I carried jumper cables in every car I've owned since my first--a 1930 Model A Ford--until now. Sure, I still carry a portable "jump and carry" battery/compressor/USB power source to use for others (in ICE vehicles) and to recharge my Model X's 12VDC battery in case it runs down. But why hasn't the industry created an apparatus that would let one EV charge another? When we're stuck on a freeway for 22 hours in freezing weather, our batteries can run down too. When we misjudge the available charge remaining (or the car does), we can be stranded in the middle of the freeway with no power to get to safety or to a third-party recharge point a few miles away. But what if we had a "Jumper Siphon" cable that would let us connect to any EV willing to share a bit of their charge? We could call a friend to come help and twenty minutes later, we're back on the road.
Yes, I expect that would take a bit of thinking as the battery systems in our Teslas are probably not designed to let power flow OUT of the charge port. But that's just technology and foresight. Any entrepreneurs out there who need funding to make this happen? Does such an apparatus exist?
