Sandvik has developed a new battery that significantly improves the runtime of battery electric vehicles (BEVs) by 36 percent. The higher-capacity battery, designed for BEV loaders and trucks, offers increased energy while maintaining the same size and form factor. The battery employs a lithium iron phosphate (LFP) chemistry, which is less volatile and suitable for underground mining applications. This advancement marks a substantial improvement in safety, reliability, and performance.
The new Sandvik battery not only extends the runtime but also reduces the cost per amp-hour compared to the current-generation Artisan® battery packs. Additionally, the increased capacity enhances charge acceptance, enabling faster downhill speeds and improved efficiency. This development is the result of 13 years of technological evolution for Artisan® battery packs.
The battery is purpose-built for underground mining, featuring a modular and rugged design. It incorporates several design enhancements for enhanced strength and durability, including a revamped housing with increased rigidity to withstand shocks and vibrations. Laser-welded terminals offer a stronger connection, reducing energy loss and heat while improving efficiency and safety. The battery also includes improved cooling plates to enhance performance and extend cell life. Moreover, it boasts better protection against dust and moisture.
The next-generation LFP battery cells are encapsulated in a non-conductive potting material, reducing the risk of overheating and short circuits. Sandvik has also upgraded its battery management system to enhance reliability and functionality, monitoring each cell’s temperature and voltage to ensure safe operation.
The battery is expected to be commercially available in the fourth quarter of 2023 and will be standard equipment on all new Sandvik BEV loader and truck orders.
It can also be retrofitted on existing Sandvik Z40, Sandvik Z50, Sandvik LH518B, and Sandvik TH550B units.
