12V system testing


The 12V 60Ah LiFePO4 battery pack was mounted on its place with a simple sheet metal frame and a belt. I wanted to test if all the original electronics still work after the original motor was removed. It was great to notice that all lights worked and only the cabin fan did not work. After some research I found out that its power wire was in the motors cable harness and got the fan also working just by connecting it.

Current consumption was measured for the different utilities and the main consumers were found to be the cabin fan taking 16A on full power while the driving lights took 14A.  It's good to know these so I can rate the new fuses and relays correctly. Some changes have already been made on the circuit diagram that was posted earlier. I'll post its updates along the way.

The Corolla eFX is now in a driveable condition with its lights fully functional. The following steps will be wiring the 12V battery pack protection electronics, finishing the heater and mounting the electric brake booster and chargers. After that I'll show the car to the local authorities and hopefully get the car street legal!
