What are the electric vehicle batteries?

The maintenance-free lead-acid battery is actually an upgraded version of the ordinary lead-acid battery. It has a fully enclosed shell structure and does not need to be maintained during use. It saves the trouble of frequently refilling ordinary batteries with distilled water. It is a more worry-free version. The product. Analysis of the advantages and disadvantages of the three lead-acid batteries. Maintenance-free batteries are not only maintenance-free, but they also have better shock resistance than ordinary batteries, but the price is relatively more expensive. In addition, its overall life span is not significantly better than that of ordinary lead-acid batteries, so the overall cost of use will be slightly higher than that of ordinary lead-acid batteries. In addition, there is a legend in the market that the low-temperature discharge capacity of maintenance-free lead-acid batteries is not as strong as that of ordinary lead-acid batteries, but it is currently impossible to judge whether it is true or not. ●Wound lead-acid battery. Many people have not heard of the wound lead-acid battery. The biggest difference between it and the ordinary lead-acid battery is that the structure is different. The inside of the wound type has a spiral structure, while the ordinary battery is a flat plate. Plate structure. It has the characteristics of large starting power, long service life, fast charging and small self-discharge, strong anti-vibration and impact. It can work normally in the temperature range of minus 55 degrees Celsius to 75 degrees Celsius. In addition, its internal structure is all solid, so the vibration resistance is very strong, and it can withstand four times stronger vibration than ordinary batteries. Which one is better to analyze the advantages and disadvantages of the three lead-acid batteries. The internal structure of the wound lead-acid battery is spiral, and the electrolyte is all absorbed by the battery separator, there is no flowing liquid, so it can be used normally even in an inverted state. In addition, the winding battery can output three times stronger current than ordinary batteries, which is very suitable for cold start in winter.
