Analysis of energy consumption characteristics of dual-source trolleybus

Making use of the grid in Beijing, a dual-source trolleybus was developed, and achieved driving it by battery packs in off-grid area. Because of using a composite power system, the energy flow of the vehicle is multi-directional and multi-dimensional. To use the energy rationally, the energy flow was researched and energy consumption was tested with grid accessing The energy consumption distribution of dissipative components was obtained, influencing factors on energy consumption including vehicle body construction, speed and temperature were analyzed. This paper proposed four methods to reduce energy consumption and improving efficiency.
