Built-in charger intelligence for automatic power control

Dynamic Power Limitation

Dynamic Power Limitation (DPL) is an automatic function included as standard in Micropower ST. By controlling a defined group of chargers, DPL ensures that total charging power never exceeds the available mains capacity, effectively eliminating high power peaks and reducing energy related costs. DPL provides full power when capacity is available and shared power when needed – automatically and without any operator input. This helps avoid unexpected electricity bills while enabling reliable fast and opportunity charging across the fleet.

Built-in charger intelligence for optimized battery rotation

Best Battery Choice

Best Battery Choice is a built-in functionality in Micropower ST that supports optimal battery rotation and charging room efficiency. By utilizing communication between ST chargers, operators are guided toward the most suitable battery available for charging in any given situation. This helps ensure optimal usage of the entire battery fleet, prevents premature battery wear and extends overall battery lifetime. With BBC, Micropower ST enables more balanced battery utilization and higher operational availability – without adding complexity for operators.
