Embodiment Construction

[0051] The embodiment of the present application provides a dust detection method, a detection device and a charging pile. By collecting the operating temperature of the charging module and the output power value of the charging module, it is judged whether it is necessary to perform dust removal treatment on the dust-proof net in the charging module. Through the technical solution provided by the embodiment of the present application, the blockage of the dust-proof net can be automatically identified, reducing the workload of manual inspection of the dust-proof net, reducing unnecessary replacement of the dust-proof net, and reducing maintenance costs. And it can automatically detect dust accumulation, which can remind the dust filter to be replaced in due course, so as to avoid a sharp drop in charging efficiency caused by poor heat dissipation.

[0052] Embodiments of the present application are described below in conjunction with the accompanying drawings. Those of ordinar...

Abstract

The embodiment of the invention provides a dust accumulation detection method and device and a charging pile. The method is applied to a charging device, a charging module is arranged in the chargingdevice, and a dustproof net is arranged on the outer side of the charging module. The method comprises steps that a first temperature signal is collected, and the first temperature signal is the temperature of the charging module; a first output power value is collected, and the first output power value is the output power value of the charging module; and a first alarm signal is generated according to the first temperature signal and the first output power value, and the first alarm signal is used for indicating that the dust screen needs dust removal. The method is advantaged in that blockage of the dust screen can be automatically recognized, a workload of manual inspection of the dust screen is reduced, meanwhile, unnecessary replacement of the dust screen is reduced, and maintenance cost is reduced; and accumulated dust is automatically detected, replacement of the dustproof net can be reminded in time, and great reduction of charging efficiency caused by poor heat dissipation isavoided.

Description

technical field [0001] The present application relates to the field of charging, in particular to a dust accumulation detection method, a detection device and a charging pile. Background technique [0002] Charging pile is a kind of electrical equipment for charging electric vehicles. With the development of electric vehicles, the demand for charging piles is also increasing. With the popularization of electric vehicles, the requirements for the charging speed of charging piles are getting higher and higher. At present, charging piles mostly use high-power DC charging mode. As the power of the charging module in the charging pile increases, the heat dissipation of the charging module becomes higher and higher. In order to ensure the normal operation of the charging pile, the charging pile (mainly the charging module in the charging pile) is cooled by air cooling at present. [0003] A fan is installed inside the charging pile. Through the work of the fan, the external cold...
