Fleet operator risks for using fleets for V2G regulation

► V2G regulation cycle life of EREV batteries must be >50,000 cycles to be profitable. ► Present knowledge and test data about the impact of V2G cycles on battery life are limited. ► Replacement of batteries and energy throughput are major factors in the cost-benefit analysis. ► V2G fleet is not viable with present data but can be viable with some technical advancement.
