Sorry if my searching skills are poor. There are lots of talk about state of charge, use of supercharger and impacts on battery life, etc. I am wondering about a different scenario and its impacts: frequent short duration charging (NON supercharger). Local Whole Foods and Target provide free AC charging (for the first couple of hours). Suppose I go to Whole Foods for 20 minutes, plug in, then go to Target for another 20 minute, and plug in... and say I do this a lot... is this ok? bad? no impact?
