What is the voltage of power batteries in new energy vehicles?

The voltage of power batteries in new energy vehicles is as follows: the working voltage of lead-acid batteries ranges from 2V to 1.8V; the working voltage of nickel-metal hydride batteries ranges from 1.5V to 1.1V; and the working voltage of lithium-ion batteries ranges from 3.6V to 2.75V. Introduction to the Power Battery Management System: The Power Battery Management System (BMS) typically monitors and samples real-time parameters such as individual cell voltage, total voltage, total current, and temperature, and feeds these real-time parameters back to the vehicle controller. In addition to monitoring battery performance parameters and implementing electrical performance management, the BMS also manages the application environment, primarily through thermal management, to heat or cool the battery, ensuring a suitable operating temperature and consistency in the temperature field. Hazards of Battery Management System Failures: If the power battery management system fails, it loses the ability to monitor the battery and estimate its state of charge. This can easily lead to overcharging, over-discharging, overloading, overheating, and increased inconsistency issues, affecting battery performance, service life, and even driving safety.

What Causes the Grounding Fault Display During New Energy Vehicle Charging?

New energy vehicles displaying a grounding fault during charging may be due to the installed grounding bar failing to meet the charging pile equipment requirements. Solutions for grounding faults: If at a public charging station, call the official customer service hotline and wait for repairs, prioritizing other available charging equipment; For residential property owners, it's advisable to contact the property's electrician for troubleshooting; For owners in older residential buildings, first check if the nuts at the grounding device connection are tightened and whether there is any rust. If nuts are loose or rusted, retighten them and remove rust from affected areas to ensure grounding safety. Charging precautions: For new vehicles, completely deplete the battery before the first charge, then charge it fully—preferably for up to 12 hours to enhance battery performance. During regular charging, avoid excessively long charging times; around 7 hours is generally sufficient to prevent battery damage. Prolonged charging may cause the battery to swell. If this occurs, discontinue use immediately to avoid potential hazards like explosions.

Can a new car be shipped by a 4S store or driven?

A new car can be shipped by a 4S store, and vehicle shipping also includes insurance. Document Preparation: When shipping a car, the owner needs to provide a copy of their ID card and vehicle license for company records and inspection during the shipping process. Signing a Contract: A contract must be signed with the shipping company, which must be an official contract with the company's official seal. The contract must clearly state the shipping costs and payment methods to better protect your legal rights in case of disputes. Legal Transportation: During the car shipping process, illegal vehicle transportation is strictly prohibited. Vehicles must not contain flammable, explosive, or controlled items such as knives or guns. Additionally, before signing the contract, the owner should personally inspect the vehicle's interior items and surface condition with the shipping company. Any discrepancies not noted in the contract may result in difficulties claiming compensation for lost items or vehicle damage upon delivery. Clear Value:

Is it better to replace or repaint a scratched new car bumper?

It is appropriate to repaint a scratched new car bumper. If the base coat is not exposed, local polishing will suffice. If the scratch is severe, it is also recommended to have the 4S shop perform a partial repaint to preserve the original paint as much as possible. Methods for car paint repair: Minor scratches can be repaired using a touch-up pen and wax. However, if the paint damage is obvious and reaches the base coat, it is necessary to go to a professional institution for sanding first, followed by spray painting and baking. Generally, an entire panel needs to be repainted depending on the location. Precautions for car paint repair: It is essential to go to a specialized large repair shop or 4S shop for paint repair. Pay attention to the difference between the mixed paint color and the original car paint, and try to use original factory paint or branded paint as much as possible.

Does installing a 360-degree panoramic view system cause significant damage to a new car?

Installing a 360-degree panoramic view system in a new car can cause significant damage as it may disrupt the original wiring of the vehicle. Installing a reversing camera instead allows you to observe the distance between the rear of the car and obstacles while reversing. Components of the 360-degree panoramic system: It mainly consists of four cameras: a front grille camera at the front of the car, two cameras each located below the left and right rearview mirrors, and a rear camera placed near the license plate at the back of the car. There's no need to worry about the installation affecting the car's appearance, as these are discreet installations that are hardly noticeable and do not compromise the overall aesthetic uniformity. Each of these cameras serves a specific function. The cameras under the left and right rearview mirrors are fisheye cameras, providing a relatively wide field of view. The front and rear cameras have a narrower field of view. Usage of the 360-degree panoramic system: The 360-degree panoramic cameras are quite convenient to use. For example, when driving or parking, the system automatically adjusts the camera angles based on the driver's perspective. The screen will directly display the desired field of view for turning, helping the driver see areas that are not easily visible to the naked eye, making it easier to park the car accurately.

How Much Does Fast Charging Affect New Energy Vehicle Batteries?

Fast charging has a significant impact on new energy vehicle batteries. Rapid charging can reduce the battery's cycle life because the battery converts chemical energy into electrical energy, and charging is a reverse chemical reaction. Frequent fast charging can diminish the battery's ability to restore, thereby decreasing the number of charge cycles. The difference between fast charging and slow charging: Fast charging and slow charging are relative concepts. Generally, fast charging refers to high-power DC charging, which can charge up to 80% of the battery's capacity in half an hour. Slow charging refers to AC charging, which typically takes 6 to 8 hours. The speed of electric vehicle charging is closely related to the charger's power, the battery's charging characteristics, and temperature. Portable charging: Portable charging refers to using the portable charging cable that comes with the vehicle to connect to a standard household socket for charging. This is a very convenient charging method, as it allows charging wherever a socket is available. Generally, standard household sockets have a voltage of 220V and a current of 10A, theoretically providing a power of 2.2kW. However, in practical use, the charging power is typically only around 1.5kW.
