Northvolt, a European supplier of battery cells and systems, has signed an agreement with Pon Equipment to supply battery systems for Pon's Z-line series of battery electric excavators.
Northvolt will provide Pon with its Voltpack Core lithium-ion battery systems. They are designed to replace diesel engines and can be used as a standalone unit or in conjunction with other components and systems to provide OEMs with a full battery-electric power system.
Features of the Voltpack Cork include:
- installed capacity of ~94 kWh
- voltage of 576–797V
- measures 553 h x 834 l x 930 h mm (21.8 x 32.8 x 36.6 in.)
- weighs 613 kg (1351.4 lbs.).
Pon, the Cat dealer for Norway and the Netherlands, will use the battery systems in combination with electric powertrains for full electrification of its Z-line excavators. The batteries will be integrated into 12- and 25-tonne variants of the Z-line excavator, featuring 150 and 300 kWh of installed battery systems respectively.
Initially, Northvolt will supply 90 systems to Pon which plans on delivering its new electric excavators to select customers starting in spring 2021.
Emad Zand, President Systems, Northvolt, comments, “With this partnership, Northvolt is keenly entering into a new market with its battery systems. The electrification of construction equipment will usher in important change for the industry. The solutions we are demonstrating here will come to contribute greatly to a reduction in urban pollution and our dependence on fossil fuels.”
Erik Sollerud, Managing Director of Pon Equipment, comments, “We are now at our third generation of our battery electric excavators and are increasing our volume significantly. Having a solution-oriented supplier like Northvolt, located close to us and most importantly having a very clear sustainability profile in their manufacturing of batteries, from raw materials to end product, is supporting our strategy. It is exciting to work with the creative and innovative people in Northvolt.”
Charging of the Z-line excavators is enabled through a standardized CCS2 quick charging interface, or during the night on a standard utility grid CEE connection.
Operators can expect a runtime between charging when engaged in heavy excavation of between 5 and 6 hours, and between 6 and 8 hours when involved in light operations such as landscaping and light excavation work. The machines can also be run continuously when connected to the grid.
Pon's Z-line 310 and Z-line 320 will meet increasing demand for zero emissions construction equipment. Northvolt notes in its press release the need for electric powered equipment continues to grow as governments increasingly focus on reducing carbon dioxide (CO2) emissions. Cities and governments are also looking to reduce noise levels, especially in city centers; electric powered equipment operates quietly, enabling their use in cities where noise is a factor.
