What is the impact of not fully charging a new energy vehicle battery each time?

Not fully charging a new energy vehicle battery each time will shorten its service life. Battery lifespan: Generally, lead-acid batteries can undergo about 360 full charge-discharge cycles, while lithium batteries can handle around 520 full charge-discharge cycles. Therefore, unplugging the charger before the battery is fully charged will prematurely consume charge-discharge cycles, reducing its lifespan. For example, an electric vehicle battery that could originally last 3 years might only last 2 years or even shorter if frequently unplugged before full charge. Charging precautions: Regarding charging time, for a newly purchased electric vehicle, the first charge is best done for up to 12 hours to fully activate the battery performance. During regular charging, avoid excessive charging time; generally, 6-8 hours is appropriate.

Why does the BYD Song make a noise when shifting gears and releasing the clutch?

The reason why the BYD Song makes a noise when shifting gears and releasing the clutch is that the clutch pedal return spring lacks lubricating oil. Adding lubricating oil to the return spring can solve the problem. The functions of the clutch are: 1. Gradually increase the driving force of the car to allow smooth starting; 2. Temporarily separate the engine and transmission for gear shifting; 3. Prevent overload of the transmission system; 4. Reduce torsional vibration impact from the engine and extend the service life of transmission gears. The working principle of the clutch is: 1. When the inner ring is fixed, the outer ring rotates clockwise and the wedge block does not lock, allowing the outer ring to rotate freely; 2. When the outer ring rotates counterclockwise, the wedge block locks, preventing the outer ring from rotating.

Is Mobil 2000 a Full Synthetic Oil?

Mobil 2000 is not a full synthetic oil, but a semi-synthetic oil. The functions of engine oil are: 1. As a lubricant, it reduces friction and wear between moving parts; 2. As a coolant, it absorbs heat generated in the engine combustion chamber and piston top, cooling the engine and preventing overheating; 3. As a sealant, it fills the gap between piston rings and cylinder liners to prevent combustion pressure leakage. The oil change process is: 1. Remove the drain plug to drain the used oil; 2. Remove the oil filter; 3. Clean the filter housing and replace the oil filter element; 4. Add new engine oil; 5. Check for any oil leaks.

What to Do If You Get Counterfeit Gasoline?

If you have filled your car with counterfeit gasoline, the solution is to replace the engine oil and oil filter, and clean the oil passages. Here are some precautions to take when refueling: 1.

Avoid spilling fuel on painted surfaces to prevent damage. 4. If the fuel door is frozen and cannot be opened, gently push or tap the fuel door to remove the ice and open it. 5. Prevent excessive fuel pressure that could lead to spraying. 6. Insert the fuel nozzle deep into the fuel tank to avoid overflow or splashing, which could cause fire or explosion. 7. Before opening the fuel filler cap or touching the fuel nozzle, touch the car body to discharge static electricity. Avoid re-entering the vehicle while refueling to prevent static electricity buildup.
