Plus my 30kWh battery is Lithium Iron Phosphate. Your BEV is likely a Lithium-Ion? Regardless, I should get 3,000-5,000 full charge cycles on my battery. As long as I charge it to 100% once a week I should be golden.
I have a BYD dealership 25km from my house and a 6 year/150k KM warranty. I'm pretty sure people work there, they definitely were when I visited. Given that I'm pretty sure there are people repairing PHEVs.
