What Causes the Humming Sound After the Chassis is Scraped?

The vehicle chassis inherently possesses certain impact resistance. If it's only a minor scrape, it typically won't affect the vehicle's performance. However, during high-speed driving, if the chassis scrapes against hard and sharp objects like rocks or sharp tools, it can cause damage such as denting the chassis steel plate, deformation of the suspension structure, or even damage to the steering mechanism, leading to severe consequences. Below are aspects of chassis maintenance: 1. Hazards: Poor chassis maintenance can result in issues like vague steering, oil leaks, and loosening of the overall framework, posing safety risks. 2. Precautions: Maintenance should first focus on checking for rust, as the chassis is directly exposed to rainwater and dust, working in harsh conditions that make it prone to rust. If the chassis is rusted, protective measures such as rustproofing and applying protective paint should be taken.

What is the power of home charging for electric vehicles?

Charging piles are divided into two main categories: AC piles and DC piles. Generally, AC piles have a power of 7KW and use a 220V single-phase power supply. DC piles come in various power levels such as 30KW, 60KW, 100KW, 150KW, and 200KW. The actual charging power is determined by the matching result between the electric vehicle's battery parameters and the charging pile, and it varies with the charging state. Precautions for charging electric vehicles: 1. Pay attention to charging time: Correctly grasp the charging time, which is generally around ten hours for battery charging. Plan charging in advance before traveling to avoid running out of power during the trip. 2. Good charging environment: Protect the charger and try to avoid bumps and vibrations. Keep the area ventilated during charging, otherwise, it may affect the battery life. 3. Charge daily: It is recommended to charge every day to keep the battery in a shallow cycle state, which can extend the battery's lifespan.

Why Can't the Electric Car Key Unlock the Door?

The reasons why an electric car key cannot unlock the door include electronic lock damage, remote control damage, or insufficient battery power in the remote control. Here are the detailed explanations: 1. Electronic lock damage: If the electronic lock is damaged, it cannot receive the unlock signal or fails to initiate unlocking even after receiving the signal, resulting in the inability to unlock the electric car. In this case, repair is necessary. 2. Remote control damage: If the remote control cannot emit signals, it will lead to unlocking failure. Generally, two remote controls are provided when purchasing an electric car, and the spare remote control can be used. 3. Insufficient battery power in the remote control: Weak signals emitted due to low battery power in the remote control can cause unlocking failure.

What Are the Reasons Why the Ignition Device Cannot Start the Engine?

The reasons why the ignition device cannot start the engine are as follows: 1. The battery cannot hold a charge: If the vehicle has no power after being parked for just 1 day, aside from the battery's own sulfation (which prevents charging), it may be due to a leakage in the vehicle's wiring harness. 2. Short circuit in the coolant temperature sensor: If the engine fails to start after multiple attempts and the spark plug electrodes are very clean, it may be due to a short circuit in the coolant temperature sensor. 3. Clogged fuel filter: While driving, the vehicle's speed suddenly drops and continues to decrease until the engine stalls. After stalling, restarting may allow the engine to start, but the speed remains very low, and the engine cannot maintain operation, eventually stalling again and failing to restart. 4. Anti-theft system lock: When the anti-theft system is locked, the steering wheel cannot be turned, and the anti-theft indicator on the dashboard lights up. The control unit will interrupt fuel supply control but not the ignition. The engine cannot start, indicating that the steering wheel and ignition switch are locked by the central control. Applying force to rotate the steering wheel until it moves will cause the anti-theft system to automatically unlock, allowing normal startup.

Where are the reference points for reverse parking?

The reference points for reverse parking are as follows: 1. The steering wheel turning point: When the left rearview mirror aligns with the starting line (usually indicated by the instructor), immediately turn the steering wheel to the maximum. 2. Direction correction reference points: (1) As the vehicle is about to enter the parking space and the rear compartment approaches the parking line, observe through the rearview mirror to maintain a horizontal distance of approximately 30 centimeters between the wheels and both sides of the parking space. Adjust if the distance is too wide or too narrow. (2) After the vehicle enters the parking space, observe the left rearview mirror and the edge line of the parking space entrance. When the lower edge of the left rearview mirror aligns with the edge line of the parking space entrance, and when the edge line just disappears from view under the left rearview mirror, press the clutch and brake, stop the vehicle, and the reverse parking is completed.

What are the symptoms if one reversing radar is broken?

If one reversing radar is broken, it will not affect the entire system; only the broken one will not beep, while the other reversing radars will still function normally. Since the four probes of the reversing radar operate independently, if one is damaged, only the faulty reversing radar needs to be replaced. Below is some relevant information: 1. Probe positions: A reversing radar typically has four probes, installed on the rear or both sides of the car, with two on each side. 2. Overview: The reversing radar, also known as a reverse collision avoidance radar or parking assist device, is a safety aid for parking or reversing. It consists of ultrasonic sensors (commonly called probes), a controller, and a display (or buzzer). The reversing radar system alerts the driver to surrounding obstacles through audible signals or more intuitive visual cues, making reversing and parking safer.
