VF8 Battery NOT Charging
I just received delivery on Sunday, 5/7. I tried charging for the first time last night using a level II charger that I know for certain works because I charged my wife’s EV earlier in the day and it charged just fine. I plugged in my level II charger at night and the battery was at 46%. The car charged over night. When I woke up today, I was shocked and upset to find that the car charged only 4% (it got to 50%) after 8 hours of charging. The 8 hours of level II charging should have fully charged the car. And, the Vinfast charge port light was flashing green when I plugged in, meaning there were no issues. Has anyone else experienced the same issue How? How am I supposed to use an EV car ( that I need to go to and from work!) that charges at this ridiculously slow rate?! I called customer service this morning and I was told the Service Center will call me to schedule a time to bring it in. So far, this has been a very bad first impression, Vinfast! I hope you turn it around quickly, or you won’t survive.

I am curious since I am about to put in the lvl2 charger Friday. When you plugged in go to the charging screen then tap the cord tab and that will show the amps it is using. I am curious if we need to manually adjust that when we go to a lvl2 charger. My normal amount for 110 outlet is max 13 amps. So next time you plug in check the screen see if you can adjust the amps it is using

Ever since I got my VF8 in March, I always had problems with charging at home. I am using the 240 V outlet that was made for the electric dryer in the garage. At times, the car charged right away and reached 100% over night at around 7% per hour. That was with 30A setting. At other times, it would not start no matter how many times I unplugged and plugged back in. The charging could stop anytime or wouldn’t start until some random time during the night. In short, it had always been a “hit or miss”.
Andrew, the technician, took the car back to Irvine to work on and at times, thought to have found a solution in software but the problem came back. The odd thing is that it charged fine at the Service Center in Irvine and even at Andrew’s home in Temecula.
One afternoon, the car was charging for about 45 minutes but it stopped. The flashing green light on at the charging port turned solid green. I just happened to be there when that happened and by chance, I noticed that the blue light on the VF portable charger was now amber. The solid green on the car would turn off and the amber on the charger would then come back to blue and of course by this time, the car already stopped charging with no fault reported. This made me think that the charging stoppage is not caused by the car but rather, by the charger itself. My breaker for this circuit is 30A.
When I set the current for the car to expect 30A, I thought if there were any problem, the breaker would trip. But the fact that my breaker has never tripped somewhat shifts my attention to the charger.
I then tried to adjust the current to 19A which is less than the 80% safety mark of 24A that a 30A-rated breaker has. And guess what, it’s been over a week now that my car charges perfectly without any problem previously seen!
So far, we understand that some owners in California have this charging issue while the owners in Vietnam don’t have any problem at all! And of course, the problem is never seen at charging stations nor at Service Centers. I believe this only shows up at homes that have 30A (or less) breakers whereas newer homes that have 50A breakers have not reported similar problem.
In short, if you are having problems with charging at home using the VF portable charger, adjust down your charging current to see if that helps. If it does, slowly adjust up the current but never more than 80% of your rated breaker’s amperage. The higher the charging current is, the shorter the time to full charge. But find a comfortable number that will shorten your charge time while ensuring the charging process goes as smoothly as it should.

The problem is the car and software.
I use the VinFast charger to charge my Tesla (I have the adaptor) since we currently only have 1 level 2 charge port in the garage. My Tesla never fails to charge with the Vinfast charger however the Vinfast will not charge. I have adjusted the Amps for the VinFast from 32 to 30 to 28 to 24. to be honest, nothing works.
I have tried 2 generic chargers (bought and returned) with the same results. The Tesla works with any charger while the VinFast wont charge with any charger.
The VinFast even fails at charging stations, Electrify America and ChargePoint.
7 months with no solution, I think e have been more than patient and should expect fair compensation.
After the big software upgrade the charging did improve for some time and I actually saw better battery performance but now we are back to charge fails every 10 minutes.
If I can’t charge the car and if the basic safety functions dont work, what in the world did I get tricked into?
