Looks like Avis is adopting similar rules and fees for EVs. From an email received today:
3)Battery charging levels at vehicle check out. Avis will rent the EV with at least a 70% charge on the battery. The range of your EV will vary based on a number of factors including vehicle load, driver’s actions such as speed and acceleration, climate and terrain factors such as inclines. Avis does not warrant or guarantee the range of an EV. 4) Battery chanrging levels at vehicle return. Your EV must be returned to Avis with a battery charge level of at least 70%. If returned at less than 70% but more than 10% battery charge level, a charging fee of $35 will be assessed to you. If returned with less than a 10% battery charge level, you will be assessed an additional low charge fee of $35 (a total of $70 charging fees if returned with a battery charge of less than 10%).
