The research results indicate that during peak hours at the charging station, the probability of electricity consumption exceeding the storage battery's capacity is only 3.562 %. After five years of operation, the charging station has saved 5.6610 % on electricity costs.
Trocker et al.'s research reveals that, in scenarios with low levels of electrification on bus routes, installing fixed-energy storage units can, on average, reduce total costs by 1.8 %, while in fully electrified situations, the average cost reduction is 0.4 % .
