I have owned an EV for 4 years, no battery maintenance issues, but the real achilles heel is winter. EVs completely fail at winter, when the temps start dropping below freezing you are looking at 40% advertised range depending on the conditions. Strong winds and steep terrain will take that figure down further. The chargers can't push enough amps into the batteries below freezing so the charge rate is slower. You can't leave the car outside in the cold or it will need to heat it up to prevent permanent damage.
