Lithium power battery characteristics.portable solar generator

　　(1) The operating voltage of the single battery is as high as 3.7V, which is a nickel -cadmium battery, three times that of nickel -metal hydride batteries, and nearly 2 times the lead -acid battery. This is also an important reason for lithium -power batteries to be higher than energy. Therefore, when the power battery pack that forms the same voltage, the number of series used in lithium -power batteries will be larger than that of lead -acid batteries and nickel -hydride batteries. If the number of single batteries in power batteries, the higher the consistency requirements of the single battery in the battery pack, the worse the life span. After the battery pack has problems in the actual use process There is a problem with a single battery and then causes a problem with the entire set of batteries. Therefore, it is not difficult to understand why 48V lead -acid batteries have higher feedback than 36V lead -acid batteries. From this perspective, lithium battery is more suitable for the use of power batteries. For example, the lithium battery of 36V only needs 10 monomers, while 36V lead -acid batteries need 18 monomer batteries, namely 3 12V battery packs, and each 12V lead -acid battery has six singles, namely six monomer batteries composition.

　　(2) Light weight, larger than energy, up to 150Wh/kg, is 2 times that of nickel -metal hydride batteries, and 4 times the lead -acid battery. Therefore, the weight is one -third to a quarter of lead -acid batteries with the same energy. From this perspective, there are fewer resources consumed by lithium batteries, and because the elements used in lithium manganate batteries are more reserves, relative to lead -acid and nickel -metal hydride batteries may further increase their prices, and the cost of lithium -power batteries is further reduced. The weight of the lithium battery for electric bicycles is 2.2-4 kg, the weight of the lead-acid battery is 12-20 kg, and the weight of the lithium battery is about one-quarter to one-third of the lead-acid battery, which is about 10 kilograms lighter than the lead-acid battery ( 36V, 10AH battery), the battery weight was reduced by 70%, and the total weight of the vehicle was at least 20%. In addition, the general lithium tram is a simple electric bicycle. Because the battery and the vehicle are light, the battery mileage of the same voltage and the same capacity is longer. The weighs of ordinary electric vehicles are more than 40 kg. Between 7 and 26 kg. Both ladies and the elderly can move easily, and the human ride is also very light, and both exercise and leisure.
