Re: Inverter to power refrigerator during power outage

I just found out a company offers a product called an EV Power Station: There is a reasonable chance that Nichicon know a thing or two about iMievs [ edit: at least the charrgers and batteries ] , since their name appears on the OBC printed circuit boards, as well as the electrolytic capacitors. Of...

Re: No READY. P1A15 error. Condenser charge timeout.

Tomorrow I want to manually engage main(-) contactor and precharge contactor and see what stable voltage from battery I can see on main battery wires. if is not good idea please tell me. That sounds like a good thing, but be prepared to disconnect quickly, as it seems to me that something is puttin...

Re: Not Charging. Main Inverter Fuse blown

I used diagnostic software and made video of what is going on after turning key to ready position. I left link for video here earlier. Ok, that would do it! Sorry, I somehow missed the video links earlier. It seemed to get to 338 V, which is only 12 V short of the battery voltage of 350 V, and is 9...

Re: Not Charging. Main Inverter Fuse blown

In my case car stops on step 2. Well, if you know that definitely to be the case, great. But how can you tell? From the sound of the contactors? From the trouble code? I think it still could be reaching normal capacitor voltage, sending 12 V to the main positive contactor, and either the coil is op...

Re: Good Luck

You can check on working car - main (+) connects only after getting on condenser full battery voltage. I'm sure @Kiev is quite aware of this. This test would settle the question of whether the capacitor voltage isn't getting high enough, and is therefore not getting powered, or if the main contacto...

Re: Not Charging. Main Inverter Fuse blown

I think I will try to open MCU and look condenser, but I am not sure what exactly to check. Any suggestions? I would think it's not likely to be the capacitor ("condenser" is an ancient term for capacitor); it would have to have *extra* capacitance to cause this problem. [ Edit: Sigh. I c...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Can you describe what is on either side of this 20 amp fuse and which direction the flow is in depending on operating mode and conditions ? I haven't seen the circuit diagrams you guys are referring to. It's basically bare battery positive, after the main positive contactor; see the schematics on t...
