I am very sorry this happened to you and I'm sure it is very frightening when it happens. This kind of event happens in almost every EV in very small numbers. It also happens in gas cars, but people don't talk about it much.
There have been reports from European and American vehicle owners that have had this happen to their e-Golf and VW has replaced the main "Power Electronics (JX1)".
After the repair is complete, you should file a complaint with NHTSA here: http://www.safercar.gov/Vehicle+Owners
and select "File A Vehicle Complaint Now". That is the only way to push manufacturers to issue recalls for this kind of issue.
