Vehicle-mounted electric vehicle rechargeable emergency rescue vehicle based on shaft power-take-off generator as well as working method of rechargeable vehicle

Abstract

A vehicle-mounted electric vehicle rechargeable emergency rescue vehicle based on a shaft power-take-off generator comprises the shaft power-take-off generator, a vehicle-mounted alternating-and-direct-current quick-and-slow-charging integrated device, a vehicle-mounted storage battery, a power switching module and a to-be-charged electric vehicle, wherein the power switching module is equipped with a shaft power-take-off generator access port and an external mains supply access port; the vehicle-mounted alternating-and-direct-current quick-and-slow-charging integrated device comprises a rectification module, a two-way voltage regulation module and an inversion module. When the rechargeable emergency rescue vehicle is in an idle state, the vehicle-mounted storage battery accesses a mains supply to be charged until the vehicle-mounted storage battery is fully charged; when the rechargeable emergency rescue vehicle is in a charged state and is a sedan, only the vehicle-mounted storage battery is adopted for charging; when the rescue vehicle is a medium bus or a large bus, the vehicle-mounted storage battery and the shaft power-take-off generator are adopted for combined charging. With the adoption of the rechargeable emergency rescue vehicle, the problems that existing rechargeable diesel vehicles are excessively large in size and high in noise and cannot charge storage batteries during running are effectively solved, and energy recovery at different rotating speeds output by the vehicle is realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle emergency rescue, in particular to a vehicle-mounted electric vehicle emergency rescue charging vehicle based on a shaft power generator and a working method thereof. Background technique [0002] At present, there are few electric vehicle emergency rescue charging vehicles in China. At present, most of the existing charging vehicles use diesel generators, which are bulky, noisy and cannot generate electricity normally when the vehicle is running. At the same time, the existing emergency rescue equipment lacks versatility, occupies a large area, lacks convenience and flexibility, and cannot realize the integrated function of AC and DC fast and slow charging. Therefore, it is necessary to conduct research on anti-vibration, low noise, and energy saving of emergency rescue equipment to improve the service capabilities of the emergency rescue system. Contents of the invention [0003] Th...
