It's not been a very pleasant week. Of the new tires I put on the Sedona two weeks ago (by hand), one has had a three inch blowout in the tread. The backpack that holds my laptop popped it's zipper on the way out the door yesterday. It took TWO hours to drive 50 miles into work in stop and roll traffic. And then... this: Dat Error Code by Ophbalance posted Jan 18, 2017 at 6:12 PM This is not a code you ever want to see show up. Ever. 'E's not pinin'! 'E's passed on! This hybrid 0is no more! He has ceased to be! 'E's expired and gone to meet 'is maker! 'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't nailed 'im to the perch 'e'd be pushing up the daisies! 'Is metabolic processes are now 'istory! 'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-HYBRID!! Which is to plainly say that the traction battery is no more. Specifically it's indicating that cell #5 has kicked the proverbial bucket. My car, as a 2005, is 12 years old and has 172,000 miles on it. I can't see the point of spending whatever it is mother Toyota wants to sell a new pack for. PriusChat seems to indicate that $4k is pretty average as they'll want to sell you the ECU as well. A re-manufactured pack goes for about $1700. A salvage pack, if you can actually find one, might be $500. But even then who knows the state it would be in and how low the cells have fallen as it sat unused. So the point of this thread then; I'm going to document rebuilding the hybrid battery pack and replacing the bad cells as needed. It's not going to be pleasant. It's going to be brutally boring at times. It's going to take near to a month to complete. But it should cost me less than $500. And 1/3 of that cost can be recouped. So here's how it works. You have to pull the pack out of the car first. You then test each of the 28 cells in order to see which is out of spec, marking which ones are bad. You order replacement cells. And that's where the fun starts! You pick up as many LiPo/NiMH chargers as you can afford (a charger that can do 4 cells costs about $200). It takes 3 cycles of charging/discharging to bring each cell into balance. There's 28 cells to do this to. The entire cycle takes about 1.5 days to complete. With two chargers it should take about a week to bring all the cells into balance, with the final step being that you tie all the positive and negative posts together amongts all the cells to balance them within pack. Sounds easy, but it's going to be time consuming. So first steps is to order the chargers and wait for them to come in. I can take the pack out of the car but there's really not much to be done with the cells until the kit comes in. So as the repair progresses I'll make updates to the thread. In the meantime I'm going to pray that there's not too much rain (or any snow) as I'll be riding the black bitch into work for the next month.
