Energy storage unit Liduro

The Liebherr energy storage unit is a powerful and flexible storage unit for electric drive systems based on double layer capacitors. The compact, liquid-cooled complete system comprises all of the individual systems and assemblies needed, thereby making integration in an application significantly easier. As such, Liduro is a cost effective and sustainable system for increasing the productivity of electric drive systems and facilities.
Storage medium Double layer capacitors
Energy content 1,500 kJ

Features

Integration

Integration

Simple mechanical and electrical integration in a plant or system. Only the electrical power cables as well as the power supply and cooling need to be connected. A CANopen and Profinet interface is available for extended functionality.

Safety

Safety

A sophisticated protection concept forms the basis for safe operation of the storage unit in relation to the device and operator. An isolating unit with fuses and switching contacts disconnects the storage unit from the power supply in the event of an error.

Device protection

Device protection

The high protection class IP65 and the robust mechanical and electrical design ensure the device's protection. Continuous monitoring of the process and status information increases the intrinsic protection and extends the device's overall operating time.

Housing

Housing

The housing combines utility and design. Dust and water do not pose any problem. The connection unit of the power cables and the plug interfaces are correspondingly sealed, this allowing both indoor and outdoor operation.

Analysis

Analysis

The OPAL software provides a versatile and easy-to-operate program for parameterisation, observation and analysis. When using an industrial PC as a superordinate control, OPAL offers automatic data logging for advanced system analysis.
