What are the reasons why the battery of Wuling Zhiguang cannot be charged?

Wuling Zhiguang's battery cannot be charged due to reasons such as dried-up electrolyte in the battery, broken plates, or short-circuited plates. The most common and primary reason is plate sulfation, which obstructs the normal flow of electrons, leading to reduced battery capacity, inability to function properly, and gradual aging. If a battery is left unused for a long time or is chronically undercharged, plate sulfation can occur. For batteries that have been in use for more than 3 years, it is recommended to replace them with a new one. For batteries with shorter usage periods that have experienced mild sulfation due to short-term excessive discharge, a low-current, long-duration charging method can be used for recovery. However, the battery capacity can only be restored to about 80% of its rated capacity. There are several main reasons for the early failure of vehicle batteries: Deep discharge: When the vehicle is parked but the lighting or other electronic devices remain on, the battery continues to discharge. Prolonged discharge significantly reduces the battery's lifespan. Overcharging or engine overheating causing electrolyte evaporation: Since the electrolyte is composed of specialized sulfuric acid and distilled water in a specific ratio, engine overheating will accelerate the evaporation of distilled water, disrupting the balance between sulfuric acid and distilled water in the electrolyte and shortening the battery's lifespan. Loose alternator belt leading to insufficient charging: The vehicle's alternator supplies power to the electronic devices and charges the battery while the vehicle is in use (except during idle). If the alternator belt is too loose, it will result in insufficient charging of the battery, affecting its normal operation.

What is Gasoline Additive?

Gasoline additive, short for fuel additive, is designed to compensate for the inherent quality issues of fuel and the limitations in automotive mechanical manufacturing. It enables gasoline engines to overcome the cold shock effect and crevice effect, serving to remove carbon deposits from intake valves and fuel injectors. The composition and functions of gasoline additives can be categorized into: 1. Maintenance-type fuel additives: They envelop carbon deposit particles formed through oxidative condensation reactions at high temperatures, preventing them from growing larger; 2. Cleaning-type fuel additives: When carbon deposits accumulate on the surfaces of fuel injectors and intake valves, cleaning-type additives utilize surfactants to penetrate the pores of carbon deposits, disrupt their structure, segment and envelop the carbon particles, and dissolve them for expulsion through exhaust emissions.

What does it mean when the battery indicator light comes on after a car self-check?

It is normal for the battery indicator light to come on after a car self-check, as it is used to display the working status of the car battery. The light is usually red or yellow and will turn off after the vehicle starts. If the battery indicator light remains on after the car starts, it indicates an abnormal situation. The possible reasons for the light staying on are: 1. There is a fault in the charging system; 2. The battery voltage is slightly low; 3. The generator belt is broken; 4. There is a fault in the power supply circuit. The maintenance methods for a car battery include: 1. Avoid parking in an open parking lot for extended periods; 2. Avoid repeatedly starting the vehicle without interruption; 3. Regularly check accessories and connecting lines; 4. Do not use car electronics after the engine is turned off.

What is the Difference Between Electromagnetic and Moving-Coil Instruments?

Electromagnetic and moving-coil instruments differ in the following aspects: 1. Different structures: Electromagnetic instruments consist of fixed coils; moving-coil instruments are composed of permanent magnets, pole pieces, and a cylindrical iron core. 2. Different characteristics: Electromagnetic instruments feature simple structure, strong overload capacity, and the ability to operate on both AC and DC; moving-coil instruments offer high sensitivity, stable and reliable operation, low power consumption, and minimal influence from external magnetic fields. 3. Different principles: In electromagnetic instruments, the fixed coil carries the measured current, magnetizing both the fixed and movable iron pieces, which repel each other to generate a torque that drives the pointer, with the deflection angle proportional to the square of the current; in moving-coil instruments, the movable coil carries the measured current, experiences force in the air gap magnetic field of the permanent magnet, and generates a torque to drive the pointer, with the deflection angle proportional to the current.
