What is the basic working principle of a battery?

Battery, also known as storage battery, is a type of cell that works by converting chemical energy into electrical energy. Additional information: 1. Generally, what people refer to as a battery is a lead-acid battery. That is, a battery mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte, using lead plates filled with spongy lead as the negative electrode and lead plates filled with lead dioxide as the positive electrode, and using 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, metallic lead is the negative electrode, undergoing oxidation reaction and being oxidized to lead sulfate; lead dioxide is the positive electrode, undergoing reduction reaction and being reduced to lead sulfate. 2. When the battery is charged with direct current, lead and lead dioxide are generated at the two electrodes respectively. After removing the power source, it returns to the state before discharge, forming a chemical cell. Lead-acid batteries are rechargeable and dischargeable batteries, called secondary batteries, with a voltage of 2V. Usually, three lead-acid batteries are connected in series for use, with a voltage of 6V. In automobiles, six lead-acid batteries are connected in series to form a 12V battery pack. Ordinary lead-acid batteries need to be supplemented with sulfuric acid after a period of use to keep the electrolyte containing 22-28% dilute sulfuric acid.

How to Avoid Mistaking the Accelerator for the Brake?

To prevent mistaking the accelerator for the brake, generally, you can avoid such situations by paying attention to the following two points: 1. When driving, you must stay focused, be able to detect situations promptly, and slow down in time after noticing them, trying to avoid sudden braking operations that may lead to mistakes in haste. 2. Whenever you are not accelerating or maintaining steady speed, always move your right foot to the brake pedal. This must become an instinct. (Avoid developing the habit of resting your right foot on the cabin floor when not accelerating, as this may result in failing to locate or accurately press the brake in emergencies, greatly increasing the risk of mistaking the accelerator for the brake).

How Long Should You Wait to Wax New Car Paint?

New car paint only needs waxing after six months. There's no need to wax a newly purchased car too early, as it comes with a protective wax layer from the factory. Waxing too soon can remove this original wax, wasting money and failing to achieve the desired effect—a lose-lose situation. Here are some relevant points about waxing: 1. Depending on the driving and parking conditions, you should decide whether to wax based on actual usage and the local urban environment. 2. Southern regions have rainwater with high acidity and more frequent rainfall, so waxing can be done more often. In contrast, frequent waxing isn't necessary in the north. For cars usually parked in garages, waxing every six months is sufficient. 3. For vehicles parked outdoors exposed to wind and rain, it's recommended to wax every 2–3 months.

How Often Should Car Spark Plugs Be Replaced?

Car spark plugs should be replaced every 30,000 kilometers or every 2 years. Below is relevant information about spark plugs: 1. Prolonged failure to replace spark plugs will affect the car's ignition performance, and long-term use can also lead to carbon buildup. The ignition coil can only provide a limited voltage. Even with normal use, as the spark plug electrodes wear down, the voltage required to bridge the spark plug gap continuously increases. Therefore, during rapid acceleration, high speeds, or heavy loads, misfires may occur, leading to vehicle shaking, difficulty accelerating, and fuel wastage. Thus, spark plugs need to be replaced regularly to keep the engine running at its best, which also helps save fuel. 2. The replacement cycle of spark plugs is directly related to their material. Nickel alloy spark plugs should be replaced every 20,000 to 30,000 kilometers, nickel-yttrium alloy spark plugs every 30,000 kilometers, single platinum spark plugs every 40,000 kilometers, double platinum spark plugs every 60,000 kilometers, iridium spark plugs every 80,000 kilometers, and platinum-iridium alloy spark plugs can last up to 100,000 kilometers before needing replacement.

When to Add Antifreeze?

Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze level regularly and top it up promptly if it is insufficient. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, replace it immediately and clean the system. Types of Antifreeze: Antifreeze is generally categorized into three types: ethanol-water, glycerin-water, and ethylene glycol-water. How to Choose Antifreeze: The key indicators for antifreeze are its freezing point and boiling point. Available antifreeze products in the market come with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Functions of Antifreeze: Antifreeze is non-corrosive and is a specialized coolant containing additives. It is primarily used in liquid-cooled engine cooling systems. Antifreeze provides excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round.

How to deal with driving at 112 in a 100 speed limit zone on the highway?

Driving at 112 in a 100 speed limit zone on the highway means exceeding the speed limit by more than 20% but less than 50%, which results in 6 penalty points. Additionally, drivers who exceed the speed limit by more than 10% but less than 20% will receive 3 penalty points. Drivers who exceed the speed limit by more than 50% will receive 12 penalty points. Below is the relevant information: 1. Highways should indicate the speed limit for each lane, with the maximum speed not exceeding 120 km/h and the minimum speed not less than 60 km/h. On highways, the maximum speed for small passenger cars should not exceed 120 km/h, while other motor vehicles should not exceed 100 km/h, and motorcycles should not exceed 80 km/h. 2. For roads with 2 lanes in the same direction, the minimum speed for the left lane is 100 km/h; for roads with 3 or more lanes in the same direction, the minimum speed for the leftmost lane is 110 km/h, and the minimum speed for the middle lane is 90 km/h. If the speed limit indicated by road signs differs from the above lane speed regulations, drivers should follow the speed limit indicated by the road signs.
