Prii Battery Discharge Issues

If the 12V battery has enough charge to close the relays to the High Voltage battery, you should be able to drive immediately. It's the HV battery that powers the car (and charges the 12V battery and starts the ICE). The 12V battery is mostly there to boot the computers and close the HV relays, though it also supplies voltage to the lights and radio. I am not being precise here. It is extremely unlikely, and certainly not after just two weeks, that the HV battery would be so discharged that you couldn't drive until the ICE charged it.

Legend/OE if you ask me...

 

Yup, sounds like a mixup of facts. Car's 12V battery kept going dead and THAT happened for several weeks, "until it fixed itself" (owner learned to close hatch) is more likely.

 

If the HV battery were that low, I don't think it would be able to start the ICE. The whole thing smells fishy to me.

"Whatever possessed you to do it that way?" I've asked that question dozens of times over the years, but what I was really thinking was "What the f**k were you thinking...or were you even thinking at all?" People do a lot of dumb things. I think all machinery needs a cockpit voice recorder, so we can sift back through the wreckage and find out what really happened, as opposed to what people say happened. My wife and I need one for normal conversations too: "No, you SAID you would...."

In non-hybrid cars, there is an increasing application of data logging/recording due to the increasing complexity of the technology that is installed in the car (it also helps the manufacturer prove operator abuse, which gets them out of having to pay for warranty repairs that are due to abuse). I am still learning about what is in place on the Prius, but for non-hybrid cars, big brother is certainly watching you.
