It looks like a mess, but I will clean up the appearance by routing the wires in split loom tubing. Once the component placement is finalized, the plywood will be replaced with aluminum panels.

12 Volt Wiring
I need to tie into a number of the car’s 12 volt signals. The controller needs a 12 volt power source that is switched at the ignition switch with the key. The controller makes use of the brake and reverse signals to cut or reduce power output to the motor. The controller can also generate the proper signal to drive the stock tachometer in the instrument cluster. I traced out the signals in my service manual.

In my Honda Hybrid, if the 12 V battery is discharged (e.g. I left the head lights on), car is done. Need a jump even if the 144 V system is fully charged.
ReplyDeleteRufus.
Same situation here, except I will use a DC-DC converter to charge the 12 V battery off of the main pack, but I would need to figure out the fault that drained the battery or risk draining the main pack.
DeleteNice detailed pictures on your blog and conversion. Are you going to connect the DC-DC converter so that it is always on?
ReplyDeleteHi,Ken. Always on is the plan for now. I will disconnect it if the car sits for a time, but I haven't come up with a way to automatically turn the DC-DC on and off.
