What Technologies Are Needed for New Energy Vehicle Maintenance?

New energy vehicle maintenance mainly involves three technologies: battery maintenance, drive system controller maintenance, and startup fault maintenance. Battery maintenance technology: First, clearly recognize the important value of battery protection board specifications; second, regularly perform charging and discharging on the battery; third, conduct regular fault inspections to promptly identify and eliminate potential causes of battery failures; finally, ensure the vehicle is turned off and power is disconnected during battery maintenance. Drive system controller maintenance: First, when performing fault detection and maintenance on the drive system controller of a new energy vehicle, power must be disconnected in advance; second, during controller inspection, regular fault checks and troubleshooting must be conducted; third, during controller maintenance, technicians should avoid touching the surface operation buttons and handle dust accumulation properly. Startup fault maintenance: First, technicians can inspect the vehicle's condition to determine the fault location or use advanced instruments for measurement checks; second, after identifying the fault location, technicians need to investigate the cause of the fault to develop more targeted fault elimination measures, improving maintenance efficiency and precision.

Is It Dangerous to Keep Alcohol Wipes in the Car?

Keeping alcohol wipes in the car is not dangerous. Alcohol wipes can be stored in the car, but the following points should be noted: 1. Maintain ventilation: Ensure proper indoor ventilation, as a high concentration of alcohol vapor in a confined space can easily cause a fire. 2. Avoid direct sunlight: In summer, prolonged exposure to direct sunlight can raise the temperature inside the car to 60-70 degrees Celsius. When exposed to prolonged sunlight or when the temperature inside the car reaches a certain level, alcohol-containing items like wipes can easily expand and explode, leading to a fire. 3. Avoid bulk purchases: Do not purchase large quantities of alcohol, as storing excessive amounts can pose safety hazards.

What are the benefits of driving on highways for a car?

Driving on highways benefits the vehicle by helping to remove carbon deposits. Frequent driving in urban areas with frequent traffic congestion can lead to carbon buildup in the car. However, when driving on highways, the engine operates at higher RPMs, allowing for more complete combustion of gasoline, which results in less carbon deposits. Here are some additional details: 1. The principle of carbon deposit formation: The pistons in the engine do not operate synchronously. When the vehicle is turned off, the intake valves of the engine's cylinders do not close simultaneously, and the gasoline injected during the current working cycle cannot be recovered in time. Some unburned fuel continues to evaporate and oxidize, forming softer black carbon deposits in the intake pipe, especially behind the throttle valve. 2. Benefits of highway driving: Frequent highway driving can utilize the engine's high-speed operation to flush the fuel system and carbon deposits. Long-term high-speed driving allows for more complete fuel combustion, reducing fuel consumption and minimizing carbon deposit formation. The engine can rotate more fully, and the engine oil can better perform its lubricating function.

Is Crack Repair Glue Effective for Headlights?

Headlight crack repair glue is not effective. Due to flying stones or scratches during driving, car headlights may develop scratches, and minor scratches can be repaired. Repair methods: Toothpaste Polishing: For fine scratches on car headlights, toothpaste can be used for polishing. Toothpaste contains abrasive particles. Apply toothpaste to the headlight, then use a clean towel to polish in circular motions before rinsing with water. Toothpaste is somewhat effective for minor scratches but has little effect on larger ones. Polishing Repair: For longer scratches and cracks on car headlights, fine-grit sandpaper can be used for sanding, followed by polishing with polishing wax. The principle is similar to paint polishing. Fumigation Repair: This method uses a heater with alcohol as a volatilizer. Specialized and processed materials are then attached to the headlight surface via steam to fill in the scratches, followed by sanding to achieve the repair effect. This method is equivalent to coating, and the repair can last up to about two years.

What is a Transferred Vehicle?

Vehicle transfer refers to the change of ownership of a vehicle. Below is an introduction to the relevant content of vehicle transfer: 1. Documents required for vehicle transfer: original owner's ID card, new owner's ID card, original or copy of the vehicle's license, purchase tax certificate, proof of payment of vehicle and vessel use tax, motor vehicle registration certificate, motor vehicle criminal inspection report, insurance policy, card or invoice. All of these must be provided in original. 2. Household registration: Each vehicle has a fixed household registration, just like a person. The vehicle's household registration mainly records the owner and address of the vehicle, as well as some relevant vehicle parameters. A transferred vehicle proves that the vehicle belongs to the new owner and has no accidents or violations. When there are issues with the vehicle, such as accidents, failure to participate in annual inspections, stolen vehicles, or smuggled vehicles, the transfer cannot proceed through normal procedures.
