Choosing the right technology
Basically, both lead-acid and lithium traction batteries provide power for electric drives. But that’s where the similarities end: they each have specific technical and commercial advantages that come into play depending on their intended use. Only on the basis of a sound analysis of the application profile can a reliable statement be made about the optimum energy package. These include, for example, operating procedures, shift models, intermediate charging options, grid connection capacities and local conditions. There is no one-size-fits-all answer as to which technology is better.
Total Cost of Ownership
The economic viability of different battery technologies cannot be assessed on the basis of acquisition costs alone. A lifetime consideration such as Total Cost of Ownership (TCO), on the other hand, is a suitable basis for the investment decision. Depending on the application scenario, a lithium-ion battery can pay for itself in just a few years compared to a lead-acid battery. This is mainly due to the higher number of cycles and the associated longer service life, lower maintenance costs, lower operating costs and better vehicle availability.
Technological advantages of lithium
– Higher energy density: same performance with a smaller installation space
– Emission-free: no separate loading space with ventilation required and no explosion hazard due to oxyhydrogen gas
– Constant power: Reliably high power even when no longer fully charged
– Ease of use: No water filling and battery change necessary
– Energy efficiency: Higher efficiency of the technology
– Decentralized charging management: fast and intermediate charging for maximum vehicle availability
– Lifetime: Multiple number of cycles
