Thanks, you answered all the question very clearly. I still need some clarification on #7. Most industrial monitoring and alarm systems prioritize faults. A warning is a malfunction that does not stop the process. A fault will stop some action. Most ICE cars have a Engine Check Light. When the Check Engine Light illuminates, the car will usually continue to operate; however, an error code is stored in the computer. The same applies to the "idiot lights" on a car. An ICE car shuts down if a major fault occurs. With an EV inverter, it is possible for an IGBT to overheat and the car could be put in a lower performance mode but continue to operate. The car could illuminate a warning light is this case. In addition, an EV inverter could blow an IGBT or have a shutdown temperature setting. Since the auxiliary battery is still operational, a fault light could illuminate. Does an EV have two lights and does it prioritize malfunctions?

This position typically does the same as in an ICE: it does not power up the drivetrain, it only enables some 12V loads such as radio, lights and cig lighter to name a few, but the aux battery is not charged and extended time spent in ACC mode will run down the aux battery. You could modify the ACC mode to engage a relay that powers a battery charger (off the main pack) to recharge the aux battery. You shift the risk from running down the aux to the main pack. AC or heater are typically not enabled in ACC In case I mis-interpreted your question: if you want to know if the main pack can be charged in ACC mode then yes - main pack charging is typically possible in ALL vehicle modes except when "Ready to drive". Even if the car is off, if you plug in the charger it will typically power up enough of the car to charge the main pack and also keep the aux battery maintained. Some cars allow heating/cooling of the car (even remotely controlled) and this is very useful when already plugged in to charge the main pack. Car does not need to be in ACC mode to do this for the production EVs that have this feature. Conversions typically need to be "Ready" before allowing heating or A/C. (3) Since the inverter is not powered in ACC mode, you do not depress the brake. In fact, *not* braking while pushing the Power button is how you put the car in ACC mode. If you brake and push Power, then the car starts to "Ready". (4) I don't know for sure, it makes no sense to apply 12V to the inverter when it is not used, so I expect not. (5) No (6) Yes (7) What do you mean separately? The software runs through a list of checks. Anything that does not check out and is worthy of reporting gets reported, so the reports are typically coming in one after the other but due to the speed of the software, it may appear to the human eye as if they all happen at the same time. Most reports are not for immediate diagnosis anyway, just to give a go/nogo indication and then you can connect a tool to browse through the reported issue and read them one by one and deal with each one.

As I have seen in past posting the subject was very quickly changed to another subject. In this case, a heater burn up issue for the Think City Heater. Please do not do this again. Please, respect the post. Thanks. I will try again with very specific questions. (1) How do you put an EV in the auxiliaries only position? Does it have an ACC position as on older ICE car with a key? (2) When in the ACC only position, can the battery charger be energized? Can the AC or heater be energized? (3) Do you need to have the brake pedal depressed to energize the inverter? I think this is required to depress the START button. (4) Is logic power (not HV) applied to the inverter if the car is in the ACC position. (5) Is the HV/12VDC converter energized in the ACC position? (6) Is the HV/12VDC converter energized when the car is charging? (7) During start up, does the car report warnings and faults separately? -------------- next part -------------- An HTML attachment was scrubbed...
