Abstract

The invention relates to a reverse pantograph, a charging system and a car. The reverse pantograph comprises a pantograph head, the pantograph head comprises one or more pantograph positive pole plates used for being crossed with positive pole plates of a collector-shoe gear of the car during charging contact, and one or more pantograph negative pole plates used for being crossed with negative pole plates of the collector-shoe gear of the car during charging contact. A positive pole and a negative pole on the pantograph head of the pantograph are correspondingly crossed with and are in buttingcontact with a positive pole and a negative pole of the collector-shoe gear of the car; and in the charging process, the errors in the front, rear, left and right directions of the actual parking position of the car are within the allowable range, the positive pole plates and the negative pole plates of the pantograph can reliably make contact with the positive pole plates and the negative pole plates of the collector-shoe gear correspondingly, thus the precision requirements for the positioning and parking position of the car are lowered, it is ensured that charging is conducted normally, the contact form that the pole plates are arranged in a crossed mode is utilized, the current carrying area is increased, and high-current and high-power charging is ensured.

Description

technical field [0001] The invention relates to a reverse pantograph, a charging system and an automobile, and belongs to the technical field of electric vehicle charging. Background technique [0002] At present, in the world and Chinese markets, with the continuous promotion and popularization of new energy vehicles, their ownership is increasing year by year. According to the forecast of the Ministry of Industry and Information Technology's energy-saving and new energy vehicle technology roadmap, it is estimated that the number of new energy vehicles will reach 5 million in 2020, and the number of new energy vehicles will be close to 20 million in 2025. [0003] Traditional electric vehicles usually use manual plugging and unplugging of the charging plug for charging operations. The user needs to manually take out the gun head and connect it to the socket of the vehicle to be charged, and then operate the charger to start the charging process. After the charging is comple...
