How to Solve the Problem of a Battery Not Charging After Long-Term Storage?

Here are the reasons and solutions for an electric vehicle battery not charging: 1. Light sulfation: Perform balanced charging. You can carry out general activation charging (i.e., balanced charging) on the battery, usually lasting one to two days, to restore normal function. 2. Moderate sulfation: Perform "hydrotherapy" charging and discharging. "Hydrotherapy" charging and discharging is required to restore normal function. The specific method involves first adding pure water or dilute sulfuric acid with a density of 1.05g/cm3 to the battery until it reaches a liquid-rich state, then charging with a current of 0.05-0.018C2A for about 20 hours, draining the liquid, and then conducting a capacity test. Repeat the above steps until the battery capacity is restored. 3. Severe sulfation: Use a repair device. If the battery is severely sulfated, ordinary repair methods will no longer work. You can use the high-resistance repair function of a repair device to increase the voltage to above 10V before charging again, which may have a certain probability of reactivating the battery.

What is the truth about the Speedmaster fuel catalyst?

Speedmaster fuel catalyst has some scientific basis for improving car performance, but these metal-rich particles can cause certain damage or effects on spark plugs, three-way catalytic converters, and engines. Benefits of the Speedmaster fuel catalyst: 1. More active fuel molecules: The Speedmaster fuel catalyst can make fuel molecules more active, allowing about 90% of the gasoline to fully combust in the cylinder within a short time. This results in relatively more work done during the explosion stroke, stronger crankshaft power, and increased mechanical energy. 2. Strong anti-knock properties: High-end cars with large cylinder compression ratios require higher-grade gasoline. The Speedmaster fuel catalyst creates a low-temperature working environment inside the engine cylinder, making it less likely for low-grade oil to produce high-temperature thermal compression combustion in high-compression-ratio engine cylinders. The fuel molecules inside the cylinder are more stable and controllable, with strong anti-knock properties. 3. Environmental protection: From an environmental perspective, Speedmaster injects new vitality into automotive fuel. During operation, the fuel's molecular activity is enhanced, allowing for full combustion and significantly reducing the emission of harmful substances in vehicle exhaust, thereby achieving energy-saving and emission-reducing environmental benefits.

What is the fuel tank capacity of the 2012 Highlander in liters?

The fuel tank capacity of the 2012 Highlander is 72 liters, as officially announced. Owners of the 2012 Highlander can also check this information on the vehicle's configuration sheet. The 2012 Highlander requires 92-octane fuel, with a fuel consumption of 9.9 to 12.1L per 100 kilometers. A full tank can cover a distance of 595 to 727 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel gauge accurately reflects the fuel level. The fuel gauge usually has 5 to 6 segments, and it is recommended to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to a safe level, leaving some space from the safe level to the tank opening. This extra space ensures that the fuel can expand safely when temperatures rise without overflowing. If fuel is filled up to the tank opening, the actual refueling amount may exceed the marked tank capacity.

What is the difference between 91w and 94w on tires?

Tire specifications 91w and 94w refer to the tire's load index and speed rating. The number 91 indicates the load index, meaning the tire can bear a maximum weight of 615 kg, while 94 represents a load index of 670 kg. The letter 'w' denotes the speed rating, indicating the tire's maximum speed limit of 270 km/h. Here's an example to illustrate the meaning of numbers and letters in a tire model: 225/60R1799H. 1. 225: Represents the section width, which is essentially the width of the tire tread. 2. 60: Indicates the aspect ratio, referring to the height of the tire's sidewall. 3. R: Stands for the tire type code, with 'R' representing radial tires. 4. 17: Denotes the rim diameter, meaning the tire is suitable for 17-inch rims. 5. 99: Represents the load index, indicating the maximum weight the tire can bear. A load index of 99 corresponds to a maximum weight of 775 kg. 6. H: Indicates the speed rating, showing the tire's maximum speed capability. An 'H' rating means the tire can withstand speeds up to 210 km/h.

Can the All-Wheel Drive System Stay in 4WD Mode All the Time?

No, it does not remain in four-wheel drive mode all the time. The all-wheel drive system only switches to four-wheel drive when necessary, while it remains in two-wheel drive under normal conditions. The system automatically shifts between two-wheel drive and four-wheel drive modes based on the driving conditions. Related information: 1. Types: Mechanical coupling all-wheel drive, electronically controlled multi-plate clutch all-wheel drive, and intelligent electronic all-wheel drive. 2. Advantages: The all-wheel drive system has a simple structure, which effectively reduces costs and helps lower the overall vehicle weight, providing some off-road capability.

What are the contents of the C2 driver's license test?

C1 driver's license test is conducted in the order of Subject 1, Subject 2, Subject 3, and Subject 4. Only after passing the previous subject can you proceed to the next one. The specific test contents are as follows: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. The structure and basic question types of the test question bank are formulated by the Ministry of Public Security, and the traffic management departments of provincial public security authorities establish the test question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject 2: Field driving skills test, including: reversing into a garage, stopping and starting on a slope, turning at a right angle, driving on a curve, and parallel parking. 3. Subject 3: Road driving skills test, including basic test items: preparation before driving (walking around the vehicle counterclockwise, fastening the seat belt, light test, shifting gears, releasing the handbrake, honking the horn), starting, driving straight, changing lanes, passing through intersections, pulling over, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, and making a U-turn. 4. Subject 4: Safe and civilized driving common sense, test items: knowledge related to safe and civilized driving.
