Jump start my brain (please)

Sometimes I get stuck in an ICE rut even when I live in an EV world.   Picture the RAVolt stranded in a parking lot because my auxiliary battery died.  Luckily, I’ve packed jumper cables so I can start the EV with the cables.  Thinking with my ICE hat on, I ask the guy next to me for a jump.  He’s pretty amused to provide a jump to an EV and happily opens up his hood.  I connect up the cables and the RAVolt “starts” like a champ; however, it dies when I disconnect the cables because the auxiliary is too dead to run my vacuum pump.   Oh No!  I’m stranded - better call Laura and get a ride home.

Finally, I realize that I can give myself the friggin’ jump from any of my traction batteries!  20 seconds later I’m ready to drive again.  Before I go, I ask the guy who game me the jump why he didn’t say anything.  He just shrugged and said “yeah, it seemed strange, but I figured you knew what you were doing.”

After thinking on it a while, I realize that I’ve gotten so used to seeing the traction (main) battery pack as a single unit that it’s hard to treat it like a chain of 12 batteries.  Even when I describe it as 5 in the front and 7 in the back, I’d been thinking of it as one part.  What an unexpected lesson in the dangers of pattern thinking!
