SELECTIVA 2KW AND 3KW: COMPACT SPECIALIST SOLUTIONS FOR SMALLER TRACTION BATTERIES

Product

12/11/2017

Fronius has launched two intelligent and cost-effective solutions for smaller traction batteries onto the market in the form of the new Selectiva 2kW and 3kW battery charging systems. The new models are the “little brothers” of the now well-established battery charging systems in the 8kW and 16kW power categories, as well as the successors to the Selectiva Plus E range. Like the larger models, they use the Ri charging process developed by Fronius. This process automatically detects the various parameters of the connected battery, such as its age, temperature and state of charge, and adapts the charging characteristic accordingly. As a result, overcharging – which causes high energy losses and harmful warming of the battery – can be reduced to a minimum.

Selectiva 2kw und 3kw

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.
