It's time to ask what industry is stable and fragrance. Car maintenance is a priority! After all, there are more than 300 million cars in the country, and new energy cars alone account for 1 in 10, and the maintenance needs behind this are not covered. But now it's not as simple as it used to be to screw screw up oil, so let's just talk about what we're learning today in auto maintenance and why is it a "older, more valuable" technical job。
What exactly do you learn from “iron puss” to “high-tech”
Car maintenance is no longer what you think it is. It's more like a "cross-border complex" player who knows the mechanics of conventional fuel cars, who play high-tech with new energy cars, and who keeps up with the growth of smart internet-connected cars. In short, the profession is divided into three main sections: basic theory, practical skills, new technology expansion, and, finally, an “official certification” for entry。
Ii. From class to workshop, you must know these courses
(i) basic theory course: grounding and building of buildings
Don't think autopsies are just work. Theoretics is the "methodology". For example:
Automobile construction and principles: how does the engine work? How did the gearbox change? What happened to the brake system? This has to start with the principles. Students at the university of the sea technicians said that they had to understand even the “car computer (ecu)” and “can bus communication system”。
Mechanical mapping and material science: it is essential to understand the drawings of auto parts and to know how metals and plastics are applied in cars, even for the exclusive use of new energy vehicles, such as battery casings。
Electrotechnologies: the cars are now “electronic control”, from light to engine, without an electrical base, not even a circuit map。
(ii) practising skills course: from screws to diagnostics
Theoretics are over. This part is divided into two parts:
Maintenance of conventional fuel trucks:
Mechanical maintenance: engine dismantling, speedbox failure diagnosis, brake system maintenance, which must be well developed. For example, the transformer needs to know when to switch to the clutch, when to switch the hydraulic system。
Electrical detection: sensor data are viewed with oscilloscopes and fault codes are read with diagnostics (e. G., metagraph x431). The teacher said that the era of repairing cars was over and had to be based on data。
New energy motors:
High-pressure safety protection: new energy vehicle battery voltage is over 300 v, after learning “insulation tool use” and “emergency power outage operation”, safety first
Three electrical systems maintenance: battery detection, failure screening of electrical controllers, maintenance of charge stakes. For example, a sudden decline in the continuation of the battery, with specialized equipment to measure the “cell health” (soh), whether the individual core is broken or the overall decay。
Smart diagnostic techniques: tesla and biadi vehicles have their own specialized diagnostic systems and are required to learn the maintenance process for brand certification。
(iii) new technology expansion: smart web, second-hand car assessment, wider skills learning
Now, the auto mechanics are following industry trends, for example:
Smart internet-connected vehicles: learn how to fix a vehicle-mounted network system, such as v2x technology, and fix cars by learning how to connect a car to a mobile phone。
Second-hand car assessment and insurance loss: the repair of cars alone is not sufficient, and it is “validation” or loss for insurance companies, which is “cross-border skills”。
Entrepreneurship and management: if you want to open your own business, you have to learn to manage the “parts marketing” of “car repair businesses” and even “customer complaints processing”。
(iv) official certification: without it, no 4s will let you in
Car repair is also entitled to a “licensed induction”, and the strongest is the ministry of human welfare's certificate of profession profession professional professional profession, secondary, advanced, technician, senior technician. What are you asking for? For example:
(b) primary work: after one year of relevant work or after apprenticeship。
Secondary workers: four years after obtaining a primary certificate, or six years cumulatively。
Senior workers: those who have completed five years of service after obtaining a secondary certificate or have advanced technical/secondary education。
In addition, a motor vehicle survey maintenance engineer (licensed by the ministry of transport and communications) is required to enter the 4s store, and a low-voltage work certificate (licensed by the ministry of emergency management) is preferred for the repair of new energy vehicles. The branders also have their own certifications, such as tesla certification technician and german tÜv diagnostic engineer, which can raise wages a lot
Iii. Conclusion: why does a car repairs work as an iron job
Now cars are becoming more intelligent and maintenance techniques are “upgraded”. A conventional fuel truck has to be mechanical, a new energy car has to be electric, and a smart network has to be software. State policy is also being pushed forward, for example, by the state council’s recently issued document, which calls for “three years to train 30 million skilled people”, focusing on areas such as advanced manufacturing, the digital economy, and so on。
More critically, the line “thresholds are progressing and demand is soaring”. There is now a huge gap in the number of new energy vehicle maintenance personnel, and one and a half times the wage of a head enterprise cannot be hired. So, learning to fix cars is not “eating for youth”, but “ getting older and worth more” — the more experienced, the better the diagnosis of failure, the more trust the client trusts, and the higher the wages。
Finally, the truth is: the auto mechanics are already a complex technology of "mechanic + electronics + software". In order to do so, we have to be prepared for “life-long learning”, but the returns are also attractive — from junior technicians to technocrats, with annual pay doubling. So, if you're interested in cars and you're not afraid to think about it, it's worth thinking about
