I work for a company that drives vehicles 24/7 on corporate property where the maximum speed you can get to is around 30mph, and that's pushing it. I am set to research for a vehicle with better mpg....from what I understand a vehicle such as the Ford Escape Hybrid would utilize the battery power the whole time in that speed range and only regenerate during braking or when the gas engine kicks in. Wouldn't I have a problem of depleting the battery completely and not being able to properly recharge it?

Can someone please help me with this?
