Disclosed herein is a system for wireless power transmission (WPT) inductive charging batteries of an electric vehicle (EV) while parked in an automated parking garage, the system including primary coils and secondary coils. The primary coils are permanently attached to structural elements that define each of the parking spaces in the garage to which electricity is transferred from the grid. In non-pallet garages secondary coils are temporarily attached to the exterior of each EV that has to be charged by the system. In pallet garages the secondary coil is permanently attached to each pallet in the system during the initial installation of the system in the garage. In embodiments of the system the same supporting electronics are used for several primary coils. Embodiments of the system are configured to allow bi-directional, i.e. grid to vehicle (G2V) and vehicle to grid (V2G), transfer of power.

This invention discloses an energy management method for charging stations in transportation hub parking lots based on hierarchical reinforcement learning, relating to the fields of smart grid and electric vehicle charging control technology. The method includes constructing a hierarchical control model architecture and dividing vehicles into multiple groups based on urgency. Upper-layer agents output recommended power for each group based on the overall load status of the parking lot and the characteristics of each group, using a flexible actor-critic algorithm. Lower-layer electric vehicle agents use the upper-layer recommended power as part of their state, combining their own state and real-time electricity price to output the charging and discharging power of specific vehicles. A multi-objective reward function incorporating electricity cost, range anxiety, and battery loss is constructed for network training. This invention solves the curse of dimensionality problem under large-scale electric vehicle access, balancing user cost, charging satisfaction, and battery health. It also considers the vehicle-to-grid model, improving voltage fluctuations by allowing electric vehicles to discharge during peak grid demand.
