A towing vehicle and the trailer include respective batteries and electric powertrain for propulsion. A connector system connects the vehicle and trailer via a plurality of conductors, a plug, and a socket including at least seven connector pins. Due to the wire gauge, each conductor carries no more than 20 amps. When a driving state is detected, a first switch matrix in the vehicle and a second switch matrix in the trailer enter a first configuration to connect a plurality of light sources in the trailer to a lighting signal generator in the vehicle. When a charging state is detected, a second configuration of the switch matrices is entered in order to carry a charging current which is divided in parallel among a plurality of conductors in the connector system and then recombined in order to provide a charging current greater than 20 amps.
