Vehicle charging station having degraded energy storage units and methods thereof
First Claim
1. A computer-implemented method for a charging station to provide power to a vehicle energy storage unit on an incoming vehicle, the method comprising:
- predicting power of the vehicle energy storage unit when the incoming vehicle arrives at the charging station;
determining power to be supplied by at least one energy storage unit on the charging station having a degraded state and power to be supplied by a power grid connected to the charging station based on the predicted power of the vehicle energy storage unit of the incoming vehicle;
based on the power to be supplied by the at least one energy storage unit having the degraded state, pre-filling the at least one energy unit before the vehicle arrives at the charging station based on a predetermined table, wherein the predetermined table comprises information about the at least one energy storage unit and corresponding fill time; and
providing the power to the vehicle energy storage unit from the at least one energy storage unit on the charging station, the power grid and a combination thereof.

Abstract
The systems and methods disclosed herein are directed to a vehicle charging station having at least one energy storage unit in a degraded state. The station may provide power using the energy storage unit to an electric or hybrid vehicle. In an illustrative embodiment, power from the station is provided to the vehicle from the energy storage unit, power grid or a combination thereof. Logic or processes for providing power to the energy storage unit for the charging station may depend on a variety of factors including, but not limited to, capacity of the energy storage units, number of units, information about an incoming vehicle to charge, etc. After charging, the energy storage unit in its degraded state may be used for fast charging the vehicle.
