Note the estimated recharge lifetime of only 1000 cycles.
This is not anywhere near enough - in my opinion. If one was to "top up" their EV battery once a day every day - just to feel good with regards to always leaving home with their EV battery at the 100% charge level (like we do with our smartphones) - then the EV battery would only be good for a little over 3 years (3 X 365 days = 1095 days = 1095 recharge cycles).
A charge cycle life of 3000 or more cycles would be more like it ... to go along with the estimated 800km EV range.
