I will concede that data is limited, but I did look into Polestar 2 battery replacement cost locally: $50k AUD. Battery warranty was 7 years I think?
Even if we half that cost, it's still a significant cost that will significantly impact the resale value of a 3-5 year old EV with battery approximately mid-life and say 85-90% capacity.
And that's the big, big cost on EVs that is difficult to quantify, but holds significant risk: resale value. Doesn't help that costs are coming down on EV options in general, so you're being hit with several high likelihood depreciation factors at once. Sure, eventually gas/hybrid will see depreciation too when EV takes over, but I don't see that happening any time soon in Australia due to charging resources.
Personally I think that until we have some sort of reasonably standard/available replacement battery packs for EVs they will be a significant risk to hold onto for more than 2-3 years. This current scenario of highly proprietary batteries for each car that are difficult to replace is BS. China are already working on it, that video I posted from Shanghai auto show demonstrated a hot swap battery setup - like 3-5 minutes automated battery swap. The model would be that you simply lease/rent the battery from a battery company and swap as required, much like you'd fill a tank.
Toyota hybrid (non PHEV) batteries are cheap. Like $3-5k AUD to replace depending on model.
Oh I’ll also add:
According to consumer reports, despite theory the reliability tiers are as follows
Hybrid (best)
gas
Ev
In theory it’s the reverse but the reality is that most hybrids are Toyota and most ev are Tesla so there’s a skew.
