So BEV batteries will still more than likely outlast PHEVs if the two are using the same cells and if the BEV battery is charged no more than 55% (similar voltage to PHEV to minimize calendar aging)?Li-ion batteries have almost unlimited cycles when they are limited to a narrower SOC range. That's why most PHEVs have ~30% of buffer and each cell is rated at 3.6-3.7 V instead of 4.1-4.2 V. In a HEV the battery can go through thousands of cycles in a year but they can last over a decade.
You didn't really provide an answer but it seems keeping SoC between 20 and 55% is probably going to allow the battery to last decades lol.
Yeah, the 12 CT200h I bought from my friend is still on the original HV battery though lots of driving is on the highway. Dreading the day I have to get a new OEM pack.
