Abstract

A method and device for vehicle charge resource management are disclosed. The vehicle charge resource management includes polling a plurality of docking stations for docking indication data, and identifying a docked set therefrom. State-of-charge data for each respective ones of the docked set is assessed, and a recharging rate for the each respective ones of the docked set. Recharge status data may be generated based on the recharging rate to indicate a time-to-recharge for the each respective ones of the docked set. When the recharge status data compares unfavorably with the state-of-charge data for the vehicle power supply, transmitting a user input request that includes the recharge status data to prompt user input. User input data is received, and recharge command data generated therefrom. The recharge command data may be transmitted to initiate a recharge of at least one of the docked set via the vehicle power supply.
