Yutong has reported successful operation of over 100 battery electric mining trucks at the Baoqing Chaoyang open-pit coal mine in Heilongjiang, China. The 100-tonne class YTK145E trucks replaced diesel haulers in extreme cold conditions, with temperatures below -20°C lasting months. The fleet achieves 96% availability, 32 trips per day in winter, and 20 trips in summer despite muddy roads and steep ramps. This is one of the largest new energy mining truck deployments in the region. The project supports China's dual carbon strategy by cutting diesel use and emissions at a major lignite mine with over 800 million tonnes of reserves. Yutong's trucks use integrated coaxial dual-drive motors, third-generation long-life batteries with 4,500 charge cycles, and four-gun fast charging. The operator chose electric after successful trials in Xinjiang and Inner Mongolia. The article provides concrete operational data and shows that large-scale electric mining fleets can work in harsh climates. For carbon markets and climate finance, this case demonstrates real decarbonization in a hard-to-abate sector. It offers a replicable model for cold-region mine electrification, with potential to scale across northeast China and similar environments. The fleet's performance metrics and preventive maintenance strategy are worth noting for anyone tracking industrial electrification progress.
