What to Do When an Electric Vehicle Fails to Charge?

Does the Rear Differential Need Replacement?

Rear differential fluid needs to be replaced, with a typical replacement interval of 80,000 to 100,000 kilometers. Changing the differential fluid prevents excessive wear on the vehicle's differential gears, which could lead to differential damage. Differential fluid is the lubricant for the rear axle gear transmission mechanism, also known as gear oil. Its primary functions are lubrication and cooling. Due to variations in the positional relationship of gear axes and tooth profiles, there are significant differences in contact stress and relative sliding speed at the meshing surfaces of gears, necessitating the use of different gear oils. Failure to replace differential fluid increases friction between gears in the differential structure, raising vehicle fuel consumption and potentially damaging the differential, differential lock, and other components over time. The functions of differential fluid include forming an oil film on gear meshing surfaces to reduce friction and extend component lifespan, as well as dissipating heat generated by friction pairs through fluid circulation for cooling purposes. Its working principle involves maintaining high temperatures in the differential lubricant during high-speed driving—far exceeding engine oil temperatures—to ensure proper vehicle operation.

What is the function of electrolyte?

Electrolyte serves two main functions in a battery: facilitating electrochemical reactions and enabling electrical conductivity. Below are the relevant details: Electrochemical reaction function: In lead-acid batteries, the electrolyte enables electrochemical reactions. When the battery discharges, the electrode plates absorb sulfuric acid from the electrolyte and release electrical energy. Without electrolyte, the battery cannot discharge electrical energy. During charging, the electrode plates release the sulfuric acid absorbed during discharge, restoring them to their initial state. Conductive function: The electrolyte in lead-acid batteries provides electrical conductivity. The positive and negative electrode plates of the battery are insulated from each other, and without electrolyte, a current circuit cannot be formed. The electrolyte is prepared by adding sulfuric acid to non-conductive pure distilled water, which then becomes a conductive medium. Only with this medium can an external load be connected between the battery's positive and negative plates to form a complete current circuit. Current can then flow freely within the battery, enabling electrochemical reactions to occur at the electrode plates for charging or discharging.

What does car audio EQ mean?

Car audio EQ refers to the music equalizer. The following are relevant introductions about car audio: 1. Technical points: There are five aspects to pay attention to in car audio technology. One is the installation size and installation technology, another is the vibration isolation technology of the audio itself, another is the sound quality processing technology, another is the anti-interference technology, and the active noise reduction technology recently applied in the automotive field. 2. Selection of signal cables: They must have good anti-interference performance, reduce signal attenuation, ensure good contact, and prevent oxidation at the joints. Some top-tier signal cables often use special alloy materials, ring-type plugs, and gold-plated plug surfaces to prevent oxidation. 3. Principle of high power output: The so-called principle of high power output in an audio system is that the output power of the main unit or amplifier must be set appropriately. A higher output power indicates a broader audio linear range they can control, which also means they can drive speakers more effectively. Small power amplifiers not only easily distort the sound but can also cause the amplifier or speaker coils to burn out more frequently.
