I don't think so. An eight hour charger uses a dedicated 220 volt circuit at forty amps. That's nearly 25% of a modern home's total capacity. A half hour charge would require more than 16 times that amount, well beyond nearly any house wiring capacity. And even a couple of hours would fully load any electrical system leaving none left over to run the fridg.
