  • What is a high-rate battery?

    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,…

  • Why does lithium battery pack need aging test?

    Lithium battery pack aging test is an indispensable procedure in the production process of lithium batteries. It is to better evaluate battery life and performance attenuation, so as to ensure the stability and reliability of factory batteries. What is battery aging test ? The battery aging test is a test that simulates the actual use of the battery, performs charge and discharge cycles on the battery, and records the performance of the battery. This kind of test is generally divided into normal temperature aging and high temperature aging. As the name implies, the battery is placed under normal temperature and high temperature conditions for charge and discharge cycle testing. In the battery aging test, the general test indicators involve the internal resistance, voltage and capacity of the battery, and these data are of great significance for the evaluation of the battery.

  • Three types of UPS batteries, how much do you know?

    Uninterruptible power supplies (UPS) use three primary types of batteries: Nickel-Cadmium, Lead-Acid, and Lithium-Ion, each with its own set of advantages and disadvantages. Let’s start with key characteristics of each battery technology. Nickel-Cadmium (Ni-Cd) batteries: Ni-Cd batteries have a long lifespan(about 20 years design life) and can withstand high temperatures without significant performance degradation, making them a good choice for applications that require high reliability and durability in extreme climate conditions. They also have inherent resistance to overcharging. This means they are less prone to damage caused by overcharging, reducing the risk of performance issues. However, Ni-Cd batteries are relatively expensive. What’s more, the disposal and recycling processes at the end of their service life are extremely costly and have environmental impacts due to the toxicity of nickel and cadmium. Lead-Acid batteries: Lead-Acid batteries have two different types: Valve Regulated Lead Acid(VRLA)and Flooded Lead Acid ( FLA)。 The electrolyte inside VRLA…
