Remote diagnostic instrument for pure electric vehicle (PEV)

Abstract

The invention discloses a remote diagnostic instrument for a pure electric vehicle (PEV). The remote diagnostic instrument comprises a bus interface module, a processing module, a positioning module, a mobile communication module, a voice interface module and a power module, wherein the bus interface module is connected with a vehicle-mounted bus and is used for acquiring bus information; the processing module is connected with the bus interface module and is used for receiving and processing the bus information transmitted by the bus interface module; the positioning module is connected with the processing module and is used for determining position of the PEV; the mobile communication module is connected with the processing module and is used for carrying out communication between the processing module and a remote service platform; the voice interface module is connected with the processing module and can be externally connected with an audio input-output device; and the power module is used for providing a power source to the modules. By adopting the remote diagnostic instrument, technical faults of the PEV can be remotely diagnosed and immediately maintained, and meanwhile electric quantity of a battery can be monitored and the nearest charging station can be quickly found so as to timely charge the battery in case of power shortage of the battery.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a remote diagnostic instrument for pure electric vehicles. Background technique [0002] At present, due to the pollution of fuel vehicles to the environment and the continuous rise of international oil prices, pure electric vehicles, as a branch of green new energy technology, have the advantages of zero emission, low noise, relatively simple structure, and diversification of transportation energy sources. It has gradually attracted people's attention, and its market share has also increased year by year. [0003] However, pure electric vehicles still have many unsatisfactory shortcomings. At present, there are few charging stations for pure electric vehicles, insufficient urban coverage, and inconvenient search. The existing diagnostic instrument cannot find the nearest charging station, which cannot meet the convenience and speed of pure electric vehicles. Charging requirem...

Problems solved by technology

[0003] However, pure electric vehicles still have many unsatisfactory shortcomings. At present, there are few charging stations for pure electric vehicles, insufficient urban coverage, and inconvenient search. The existing diagnostic instrument cannot find the nearest charging station, which cannot meet the convenience and speed of pure electric vehicles. Charging needs, and the existing diagnostic instrument can only analyze vehicle faults on site, and cannot diagnose remotely. If a fault occurs, it cannot be analyzed and repaired in time, which increases maintenance costs
