Interaction between Charging Management and Battery Ageing

The battery system is the "heart" of every electric bus: It not only defines the bus's technical properties, but also significantly influences the costs. A battery system is by far the most expensive component in an electric bus, accounting for up to a third of the acquisition costs. In addition, the lifespan of current solutions is still limited, meaning that transport operators have to plan at least one battery replacement for the service life of an electric bus.

It is therefore crucial for transport operators to always establish optimal conditions both during the trip and during charging, and to operate battery systems as sparingly as possible. The charging management system (CMS) is responsible for planning and controlling charging processes, and can positively influence the technology's lifespan by taking the battery specifics into account correctly.
