The type and judgment method of ordinary electric bicycle battery

The types and judgment methods of ordinary electric bicycle batteries Before explaining the types of batteries commonly used in electric bicycles, first make it clear that this is the most commonly used lead-acid battery on the market, rather than the increasingly popular lithium-ion battery. Then explain two important parameters: voltage and capacity. Because they are collectors of lead-acid battery ID cards. Each battery in a lead-acid battery has a voltage of 2V. The most common battery combination for electric bicycles is three or four batteries in series, three at 36V and four at 48V. There are also 16V single-cell batteries composed of 8 batteries. The capacity of a lead-acid battery is determined by the voltage. Take a 12V lead-acid battery as an example, the minimum working voltage is 10.5v, and the maximum working voltage is 13.5v. The discharge from the highest working voltage to the lowest working voltage is 100% discharge. We combine battery voltage and capacity: public capacity: 10Ah, 12Ah; personal also has 14Ah, 17Ah, 20Ah. Commonly used 48V capacities are: 10Ah, 12Ah, 14Ah, 17Ah, 120Ah; the others are 15Ah, 16Ah, 18Ah, 22Ah and 24Ah. Some consumers may not know the specific model after purchase. At this time, by comparing the output voltage and output current of the charger, it can be identified from the charger: Generally speaking, the label of a 36V battery is: output voltage: 36V42V, DC×A. The corresponding relationship between battery output current and capacity is: 10Ah is 1.5a, and 12Ah is 1.6a. The label of the 48V battery is: Output voltage: 48V59V, DC × ×A. The corresponding relationship between battery output current and capacity is: 1.7a (10Ah), 1.8a (12Ah), 2.0a (14Ah), 2.3a (17Ah), 2.5a (20Ah). In addition to the labeling method of the charger, it can also be calculated by the battery itself. As mentioned earlier, the current average of 12v lead-acid batteries (6 cells) and 16v battery cells (8) shows that the single battery is again due to the series combination of lead-acid batteries, so it can be the product's single battery voltage and battery Voltage, battery capacity and single battery capacity are equal. For example, after opening the battery box, you will find three batteries. If these three batteries are 16V, the battery pack voltage is 16V×3u003d48V. If the three batteries are 12V, then the battery pack voltage is 12V multiplied by 3u003d36V. When the battery box is opened, what about the 4 batteries? In this case, if the four batteries are 16V, then the battery voltage is 16V times 4 equal to 64V; if the three batteries are 12V, then the battery pack voltage It is 12V multiplied by 4u003d48V. It can be seen that the same 48V battery pack can be 3 batteries in series or 4 batteries in series. The capacity is easier to distinguish. For example, the battery body marked as 6dzm-10 indicates that the battery/battery pack is 10ah, and the battery body marked as 6dzm-12 indicates that the battery/battery pack is 12ah. Of course, the virtual battery capacity is beyond the scope of this article. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
