50 Hz transformer technology continues to be widely used in battery charging systems for traction batteries. However, this gives rise to high energy consumption as well as warming the battery excessively during charging, which reduces its service life. Modern high frequency technology is also available and, although more efficient in this respect, there are major differences here too.
With the Ri charging process, Fronius is offering the best technology for charging lead-acid traction batteries available on the global market. Unlike other processes, this process does not follow a fixed characteristic, but adapts to the requirements of each individual battery. This ensures maximum energy efficiency and a long battery life. The Ri charging process went into production in 2013, with the new generation of our Selectiva battery charging systems. Numerous well-known companies from different sectors have been using it successfully ever since.
