12V lithium ion battery parameters

The 12V lithium battery is a relatively common lithium battery pack, which has a wide range of uses and is suitable for use in a variety of devices. According to conventional needs, the capacity of the 12V battery ranges from 2000mAh-200Ah, and the battery capacity standards are matched according to the actual use. Small 12V lithium ion battery is usually used in the production of 18650 battery combination, 12V lithium ion battery parameters: combination method: ICR18500-3S2P / combination of cell model and cell arrangement method nominal voltage: 11.1V according to the standard combination of cells The standard voltage is 11.1V for the 3.7V platform and 10.8V for the 3.6V platform, but both of these standards are 12V lithium-ion batteries. Discharge voltage: 8.25V-12.6V Generally speaking. 8.25V is the maximum discharge limit of 3 strings of ternary lithium batteries, and the protection board usually uses this standard to set the protection voltage of the battery pack. The conventional discharge current is: 0-2A, large capacity is 3-4A / The discharge current of the lithium battery depends on the setting of the protection board BMS and the performance of the battery itself. Nominal capacity: In MahA unit, there are multiple size standards. Continuous charging current: 0.2C Maximum continuous discharge current: 1C Working temperature: Charging: 0~45℃ Discharging: -20~60℃ Conventional non-low high temperature special lithium ion The batteries are basically capable of discharging in this temperature range. Product size: xxxxx Finished internal resistance: ≤280Ω The lower the internal resistance of the finished product, the better. Use a higher standard and high-quality battery to protect the board: IC-S8254AAJ+MOS-AO4409 Lead model: JST-VHR-2P positive plug UL1007/24# line, line length 100mm overcharge protection voltage/each string 4.35±0.025V overdischarge protection voltage 2.75±0.08V overcurrent value: 5~8A battery capacity: there is no standard capacity, it is based on the electrical appliances, or The specific requirements of the equipment are determined. The general capacity is: 2200ma/h, 5AH, 10Ah. Some electric vehicles have a capacity of 20AH or 50AH. The more batteries are connected in parallel, the greater the capacity. According to the physics formula: in the parallel circuit: Itotalu003dI1+I2+I3[1] Volume: The volume of a 12V lithium-ion battery is determined according to the battery capacity, and there is no uniform specification. The larger the battery capacity, the larger the volume and weight: Many devices now require large-capacity and lighter lithium-ion batteries, such as electric vehicles, which used to use lead-acid batteries. Now many electric vehicles have become lithium-ion batteries because of lithium-ion. The battery has large capacity, light weight and small size. Charge and discharge current: The charge and discharge current of a lithium-ion battery is determined according to the power of the device. The electric power formula is: Pu003dUI[1]. On the basis of constant voltage, the greater the power of the device, the greater the current to be output.
