Presentation Summary

• With the market introduction of dynamic energy storage systems OPTESYS® with specific adaptive regulation and control, field experiences were gathered over more than 10 million km with commercially available hybrid buses and trucks.
• Specific configuration and functionality aspects will be described based on large EC capacitor systems providing 3MJ of energy at 750 V for heavy duty operation.
• Influences of cell-to-cell balancing between the individual energy cells were recorded during the different operating modes. The obtained experiences have been leading towards optimal energy management and enhancements towards durability, serviceability and lifetime
