Systems and methods are provided herein for administering services (e.g., charging rates, charging costs, user experiences, etc.) to an electric vehicle based on a characteristic of the electric vehicle. This may be accomplished by an electric vehicle charging station (EVCS) charging an electric vehicle and using one or more sensors to capture information about the electric vehicle. The EVCS can using the captured information to determine a characteristic of the electric vehicle. The EVCS can then use the determined characteristic of the electric vehicle to administer a service. For example, an EVCS may capture an image of an electric vehicle and use image recognition to determine the model (i.e., vehicle characteristic) of the electric vehicle. The EVCS can then charge the electric vehicle using a first charging rate (i.e., service) based on the model of the electric vehicle.

To sufficiently exert charging and discharging performance of a cell while reliably protecting the cell, a battery controller determines ΔVlimit which is a limit value for a difference between a CCV and an OCV of a cell module, which is a secondary cell, and determines at least one of an upper limit voltage and a lower limit voltage of the cell module. An allowable current of the cell module is calculated based on the ΔVlimit and at least one of the upper limit voltage and the lower limit voltage determined in this manner.

A fuel cell recovery control system and method are provided to supply hydrogen to the cathode of a fuel cell stack to remove an oxide film formed on a platinum surface of the cathode. The performance of the fuel cell stack is recovered in accordance with the oxide film removal. In addition, electric power generated during the performance recovery of the fuel cell stack is consumed in an inverter and, as such, overcharge of a battery is prevented.
