Abstract
BACKGROUND: The study is based on the need to improve the performance of traction batteries for urban electric rolling stock.
AIM: This work aimed to determine the service life of the battery based on the route length of urban electric transport networks in autonomous mode without a contact network.
METHODS: Computer simulation of the operation of autonomous electric rolling stock was used based on the dynamics of movement, battery parameters, and its charge level for various operating modes.
RESULTS: A combined diagram has been developed to show the relationships between the length of battery-assisted driving sections, the number of cycles, and the service life of the traction battery. A formula is proposed to determine the battery life based on the route length and operation rate.
CONCLUSION: The findings may be used by transport companies and energy system developers to optimize the selection and operation of traction batteries.
