About chargers - Hybrid chargers
Chopper chargers use ferroresonant transformers combined with switching technology at the secondary end. This allows for very high charging rates: a traction battery can be charged in as little as one hour – albeit reducing battery life cycle by 30%.
This solution enables multi-shift operations without spare batteries and battery changing. In terms of safety time and total cost of ownership, the combination of an expensive chopper charger plus one battery pack versus one HF charger and two battery packs is an alternative that should be seriously considered.
