A supercapacitor and accelerating contact line hybrid tram system is proposed. A tram consumes high energy during acceleration but, low energy thereafter. Supercapacitors can be charged fast but, they have low energy density. During acceleration, a tram draws power from accelerating contact line.
Hybridization is a combination of different storage technologies with various characteristics to downsize the overall system and direct the unfavorable load conditions such as severe charge or discharge current fluctuations to a more sturdy ESS (i.e., SC). 39-41
Supercapacitors with advantages of high-power density, fast charging speed and long cycle life, have very promising application prospects in many fields such as transportation and energy storage. Usually, the onboard operation profiles will be recorded and sent to remote monitoring terminal for further study. As the working condition of onboard supercapacitor …
To realize economical operation of a catenary-free tramline, we propose installing a stationary energy storage system (SESS) to assist the electric grid for trams charging.
