Hitachi and ABB collaborate for the electrification of a dumper

The collaboration between Hitachi Construction Machinery and the Traction division of ABB was born to create a fully electric dumper at the service of heavy-duty mining operations. Currently, this partnership has reached a crucial phase through the accomplishment of the prototype, already been subjected to the first tests in the factory. It was shipped on January 20th, 2024 to the copper and gold mine at Kansanshi, in Zambia, where the demo and final test phase will be executed at half 2024 at the latest.

The prototype development project started in 2021, with the target of satisfying the growing demand for electric dumpers in the mining sector and sharing in the reduction of greenhouse emissions. Using the innovative battery technology by ABB and DC/DC converters with high energy efficiency, Hitachi Construction Machinery dumpers have been transformed from diesel to fully electric. These dump trucks use a new onboard electric system that draws energy via a pantograph to power the motor directly and to charge a battery energy storage system. Moreover, while driving downhill, the regenerative braking system charges the battery itself, so decreasing the charge power when the truck is connected to the pantograph, allowing the truck to remain in constant operation without charge interruptions, maintaining high productivity, while a sophisticated system of energy and thermal management of the battery maximizes its duration.

Fabiana Cavalcante, Mobile e-Power Manager, ABB Traction, stated:  «We are pleased to ascertain that our collaboration with Hitachi Construction Machinery has reached this crucial time. The project not only aids in facing the problems linked with the electrification of these trucks but it also shares in enabling a world with low carbon emissions through the reduction of greenhouse emissions. We cannot wait for the prototype to demonstrate its real capabilities in the copper and gold mine in Zambia».

Development of a sovereign uncrewed aerial system

Rotor Lab, an electric motor manufacturing company, has announced its intention to support companies selected for the Advanced Strategic Capabilities Accelerator (ASCA) first innovation challenge.
The challenge, which was announced last year, calls for the development of a sovereign uncrewed aerial system (UAS) and trusted autonomy industrial capability. 11 companies have since been selected by ASCA to submit prototypes by April 2024, alongside a production plan showing how they will meet production requirements over 3 years.
CEO of Rotor Lab, Andrew Simpson, says Rotor Lab will be offering their newest innovation – a small but ultra-powerful and efficient electric motor – to companies taking part in the challenge.
«Rotor Lab’s new electric motor, RL22, has been specifically designed to address the unique requirements set forth by ACSA innovation challenge – both in technical and sovereign production considerations. The motor itself encompasses smart integrated features and a sleek design, built using Rotor Lab’s proprietary design and production process. This allows us to rapidly produce cost-effective motors at the lowest lead times with a particular focus on safety and powertrain integration».
Andrew Simpson continues  «Rotor Lab is based locally in Canberra and all design and production takes place in Australia. We have spent 18 months building out a secure sovereign supply chain for this critical component of a UAS, which is essential for any company wishing to claim sovereign capability for the production of the whole system». He finishes by saying that  «RL22 is just one product in Rotor Lab’s latest innovative product line which is being developed solely for sub-25kg UAS».

Test benches, integration of sensors into the measuring system

Schabmüller, which manufactures electric motors for mobile machines, has developed with HBK a new concept of a test bench for a new drive type. It combines the advantages of a precise and accurate testing and measuring system in cycles with the pluses of a comfortable development of the test bench. This concept allows easy integration of sensors into the measuring system and checking tests according to the collected data. Due to the formula database, which provides also formulas for the DSP calculation in real-time, the motor developer can create individual calculations quickly and easily – for customizable measuring and test activities.

Schabmüller uses a combination of Genesis HighSpeed data acquisition system by HBK with Perception software, which processes large data volumes quickly and reliably. Using a freely programmable interface, Perception exchanges the measured data with LabView software, which controls the single components of the test bench and automated test processes.

The electrification plan for tourist buses is coming to London

Tootbus tourist bus operator will collaborate with the provider of solutions for electronic fleets VEV, starting from the supply of 100% renewable energy and 10 Tootbus battery chargers for electric buses. VEV will entrust Tootbus with powering its current electric fleet composed of three vehicles and will also install solar energy plants by Tootbus Wandsworth deposit to generate 65,000 kWh. Tootbus will exploit the VEV-IQ platform of smart energy management. VEV’s proprietary system allows fleet operators to monitor the power supply, charge infrastructures, and use vehicles to keep their fleets in motion and maximise energy efficiency.
Gavin Brooking, managing director of Tootbus UK, stated: «The green tourism is at the core of our corporate strategy and represents a huge investment for us. We have acknowledged the massive potential that the shift to a sustainable end-to-end electric fleet might have in helping us hit our targets of emission reduction. With its broad expertise in the sector of smart energy management, VEV is for us the ideal partner with a tailored turn-key solution».
VEV has shared the details of its new partnership with Tootbus, underlining they expect their green energy solutions will help the touristic bus company save 15,567 kg of carbon emissions yearly.

Completed the tests for cold climatic conditions

Everrati Automotive Limited, specializing in the integration of powertrains for electric vehicles (EV), has completed the winter tests of its first Land Rover Series ordered in the United States. In the last months, this first IIA Series has undergone a severe validation programme of all components, focusing on the performances and the reliability of the electric powertrain group at the OEM level. Tests have been carried out at high altitudes and under cold climatic conditions and the Everrati team has guaranteed the high-voltage reliability and tested the charge function.

Stellantis invests in sodium-ion batteries

The venture capital fund of Stellantis, Stellantis Ventures, has announced they will take part as a strategic investor in Tiamat, a French spin-off of the Centre National de la Recherche Scientifique (CNRS), which develops and markets the technology of sodium-ion batteries. It is a technology that offers a lower cost per kilowatt/hour and it is lithium-and cobalt-free, granting higher sustainability. The sodium ion technology promises more convenient energy storage than the current technology of lithium-ion batteries.

“Finding new options to rely on more sustainable and economically accessible batteries that use raw materials with broad availability is one of the key ambitions of our Dare Forward 2030 strategic plan, according to which we will zero our net carbon emissions by 2038,” declared Ned Curic, Chief Engineering and Technology Officer from Stellantis.

In addition to the sodium-ion battery with Tiamat, Stellantis is investing in other alternative technologies for energy storage, such as the solid-state batteries with Factorial Energy and the lithium-sulfur chemistry with Lyten Inc.

Tiamat will use the proceeds of the fund-raising plan, of which also Stellantis Ventures is part, to implement a plant of sodium-ion batteries in France. In the early phases, batteries will be intended for electrical appliances and stationary storage applications, whereas in the future the production will be increased with specific second-generation products for BEV vehicles.
