Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 The trolley bus power system shown includes: a drive motor, which is connected to the final reducer; an integrated controller that integrates components such as a motor controller and an inverter, and the AC side drive control of the integrated controller is connected to the drive The DC side of the motor and the integrated controller are connected to the DC bus; the DC bus is connected to a supercapacitor system, a power battery system and an isolated DC / DC converter; the input end of the isolated DC / DC converter is connected to a collector, and the output The terminal is connected to the DC bus; the input terminal of the isolated DC / DC converter is connected to the power battery system through the first switch.

[0021] Further, a diode for preventing the braking energy from feeding back to the power battery system may also be conne...

Abstract

The invention relates to a novel two-source trolleybus and a power system thereof. The novel two-source trolleybus power system comprises a power battery system, a super-capacitor system and an isolation-type DC / DC (direct-current / direct-current) converter, so that the running, safety and production problems can be fundamentally solved. A current collector is used for powering the entire power system through the isolation-type DC / DC converter, the trolleybus is electrically isolated from a wire network through the isolation-type DC / DC converter, and the step voltage can be avoided. By utilizing a composite vehicle-mounted energy, the vehicle-mounted energy can be rapidly charged, the requirement of instantaneous high power of the motor can be met, and the running distance of the two-source trolleybus is increased. The voltage on the output end of the isolation-type DC / DC converter is adjusted through a controller, so that a reasonable storage space of the vehicle-mounted energy system is guaranteed so as to store the feedback brake energy.

Description

technical field [0001] The invention relates to a novel dual-source trolleybus and its power system. Background technique [0002] As a traditional technology, trolleybus once played a certain role in the field of urban public transportation, but due to its own defects, along with the development of technology, trolleybus was gradually replaced by fuel-powered public transportation vehicles. [0003] As environmental pollution and energy problems continue to intensify, trolleybuses have returned to people's vision: trolleybuses can meet the needs of air pollution control, meet the development direction and technology development needs of new energy vehicles, and the market also shows certain demand. [0004] Traditional trolleybuses must remain on-line and cannot run off-line, and have poor safety, are prone to step voltage, high energy consumption, and do not have the function of braking energy recovery. Moreover, at the production level, it cannot be produced on the same ...
