Liebherr to showcase its smallest energy storage system, holistic power planning software at bauma

The call for the electrification of construction sites is becoming a popular way to meet climate targets for emission reductions. Businesses must address their dynamically growing energy demands in response to the existing and upcoming emissions regulations.

Access to power supply on construction sites is often limited or non-existent. Consequently, electrified construction sites face challenges like machine operation at maximum power, charging numerous machines during breaks, and smoothing load peaks. 

The Liduro Power Port (LPO) is an energy storage system from Liebherr that supplies power on construction sites. It allows for local emission-free operations and charges hybrid or fully electric construction machinery and equipment. The high-power density and compact design of LPOs supplies machines and construction sites with diverse power requirements.

Mobility and flexibility with Liebherr's LPO 100

Liebherr will present the smallest model of the Liduro Power Port, the LPO 100, at this year's bauma. It can be used with maximum efficiency to supply tower cranes, fast-erecting cranes, and small- to medium-sized machines, like Liebherr's L 507 E wheel loader. The gross energy content ranges from 40 kWh to 160 kWh, depending on the version, with peak outputs from roughly 60 to 150 kVA.

The energy storage system can supplement an insufficient grid connection or be used as an isolated grid when no connection is available. The mobile energy storage system supplies power on demand and without surplus. Compared to diesel generators, which have a consistently high consumption of fossil-based energy, the LPO delivers power with a higher level of efficiency without idling phases.

The energy storage units in this series can be charged up to 32 A and supply power through several connections that can be used simultaneously: 16 A / 32 A / 63 A / 125 A. The LPO also allows concurrent charging and discharging. Energy and status monitoring is carried out via the controller or the digital LPO Monitoring app for smartphones and tablets.

The series is available as the LPO Basic without a chassis or as the LPO Drive with a trailer chassis. Moreover, the LPO can be moved on-site with suspension points, using a crane or excavator, and lifted and moved from all sides, using a forklift truck.

LPO 600: energy for large machines and fleets

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 a gross energy content of 564 kWh and can supply power for large machines or fleets — even when no grid connection is available. 

The two folding DC fast charging stations (150 kW each) or additional AC charging connections (type 2, 32 / 65 / 125 A, power lock) allow for quick and flexible charging of mobile machines. It is also possible to charge the LPO 600 through different connections, like 32 / 63 / 125 A, CCS2 or power lock.

The Energy Planner software

Energy Planner is a software for holistic planning of power and energy requirements of a construction site in various phases. The tool helps construction site and fleet managers, electrical and energy planners, or dispatchers to plan energy needs, implement the set-up, and monitor the progress on a construction site.
