As a new green transportation tool, electric engineering mining truck has gradually emerged in the fields of mining and heavy transportation. As the core power source of electric truck, the performance of high-voltage lithium battery directly affects the endurance, load capacity and overall operation efficiency of the vehicle. This paper will deeply analyze the high-voltage lithium batteries with different voltage levels such as 384V, 540V, 614V, 768v and 800V to help enterprises and engineers better understand the application of these batteries in engineering mining trucks.

I. Basic concepts of high-voltage lithium batteries

high-voltage lithium battery is a kind of battery with lithium as its main component, which has the advantages of high energy density, long cycle life and low self-discharge rate. In engineering mining trucks, high-voltage lithium battery has become an ideal choice because its demand for batteries is mainly focused on high power output and high energy density. Batteries with different voltage levels have different characteristics and application scenarios, and are suitable for different types of mining trucks.
