Selectiva 2 kw and 3 kw: compact specialist solutions for smaller traction batteries

The battery charging systems are designed for use with traction batteries with operating voltages of 12, 24 or 48 volts. With their compact external dimensions and a weight of around five and nine kilograms respectively, the chargers are easy to install, and offer flexible mounting options including wall-mounting. The design, operation and service plan are in line with that of the 8 and 16kW models. The devices are equipped with a large display that facilitates simple operation and the specification of a range of parameters, with faults, warnings and notes clearly displayed in multiple languages.

The user can back up and analyse relevant data and perform updates via a serial USB interface. The clever housing and airflow design protect the device from the ingress of dirt while providing effective cooling of the power electronics. The devices have a CAN interface as standard, and as such are suitable for charging lithium-ion batteries. Fronius additionally offers a whole host of options, including an LED strip for improved visualisation of the status indicators, a system for automatically topping up the water in batteries, temperature-controlled charging and an external start/stop function.

The intelligent Ri technology enables the new Selectiva devices to achieve a total efficiency of around 84 percent. In comparison with other charging processes, users can save up to 30 percent on their energy costs for battery charging. At the same time, the cooler and therefore gentle charging process extends the service life of the batteries. Both of these factors help operators to significantly reduce the costs associated with their forklift truck fleets.
