Does fast charging harm electric vehicle batteries?

Currently, the batteries commonly used in electric vehicles are mainly lithium batteries and lead-acid batteries. Different battery types have distinct power generation mechanisms and exhibit significant differences in sensitivity to fast charging. For lead-acid batteries, the internal electrolyte gradually reacts and depletes during charging, ultimately leading to a gradual reduction in battery capacity and decreased driving range. Although slow charging also causes battery capacity reduction, the process is slower and results in minimal damage. Lithium batteries: During fast charging, a large current is instantly input into the battery, which affects its recovery capability. Reduced recovery capability accelerates battery degradation and decreases the number of charge-discharge cycles, thereby impacting the battery's range and overall performance. Battery Management System: Generally, factors such as battery density, materials, and temperature in electric vehicles influence fast charging speed and the extent of battery damage. Electric vehicles are typically equipped with a Battery Management System (BMS), whose primary function is to regulate the current and voltage input during charging. It accurately predicts the state of the power battery pack and maintains the charging temperature within a specific range to avoid excessive battery damage.

Is it mandatory to use 0w20 engine oil for the Magotan China VI model?

The China VI-compliant Magotan models must use 0w20 engine oil. This type of oil helps prevent the generation of ash particles after combustion, which could clog the particulate filter. The oil contains almost no additives, allowing oil vapor to enter the combustion chamber through the crankcase ventilation port during engine operation. The resulting carbon ash particles can then be regenerated by the particulate filter installed behind the three-way catalytic converter. The new Magotan is equipped with 1.4T and 2.0T turbocharged engines in high and low power versions, all meeting China VI emission standards. It is paired with a 7-speed dual-clutch transmission for automatic gear shifting, ensuring convenient operation. The high-power 2.0T engine delivers a maximum output of 162kW and a peak torque of 350N·m, achieving a 0-100km/h acceleration time of 7.2 seconds and a combined fuel consumption of just 6.6L/100km as per the MIIT standard. The chassis features an independent suspension system with front MacPherson and rear multi-link setups, combined with Volkswagen's excellent chassis tuning technology, striking a balance between comfort and handling.

How to Solve the Low-Frequency Resonance Caused by Accord Leading to Tinnitus?

The solution to the low-frequency resonance caused by the Accord leading to tinnitus is to install high-efficiency soundproofing cotton for noise reduction. Below are specific details about low-frequency resonance in cars: 1. When low-frequency resonance occurs in a car, the vehicle idles or drives at low speeds, and continuous low-frequency resonance inside the cabin causes discomfort to the driver and passengers, with severe cases even leading to dizziness, vertigo, and nausea. Due to the thin metal and plastic panels in mid-to-low-end cars, external noise can penetrate. Installing thickened soundproofing panels can block the noise. The car body's design inherently avoids overlapping the car's natural frequency with the engine's frequency. However, due to wear and tear from usage, the car's natural frequency changes, causing resonance at a new speed. 2. For low-frequency resonance in cars, it is recommended to use white sound-absorbing cotton (white cotton, Sherry cotton, microfiber cotton) for soundproofing materials, as it can effectively absorb low-frequency noise bands generated externally or internally. As for vibration damping panels, there are two types: asphalt and butyl rubber. Although both can eliminate low-frequency noise in cars, butyl rubber is preferred because asphalt vibration damping panels emit toxic gases such as formaldehyde and toluene at high temperatures, which significantly impact human health.

How to Carry a Baby in a Smart Two-Seater?

To carry a baby in a Smart two-seater, you only need to properly use restraint devices such as a safety cradle, safety seat, or safety booster seat. However, please note the following: 1. Cannot sit in the front passenger seat: According to the law, children under 10 years old are not allowed to sit alone in the front passenger seat. 2. Sit in the rear seat: Sit in the rear seat and install restraint devices. Here is some information about the Smart two-seater: 1. Body dimensions: The overall length is only 2500mm; the curb weight is only 730kg. 2. Powertrain of the new model: Equipped with a 0.9T three-cylinder turbocharged engine, delivering a maximum power of 90 horsepower and a maximum torque of 135 N·m. The existing model is equipped with a 1.0L naturally aspirated engine, producing a maximum power of 71 horsepower and a torque of 91 N·m. The new model features a 6-speed dual-clutch transmission.

At What Tire Pressure Should You Inflate?

Typically, you need to inflate when the tire pressure is below 2.4 bar. The hazards of low tire pressure include: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causing the steering wheel to feel heavy and making the vehicle prone to drifting, which are factors detrimental to driving safety; Increasing the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire; Reducing the functionality of the cord and rubber, causing delamination or cord breakage, and excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Exponentially increasing friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a blowout; Increasing tire body deformation, making the tire side prone to cracking, and generating flexing movements that lead to excessive heat, accelerating rubber aging, fatigue in the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulder.

What to Do with TPMS When Changing Wheels?

After changing the wheels, simply replace and reset the tire pressure monitoring sensors. Tire pressure monitoring is a system that automatically monitors tire pressure in real-time while driving, alerting the driver to leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct TPMS: Direct TPMS uses pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the data for each tire. The system automatically alerts when tire pressure is too low or if there is a leak. Indirect TPMS: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect TPMS essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both direct and indirect systems. It is equipped with direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a full direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a direct system.
