Embodiment Construction

[0009] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0010] A power-off indicating device includes a main body 1 and a detection part 2; it is characterized in that the detection part 2 is used for detachable connection with the detection port 7 reserved for the electric vehicle charging pile 6, and a detection circuit (not shown in the figure) is provided in the main body 1 shown), the detection circuit can generate an electromagnetic signal of a specific frequency, and a battery assembly (not shown) that supplies power to the detection circuit; For the function of emission, the outer periphery of the core body 3 is provided with a casing 4, the casing 4 plays the role of shielding electromagnetic signals, and the length of the casing 4 is longer than the length of the core body 3, so as to achieve the best shielding effect; An insulating layer (not shown) is filled between the core body 3 and the shell 4, and the ...

Abstract

The invention discloses a power-off indicating device and an electric vehicle charging pile, wherein the power-off indicating device includes a main body, a detection part and an indicator light; users and maintenance personnel can intuitively judge the status of the electric vehicle charging pile through the brightness of the indicator light status, which greatly saves time. In the event of a power failure, it can be judged whether the electric vehicle charging pile is internally disconnected or the power failure is caused by an external grid disconnection, which improves maintenance efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a power failure indicating device and a charging pile for electric vehicles. Background technique [0002] With the development of battery technology, the trend of electric vehicles becoming a mainstream transportation tool is becoming more and more obvious, and with the development of electric vehicles, the importance of electric vehicle charging piles has become increasingly prominent. However, the existing electric vehicle charging piles have the following disadvantages: Intuitively, it is impossible to quickly and directly determine whether the electric vehicle charging pile has electricity and whether it can still be charged normally, resulting in a waste of time and is not conducive to the daily maintenance of the electric vehicle charging pile . Contents of the invention [0003] In view of the above problems, the object of the present invention is...
