ABB will supply its battery technology, which enables trucks to transform from diesel to full electric operation, to the project. But the electric vehicle will also draw power from an overhead catenary while simultaneously charging the on-board energy storage system.

Using an energy storage systems will reduce the vehicle's curb weight and lower capex and lifecycle costs, while in-motion charging in tandem with regenerative braking on downhill runs will eliminate recharging stops.

"We are honoured to collaborate with Hitachi Construction Machinery combining extensive industry expertise and innovative technologies to improve efficiency and accelerate the transition to all-electric mine operations", said Edgar Keller, President of ABB's Motion Traction Division. "By co-creating solutions, we can help mine operators achieve their production and sustainability goals." 

"The strengths and knowledge of both companies will be utilized to realize the early development of battery electric rigid dump trucks", said Sonosuke Ishii, Senior Vice President and Executive Officer at Hitachi Construction Machinery. "In addition, ABB's energy storage solutions can also be used for static charging dump trucks and the technology is ready for future fuel cell electric vehicles. Both companies will continue with the development while looking ahead to the future." 

This joint development is a first collaboration following the memorandum of understanding signed by Hitachi Construction Machinery and ABB in March 2021 to accelerate the energy transition towards a carbon-neutral future in mining.
