12V lithium-ion battery precautions, what is the use of 12V lithium ion batteries? The 12V lithium-ion battery is serially connected in series with 3 or 4 lithium ion batteries. The composite battery pack, the capacity of the battery is determined according to the capacity of a single cell, or the capacity of the battery parallel, is a safe and environmentally friendly new battery. The 12V lithium-ion battery uses the most widely used battery type, which plays a very important role in our production and life.
Today talks about 12V lithium-ion battery precautions and what it is. 12V Lithium Ion Battery Precautions 1, different 12V lithium-ion battery brands, different batteries, battery models are also different, the charger is naturally different, and cannot be common. If you often mix the charger, the charging voltage and current do not match, it will cause the battery to be drumped.
2, the summer charger can stop charging after turning green light, and the winter charge can be floated for 1-2 hours. More than 12 hours, or even longer, it is easy to charge the battery. 3, charging at high temperatures, the charging voltage is relatively high, the battery is extremely easy to overcharge, resulting in the growth of the battery inadequilly during charging, which seriously affects the battery life.
The research data shows that when the battery is at 45 ° C, the life is reduced by 40%. 4, 12V Lithium Ion Battery In use, the battery itself will heat, if used immediately after use, the battery is in a high temperature environment for a long time, and it is easy to charge. 12V lithium-ion battery use 12V lithium-ion battery protective plate is a battery protection circuit board, generally used in large capacity 12V lithium-ion batteries, with overcharge, overlapping, overcurrent, short circuit, battery balancing function, some batteries It may be necessary to communicate port and data input and output options and other display functions to achieve application requirements.
12V lithium-ion batteries are applied to electric vehicles, inverters, mobile DVDs, UPS, GPS, medical settings, etc. The application sector of the positive material is clearly differentiated. At present, lithium cobaltate is still the main force of the positive material material in the small lithium-cell field.
It is important for the traditional 3C field. The three-dimensional materials and lithium manganate are important in small lithium electrical applications, in Japan and South Korea as a The technique of power lithium batteries is relatively mature, important for electric tools, electric bicycles and electric vehicles, etc .; 12V lithium iron phosphate ion batteries in domestic dynamic lithium battery areas, and is the direction of future energy storage batteries, important for Base station and data center energy storage, home energy storage, scenery, etc.
12V Lithium Ion Battery Specification Parameter ● Voltage: 12V ● Battery Capacity: The capacity is not standard, it is determined according to the specific requirements of the appliance, or the device, and the general capacity is: 2200mA / h, 5ah, 10ah, some electric vehicles The capacity can reach 20ah, or 50ah. The more battery is connected, the greater the capacity. ● Volume: 12V lithium ion battery volume, to be determined according to the capacity of the battery, no uniform specifications.
The larger the battery capacity, the greater the volume. ● Weight: Now there is a lot of equipment to be large, lightweight lithium-ion batteries, such as electric cars, before using lead-acid batteries, now many electric vehicles become lithium-ion batteries, because lithium-ion battery capacity is large, lightweight, light, small volume. ● Charge and discharge current: The charge and discharge current of the lithium ion battery is determined according to the power of the device.
On the basis of constant voltage, the larger the power of the device, the greater the current to output. The 12V lithium-ion battery has an overcurrent protection. When the usage current of the electric device exceeds the maximum output current of this product, the overcurrent protection circuit action does not seem to work normally.
12V lithium-ion batteries are equipped with dedicated chargers in the factory to prevent life and characteristics of lithium-ion batteries.
