Utilising ABB’s innovative battery technology, Hitachi Construction Machinery trucks can be transformed from diesel to full electric battery operation. The dump trucks will operate by utilising a new onboard electrification system – drawing its energy requirements from an energy supply system with dynamic charging, allowing simultaneous charging of the on-board energy storage system while providing energy to power the truck. The system will provide extended battery longevity by reducing the load and discharge during each haul cycle, offering a cost efficient industry solution that allows continuous operation so as to maintain the high productivity and performance the industry has come to expect from Hitachi Construction Machinery products.
Both companies signed a memorandum of understanding in March 2021 to build a partnership aimed at realising net zero emissions and this joint development is the first project where the two companies will apply their complementary skills to achieve this goal. ABB will develop the on-board energy storage systems by customising an existing product and Hitachi Construction Machinery will lead the overall design and development of the dynamic charging battery dump truck utilising the technology of its existing rigid dump truck with trolley as its base, effectively allowing the accelerated development of this solution.
Hitachi Construction Machinery and ABB understand there is a growing interest in the electrification of mining operations and machinery, as environmental awareness grows within the industry and community.
Technology continues to be further developed in an effort to reduce greenhouse gas emissions, while taking into consideration the demands of mining operations.
By utilising Hitachi Construction Machinery’s dynamic charging battery dump truck systems and ABB’s battery technology, the joint collaboration will not only help tackle the challenge of solving the issues involved in dump truck electrification, but also provide a real world climate change solution.
