System comprising at least one electrically propellable vehicle

A system comprising:

• at least one electrically propellable road vehicle;
• and
• at least two electric conductors extending along a road section on which the road vehicle is adapted to travel,
• wherein at least one of the electric conductors is formed by at least two conductor segments arranged consecutively along a lengthwise direction of the road section, said conductor segments being electrically isolated from each other,
• wherein the at least one electrically propellable vehicle comprises at least one electric motor arranged to propel the vehicle, an electric energy storage device electrically connected with the at least one electric motor and a current collector adapted to connect electrically with said at least two electric conductors, the current collector being electrically connected to the electric energy storage device, the system further comprising:
• at least two vehicle external charging devices being connected to two or more of the electric conductors, to provide a voltage thereto adapted for charging the electric energy storage device of the at least one electrically propellable vehicle, each charging device being connected to one or more conductor segment, and
• charging device control means configured to control the at least two vehicle external charging device said charging device control means being provided with communication means,
• wherein the at least one electrically propellable vehicle comprises vehicle control means and communication means adapted to connect with the communication means of the charging device control means to transmit at least one charge signal thereto indicative of at least one charging parameter comprising a desired charging current for the electric energy storage device of the vehicle, and
• wherein the charging device control means is configured to, in response to said at least one charge signal, order one or more of the at least two vehicle external charging devices to provide a current to the thereto connected conductor segment or conductor segments corresponding to the desired charging current.
