AI Technical Summary
Technical Problem
Existing charging stations for electric and hybrid vehicles take longer to charge the energy storage when the vehicle is stationary, due to inefficiencies in heat management and contact dynamics.
Method used
A charging station equipped with a heat sink integrated into the charging contact, which can be actively or passively cooled, and features a deformable contact body with flexible wrapping to reduce power density and prevent overheating.
Benefits of technology
The heat sink effectively dissipates heat generated during high-current charging, reducing loading times and preventing overheating damage, while the deformable contact body ensures efficient energy transfer.

Abstract
The invention relates to a charging station (4) for charging an electric energy storage device (2) of a vehicle (1), in particular a road or rail vehicle which has a current collector (5) with at least one raisable and lowerable contact strip (10) in order to supply energy from a single- or double-pole overhead line system. The charging station (4) comprises at least one charging contact (11) per contact pole (9), said charging contact being arranged above a charging position for the vehicle (1) such that at least one point of contact (14) can be produced between the contact strip (10) and the charging contact (11) for each contact pole (9). Charging processes can be carried out with higher charging currents, and therefore with shorter charging times, in that the charging contact (11) of the charging station (4) according to the invention has a heat sink (15) for cooling the point of contact (14).
