2011-2015 Hyundai Sonata Hybrid Battery Pack and Battery Module Replacement

2011-2015 Hybrid owners. Haven’t been able to find a step by step on battery pack removal and battery module replacement? I made one for the community. The car needs all the battery’s replaced as most of the lipo cells have puffed.
understand this isn’t a comprehensive tutorial and if you attempt this, you do so at your own risk

Great vid. Seems like module 5 in mine is also bad. Measured voltage on all the cells. It read 26.6 whereas the rest read 30.2-30.5.

How do i know what module has what cell #s? is there a diagram?

[@Stang8URMPRT]

You need a scan tool to watch the cells individually. It does not throw a specific code for a specific cell. It just tells you one is under/over voltage. You can watch in live data the cell with the most and the least voltage to figure out which cell is bad. I believe there are 9 cells in each module. You can do the math to figure out which cell is in which module. It took a while to diagnose, as I’m not a hybrid specialized tech. But it’s a personal vehicle and was worth the time invested in learning.

And yes there is a diagram. I was wrong. There are 8 cells per module. Module 1 (the module all the way to the left in the video) has 1-8. Module 2 has 9-16 and so on.

Where can I order the module my battery just die ..

[@Stang8URMPRT]

Can only get them used on eBay. There are a few sellers and I’ve purchased from a few of them.
