Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging, and in particular to an intelligent charging monitoring system and equipment. Background Art

[0002] New energy vehicles are becoming increasingly popular in China, and charging is one of the main issues facing new energy vehicles. The most common way to charge new energy vehicles is through public and dedicated charging piles; another way is home charging, which involves installing dedicated charging piles in the family's garage or underground parking lot to charge new energy vehicles.

[0003] When charging at home, new energy vehicles often have a safe charging current threshold, also known as the trip current value, set inside. That is, once the current exceeds this threshold, the power will be automatically cut off to avoid potential safety hazards in the car. This maximum current threshold also exists in the household circuit. Once the household's real-time power current value exceeds this threshold, the circuit breaker will trip and cut off the power to avoid potential safety hazards in the home. When new energy vehicles use the home charging method, the trip current value inside the car needs to be coordinated with the household's real-time power current value and the household's maximum current threshold. For example, when the household's real-time power current value is greater than the trip current value, the power needs to be cut off, or when the household's real-time current value is greater than the household's maximum current threshold, the power also needs to be cut off. However, it is difficult for current charging piles to detect the household's real-time current and perform corresponding power-off or current reduction operations based on the trip current value and the household's maximum current threshold.
