My wife and I own a small ice cream shop that has outdoor parking for eight vehicles. We'd like to offer EV charging at one of those parking lots. We would appreciate any advice or views on what kind of station to charge. One issue apart from the cost of installation, is compatibility, and time to charge. Our customers generally stay a half an hour max, but most are about 15 mins. Is it even worth it to offer charging in such a short time environment? Any thoughts on which charger to install?
