What is the Principle of On-board Charger for New Energy Vehicles?

On-board charger working principle is as follows: On-board charger power supply: The on-board charger sends a charging request signal to the VCU through the "charging request signal" line of the output port and supplies power to the vehicle controller through the low-voltage power port. If the VCU determines that the battery pack status is suitable for charging, it sends a charging message to the charger, including the requirements for charging parameters. The message content is part of the vehicle communication message. Current control: The power source provides the maximum charging current value to the vehicle controller through the PWM signal. The vehicle controller comprehensively considers the maximum current of the battery pack, the on-board charger, and the charging power source, and selects the minimum value as the current upper limit for this charging session to avoid overcurrent in any of the three components.

Why does the car occasionally shake at idle speed?

Car occasionally shaking at idle speed is mainly caused by the following reasons: engine carbon deposits, aging or carbon deposits on spark plugs, dirty engine throttle, and poor fuel flow. Here are more details on the solutions: 1. Clean carbon deposits from spark plugs or replace them with higher-quality, more expensive spark plugs. 2. If the center electrode of the car's spark plug is made of nickel alloy, it is recommended to replace it every 20,000 to 30,000 kilometers. If both the center and side electrodes of the car's spark plug are platinum or iridium, it is recommended to replace them every 80,000 kilometers, and clean the carbon deposits from the spark plugs when necessary. If only the center electrode of your car's spark plug is platinum or iridium, it is recommended to replace it every 40,000 to 60,000 kilometers.

Are the Vehicle Identification Number and Chassis Number the Same Thing?

Chassis number is exactly the same as the vehicle identification code. The vehicle identification code is also called VIN code, chassis number, commonly known as frame number, seventeen-digit code, etc. It consists of seventeen characters. The VIN code is the ID card of a car, just like a person's ID card, the VIN code of each car is different. Here is more information about the vehicle identification number: 1. The chassis number, which is the vehicle identification code, is a code composed of 17 digits and letters. After permutation and combination, it can ensure that the same car model will not have duplicates within 30 years. 2. The last 6 digits of the chassis number are very significant. Based on these digits, all information about the car can be queried. When you need to handle some business for your car, you only need to report the last six digits to clearly know the model you purchased and the relevant information of the car.

What maintenance should be done for a car at 50,000 kilometers?

Introduction to the maintenance items for a car at 50,000 kilometers is as follows: 1. Replace engine oil and oil filter: Generally, manufacturers recommend replacing the engine oil every 5,000 kilometers or six months. When replacing the engine oil, the oil filter must also be replaced simultaneously, otherwise, it will affect the quality of the lubricating oil. 2. Check whether to replace the brake pads: During the inspection, it is important to note that the thickness of new brake pads is usually around 1.5cm. If the brake pads are worn down to about 0.3cm in thickness, they need to be replaced promptly. 3. Check and replace spark plugs: If there is carbon buildup or black oil stains on the spark plugs, they should be cleaned, and replaced if necessary.

Why is the steering wheel on the right side of cars in Hong Kong?

Because Hong Kong adopts the right-hand traffic system used in foreign countries, the steering wheel of cars is designed on the right side. Below is relevant information about traffic systems: 1. Approximately 90% of countries worldwide implement the right-hand traffic system: Most countries choose to drive on the right side, while some island nations and others drive on the left. Driving on the right is considered safer because, in emergencies, most people instinctively turn the steering wheel to the right. Driving on the right side avoids veering into oncoming traffic lanes, reducing danger. 2. Mainland China has always used the left-hand traffic system: In ancient China, pedestrians, horses, and vehicles generally stayed and moved on the left side of the road, known as "left greeting." When greeting guests, people typically used their right hand for gestures, keeping their bodies on the left. Mainland China has always adopted the left-hand traffic system, so the steering wheel is naturally on the left.
