Problems solved by technology

[0002] At present, new energy electric vehicles are developing rapidly. In order to meet the needs of electric vehicle charging, the state strongly supports the construction of DC charging piles in various places. After each charging pile is completed, it is currently tested by electric vehicles. However, if there is a problem with the new charging pile, it will be charged. Electric vehicles cause serious damage. Under this background, there is an urgent need for a DC charging pile detection equipment with small size, comprehensive detection functions and portability.

Abstract

The invention relates to a portable DC charging pile detection device. The device comprises an interface socket, a load circuit, a CAN bus communication circuit, a power supply module, a connection identification circuit, an MCU, a liquid crystal display module and a keyboard, wherein the liquid crystal display module and the keyboard are connected with the MCU. The interface socket is connected with a charging gun of a charging pile; each part of a device circuit connected with the interface socket identifies reliable connection of an interface through pull-up and pull-down resistors; load resistors are switched through a relay to change load current; the MCU is communicated with a DC charging pile through a CAN bus to control charging, and meanwhile, the MCU is a master control portion of the device and controls each resistor of the device to work normally; and a liquid crystal displayer displays the detection result. The device controls current and voltage output by the charging pile and detects values of the current and voltage output by the charging pile, thereby realizing detection of the charging pile; and the device has the advantages of being small in size and portable.

Description

technical field [0001] The invention belongs to the technical field of electrical detection, in particular to a portable detection device for a DC charging pile. Background technique [0002] At present, new energy electric vehicles are developing rapidly. In order to meet the needs of electric vehicle charging, the state strongly supports the construction of DC charging piles in various places.
