Trailer type electric bus

Abstract

The invention discloses a separable trailer type electric bus. The separable trailer type electric bus comprises a traction carriage, a trailer carriage and hitching systems, wherein the traction carriage mainly comprises a power system, an operation control system, a hitching system and a power battery pack, the power battery pack supplies power for equipment in the traction carriage, an operation control system controls equipment in the two carriages to run; the trailer carriage mainly comprises a power battery pack and a hitching system, the power battery pack supplies power for equipment in the trailer carriage, and when the traction carriage and the trailer carriage are connected together by the hitching systems, a power battery in the trailer carriage supplies power for the power system or other equipment in the traction carriage. By the adoption of the separable trailer type electric bus, the operation of a bus company becomes more flexible, energy waste can be reduced, the service life of the power batteries can be effectively prolonged, and maintenance and replacement cost of the power batteries and bus running cost can be lowered.

Description

technical field [0001] The invention relates to an electric bus, in particular to a trailer type electric bus. Background technique [0002] In recent years, the rising price of fossil fuels has affected the development of the world economy. The high oil price has greatly increased the operating costs of buses. In addition, the greenhouse gas emissions of traditional fuel vehicles have affected the environment. Governments of various countries have begun to seek new energy sources for vehicles. technology. In the past, electric vehicles were only a concept in China, but after several years of development, some important technical issues of electric vehicles have been partially resolved, especially the power source and management issues. However, there are still some problems in the current large-scale application of electric buses, which make it difficult to popularize rapidly. [0003] Electric buses need to use a large number of power batteries and are expensive. At the ...

AI Technical Summary

Problems solved by technology

At present, under normal circumstances, the weight and volume of the power battery pack system itself are very large. If such a heavy and large battery pack system is loaded on the carriage, a lot of power will be lost in the power supply carriage itself, and the energy utilization rate is low. Moreover, under the current technology and production conditions, the price of power batteries is expensive, and few bus companies can afford the cost of power batteries as many as one carriage.

At the same time, the compartment space of the electric vehicle is not adjustable. If the electric vehicle is used as a bus, even if the passenger capacity of the compartment can meet the demand of the passenger flow during the peak period, the passenger load rate during the off-peak period will be reduced. Under low conditions, it will cause serious energy waste, and the battery life will be greatly reduced, so the frequency of battery replacement will increase, which will further increase the purchase and operation costs of the bus company
