Analyzing the difference between the power lithium battery and lithium battery capacity

Source: 2020 - 03 - 25 14:07 hits: time is the difference between power lithium battery and lithium battery capacity? Believe everybody's familiar with lithium battery, our mobile phones, laptops, charging treasure, including is the promotion of new energy electric vehicles can see the figure of a lithium-ion battery! Life and health is an important subject of human concern. In the early 19th century, in order to give a pacemaker, it also has made a contribution to the development of lithium battery. Batteries provide the power. Without understanding the public think lithium battery is the same as the lithium battery, just different in size and capacity! But the practice is really a big difference, lithium battery from the raw material is divided into a lot of kinds, if want to know can pay attention to me, looking for the varieties of lithium-ion batteries, power battery is what? What is the capacity of the battery? Battery capacity mainly provide products with long life, energy density as the main research direction of lithium-ion batteries. For example, in our daily use of consumer electronic equipment, mobile phones, notebook computers, power pack, etc. , you can see, with the progress of his skills and his ability to increase gradually, his size decreases. Battery capacity - Battery power battery main supply high discharge rate, continuous and stable products, voltage and current to the battery safety as the basis of the rope feet, positive product reliability as the main development direction of lithium-ion batteries. If we plant protection uavs batteries, new energy electric vehicle batteries, with the progress of technology, increasing its stability and security. Power battery unmanned aerial vehicle (uav) battery size differences. Capacity of the battery is mainly used in consumer products, usually small, such as mobile phone. Power battery, such as used for unmanned aerial vehicle batteries, are often large. Discharge difference is big, great capacity of battery internal resistance, small discharge current per unit time. Power battery as a result of the drive power is great, so small internal resistance, unit time discharge current is larger. In the battery industry, driven by double fold bipolar ear cells, or in many body as a unit in parallel to increase the whole current of battery pack. Battery capacity under the influence of output current, parallel direct effect is to increase the capacity of the power lithium battery pack. The capacity of the battery connection in this way the capacity of the battery pack tend to be larger, because the internal resistance larger discharge current is small, so the continuous discharge time is long. Three, safety difference is 1. Its own security, capacity batteries are often used alone, and power battery is commonly used in groups, the safety planning of power battery is more complex, for the simple heat dissipation, integrity can be achieved by thermal capacity battery, battery and power group, planning considering the cooling cooling channel. 2. Product safety. Capacity of the battery for the product protection is very small, most of the product is safety planning. Subject generally higher value of power battery products, planning of redundant, with thick film, aluminum foil and the shell, in order to ensure the safety of the product, so the energy density is not battery capacity, but more external power battery protection circuit, heat dissipation planning, and so on, of course, is faced with more harsh conditions, External high voltage, high current, more complex external environment) 。 Fourth, incompatible, the reliability of the batteries don't need long time, because most of them are used separately in the consumer electronics products, so there is no big demands incompatible, but because of the limited product space, so consumer capacity lithium ion battery is serious, the size of the capacity, energy density and other requirements. High-end consumption battery using the most advanced technologies and materials, and power battery requires more advanced process control, compliance control and quality management. Power battery - Eppo intelligence, cycle life, capacity of the battery cell 5 general consumer electronics products, and iterative update too fast, and discharge environment is relatively mild, so the plan will not pay attention to cycle life, like a cell phone use after a year, found that the battery is not durable, but as the skill, this phenomenon is gradually improving. And the use of power battery environment is a bit poor, the use of the product cycle is very long, so need to consider when planning cycle to grow old, of course, want to consider when using power battery life cycle
