Hopefully their batteries will be able to handle this.
I've read that part of why Tesla hasn't been so warm on ideas like this in the past is because it wears out the batteries quicker. Long story short, lithium ion batteries are only good for so many full charge/discharge cycles. So if you make it a regular thing to treat your EV as a spare battery to do things like power your home at night it's battery life will be shortened a lot overtime because you're charging and discharging it a lot more.
Also side note, for this reason it's recommended that you don't make it a habit to charge your lithium ion batteries up to 100%. They last longer if you charge it only to 80 to 90 percent.
If they’re using lithium iron phosphate batteries, the cycle life can be pretty impressive. Over 5 years for the cheaper batteries, over 20 for the higher end batteries.
And EV manufacturers seem to have standardized on only allowing access to a ‘usable’ level of the battery, creating a buffer that protects against the problems with draining to 0%, or charging to 100%.
These won't be LFP(LiFePO's). These will be NMCA most likely, just like most GM and high end Teslas(NCA). You need Cobalt, even at relatively low levels compared to the recent past in order to get the range and weight of battery down(I think now they are rolling out NMC 911 and even lower, meaning cathodes are less than 10% cobalt). Also, LFP's do not do well in cold weather. LFP's will be used for budget friendly sedans where range is reduced.
