I think assassinated is the appropriate term here as it’s politically motivated.

Here is a paper on the relationship between heat and battery degradation

Any AC load you can throw at an EV is effectively “slow charging”. My car supports a maximum of 9.6kw from an AC charger, but up to 150kw from DC fast chargers. Even with the fast charging, its not like a phone, it has active thermal management which will cool the battery and slow down the charging if it gets too hot. phones don’t really have that and is mainly why they degrade faster if quick charged.
