You send the battery truck out. It looks kinda like a tow truck towing a huge battery. It can charge 8 cars at a time. It takes 30 minutes to get 8 cars up to 3kWh. So a 30 vehicle stack up would take 2 hours to clear with just one battery truck. After being stranded for 24 hours, a 2 hour charge delay doesn't seem like a big deal.
