A battery capacity selection process that considers multiple interest claims. Energy consumption and battery capacity are sensitive to its operating conditions.
In the next step, the variable operating conditions and parameters related to battery capacity selection are mathematically described, and then the optimal set of solutions for battery capacity selection is determined by using a double-layer optimization method targeting procurement and operating costs.
The commercial battery technology is still evolving rapidly. Construction machinery manufacturers must keep a close eye on advances in battery technology and update their ECM battery capacity versions in time to gain a competitive advantage. Some studies [ 39, 40] have evaluated batteries' energy density and price.
