City electric car power supply fast supply system based on super capacitor

Abstract

The invention discloses a supercapacitor-based urban electric vehicle rapid power supply system comprising a voltage monitoring module, a charging parking space, a charging c-frame, a charging slot, an AC / DC converter, a rectangular groove, a sliding chute, a fixed frame, a spring, a relay, an IC power meter and a control system; the rectangular groove is arranged at the position which is opposite to the charging parking space at the bottom part of a supercapacitor of an electric vehicle, the charging c-frame is arranged on the fixed frame in the rectangular groove, the spring is arranged at the lower part of the fixed frame and respectively fixedly connected with the charging c-frame and the fixed frame, the other end of the charging c-frame is connected with the upper end of the other transverse side surface in the rectangular groove in a colliding way, the sliding chute is arranged on the transverse side surface, the rectangular charging slot with positive and negative electrodes is arranged at the back part of the charging c-frame; the AC / DC converter is connected with the relay in series, the relay is respectively connected with the IC power meter and the control system, and the control system is also connected with the IC power meter. The system can charge rapidly with low cost.

Description

technical field [0001] The invention relates to a fast power supply system, in particular to a fast power supply system in the technical field of urban electric vehicles, and belongs to the technical field of power supplies. Background technique [0002] Supercapacitors (Ultracapacitors), also known as Electrochemical Capacitors (EC), are a new type of electrical energy storage device, but because of the low energy density of supercapacitors, pure electric vehicles that use supercapacitors as power sources The main problem is that the driving range after each charge is relatively short. For example, the Shanghai No. 11 electric bus, which was put into operation in 2006, uses supercapacitors as the power source. Although the charging time only takes tens of seconds, and the electric energy storage and conversion efficiency is also very high, the driving range is only 3 to 8 kilometers, so Charging devices must be set up at stops along the way to charge electric vehicles betw...

AI Technical Summary

Problems solved by technology

Because the voltage of a supercapacitor is proportional to its capacity, there is still a large gap in the charging of supercapacitor electric vehicles, especially the convenient fast charging capability. At present, there are no reports at home and abroad. It should be said that this is a constraint for electric vehicles loaded with supercapacitors. key issues of universal
