In the process of using of batteries, have you found that when some batteries are used under high load, the battery life is much reduced than the theoretical value? If you happen to be using a lead-acid battery, then part of the reason for this is the so-called Proctor’s law. Next, let’s learn what Puckett’s law is and what its impact is on batteries? What is Puckett’s law? Peukert’s law was proposed by German scientist Wilhelm Peukert in 1897. It states that the capacity of rechargeable lead-acid batteries changes at different discharge rates. As the discharge rate increases, the available capacity of the battery will decrease. According to the actual situation of the battery, it can be expressed by the following formula: t = H(C/IH) k , where H is the rated discharge time (h) , C is the rated capacity at the discharge rate (Ah), and I is the…

We often see the words of “with intelligent BMS” in lithium iron phosphate battery packs description. What is the “BMS”? What role does it play in the lithium iron phosphate battery pack? Next, let us discuss the BMS of the lithium iron phosphate battery pack. What is BMS? BMS is a set of electronics that monitors and manages the performance of all the batteries. The battery management system (BMS) of a lithium iron phosphate battery pack typically includes functions such as calculating the remaining battery power, monitoring battery temperature, and detecting battery safety and health status. It plays a crucial role in preventing or avoiding abnormal conditions such as over-charge, over-discharge, over-temperature, overcurrent, and short circuit. Due to its integral role in ensuring the safe and efficient operation of the battery pack, the BMS is often referred to as the “brain” of the battery pack. What are the main functions…

In modern society, the reliability of electricity supply is vital to many industries and households. When power interruptions or fluctuations occur, equipment may be damaged, data may be lost, or the production process may be interrupted. To solve these problems, uninterruptible power supply (UPS) systems are introduced, and UPS battery is an important part of the system. What is the UPS battery? The UPS battery is one of the core components of the UPS system. They are rechargeable batteries, typically using technologies such as lithium-ion, nickel-cadmium, or lead-acid. UPS battery can store energy by converting electrical energy into chemical energy and release the stored energy when power is interrupted to provide continuous power supply. The capacity of the UPS battery determines the backup power time that the UPS system can provide. A larger-capacity UPS battery can support the operation of the equipment for a long time, while a smaller-capacity UPS…

In the battery industry , we can often hear professional terms such as battery cell , battery module, and battery pack. Some customers tend to confuse and other customers think that these three are the same concept. In order to make everyone better differences, let me share with you the relation between these three! In fact, battery cell, battery module and battery pack are different stages of battery application. The structure of a lithium battery generally is battery cell -module- battery pack. The battery cell is the basic unit of the battery system. The process of assembling the battery cells into a group is called “PACK”. It can be a single battery or a battery modules of Series and parallel battery , etc. In order to make everyone a deeper understanding, let’s take our PLB’s battery as an example to introduce the battery cell, battery module and battery pack in…

Cylindrical lifepo4 batteries and prismatic lifepo4 batteries are the most popular lithium iron phosphate batteries currently on the market. Although they work on the same principle, the difference in shape affects the performance of the battery. Next, let’s know about what are the differences between lithium iron phosphate batteries and prismatic lithium iron phosphate batteries? What are cylindrical and prismatic lifepo4 batteries? Cylindrical lithium iron phosphate battery is a battery with a cylindrical appearance. The battery structure mainly includes: cylindrical steel shell, steel cap, positive electrode, negative electrode, separator, electrolyte, gasket, explosion-proof safety valve , etc. The logo of a cylindrical lithium iron phosphate battery generally consists of 3 letters and 5 numbers. The first two letters represent the battery material, the third letter represents the shape of the battery, and the 5 numbers represent the diameter and height of the battery respectively. For example, “IF” in “IFR 26650 ”…

We often hear about high-rate batteries, so what exactly are high-rate batteries? Generally speaking, a battery that can support multiple times of its own standard discharge current is called a rate battery. The discharge rate is usually represented by the letter “C”, which is the ratio of the lithium battery’s discharge current to the battery’s nominal capacity. 1C is 1 C-rating, 2C is 2C-rating, and a battery that reaches 10C and above is called a high-rate battery. Taking the PLB IFR26650 2500mAh high-rate battery cell as an example, 1C means that the 2500mAh battery cell is discharged with a current of 2500mA and can be discharged for 1 hour. 2C means that the 2500mAh battery cell is discharged with a current of 2500mA×2=5000mAh and can be discharged for 0.5 hours. Because the battery core supports a maximum current discharge of 50C, the 50C discharge current of the battery is: 2500mA×50=125000mA,…
