PROTECTION ARRANGEMENT FOR AN ELECTRIC VEHICLE

摘要

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.
