up to 40 Amps for the 12 V systems in the car. I do not want to connect them directly to the little 9 AH, 12 V battery because if the car is left idle for some time the DC-DCs will drain the 12 V battery.
So there will be a relay in between the DC-DCs and the 12 V Battery. The relay will turn on when the high voltage system is energised.

A Tyco 150 A relay seems to be a good overkill. Seriously - I had it - and it gives me some convenient 6 mm terminal posts to connect things to. The coil doesn't draw any more current than one of those automotive Narva (or similar) 70 A relays.

The two purple wires go to the coil.

I will try to get it mounted and partially wired tonight.
