Power grid fluctuation prompt method and device of portable charging pile during charging

Abstract

The invention provides a power grid fluctuation prompt method and device of a portable charging pile during charging. The method comprises the following steps of acquiring a current power grid voltage in real time when a portable load device is used for charging a load device; judging whether the current power grid voltage conforms to a charging demand or not according to the size of the power grid voltage; and indicating that excessive long charging time can occur or the load device cannot be fully charged if the current power grid is used for charging the load device when the power grid voltage is lower than a low voltage state, and outputting a warning signal to remind a user. By the method, a vehicle owner can be reminded of knowing a charging environment in real time and is prevented from carrying out troubleshooting caused by mistakenly thinking that the vehicle breaks down.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a method and device for prompting grid fluctuations when a portable charging pile is charging. Background technique [0002] With the gradual enhancement of people's awareness of environmental protection, electric vehicles have become an inevitable trend in the development of the world's automobile industry. The society has gradually begun to accept and use electric vehicles. One of the most important tasks, with the gradual clarification of the national construction of electric vehicle charging stations and charging piles, the construction of charging stations for electric vehicle charging has begun to enter a substantive stage, while household charging piles and portable charging piles are also gradually marketed. Among them, portable charging piles are often used for outdoor temporary charging locations, which have a single function and cannot detect grid fluctuatio...

AI Technical Summary

Problems solved by technology

Among them, portable charging piles are often used for outdoor temporary charging locations, which have a single function and cannot detect grid fluctuations at the selected charging location. When the user uses the portable charging pile for charging, once the charging location selected by the owner is close to the factory Nearby, the factory has some large-scale equipment that consumes a lot of power, which will cause the voltage jump of the grid here to be too large, which will affect the power of the car charger, prolong the charging time, and even fail to fully charge for a long time. At this time, the user cannot Determine the specific cause of the failure, causing inconvenience to the user
