Do Charging Voltage and Battery Voltage Require Certification?

Driving an electric vehicle requires a driver's license. Electric vehicles fall under the category of small automatic transmission models, and obtaining a C2 driver's license is sufficient. The C1 driver's license allows driving both small manual and automatic transmission vehicles, while the C2 license is only for small automatic transmission vehicles. When taking the driver's license test, it is important to strictly follow the examination rules, paying attention to details and regulations. Both C1 and C2 require passing the assessments for Subject 1, Subject 2, Subject 3, and Subject 4. Subjects 1 and 4 are written tests, where it is crucial to carefully read and understand the questions (examining the questions) to provide correct answers. The written test portion has no difficult questions; all are multiple-choice questions on laws and regulations. By repeatedly practicing the questions, one can familiarize themselves with the content and correct answers. During the test, it is essential to read the questions carefully and answer attentively. Subjects 2 and 3 involve strict practical operations, requiring adherence to the examination process and planned routes. Pay attention to details: fasten the seatbelt upon entering the vehicle, close the car door, and after the test begins and ends, remember to wait for the system to notify that the test has been passed before unfastening the seatbelt, opening the car door, and exiting the vehicle, among other operations.
To be honest, I've noticed many drivers overlook voltage issues after driving for a long time. If the battery voltage drops below 10 volts, the car simply won't start. And if the charging voltage exceeds 14.5 volts, it can fry the audio or lighting systems. I've experienced several hard starts myself—each time it turned out to be an aging battery. When I checked with a multimeter, the voltage was only 11 volts, and the alternator was charging at just 13 volts, clearly malfunctioning. You don't need any special certification for basic maintenance, but regular checks are crucial. Spending two minutes each month testing can save you the embarrassment of breaking down on the road. I recommend getting a small tool for this. Just make sure to prioritize safety before tinkering—avoid touching exposed wires to prevent minor issues from becoming major failures.
I often do vehicle maintenance myself. Indeed, there's no official certification required for understanding charging voltage and battery voltage—meaning no one asks you to prove your knowledge with a certificate. However, simple testing is essential. I use a multimeter to measure the battery: a full charge should read 12.6 volts, and the alternator output during charging should normally be 13-14 volts. If it's too low, the alternator might be faulty; if it's too high (above 14.5 volts), components can easily burn out. For DIY work, it's safer to disconnect the power before measuring. If you don’t understand something, don’t force repairs—short circuits are a risk. Regular checks can extend battery life by several years and reduce repair costs. If any issues arise, getting an early diagnosis at a professional shop saves both hassle and money.
