Description
Technical Field
The invention relates to the field of new energy vehicle supporting facilities, in particular to a charging pile loss self-checking method and a method for detecting a charging port by using the same.
Background
With the popularization of new energy automobiles, more and more fuel oil owners select new energy automobiles as transportation means for going out, and even buses and engineering vehicles gradually start to step into new energy military; for a new energy electric vehicle, charging is always a hard damage, namely the charging speed of the new energy electric vehicle is not as fast as that of an oil vehicle when compared with the oil vehicle, so that the battery is improved by every large new energy vehicle enterprise, and as for an example of Tesla, a newly developed 4680 cylindrical battery without lugs (full lugs) is improved by 5 times compared with the conventional 21700 cylindrical battery, the vehicle endurance mileage is improved by 16%, the power is improved by 6 times, the maximum advantage of the battery is fast to charge, the battery can be charged to 80% in 15 minutes, due to the application of no lugs, the movement distance of an electronic current in the battery is shortened, the charging speed is improved, 80% of the electronic current before V3 ultra-impulse can be stabilized at a peak value, and the V2 ultra-impulse of a lithium iron battery can not be stabilized at the peak value at present; therefore, when the battery can realize quick charging, the charging pile is required to provide reliable and stable power supply in the next step, and the essence of quick charging is that the current of the charging pile is greatly increased on the premise that the voltage of the charging pile is not changed in a short time, so that whether the plugging between a charging gun of the charging pile and a vehicle charging socket is reliable or not determines whether high-current quick charging can be realized or not; however, the charging gun and the charging interface of the vehicle are inevitably worn in the process of being plugged and pulled for charging for many times, and once the wear is excessive, the charging reliability is directly influenced, and the problems of heating and the like are caused.
According to the above problem, chinese patent CN202011233062.9 discloses a method for detecting wear of a charging opening of a vehicle, comprising: acquiring a first target parameter of a positive electrode line of a charging port, acquiring a second target parameter of a negative electrode line of the charging port, and calculating a difference value between the first target parameter and the second target parameter, wherein the first target parameter and the second target parameter are changed when the resistance of the line where the first target parameter and the second target parameter are located is changed; and judging the difference value between the first target parameter and the second target parameter and the preset target parameter, and reminding a user of detecting the charging gun or the charging seat when the difference value is larger than the preset target parameter.
Although the problem of abrasion detection is solved, it is difficult to see that the abrasion detection is carried out based on the condition that an A pile is matched with an A car (namely, B cars except the A car are not charged in a household state), for a public charging pile, the use of independently recording the abrasion percentage of the last time is not great, and the use of independently recording the abrasion percentage of a charging port of a car is also not great in the same process, because the abrasion is bidirectional, the abrasion can be generated on a charging gun and also can be generated on a charging socket of the car, a new car is matched with an old car, the old car is matched with a new gun, the new car is matched with the new gun and the old car is matched with the old gun, and when different cars are charged, whether the abrasion of the charging port of the car or the abrasion of the charging gun cannot be judged, so that the detection result on the public charging pile hardly plays a reference value; for example, the vehicle a is an old vehicle, the charging gun of the charging pile is a new gun, the actual wear of the charging gun is 0%, the wear of the charging port of the vehicle a actually reaches 80%, and the detected parameter when the vehicle a is charged is a parameter common to both, so the stored first set of wear parameters is 0% of the charging gun plus 80% of the wear of the charging port of the vehicle a, the wear of the charging gun and the charging port is 40% according to the bidirectional wear calculation, the wear recorded by the charging pile is 40% (actually 0%), but the wear amount of the charging port of the vehicle a actually worn 80% is uniformly shared as 40%, and when the next vehicle B is charged, the actual wear of the charging port is 0%, at this time, the charging port of the charging gun or the charging port of the vehicle B is 0 wear, but the wear of the charging pile itself 40% will be a misinformation parameter, which affects the charging of the subsequent other vehicles C, D and E, and the wear parameters completely lose reference meaning under the continuous condition; whether the resistance or the temperature is detected, the detection is carried out under the condition that the charging gun is in butt joint with the charging port, the resistance is increased due to abrasion, the whole circuit is detected under the plug-in state of the charging gun and the charging port, the resistance is increased due to abrasion of the charging gun or the resistance is increased due to abrasion of the charging port cannot be determined, similarly, the detection on the temperature is also carried out on hardware at the contact part of the charging gun and the charging port under the plug-in state of the charging gun and the charging port, the hardware belongs to a heat conductor, the heating position is on the contact surface of the charging gun and the charging port, the heating caused by reduction of the contact area due to abrasion of the charging gun or the heating caused by reduction of the contact area due to abrasion of the charging port cannot be determined, and the purpose of detection on the public charging pile cannot be achieved.
