Hey guys as this is the technical section of the forum I have a good question for one of you. I'm actually a product developer in Hong Kong that specialises in ion battery packs and I've just been asked very indirectly by a wing of Tesla to investigate the idea of creating an emergency battery for Model-S. Rather than waste weeks for all the people to relay my spec requests I presume there is one of you guys here that knows detailed info on their minimum specs? I'll be designing a concept to propose to the big guys later in the month, but I need specs and it's just taking too long to get the info! I need to know if the Model S could potentially accept power from an external battery, if so, what spec should the output be from the battery pack to be accepted to the Model-S? That's my major concern as I specialise in items that output DC5V I know this car needs something wildly different. I've been told I can have access to the Model-S connector spec later if they like the concept so the connector is not my issue it's creating something that's output power can be accepted. Anyway one of you guys may know this info so any ideas anyone?!
