First Claim
1. A charging station for an electric vehicle, the electric vehicle including a charging blade configured to receive power from the charging station, comprising:
- a charge head configured to engage with the charging blade and transfer electric power to the vehicle, the charge head including;
a housing having a longitudinal axis;
a central cavity extending along the longitudinal axis of the housing, the central cavity being configured to receive the charging blade of the vehicle therein; and
a plurality of electrode holders positioned in the housing, each electrode holder of the plurality of electrode holders including;
an electrode that extends into the central cavity through an opening on a side wall of the housing that forms a boundary wall of the central cavity, the electrode being configured to transform from an extended configuration when the charging blade is not in the central cavity to a retracted configuration when the charging blade is positioned in the central cavity, wherein (a) in the extended configuration, the electrode extends into the central cavity from within the housing through the opening on the side wall of the housing, and (b) in the retracted configuration, at least a portion of the electrode in the central cavity retracts into the housing through the opening on the side wall; and
a plurality of springs configured to bias the electrode in the extended configuration.

Abstract
A charging station for an electric vehicle may include a charge head configured to engage with the charging blade of the vehicle to transfer power. The charge head may include a housing with a central cavity extending along its longitudinal axis and a plurality of electrode holders. Each electrode holder may include an electrode configured to transform from an extended configuration when the charging blade is not positioned in the central cavity to a retracted configuration when the charging blade is positioned in the central cavity. In its extended configuration, the electrode may extend into the central cavity from a side wall of the housing, and in the retracted configuration, at least a portion of the electrode may retract into the housing. Each electrode may also include a plurality of springs configured to bias the electrode in the extended configuration.
