• Selectiva Plus 8kw

The new three-phase Selectiva battery charging systems for 24V, 36V, 48V and 80V batteries feature a brand new charging process. The successful Active Inverter Technology with the revolutionary Ri-charging process adapts itself to the requirements of the battery and only charges the battery with the current that it actually needs. Conventional battery charging technologies work on the basis of a predefined, fixed charging characteristic and totally ignore the state of the battery.

New Ri Charging Process

Adapting the current to the battery prevents charging losses when charging commences and during the recharging phase. The battery only receives the current that it actually needs.

The new Ri-charging process therefore guarantees the coolest and gentlest charge, extending the battery service life to its maximum.

Applications

  • The state of the battery is determined by its effective inner resistance
  • The charging characteristic is adapted according to the age, temperature and state of charge of the battery
  • The appropriate level of current is fed to the battery during each phase of the charging process
  • Every single charging cycle is hence unique and has its own characteristic

Maximum Energy Efficiency

When charging a traction battery, the flow of energy from the socket via the charger to the battery is represented in the form of total efficiency.

  1. This is followed by an electrochemical process in which the battery is charged by means of a charging characteristic.
  2. This is referred to as charging efficiency
  3. Multiplying both processes together gives the total efficiency
