PROTECTION ARRANGEMENT FOR AN ELECTRIC VEHICLE
First Claim
1. A protection arrangement (1) for a current collector (3, 10) arranged on a vehicle (20) having an electric propulsion unit (22) and a rechargeable energy storage (23), where the protection arrangement (1) comprises a first protective state (4) in which the current collector (3, 10) is covered by the protection arrangement (1) and a second open state (5) in which the protection arrangement (1) allows contact between the current collector (3, 10) and a corresponding current supply means (6) during charging of the energy storage, characterized in that the protection arrangement (1) is automatically opened from the protective state (4) to the open state (5) when the vehicle has reached a predefined charging position.

Abstract
A protection arrangement for a current collector arranged on a vehicle having a rechargeable energy storage includes a first protective state in which the current collector is covered by the protection arrangement and a second open state in which the protection arrangement allows contact between the current collector and a corresponding current supply during charging of the energy storage and where the protection arrangement is automatically opened from the protective state to the open state when the vehicle has reached a predefined charging position. The current collector can be enclosed when the vehicle is not charged and the protection arrangement can open automatically when a charging position is reached. This can improve the safety of the vehicle and obviate the need of a specific circuit breaker that can disconnect the current collector from the electric energy storage. The charging of the vehicle can also be simplified.
