48V mild hybrids do not require battery replacement because the engine can automatically recharge the electric motor while the vehicle is in motion. However, if the motor is damaged or the battery is depleted due to special circumstances, the battery will need to be replaced. The 48V circuit is responsible for supporting the active chassis system, air conditioning compressor, and regenerative braking system. The 48V mild hybrid system primarily consists of three core components: the torque-assist recovery motor, power conversion unit, and power battery. In this system, the electric motor hardly participates in directly driving the vehicle but serves as a tool for energy recovery to assist the engine. This allows the vehicle's electrical equipment to minimize reliance on the engine, enabling the engine to drive the vehicle more efficiently.

How to Install New License Plates?

Method for installing new license plates: After receiving the license plates, there is usually a pack of secure screws included. Take out the screws, insert them into the anti-theft caps while rotating, then position the license plate correctly. Align the screws with the four gaps on the bumper and secure them with a Phillips screwdriver. After tightening, cover the anti-theft caps and press them gently into place. License plates, commonly known as vehicle plates, are panels hung on the front and rear of a vehicle. They are typically made of aluminum, sheet metal, plastic, or paper, and display the vehicle's registration number, registration region, or other relevant information. License plates serve to number and record information for each vehicle, allowing identification of the vehicle's region of registration and enabling the lookup of the vehicle's owner and registration details based on the plate.

How to Use Automatic Headlights?

Automatic headlight usage method: Simply turn the light control knob to the auto position. Automatic headlights, also known as auto-sensing headlights, are equipped with a photosensitive control system for the front lights. The central intelligent control box determines the change in light brightness through the light sensor, thereby controlling the automatic switching on or off of the headlights. Automatic headlights only function when the light control is set to the auto position. The main purpose of headlights is to illuminate the road ahead and to alert pedestrians or other vehicles to the presence and position of your vehicle. Therefore, automatic headlights can activate when ambient light is insufficient, ensuring driving safety.

How to Clean Cement Splashed on the Car?

Methods for cleaning cement splashed on the car: Cement is somewhat corrosive and can damage the car's paint, so it should be dealt with promptly. If the cement has not yet hardened, you can wet it with clean water, rinse it off, and then use a towel with cleaning solution to wash it away. If the cement has already solidified and hardened, white vinegar can be used for cleaning. White vinegar is an acidic liquid that can effectively dissolve cement. Pour white vinegar onto the cement attached to the car, wait a few minutes for the cement to soften, and then it will be much easier to clean. Generally, multiple cleanings are required to thoroughly remove the cement. During the cleaning process, be meticulous and patient, avoiding any rough scrubbing or scraping to prevent damage to the car's paint.

How to Deal with Foggy Windshield?

Press the defogging button, turn on the air conditioning (A/C) switch, set the temperature to the lowest, and turn on the external circulation to defog. Foggy car windows can be cleared by using either cold or warm air, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days, as it will initially increase the fog. When the car windows fog up, turn on the external circulation. The reasons for foggy car windows: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface of the side with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on in time, the humidity of the exhaled air is high, and the windshield will quickly fog up. At this time, turn on the air conditioning to blow cold air onto the windshield, using the dehumidifying function of the air conditioning to quickly remove the fog on the windshield. However, if the humidity is too high and the air conditioning is not effective enough, you can slightly open the window to quickly reduce the humidity inside the car. Of course, it can also be used in combination with the air conditioning for faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, use warm air to blow hot air onto the glass, quickly raising the temperature of the front glass and reducing the temperature difference between the inside and outside surfaces of the window glass, which can prevent excessive fogging of the front windshield in time. However, it should be noted that the temperature of the rear and side windows rises slowly, so it takes longer to remove all the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification; the temperature control of the air conditioning should not be set to the coldest position, otherwise, the outer surface of the windshield may fog up after prolonged use. Spraying Anti-Fog Agents for Prevention: Spray a small amount of anti-fog agent on the car windows and wipe it clean to remove dirt and stains from the windows. While polishing the glass, a thin transparent protective film is formed on the glass, which effectively prevents the condensation of water vapor on the glass and the formation of fog, especially suitable for cold winters. Alternatives to anti-fog agents include dishwashing liquid, soapy water, glycerin, alcohol, or saline solution. After drying, use chamois or a soft dry cloth to wipe off excess fibers, which can ensure that the car windows do not fog up for several days. Opening Windows for Convection: If the fog inside the car is not heavy, you can open the windows on both sides to create convection between the inside and outside air, reducing the temperature difference, and the fog will slowly disappear. The principle of this method is the same as using cold air from the air conditioning. The drawback of opening windows for convection is very obvious: it cannot be used in rainy or snowy weather, on highways, or when the fog is heavy. Rear Windshield Heating: Most cars basically have a rear windshield electric heating function, although the button positions may vary, the functions are the same. Turn on the windshield heating switch, and the fog on the rear windshield will disappear in about a minute.
