Fronius Battery Charging Systems ideal for AGM- and EFB-Technology

Automobile manufacturers are currently focused on developing fuel-efficient technology. Alongside the discussion regarding various alternative energy solutions, optimization of modern vehicles is also becoming increasingly important. One such example is the use of start-stop technology. This technology, which uses Absorbent Glass Mat (AGM) batteries and Enhanced Flooded Batteries (EFB), is designed to reduce urban fuel consumption by up to 20%. These premium, high performance modern batteries require equally advanced charging systems that ensure a long battery service life, such as the powerful Acctiva Professional 35A and the Acctiva Professional Flash battery charging systems from Fronius.

As conventional lead batteries cannot cope with the frequent vehicle restarts that are a feature of start-stop technology, only AGM batteries or the slightly cheaper EFB variants can be used. Both systems work reliably under these particular conditions and ensure cycle stability. A special fibre mat absorbs the electrolyte in AGM batteries and the active material in EFB batteries. While EFB solutions were developed for simple start-stop functions, the AGM battery also supports energy-saving functions in the vehicle.

To ensure optimum capability of the AGM batteries, only voltage-regulated charging devices (14.4 V) with the IU charging characteristic should be used. Overcharging, i.e. voltages over 14.4 V result in a shorter service life and may invalidate the warranty.

All battery charging systems in the Fronius Acctiva range can be used to charge Absorbent Glass Mat (AGM) batteries and Enhanced Flooded Batteries (EFB). If required, the voltage on the Acctiva Professional 35A and the Acctiva Professional Flash can be set on the display to match the manufacturer's specifications.
