An emergency braking extension device includes an emergency braking extension loop, a first emergency braking extension train line and a second emergency braking extension train line. The emergency braking extension loop has a protective circuit breaker, a normally open contact of an emergency braking button, and an emergency braking extension relay, which are sequentially connected in series. A normally open contact of the emergency braking extension relay is connected in series to a pantograph lowering control loop. A first normally closed contact and a second normally closed contact of the emergency braking extension relay are connected in series to a return line and a power supply negative loop of a train emergency braking control loop, respectively. A third normally closed contact of the emergency braking extension relay is connected in series to a control loop of a bypass cut-off circuit of a train emergency braking execution loop.

An installation for recharging an energy storage means, such as a battery of an electric vehicle, by conduction of energy from an electric power source to the energy storage means, where the battery is electrically connected to an on-board device and provided with a plurality of electric contacts, and on the ground, a ground device, combined with the on-board device, is connected to the electric power source and includes a plurality of electric contacts, each electric contact of the ground device being able to be put into contact with a corresponding contact of the on-board device, and the installation being able to safely apply an electric recharging power issued by the electric power source to the battery, where the plurality of electric contacts of the on-board device and of the ground device exclusively includes a phase contact and neutral contact.

An electrically driven vehicle contains a current collector for supplying electrical energy from a bipolar overhead line system. The collector has an articulated support rod, which bears, on the contact wire side, a contact collector having a contact strip, and which is coupled, on the vehicle side, to a lift drive for positioning the support rod and for pressing the contact collector to a contact wire of the overhead wire system, a detection device for detecting a lateral position of a contact point of the contact wire on the contact strip and a driver assistance system for executing an automatic steering intervention as a function of the detected lateral position of the contact point. The vehicle has increased availability for a feed of electrical energy from the overhead line system in that the contact strip is supported on the contact collector via at least two spring elements.

A computer system includes processing circuitry configured to simulate, using electrical multi-battery models, the performance of a propulsion electrical energy storage system of a vehicle based on logged vehicle routes of the vehicle, the electrical energy storage system comprising multiple electrical energy storage packs, predict a lifetime of the electrical energy storage system based on the simulated performance of the propulsion electrical energy storage system and extrapolating forward assuming a worst-case aging rate; if the predicted lifetime exceeds a predetermined lifetime, indicate that an electrical energy storage pack downgrade replacement is required, and reduce a state of charge window of the electrical energy storage system at a rate such that a predetermined minimum state of charge window is not reached before a planned electrical energy storage pack downgrade replacement.

A non-rail bound, electrically or hybrid-electrically driven vehicle has a current collector for feeding electric traction energy from an overhead line system. The current collector has a sliding strip that is brought into sliding contact with a contact wire of the overhead line system above a travel lane. The sliding strip arrangement is pivotable transversely to a direction of travel. The vehicle has a limiter to at least unilaterally limit the transverse pivoting range of the sliding strip arrangement substantially to the width of the vehicle. A driver assistance system assists a driver in adhering to a virtual track within the marked lane. The track width and the pivoting range are dimensioned such that, when the track is adhered to, it is possible to maintain sliding contact between the sliding strip arrangement and the contact wire.
