Hitachi and ABB sign electric dump truck deal

A collaboration agreement has been signed between Hitachi Construction Machinery and ABB to develop an engineless, full battery rigid frame dump truck that will feature a customised on-board energy storage system.

The full battery dump truck will use ABB’s innovative battery technology to transform Hitachi dump trucks from diesel to a fully electric battery operation.

The project will reduce greenhouse gas emissions and offer operators a solution towards a net zero emission pathway.

The full battery dump truck is the two parties’ first collaboration project after they both signed a memorandum of understanding in March 2021.

Operated by a new onboard electrification system, the dump truck will draw its energy requirements from an energy supply system through dynamic charging to allow simultaneous charging of the on-board energy storage system while providing the necessary energy to power the machine.

The on-board energy storage system will be developed by ABB while Hitachi will lead the design and development of the dump truck using an existing rigid dump truck and a trolly at its base.

ABB has limited the volume of the batteries on the vehicle to maximise the battery dump truck’s payload capacity.

The energy storage system will extend the battery’s lifespan by reducing the load and discharge during each haul cycle, offering operators a cost-efficient solution which also allows continuous operation.

Hitachi says both they and ABB understand the growing need and interest for the electrification of mining operations and machinery as demand for environmental sustainability continues to grow.

The collaboration, they say, will not only help offer a solution in dump truck electrification but also provide a real-world solution for climate change.

Hitachi Construction Machinery spokesperson, Sonosuke Ishii, says both parties are excited for what the collaboration may bring.

“The strengths and knowledge of both companies will be utilised to realise the early development of dynamic charging battery dump trucks,” Ishii says.

“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, the basic technologies required for net-zero emissions from mining machinery can also be established as part of the current development.

“Both companies will continue with development while looking ahead for the future.”
