Abstract

The invention relates to a city electric passenger vehicle with a super capacitor which takes the super capacitor as a power source and comprises a passenger vehicle body structure, a super capacitor group, an intelligent charger, a distributed super-capacitor monitoring system, a motor and a drive, a CAN meter, a bow pantograph of the electric passenger vehicle and a camera for monitoring the bow pantograph of the passenger vehicle, and also comprises an assistant and electrical control unit of the passenger vehicle; and the CAN meter of an SAEJ1939 protocol is adopted to realize instant messaging and information sharing in all the electrical control units by a CAN bus. The super capacitor group is taken as the power source to be linked with the motor and the drive, and respectively linked with the intelligent charger and the distributed super-capacitor monitoring system. The city electric passenger vehicle adopts the intelligent charger and automatically adjusts the charging voltage and charging current of the super capacitor group according to the environmental temperature, thus storing more electrical energy and increasing full charge endurance; and simultaneously, the distributed super-capacitor monitoring system based on an iCAN protocol is adopted to control the whole vehicle, thus having high intelligent degree and real-time response capability.

Description

technical field [0001] The invention relates to an urban electric passenger car which uses a supercapacitor as a power source and is applied in a city public transportation system. Background technique [0002] The supercapacitor electric bus or passenger car in the prior art uses the supercapacitor installed in the bus to store electric energy, drives the vehicle with electric energy, and provides electric energy to all auxiliary operating equipment of the vehicle. The basic working principle of the vehicle energy is the same as that of the trackless Trams are similar, such as figure 1 shown. The bus using the supercapacitor can be charged when it stops at the station of the bus system. When charging, the original DC rectifier network used by the trolley bus can be used as the power supply, or the AC grid power supply in the power system can be used. After step-down ( or boost) and after rectification, provide charging power for the supercapacitor electric bus. Since the...
