A slidable current collector has an array of terminals with carbon brushes for contacting conductor rails to deliver electrical power to a moving work machine. The terminals have upper sections with a conductive post, lower sections that include a reservoir of liquid metal, and bladders that connect the upper sections with the lower sections. Magnets surround outer shells of the terminals. Fluid above a threshold pressure fed into the bladders holds the upper sections apart from the lower sections and forces the magnets away from the conductor rails. Fluid below the threshold pressure allows the magnets to clamp the terminals to the conductor, lowers the conductive post into the liquid metal, and urges the carbon brushes against the conductor rails. The bladders provide a fluid suspension distributed across the array of terminals, enabling consistent electrical contact and wear for the carbon brushes.

The present disclosure relates to techniques for scheduling electric vehicle (EV) charging sessions using an EV charger scheduling service. A method includes presenting a user interface on a client computing device, which prompts an end-user to select a time slot for using an EV charger. Upon receiving the selected time slot, the scheduling service reserves the EV charger for the end-user. The service then receives a signal indicating that an EV is connected to the charger during the reserved time. In response, the user interface is updated with a control element that, when activated by the end-user, instructs the scheduling service to command the EV charger to initiate power delivery. The method enhances the efficiency of EV charging station utilization and provides end-users with a convenient and controlled charging experience.
