Customer ServiceIn the domain of battery technology, the Depth of Discharge (DoD) is one of important factor in determining a battery''s overall lifespan. Specifically, a battery subjected to regular deep discharges, for instance, to 80% of its capacity (equating to an 80% DoD), is likely to experience a reduced lifespan in comparison to a battery typically discharged to merely 50%
Customer ServiceThereafter, benchmarking of internal and external batteries is performed by using the functions as guidelines, resulting in a variety of design solutions. The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest.
