A system for cycling battery cells with pressure regulation is disclosed. The system comprises supports for receiving the battery cells which insert in a clamping arrangement having jaws moving one with respect to the other by an actuator operated by a controller in order to apply a pressure in a pressure application axis to the cells. A pressure sensor measures the pressure applied to the cells while a cycling module connected to the cells performs their cycling and measures their charge and discharge level. A programmable processing unit ensures a control of the pressure and, if desired, the temperature applied to the cells according to a programmed cycling mode and records data representative of the pressure and other cycling measurements.

A remote-controlled vehicle adapted to be mounted on at least one conductor and to pass over an obstacle encountered thereon. The vehicle includes: a frame, inspection systems, motors used to move the vehicle, a remote control system, at least two carrying arms pivotally mounted to the frame and exerting a pressure in the direction of the conductor(s) for suspending the frame to the conductor(s) and two opposing wheels attached to each carrying arm in order to enable the vehicle to travel along said conductor(s) while suspended. The axis of rotation of each of the wheels is inclined in relation to the vertical axis and at least one of the wheels is actuated by the motors. At least one temporary support rotor is equipped with at least two pivoting blades disposed above the corresponding conductor in order to temporarily support the vehicle when one of the wheels encounters an obstacle.

The invention concerns a remote-controlled vehicle designed to be mounted on a support and capable of clearing an obstacle on the support. The vehicle comprises first and second mobile frames. At least one articulated arm is mounted mobile on the first frame and a wheel is mounted on the articulated arm to maintain the vehicle on the support. A fastening means co-operates with the wheel and is adapted to retain the wheel on the support. At least one temporary support arm is mounted mobile on the second frame. The temporary support arm comprises retaining means for maintaining the vehicle on the support. The vehicle comprises motor means connected between the frames and the arms for moving same with respect to one another so as to clear an obstacle encountered on the support.

A vehicle for use on a live line. The vehicle is provided with three coplanar traction wheels mounted on a frame and spaced along a first longitudinal axis parallel to the live line and above therefrom. The vehicle is also provided with two movable coplanar pressure wheels mounted on the frame and spaced along a second longitudinal axis parallel to the line and below therefrom. The vehicle has a driving motor mounted on the frame, for driving the traction wheels. The motor has a source of energy, such as batteries. The vehicle has a pressure mechanism mounted on the frame and coupled to the pressure wheels, for maintaining the line squeezed between the traction wheels and the pressure wheels. The vehicle has a control mechanism coupled to the motor for controlling the motor. Thereby, in use, the vehicle is moved along the line. The vehicle can also be provided with a de-icing tool. The de-icing tool has a collar with two parts opening and closing around the line. The collar supports several blades concentrically spaced apart from each other and forming an open cone in a forward moving direction of the vehicle.
