Liebherr's Liduro Power Port (LPO) series offers a highly efficient solution for the power supply of machines, being a market-leader in power and energy density to date. It is ideal for companies looking to improve electrification at construction sites.
The LPO 100 version can be used with maximum efficiency to supply tower cranes, fast-erecting cranes and small to medium-sized machines – for example Liebherr’s wheel loader L 507 E. The gross energy content spans from 40 kWh to 160 kWh, depending on the version, with peak outputs ranging from approx. 60 to 150 kVA. The energy storage system can supplement an insufficient grid connection or as an isolated grid. The mobile energy storage system supplies power on demand and without surplus, i.e. with an optimum price-performance ratio. Compared to diesel generators, which have a consistently high consumption of fossil energy regardless of their consumers, the LPO delivers power with a significantly higher level of efficiency and without idling phases.
The energy storage units in this series can be charged with up to 32 A and supply power to consumers via several connections that can be used simultaneously: 16, 32, 63 and 125 A. The LPO also allows concurrent charging and discharging. Energy and status monitoring is carried out via the local controller or the digital "LPO Monitoring" app for smartphones and tablets.
The LPO 600 represents the medium model range of the Liduro Power Port series. This battery-based energy storage with integrated dc fast charging stations and further ac charging connections has the gross energy content of 564 kWh, and therefore sufficient power for the supply of large machines or fleets – even with no grid connection available. The two folding dc fast charging stations (150 kW each) or additional ac charging connections allow for a quick and flexible charging of mobile machines. It is also possible to charge the LPO 600 via different connections.
The Energy Planner is a browser-based software for holistic planning of the power and energy requirements of a construction site in various construction phases. The tool helps construction site and fleet managers, electrical and energy planners or dispatchers with the energy planning, set-up and monitoring of a construction site.
