I will check the 12 V battery and the 14.6 V in the ready state , but i think it must be in good condition, as it drives the other electic parts such as, e-windows ...
The EVSE is checked with other EV and it works fine.
The main (tracking) battery is not empty ( 25 km is available) , and the car can be driven without any problem. I can go for a ChaDemo charger and this helps to know that OBC is ok or not.
Today i opened the metal cover of the drive system and all the boxes looked nice, but one of them must be wrong. I know which is the OBC box but it is sealed nicely and i was not daring enough to open it. Before open it what to do for safety. ( inside of the box the 360 V is there).
The MCU ( the motor control unit ?) is just right on the top of the motor? If the car funtioning perfectly can this MCU 20 A fuse blown?
Opening any box what is the best way to make a perfect insulation after fixing the problem? ( if i do it wrong it may cause serius problems to the electronics).
It will not be easy to find a new capacitors if this will be the problem, (maybe e bay?)

Before you go too much further measure the AC voltage at the property where the EVSE is installed. (I assume your house ?)
These cars will not charge if the AC voltage is above about 247 volts, which I consider to be a design flaw. I don't know about where you are but here in the UK AC mains voltage is allowed to go as high as 252 volts and still be within specification and this will prevent the car charging.
I found this the hard way when our usually 235 volts AC went up to 249 volts for one day last year during very bad winter weather, (some sort of national grid supply problem) and the car would refuse to charge with the same symptoms you report - appearing to start charging at first including the fan running but aborting after a few seconds.
I thought the on board charger was faulty at first but after finding fault codes logged in the OBC that reported the mains AC voltage was too high I realised what was going on. I was able to start a charge by turning on the electric shower in the house to pull the AC voltage down slightly!
The following day the voltage was back to normal and the car has charged without problems since.
It's probably not your issue but it's something easy to rule out first. If your AC voltage is on the high side, try driving to a Level 2 charger at another location and trying the car there.
Another thing I would check is to make sure the gear lever is properly engaging in park mode and doesn't feel "springy". If it doesn't fully engage in park this will cause the P to flash on the dashboard when the key is on and the car also will not charge. I've had that problem before too! Solved by lubricating the linkages on the left hand side of the gearbox that go to the bowden cable for the gear lever. Also probably not your issue but worth ruling out.
