Preventative Measures: See 12V Aux Battery Test in this post
This poll is open to everyone, please indicate if you have experienced a failure of either the On-Board Charrger or DC/DC Converter or the 20A fuse in the MCU or None (no failure).
If possible describe the condition of your 12V Aux battery at the time of the incident such as the age e.g. 4-yr old OEM, or Brand spank new or recently replaced 6 months ago, etc.
Please list the typical amount of battery maintenance that was done, e.g monthly, semi-annual, annual, never, and what procedures were done, such as checking of the fluid level and topping off, any periodic top-up charging with either float or dedicated 12V chargger, cleaning of terminal blocks, etc.
Here's a little form that you can copy and paste into your post and fill in the blanks. If you want to be anonymous you can send me a PM or email and i'll just use your data to tally without any names.

Just looking for clues and trends of why over a dozen charrgers have failed in a somewhat tight time window after 5-6 year of running okay.
1. Year and mileage on your iMiev:
2. OBC failure experience:
3. 12V Battery Condition, Age:
4. 12V Battery Maintenance Frequency and Procedures:
5: Charging history, any incidents of abnormal interruptions such as loss of AC mains, or pulling the AC plug to shut off (as opposed to pressing the J1772 button or automatic shutoff by the car):
