Comparing Battery Costs Between Charging Infrastructure Alternatives

Övrigt konferensbidrag, 2025

Different electrification infrastructure concepts for electric vehicles can be difficult to compare economically because they use batteries in different ways. Often, there are options with frequent high-power short-time charging or slower charging with deeper charging cycles. This paper presents a method for comparing the battery-related costs associated with these options and applies it to long-haul trucks using different types of charging infrastructure. The battery related costs can then be compared to the cost differences between different infrastructure options to identify the best overall solution. Many existing battery aging models do not fit this type of investigation well, either requiring too much information and computation time, or do not cover e.g. the approximate dynamic behavior of the battery. To address this, we introduce a novel model designed to approximate how different use cases influence
battery-related costs for a generic battery type, rather than modeling the behavior of any specific battery pack.
