Health monitoring system of airport electric vehicle power system

Abstract

The invention belongs to the technical field of airport operation guarantee and provides a health monitoring system for an airport electric vehicle power system. The system comprises a vehicle-mounted data acquisition terminal, a micro weather station, a data transmission network and a cloud data platform, wherein the vehicle-mounted data acquisition terminal is connected with an airport electric vehicle power system and is used for acquiring the power battery pack information of the airport electric vehicle power system; the micro meteorological station is arranged in the operation environment of the airport electric vehicle and collects meteorological elements of the operation environment. The cloud data platform is respectively connected with the vehicle-mounted data acquisition terminal and the micro meteorological station through a data transmission network, a trained health assessment model is stored in the cloud data platform, and the model obtains the health condition of the power battery pack according to the information of the power battery pack and the meteorological elements. Health prediction of the power battery pack in different operation environments is realized, the health monitoring level of the power battery pack can be improved, and the method has an important value for preventing the thermal runaway hidden danger caused by the reduction of the health level of the power battery pack.

Description

technical field [0001] The invention belongs to the technical field of airport operation assurance, and specifically, the invention provides a health monitoring system for an airport electric vehicle power system. Background technique [0002] The airport electric vehicle is an important guarantee equipment for airport operation, and the health status of its lithium battery power system (or airport electric vehicle power system) is directly related to the safe operation level of the airport. [0003] The electric vehicle power system health monitoring system in the prior art is mainly aimed at ordinary social vehicles, and airport electric vehicles are very different from ordinary social vehicles in terms of operating environment and vehicle structural characteristics, for example: airport electric vehicles operate on the apron, The apron has the characteristics of unshielded, large-area hardened pavement, and the ground temperature is much higher than that of ordinary socia...

Problems solved by technology

[0003] The electric vehicle power system health monitoring system in the prior art is mainly aimed at ordinary social vehicles, and airport electric vehicles are very different from ordinary social vehicles in terms of operating environment and vehicle structural characteristics, for example: airport electric vehicles operate on the apron, The apron has the characteristics of unshielded, large-area hardened pavement, and the ground temperature is much higher than that of ordinary social roads under high temperature and strong sunlight; at the same time, the battery packs of the battery power system of some airport electric vehicles are installed The temperature of the battery pack has a great influence

Since the aforementioned factors are not fully considered in the actual operation of the vehicle, if the current electric vehicle power system health monitoring system is applied to the health monitoring of electric vehicles in airports, the health status will be inaccurate and affect the normal use of electric vehicles in airports.
