The companies' inaugural project at a BHP Mitsubishi Alliance coal mine in Queensland supports the BHP's commitment to reach net-zero emissions by 2050.

Tritium provided RT175-S fast chargers to BMA for the project. At 175kW of output, the RT175-S can provide 171 km of range to an EV in as little as 10 minutes.

This charger is liquid cooled with a sealed enclosure that is IP65 rated, protecting the power electronics against dirt and dust on mine sites.

Tritium CEO Jane Hunter said as the only liquid-cooled, IP65-rated EV charging technology provider, Tritium was uniquely positioned to support the mining industry's transition to electric vehicles through innovative charging technology sealed to protect it against sediment, dust and moisture, and rated to operate in harsh conditions.

"Tritium's chargers have been operating in the field since 2013 across an array of conditions from the Nordics to Australia," she said.

"In this industry, that's a long history of proven track record, which gave Miller Technology the confidence to choose Tritium to partner with them in this operational change in support of their goal to reduce emissions at their sites."

Tritium made modifications to its already robust RT175-S fast charger to meet and exceed Australian mining standards.

The modifications made during this project influenced the design of Tritium's latest charging products with inclusions such as additional safety standards and filtration capabilities.

Miller Technology provided BMA with its fully electric light duty vehicle, the Relay.

Capable of charging in as little as 20 minutes for a typical 10-hour mining shift, the Relay can add up to two hours of additional run time through regenerative braking.

Miller Technology lead battery electric vehicle engineer Paul Summers said Miller Technology had invested more than a decade of research and development into the Relay, concentrating on serviceability, modularity with rugged design and construction.

"Relay's technology creates a game-changing vehicle with its unique battery management system and cooling and temperature monitoring capabilities," he said.

"As a result, the Relay is the most environmentally friendly, safe and efficient light duty mining vehicle of its kind available today.

"We're proud to have provided BMA with the industry's most advanced solution for sustainable mining in partnership with Tritium and its market-leading fast charging technology."

The Relay can carry a 2t payload and has 1550 Newton-metre of torque on tap.

It uses a rechargeable energy storage system.

The Relay charges through the combined charging system type 2, one of the most convenient and most widely adopted charging standards.
