These cars draw a lot of power so in 45 minutes you can drop voltage pretty hard more than any 10 amp charger can deal with - I use a 70 amp charger and during a flash the charger will routinely be supplying 30+ amps of power to the car. The issue is that most people are not going to buy a 500 charger, so your other option is hook it up to another car that is running and put some booster cables on it and let that keep it fully powered during the flash.
I can understand that, the closer I get to the end voltage drops.. thanks I will give that a go today..
