  • SELECTIVA: Battery charging systems for traction batteries

  • Maximum efficiency.
    Fronius Selectiva charging systems are highly intelligent, because charging systems for drive batteries need a special type of intelligence. Since every battery is different. The Selectiva series automatically recognises age, charge level, and other important battery criteria, to provide the precise, correct charge, in order to increase the service life and efficiency of the battery and reduce the amount of maintenance. This is a question of intelligent technology.
    Recommended fields of use:
    Ideal for medium and large ground conveyors, electric forklift trucks
    Applications:
    Charging: The Selectiva Plus charges batteries fully automatically, gently, and as rapidly as possible, until they reach their maximum capacity. Various characteristics allow charging to be optimised to suit the requirements of the application.
