New energy vehicle battery repair technologies are as follows: Imbalance: The repair method involves identifying batteries with consistent capacity, voltage, self-discharge, and internal resistance, then using them together. Sulfation: The repair method involves using the Kedi repair device to desulfate the battery, applying fuzzy digital control theory to measure the battery's state and continuously emit positive and negative variable-frequency microparticle waves during charging and discharging, taking 10 to 20 hours to remove the hardened lead sulfate crystals inside the battery. Plate softening: The repair method involves discharging the battery to 10.5V, then deeply discharging it with a bulb for 1 to 5 hours, followed by activation and repair using an activation device. Short circuit: The repair method for water batteries involves drilling to clean and remove the short-circuited lead powder, while for electric vehicle batteries, a rapid short circuit between the positive and negative terminals can burn out the short-circuited area.

I recently had my new energy vehicle's battery pack repaired, and it seems many owners encounter similar issues. Generally, battery repairs aren't something you can casually DIY—it requires professional shops due to the high-voltage system's electrocution risks, which are extremely hazardous. The shop will use diagnostic computers to check the health of each battery cell. If a module is faulty, they'll replace it or recalibrate the software to balance charging and discharging. The complexity lies in the battery pack being sealed; disassembly requires extra caution for fire and explosion prevention. Repair costs aren't cheap, often running into tens of thousands, so I recommend regular maintenance, like periodically charging to full and discharging once to extend battery life. Also, avoid parking in extreme weather for too long—summer AC use at high power accelerates aging. In short, this concerns driving safety, so don't cut corners at small workshops. It's safer to go to 4S shops or authorized centers since they have full tools and trained staff. Battery repair tech may evolve in the future, but for now, prevention comes first—play it safe.

What is the reason for the car not starting and the dashboard flashing?

Car not starting and dashboard flashing is due to a dead battery. Battery function: When the engine is not started, the battery supplies power to all the electrical devices in the car, and the battery is also responsible for starting the engine. Engine function: The engine can drive the generator to operate, at which time the generator can charge the battery, and the generator can also supply power to the electrical devices in the car. Ignition system operation: The starter needs to operate, the fuel supply system needs to operate, and the ignition system needs to operate. All these systems cannot function without electricity. Precautions: When starting the engine, the battery needs to release a large current. If the battery performance is poor, it may result in difficulty starting the engine or even failure to start.

How many kilometers can one bar of fuel run?

One bar of fuel can run 80 kilometers. Constant-speed fuel consumption refers to the fuel economy indicator when a car is driving at a constant speed on good road conditions. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. The fuel consumption per 100 kilometers indicated in the manuals of domestic cars is generally the constant-speed fuel consumption. However, since cars often experience various working conditions such as acceleration, deceleration, braking, and engine idling during actual driving, the constant-speed fuel consumption is often lower than the actual fuel consumption, resulting in a significant difference. This difference is even more pronounced for cars frequently used for short-distance urban driving.

Can Tar Remover Be Used to Clean Windshields?

Tar remover can clean paint from the front windshield. Methods for cleaning the front windshield: Common stains: For dust and mud commonly found on the windshield, to avoid scratches, first rinse the glass with a car wash water gun. Most of the dust and stains will be washed away, but some water marks may remain, making it look like it's not completely clean. Methods for removing water marks: You can add an appropriate amount of shampoo or other softeners to clean water for washing. After stirring evenly, pour it onto the windshield, then scrub with a cloth or sponge. After cleaning, rinse again with a water gun and dry with a car towel. The glass will become very clean, with no water marks left. Shampoo and other softeners also have anti-static effects, so after washing the glass, they can effectively prevent dust from sticking, keeping the windshield spotless.

Is driving at 56 in a 50 speed limit considered speeding?

Driving at 56 in a 50 speed limit is considered speeding. Here is the relevant information: 1. Relevant regulations: According to the Road Traffic Safety Law, exceeding the speed limit by less than 50% on roads with a speed limit below 60 km/h (not including 60 km/h) will not result in penalty points or fines. 2. Notes: Speeding between 50-55 km/h will result in a warning without penalty points or fines; exceeding 55 km/h will lead to penalty points and fines. Driving at 60 km/h in a 50 km/h speed limit is considered speeding. The setting of speed limits is not solely based on the number of lanes but is determined by factors such as road grade, traffic volume, road width, and the presence of median barriers.

Is It Normal for Car Tire Pressure to Decrease in Cold Weather?

It is normal for tire pressure to decrease in cold weather. Solutions: As temperatures drop, tire pressure values will also decrease. Therefore, it is advisable to appropriately increase tire pressure to avoid excessive movement and abnormal heating of tire components due to over-compression. However, tire pressure should not be too high, as this can reduce tire grip and affect handling comfort. Precautions: Generally, car tire pressure should be checked at least once a month. Pay attention to adjusting tire pressure with each season change. The ideal times for adjustment are November and May. In November, as winter approaches, tire pressure usually decreases and should be slightly adjusted. In May, as the weather starts to warm up, check if the pressure is normal. It is important to note that unless the tire pressure is significantly above the standard range, there is no need to deliberately reduce it. If the tires are not under-inflated, there is no need to adjust the pressure every month.

How Many Kilograms is 4 Liters of Engine Oil?

4 liters of engine oil is approximately 3.48 kilograms, or about 6.8 pounds. The weight may vary slightly depending on the brand of the engine oil. Engine oil, also known as Engine Oil in English, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. Engine Oil Grading: The 'W' in motor oil stands for WINTER. The number before the 'W' indicates the oil's flow performance at low temperatures, with smaller numbers indicating better cold-start performance. The number after the 'W' represents the oil's high-temperature stability, with higher numbers indicating better stability at high temperatures. Winter oil grades include: 0W, 5W, 10W, 15W, 20W, 25W. The 'W' denotes winter, and the smaller the number before 'W', the lower the oil's viscosity at low temperatures, the better its flow performance, and the lower the applicable minimum temperature. API Engine Oil Quality Classification: API engine oils are divided into two categories. One category starts with 'S', indicating oils suitable for gasoline engines, while the other starts with 'C', indicating oils suitable for both gasoline and diesel engines. 'S' category oils: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN. These oils start with 'S', and the letters from A to N indicate progressively higher grades. For example, SN is a higher grade than SM. 'C' category oils: CA, CB, CC, CD, CE, CF. These are general-purpose diesel engine oils, and similar to the 'S' category, the further the letter in the alphabet, the higher the oil's grade. Main Functions of Engine Oil: Lubrication: There is rapid relative sliding between the piston and cylinder, and between the main shaft and bearing. To prevent excessive wear, an oil film must be established between these sliding surfaces. A sufficiently thick oil film separates the sliding surfaces, thereby reducing wear. Auxiliary Cooling: Engine oil has a relatively low specific heat and does not inherently cool the engine. However, during engine operation, heat generated by fuel combustion is carried back to the oil pan by the oil and then dissipated into the air, aiding the radiator in cooling the engine. The actual cooling is performed by water (or antifreeze) outside the engine block. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles back to the oil pan through circulation, cleaning contaminants from the engine parts via the flow of the lubricating oil. Sealing and Leak Prevention: Engine oil forms a seal between the piston rings and piston, reducing gas leakage and preventing the entry of external contaminants. Rust and Corrosion Protection: Lubricating oil adheres to part surfaces, preventing contact with water, air, acidic substances, and harmful gases.
