Abstract: A system for charging a multiplicity of commuter EVs without dependence on the power grid is provided, using the EV batteries themselves as distributed off grid storage for all EVs connected to the system. The EV charging system comprises low cost solar modules and an intelligent charge management system capable of a providing flexible charge rate to EVs based on user demand, that is decoupled from the grid and thus does not add to peak power demands. Only a low capacity grid connection is provided for backup, and buffer solar panels may be provided for load balancing. Excessive solar energy is fed into the grid during times of low demand at the charging stations, such as on weekends.
