About electric vehicle. If you add the maintenance cost for battery, how does it fair compare to gasoline vehicle? On cost we have to pay.

I heard someone said that, at the end EV will cost you almost the same as gasoline vehicle, if you have to change the expensive battery every so often. Can someone please give me more info on this? Thank you so much.

"Maintenance" for your battery isn't something that costs you every month. Nobody is going to open the thing and fiddle with it and turn screws etc.
It all consists of 1. how you are using it and 2. how good is your battery controller, hardware and software.
I have seen an old guy on TV who was driving his Tesla daily as a salesman, and he reported about several hundred thousand miles on his first battery and then twice as much on his second. He said he does never ever charge it above 80% and never discharge below 20%.
It's worth noting that while NMC batteries shouldn't be charged over 100% for daily use, LFP batteries should be charged to 100% at least weekly.
LFP batteries are not damaged by being at 100%, and due to the flat discharge curve, the controller only knows how charged the battery is when it's near 100%. Most of the time it's calculating the charge left based on how much energy is being used.
Over time, that guess is going to get less accurate. Charging it to full will reset the guess, and keep it accurate.
Only charging to 80% can cause the guess to be off by more than 50% (after quite a long time), leading to the battery running out when the car thinks it has at least 50% left.If you don't know what battery your car has (and don't have access to the manual), assuming LFP is safest. Any EV sold after 2022 is likely to use LFP (unless it's a high performance car), and EV's sold before 2020 are probably NMC.
New battery chemistries are coming on the market every year, so don't rely too much on this comment.
