The green light stays on due to damage in the sampling circuit composed of a voltage regulator tube and a transistor, causing the system to detect the battery voltage as normal or fully charged. Below is relevant information about the Wuling Hongguang Mini's battery: 1. Battery Safety: The Hongguang MINIEV's power battery is backed by robust technology, ensuring multiple layers of safety protection. It features low-temperature preheating technology and battery insulation functions, and has undergone 16 rigorous safety tests. With dust and water resistance reaching IP68 level, it effectively addresses issues like reduced winter range and harsh weather conditions, ensuring safe charging and driving. 2. BMS System: Equipped with a BMS intelligent battery management system, it allows real-time monitoring of battery status via a mobile app, providing users with comprehensive high-level safety protection.

Recently, while driving my Wuling Hongguang Mini, I encountered a situation where the green light stayed on during charging. This is usually a normal signal indicating that charging is complete, as the design specifies that a steady green light means the battery is full. Don’t worry, this isn’t a malfunction. If the green light is on but the car isn’t charging, it might be due to a loose charger connection or aging cables causing looseness—try unplugging and re-plugging it. In daily use, a steady green light after charging should be energy-efficient and safe, but remember to regularly check the battery’s health, such as monitoring progress via a mobile app or inspecting the charging port for dust monthly to prevent poor contact. From my experience, a continuous green light indicates everything is normal; if there’s an abnormality, then visit a service station to check for circuit issues.

Do You Need to Use Turn Signals During Curve Driving in Subject 2?

During curve driving in Subject 2, it is not necessary to use turn signals. There are a total of 6 situations in Subject 2 where turn signals are required, which are: When starting the vehicle, turn on the left turn signal; When starting on a slope, turn on the left turn signal; During parallel parking, turn on the right turn signal when the vehicle passes the parking spot and stops 30 cm away from the curb, preparing to reverse; Before shifting into reverse gear during parallel parking, turn on the left turn signal because the steering wheel will be turned fully to the right during reversing, causing the front of the car to shift left; Before exiting the parking spot during parallel parking, shift into drive gear and turn on the left turn signal, then turn it off promptly after exiting; When entering the right-angle turn area, turn on the left turn signal and turn it off promptly after completing the turn. Penalties for incorrect use of turn signals are as follows: Failing to use or incorrectly using turn signals before starting, turning, changing lanes, overtaking, or parking will result in a 10-point deduction. Turning the steering wheel within 3 seconds of activating the turn signal before starting, turning, changing lanes, overtaking, or parking will result in a 10-point deduction. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for small vehicles C1 and C2 include reversing into a parking space, parallel parking, slope parking and starting (canceled for C2), right-angle turns, and curve driving (commonly known as S-curves) as mandatory items (some regions also include a sixth item: highway toll card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include pole test, slope parking and starting, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, narrow gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turns, as well as simulated highway driving, continuous sharp mountain road turns, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling.

Is the Exhaust Tip Covered Under Warranty?

Exhaust Tip Covered Under Warranty. Introduction to Exhaust System: The automotive exhaust system primarily discharges waste gases produced by engine operation while reducing pollution and noise levels from the emitted exhaust. Vehicle exhaust systems are mainly used in light-duty vehicles, compact cars, buses, motorcycles, and other motor vehicles. Emission Reduction Methods: To reduce noise at its source, it is essential to first understand the mechanisms and patterns of noise generation. This can be achieved by improving machine design, adopting advanced manufacturing processes, minimizing excitation forces that cause noise, reducing the response of noise-producing components to these forces, and enhancing machining and assembly precision.

This method requires no car disassembly or screw removal, making it simple and convenient. The purpose of the automatic door lock is anti-theft, as it activates only after the vehicle reaches a certain speed (approximately 15 km/h), preventing door pull robberies during traffic jams or at red lights, thereby providing a certain level of security. The CRV is a classic urban SUV model produced by Dongfeng Honda. In terms of body dimensions, it measures 4550mm in length, 1820mm in width, and 1685mm in height.

What are the set pressure and discharge pressure of a safety valve?

Safety valve set pressure, unless otherwise specified by the process, is 1.10 times the normal working pressure, with a minimum of 1.05 times. Function of safety valve: A safety valve is a protective valve whose opening and closing components remain normally closed under external forces. Discharge pressure: For steam safety valves, the discharge pressure should be less than or equal to 1.03 times the opening pressure; for air or other gases, it should be less than or equal to 1.10 times the opening pressure; for water or other liquids, it should be less than or equal to 1.20 times the opening pressure.
