description: The purpose of the work is to describe modern principles for improving the efficiency of electric vehicles, to develop a reversible device for charging and discharging an on-board energy storage device as part of a traction electric drive. The topic of the work is âTraction electric drive with on-board energy storage on supercapacitors.â Results. The main topologies for constructing static converters are considered. The principles of bidirectional energy transfer using DC/DC converters are described. A comparison was made of capacitor, supercapacitor and electrochemical storage devices. A functional diagram of a tram traction drive with an energy storage device has been developed, which allows all the recovery energy during braking to be reused. The calculation and selection of charge and discharge device components necessary for computer modeling was carried out. A computer model was developed and graphs were obtained confirming the functioning of the developed system. Application area. When developing and modernizing urban electric transport schemes in order to create economical rolling stock and reduce the load on the contact network and traction substations. Work conclusions. The considered method of energy storage in the form of an on-board supercapacitor unit will allow us to abandon the already usual energy recovery into the network, leaving the energy obtained during braking on the vehicle for later use. This approach will significantly reduce current consumption from the network and the overall energy efficiency of the vehicle. The developed part of the traction drive, the DC/DC converter - a reversible converter, will allow redistributing power flows from the traction electric drive to the storage device and vice versa.
