A collaboration between Hina Battery and Shaanxi Tonly Heavy Industries has produced electric mining trucks utilizing sodium-ion battery technology, marking what appears to be a first in the industry. The partnership represents an expansion of sodium-ion battery applications beyond conventional electric vehicles into the heavy equipment sector.
The debut vehicle has been delivered to Sanyou Mining and is built on Tonly’s 120E series platform, integrated with Hina Battery’s proprietary Haixing series battery system. Each truck contains 676 kWh of energy storage capacity, equivalent to the battery capacity of approximately ten standard electric vehicles. The sodium-ion battery systems feature cell energy density exceeding 165 Wh/kg and can achieve full charge in 20 to 25 minutes while maintaining a cycle life surpassing 8,000 cycles even under fast-charging conditions.
The electrification of mining trucks addresses environmental and economic considerations within the industry. Conventional mining trucks rely heavily on diesel fuel consumption and generate significant emissions. Electric alternatives potentially reduce operational costs while lowering environmental impact. Hina Battery has emphasized that its sodium-ion solution leverages the technology’s extended cycle life, broad operating temperature range, and rapid charging capabilities, which align with mining industry requirements for cost efficiency, quick turnaround times, and high asset utilization.
The introduction of these vehicles reflects broader industry trends toward electrification across sectors beyond light passenger vehicles, with sodium-ion battery technology emerging as a viable alternative for applications requiring substantial energy storage capacity.
