When charging at home or at work, expensive electric vehicle batteries are parked much longer than they actually need to charge. During this time, the price of electricity and the needs of the power grid fluctuate cheerfully. The InnoCharge software package uses batteries of electric vehicles intelligently to reduce charging costs and sustainably increase the profits of B2B customers. This opens up promising business models for charge point operators, electricity suppliers, and automotive OEMs. The clearly emerging mass market of infrastructure that enables feeding energy back from the vehicle to the grid (V2G) even further increases the benefits of smart charging optimizations.
