Electric vehicle batteries do not need to be fully charged every time and can be charged as needed. Here is relevant information about new energy vehicle batteries: Follow the principle of shallow charging and discharging: Charging from 80% to 100% or from 60% to 80% will not have any negative impact on the battery. On the contrary, frequent deep charging and discharging can accelerate battery degradation. Signs of normal battery degradation: Decreased charging capacity or a significant reduction in range under the same charge level; increased charging time, as battery degradation affects performance, which in turn impacts charging and discharging times; inability to charge the battery to 100%, with charging stopping at around 80% each time.

I've been driving new energy vehicles for five or six years and don't think it's necessary to charge to 100% every time. My daily commute is just over 20 kilometers, and even a full charge only uses part of the battery capacity. Over time, this can accelerate battery aging. I set my phone app to charge up to 80%, which can extend the battery life by several years. I only charge to full on weekends for long trips, since the battery drains quickly on the road anyway. Extra caution is needed when charging in extremely high or low temperatures—cold weather reduces range, while heat damages the battery. Parking in an air-conditioned garage helps. The key is to tailor charging to your daily needs. For city commuters like me, it's about saving power, money, and hassle. Good habits mean a longer-lasting car and a happier wallet.

How to Determine if a Car is Imported?

There are several methods to determine whether a car is imported: 1. Check the brand: Some car brands are exclusively imported, such as Lexus, Porsche, Ferrari, and the Mercedes-AMG series—these can be directly identified as imported vehicles. 2. Examine the model: Brands like Audi, Volkswagen, BMW, and Mercedes-Benz have both imported and domestically produced (joint venture) models. 3. Look at the VIN (Vehicle Identification Number): The VIN, located at the lower right corner of the windshield, starts with 'L' for domestically produced cars, other letters for imported cars, and 'LB' for joint venture vehicles. 4. Inspect the vehicle's nameplate: The nameplate explicitly states the manufacturing location of the car.

What Causes Backfiring in Motorcycle Exhaust Pipes?

The causes of backfiring in motorcycle exhaust pipes are as follows: 1. Overly rich air-fuel mixture: An excessively rich mixture leads to incomplete combustion, leaving a large amount of combustible gas in the exhaust pipe. When this encounters a spark, it results in backfiring, primarily related to the overly rich mixture. 2. Incorrect ignition timing: Slight damage to the ignition system can cause incorrect ignition timing, leading to backfiring in the exhaust pipe. 3. Incorrect valve timing: Wrong valve timing affects the normal opening and closing of valves, which can easily cause backfiring. 4. Mechanical failures: Issues such as broken piston rings or cylinder damage can also lead to backfiring in motorcycle exhaust pipes.

Why does the steering wheel become hard to turn when the car is driving through water?

Steering wheel temporarily becoming hard to turn may be caused by poor contact of the electronic power steering system when it comes into contact with water during wading. Here are the reasons why the steering wheel becomes hard to turn when wading: 1. Water ingress into components: When wading, it's inevitable for car components to get wet. This may cause the hydraulic power steering pump's drive belt to slip when contacting water, resulting in reduced power steering assistance and heavier steering. 2. Electrical circuit failure: Water entering the electric power steering components after wading may cause circuit malfunctions. 3. Water ingress into suspension bushings: Water entering the suspension bushings increases steering resistance. 4. Internal mechanical failure: Water entering the steering gear during wading may cause internal mechanical failures.

What does it mean when the car displays 'check tire pressure'?

When the car displays 'check tire pressure', it indicates a tire pressure warning, meaning that one or more tires have insufficient or excessive air pressure. Below are the effects of both low tire pressure and high tire pressure. Effects of low tire pressure in a car: It increases the friction coefficient with the road surface, causing the steering wheel to feel heavy and the car to pull to one side. The movement of various parts of the tire increases, leading to excessive rolling and abnormal heating of the tire. This reduces the functionality of the cords and rubber, potentially causing delamination or cord breakage. Effects of high tire pressure in a car: It reduces the tire's friction and adhesion, affecting braking performance. It can cause the steering wheel to vibrate or pull to one side, reducing driving comfort. Additionally, it accelerates wear on the central tread pattern of the tire, shortening its lifespan.
