What are the differences between power batteries and capacity batteries?
Lithium battery is believed to be familiar with everyone. Our mobile phones, laptops, and charging treasures, including the shadow of lithium batteries on new energy electric vehicles that are being promoted! Life and health have always been human concern The key topic, in the early nineteenth century, in order to provide power to the pacemaker in the early nineteenth century, it also contributed to the development of lithium batteries. The battery provides power sources, which is undoubtedly equivalent to the importance of the heart to people. The public who did not understand the lithium battery believed that the lithium batteries were similar, but the difference between size and capacity! But in fact, there is really a big difference. Lithium batteries are divided into many types from raw materials. If you want to know, you can follow me. Search for the type of lithium battery, what exactly is power battery? What is a capacity battery?
Capacity battery
mainly provides a longer battery life for the product, with energy density as the main research and development Lithium battery in the direction. For example, the consumer electronics equipment, mobile phones, notebooks, charging treasures, etc. we use our daily use. You can find that as technology improves his battery life is gradually increasing and the volume is constantly smaller.
Difference
1. Different volume, most of the capacity batteries are used on consumer products, generally small volume, such as mobile phones. Power batteries are generally large, such as drone batteries.
The difference between discharge, large internal resistance battery resistance, and small discharge current during the unit time. Because the power of the power battery is high, the internal resistance is small, and the discharge current is relatively large during the unit time. In the battery industry, the power battery uses a single -stack bipolar ear in the unit, or the current of the entire battery pack is increased by the multi -body parallel. The direct role is to increase the capacity of the power lithium battery pack. The capacity of the battery group connected in this way is often large. Because the internal resistance is small, the current discharge time is long.
3. Safety differences
1. Safe, capacity, capacityThe battery is generally used alone, and the power battery is generally used in groups, so that the safety design of the power battery is more complicated. In terms of simply heat dissipation, the capacity battery can completely heat the heat and the power battery of the group. Consider the heat dissipation channel when designing heat dissipation.
2. Product safety, the capacity battery has little protection of the product. Most of them are the safety design of the product itself, so the capacity battery itself only relies on the material and design of the battery on the basis of higher energy density. All kinds of situations that endanger safety. The main body of the product of the power battery is generally high, and the design is more redundant. It uses thicker diaphragm, foil and shell to ensure the safety of the main body of the product. Therefore Of course, more external protection circuits, heat dissipation layouts, etc., of course, they also face worse conditions (higher external voltage, larger current, more complex external environment).
Four and consistency, the capacity battery does not require long -term reliability, because most of them are used on consumer electronics alone, so there is no big requirements for consistency, but because of the limited product space, consumer categories Capacity Lithium -ion batteries have high requirements for strict size, capacity, energy density, etc. High -end consumer batteries use the most advanced technology and materials, and power batteries require advanced process control, consistency control and quality management.
Lithium batteries are divided into power batteries and capacity batteries, do you know the difference between them?
Intelligent battery of power battery planting protection
V. Circular life, capacity battery is generally consumer consumption Electronic products, because the update iteration is too fast and the discharge environment is relatively mild, so it will not focus on the cycle life when designing. It is like a mobile phone found that the battery is not durable after a year. Gradually improve.而动力电池的使用环境恶略，产品的使用周期很长，所以在设计时必须要考虑循环寿命，虽然实际使用时感觉动力电池的循环寿命很短，大多数都在300-500次，然而手机It has been thousands of times in a few years every day. Why is the cycle life of the capacity battery comparable to power batteries? In fact, this contrast is incorrect. In the same environment, the cycle life of the power battery is far greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than greater than. If a capacity battery, if a capacity battery is used to replace the power battery, in other unchanged cases, it may only be used dozens of times.
