About chargers - Traction chargers
Traction batteries are an expensive part of any electrically driven vehicle. Reliable and efficient charging equipment correctly matched to battery capacity and required recharge times are a basic necessity for operational effectiveness and optimized battery life and performance. Two charging technologies can be used to achieve this goal: WoWa chargers and HF chargers.
Conventional WoWa chargers offer a reliable and robust way to charge conventional traction batteries. They are cost-effective charging systems for traction applications where a 12- to 14-hour recharge time is appropriate. Their robustness comes at a cost, however: efficiency is only 75%.
High-frequency chargers use switch mode technology, allowing for a better power factor, increased efficiency and low DC ripple. Reduced energy consumption (15%) and extended battery life (15%) are the result.
