Comment Tesla's experiments (Score 2) 46
Tesla experimented with this and discovered many people would charge up at work, then use the power at home in the evening leaving just enough charge to get back to work in the morning to recharge. A great life-hack to cut your utility bill, but the downside was the battery cycling dramatically reduced the life of the cells. If used properly, such as only during power outages or emergencies it is a very handy solution. When used daily, it will cost more for early replacement of the battery than the owner will save in utility bills.
