Wireless charging system for new energy automobile

Abstract

The invention discloses a new energy automobile wireless charging system, which comprises a ground end coupling coil, a power line and an automobile end coupling coil, and is characterized in that theground end coupling coil is arranged at the lower end of a road surface, the power line is arranged at the lower end of the road surface, and the ground end coupling coil is connected with the powerline; the automobile end coupling coil is arranged at the lower end of the automobile; compared with the prior art, a charging wire is omitted, the charging pile has the advantages of being easy to operate, high in safety, high in environment adaptability and the like, charging is achieved during road driving, permanent endurance of a new energy vehicle on a road is achieved, the damage probability is far lower than that of a wired charging pile, and therefore the maintenance cost can be greatly reduced.

Description

technical field [0001] The invention relates to a new energy vehicle, in particular to a wireless charging system for a new energy vehicle. Background technique [0002] my country's new energy vehicles are mainly hybrid vehicles and pure electric vehicles. The charging problem of these two types of vehicles has always been the main obstacle to the development of new energy vehicles. At present, the charging method of new energy vehicles mainly relies on widely installed charging piles. However, charging piles cannot store a large amount of electric energy for the battery in a short period of time, and manual operation is required to connect the charger with the car battery. As a result, car charging not only takes up space , it’s inconvenient, and it’s a waste of time. If you’re running a long distance, the battery life will be insufficient, which will cause trouble for people; dynamic wireless charging is a technology that uses electromagnetic fields or electromagnetic wav...

At present, the charging method of new energy vehicles mainly relies on widely installed charging piles. However, charging piles cannot store a large amount of electric energy for the battery in a short period of time, and manual operation is required to connect the charger with the car battery. As a result, car charging not only takes up space , it’s inconvenient, and it’s a waste of time. If you’re running a long distance, the battery life will be insufficient, which will cause trouble for people; dynamic wireless charging is a technology that uses electromagnetic fields or electromagnetic waves for energy transfer. Inside the road surface, the secondary receiving coil is placed inside the car, and the electric energy is transmitted through the high-frequency magnetic field coupling, so that the new energy car can be charged while driving. Because it is completely insulated, it can avoid the risk of high-voltage electric shock, and its full seal can avoid short circuit and leakage Dangerous, can adapt to a variety of harsh environments and weather, it has no mechanical wear, maintenance-free, easy to automate operations, but the existing dynamic wireless charging system for new energy vehicles has low power conversion efficiency, complex structure, and high cost.
