An acquaintance stopped by my house today to charge his Roadster (v2.0, non-Sport) on my HPC. There were 64 ideal miles showing in Standard mode, and the battery temperature was at the first yellow. PEM and motor temperatures blue.
So we plugged in the Roadster, and the display said: "Preparing to charge. Battery cooling: 0% complete." But then nothing happened. The fan didn't come on, no power appeared to flow, and the indicator stayed at 0%. Fifteen minutes later, still at 0%.
We tried all sorts of things; turning the car on, resetting the charge port, connecting with the 110v mobile plug. But the car seemed insistent on cooling down without using the fan. (The fan would come on every five minutes or so, but shut off after a few seconds.) It took two hours for the "Battery cooling" to finally reach 100%, at which point the car began charging fine (and blowing the fan like gangbusters as usual).
Does this sound like a firmware glitch? I'm pretty sure the Roadster should have been blowing its fans constantly to cool the battery while preparing to charge.
