Problems solved by technology

[0003] In the prior art, the general bus energy storage system uses supercapacitors. Due to the low energy density of supercapacitors, the stored energy is less, so it cannot run purely electric for a long time, especially when the traffic jam is serious, it is necessary to frequently start the engine to supply energy Charging, the energy of the supercapacitor all comes from the engine, while driving at low speed, the efficiency of the energy link is low, resulting in poor fuel economy

Abstract

The invention discloses a power device of a plug-in series-parallel hybrid electric bus. The power device comprises a generator, an engine, an automatic clutch, a driving motor, a motor controller and a whole control box, wherein the whole control box is provided with a lithium battery energy storage system, an electric inflating pump and an electric power-assisted steering pump; the lithium battery energy storage system is provided with an outer charging interface; and the whole control box is respectively connected with the generator and the motor controller. By the way, the power device of the plug-in series-parallel hybrid electric bus can realize purely electric running, effectively reduce the discharge of tail gas and improve the economical efficiency of fuel oil.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a power device for a plug-in hybrid electric vehicle. Background technique [0002] With the development of domestic new energy vehicles, various hybrid vehicles have emerged one after another, and their structural forms are mainly divided into series, parallel and hybrid. Among them, the prospect of hybrid vehicles in the domestic bus market is promising, and the existing hybrid buses in various cities are also mainly hybrid vehicles. [0003] In the prior art, the general bus energy storage system uses supercapacitors. Due to the low energy density of supercapacitors, the stored energy is less, so it cannot run purely electric for a long time, especially when the traffic jam is serious, it is necessary to frequently start the engine to supply energy Charging, the energy of the supercapacitor comes from the engine, while driving at low speed, the efficiency of the energy link...
