Wiring diagrams of the HV system with most of the Japanese translated manually, and using GIMP to add the text. I could not find any other way to do it with this type of pdf with embedded text within images and retain the quality.

 

Hope it is of some use to you all.

Thanks so much for doing all that work and sharing it with us all.

Many thanks for sharing 🙂

Many thanks for this. Do you have a diagram for the air con system (hybrid series 1) ? cheers

Yes I do, I will have a look and get it posted up but the A/C system is complicated as it is tied into several systems.

Air con system wiring diagram, 10 series hybrid. The Air conditioner amplifier (2 way)  is located to the left of the radio head unit. The Air Conditioner Amplifier is within the heat/vent/distribution control panel below the head unit.

So is there a point on the HV inverter you could connect a DC power supply to to charge the HV battery.  So you could run the aircon all night without firing the engine over? 

Basically no. There is an HV battery charger costing ££££  connecting it involves disconnecting the HV battery cables at the inverter to attach to the charger. A lead also goes to the HV battery ecu.

With the HV leads disconnected from the inverter there is no way to get a/c power to the air-conditioning pump.

Portable aircon unit required!
