Tritium Miller Relay400x275Tritium, a global developer and manufacturer of DC fast chargers for electric vehicles, and Miller Technology, which supplies mobile mining equipment, have announced they are providing innovative fast chargers and light duty battery EVs for the mining industry. The inaugural project at the BHP Mitsubishi Alliance mine in Queensland, Australia, is a milestone that supports the BHP Group’s commitment to reach net-zero emissions by 2050.

Tritium said it provided RT175-S fast chargers to BMA for the project. At 175 kW of output, the RT175-S can provide about 106 miles (171 km) of range to an EV in as little as 10 minutes. The charger is liquid cooled with a sealed and IP65-rated enclosure that protects the power electronics against dirt and dust on mine sites.

“As the only liquid cooled, IP65-rated EV charging technology provider, Tritium is uniquely positioned to support the mining industry’s transition to electric vehicles through innovative charging technology that is sealed to protect against sediment, dust and moisture, and rated to operate in harsh conditions,” said Jane Hunter, CEO of Tritium. “Tritium’s chargers have been operating in the field since 2013 across an array of conditions from the Nordics to Australia. 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 said it made modifications to the RT175-S in order to meet and exceed Australian mining standards. Modifications influenced the design of its latest charging products, with inclusions such as additional safety standards and filtration capabilities.

Miller Technologies provided BMA their all-new, 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 runtime through regenerative braking technology. Miller said it has 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,” said Paul Summers, the lead battery electric vehicle engineer at Miller Technology. “As a result, the Relay is the most environmentally friendly, safe and efficient light duty mining vehicle of its kind available today.”

Designed entirely in-house, the Relay can carry a two-ton payload and provides 1,550 Newton-meter (Nm) of torque, Miller said. It uses an efficient and robustly tested rechargeable energy storage system (RESS), and charges through the combined charging system type 2, one of the most widely adopted and convenient charging standards, the company added.

Miller said the latest technologies continue to be explored, including engagement with fully autonomous electric vehicles for mining, as well as the development of hydrogen fuel cells as an energy source. More details on Miller Technology’s Relay can be found at its website.
