Express EnCore modular fast chargers allow batteries designed for fast charging to be safely charged anytime during the shift-day. The chargers offer intelligent charging with high efficiency and flexibility, while packaged in a compact size. The modular construction adapts to a wide range of battery capacities, allowing the potential reduction of chargers in a fleet. The modules are automatically switched off and on based on charge cycle requirements to achieve optimum charging performance and always maintain peak efficiency. Should a module develop a minor fault, the charger bypasses the module for continued operation without interruption. EnCore chargers utilize the EnerSys Express Fast IONIC charge profile to continually diagnose battery condition throughout the charging process for the most effective and efficient charge possible.
