The voltage requirement for new energy vehicle power batteries is to reach 12V or 24V. Related introduction: 1. Lithium batteries: Currently, more and more automobile manufacturers are choosing to use lithium batteries as the power batteries for new energy vehicles. Lithium-ion power batteries have the following advantages: high working voltage (3 times that of nickel-cadmium batteries and nickel-hydrogen batteries); large specific energy (up to 165WH/kg, 3 times that of nickel-hydrogen batteries); small size; light weight; long cycle life; low self-discharge rate; no memory effect; no pollution, etc. 2. Nickel-cadmium batteries and nickel-metal hydride batteries: Although their performance is better than lead-acid batteries, they contain heavy metals and can cause environmental pollution after disposal. Nickel-metal hydride power batteries have just entered the mature stage and are currently the only battery system in hybrid vehicles that has been practically verified, commercialized, and scaled. 99% of the current hybrid battery market share is nickel-metal hydride power batteries, with Toyota's Prius being a representative of commercialization.

Why does the front wheel of Audi A4L make abnormal noise when passing over speed bumps?

Audi A4L front wheel abnormal noise when passing over speed bumps may be due to the power steering belt of the left front wheel making noise; replace the belt. The second type of noise could be from the brake pads or a deformed metal piece behind the brake disc rubbing against it. Other reasons: There are many reasons for front wheel abnormal noise. A rhythmic sharp noise might be caused by friction from the brake pads being too close to the brake disc. Continuous sharp noises could indicate a damaged bearing, while continuous dull noises might suggest an issue with the drive shaft. Normal phenomenon: Some abnormal noises do not affect driving but are merely uncomfortable to hear, such as noises inside the cabin, which are usually caused by loose panels rubbing against each other.

What's the reason for the Audi Q3 not being able to shift gears?

Audi Q3's inability to shift gears may be caused by the following reasons: Failure inside the gear shift lever assembly: The gears inside the gear shift lever are worn out, causing the gear shift lever to get stuck, making it difficult to pull back and forth. As a result, the gear cannot be engaged or it becomes difficult to shift. Failure of the P-gear lock solenoid valve or brake: For safety considerations, to prevent the vehicle from accidentally shifting into other gears when starting, there is this P-gear solenoid valve. This solenoid valve needs to receive the signal from the brake pedal to release. Therefore, these two components are related. As long as one of them fails, it will cause the gear shift lever to be unable to push out from the P-gear and shift into other gears.

What is the horsepower of the Envision 1.5t?

The Buick Envision 1.5t engine has a maximum horsepower of 169 hp and a maximum power of 124 kW. Introduction to Horsepower: Horsepower is a commonly used unit of power measurement in engineering technology, proposed by James Watt. 1 horsepower is approximately equal to 735 watts. It generally refers to metric horsepower rather than imperial horsepower. 1 horsepower equals the work done in 1 second to lift 75 kilograms by 1 meter, also equal to 0.735 kilowatts, or metric horsepower. 1 imperial horsepower equals 550 foot-pounds per second, equal to 76 kilogram-force meters per second, or 0.746 kilowatts. Metric Horsepower: Metric horsepower, also known as metric horsepower, is entirely artificially defined, taking a value very close to imperial horsepower.

What Type of Oil Should a Geely Xingrui Use?

Geely Xingrui is suitable for SAE10W-30 oil. When the ambient temperature is below 0 degrees Celsius, SAE5W-30 can be used instead. The API quality grade should be SL or above. Qualified Lubricating Oil: Only qualified lubricating oil can reduce the wear of engine parts and extend their service life. Qualified lubricating oil must first have good lubrication and wear reduction functions, followed by cooling, sealing and leak prevention, rust and corrosion prevention, and shock absorption. The main differences between synthetic oil and mineral oil are: Synthetic oil can be used over a wider temperature range and has a longer service life, but it is more expensive. For the same oil film requirements, synthetic oil can achieve this with a lower viscosity, while mineral oil requires a relatively higher viscosity to meet the same requirements.

Where is the Audi Q7 fragrance liquid placed?

Audi Q7 fragrance liquid is located in the center console panel area, it is recommended to remove and replace it yourself. Introduction to the fragrance system: The automotive fragrance system is a combination of an in-car fragrance diffuser and automotive fragrance essential oils.

What is the actual fuel consumption of the Huansu S3?

Average fuel consumption is 9.05 liters per 100 kilometers, with a range of 7.83-10.28 liters per 100 kilometers. The following factors affect fuel consumption: Neglecting engine maintenance: Abnormal engine ignition systems significantly impact fuel consumption. Issues like inaccurate ignition timing, leaking high-voltage wires, or spark plug carbon buildup causing weak ignition can reduce engine combustion efficiency and increase fuel consumption. Additionally, poorly maintained engines can see a 10% to 20% increase in fuel consumption, which is considered normal. Using the trunk as storage: Vehicle weight is directly proportional to fuel consumption. It's said that for every 10% reduction in vehicle weight, fuel consumption decreases by several percentage points accordingly.
