It is also possible to use a primer, that is to say a high-power energy storage system capable of providing the power required to start machines such as hydraulic pumps. A primer can restore the electrical energy faster than a conventional battery. If the device is used to operate a hydraulic pump, it is for example possible to start the pump with the energy provided by the primer; once the start is complete, the control electronics automatically switches the battery that takes over after the priming, in order to supply power to the pump during normal operation.
