My14Energi Posted September 6, 2017 at 05:43 PM Report Share Posted September 6, 2017 at 05:43 PM On a normal car a power inverter can be hooked up to +/- terminals to allow 110v options. On our cars to the underhood terminals connect to the HVB or the smaller 12v battery? Once the car is started do those same underhood terminals get power from HVB? How would a power inverter work for our cars? Quote Link to comment Share on other sites More sharing options...
murphy Posted September 6, 2017 at 06:40 PM Report Share Posted September 6, 2017 at 06:40 PM Have you looked in the back seat? The car has a built in inverter that is good for 150 watts I think. Quote Link to comment Share on other sites More sharing options...
My14Energi Posted September 6, 2017 at 09:42 PM Author Report Share Posted September 6, 2017 at 09:42 PM (edited) Yep, 150 is pretty low. Thats pretty much there to keep a laptop plugged in, not good for much else. Same question as the other thread, with the power inverter connected it gets power and shows 14.2V, where is it getting that from....the HVB or smaller 12V. Once the car is running shouldnt it be the HVB? Edited September 6, 2017 at 09:55 PM by My14Energi Quote Link to comment Share on other sites More sharing options...
murphy Posted September 7, 2017 at 12:19 AM Report Share Posted September 7, 2017 at 12:19 AM It is wired to the 12 volt battery. It's 14.2 volts because the DC-DC converter is charging the 12 volt battery. Quote Link to comment Share on other sites More sharing options...
My14Energi Posted September 7, 2017 at 02:01 AM Author Report Share Posted September 7, 2017 at 02:01 AM (edited) So the 12V does receive a charge from the HVB then? I hooked up the power inverter to the underhood connections with the car running in hybrid mode, HVB depleted as far EV only charge, and obviously not plugged in. The power inverter showed a reading of 14.2V, so without the car plugged into the wall the 12V system was getting a charge from somewhere. With the ICE running there is power going back into the "system" somehow anf maintaining a charge on the 12V system.

murphy Posted September 7, 2017 at 10:04 AM Report Share Posted September 7, 2017 at 10:04 AM The DC to DC converter does the same job as an alternator in a standard car. It gets power from the HVB if the engine is not running or from one of the MGs (motor/generator) if the engine is running. Quote Link to comment Share on other sites More sharing options...
My14Energi Posted September 7, 2017 at 04:30 PM Author Report Share Posted September 7, 2017 at 04:30 PM Thus the HVB never really drains to zero and always maintains some level of charge and therefore always keeping a charge on the 12V system, if the HVB gets low the ICE kicks on to charge back up the HVB only. It all makes sense now. Quote Link to comment Share on other sites More sharing options...
My14Energi Posted September 12, 2017 at 06:01 PM Author Report Share Posted September 12, 2017 at 06:01 PM The power inverter has worked fantastic while no power due to Irma. Have had the car "on" for over 24 hours straight. Works like a charm. jj2me 1 Quote Link to comment Share on other sites More sharing options...

What are you running with it? Quote Link to comment Share on other sites More sharing options...
