How to extend the power supply time of uninterruptible power supply (UPS)

Aug , 03 2024

There are two ways to extend the duration of an uninterruptible power supply： 1. Increase battery capacity. According to the length of time required to increase the number of batteries, but this method will cause a relative increase in battery charging time, but also increase the number of corresponding maintenance equipment, increase product size, resulting in an increase in the overall cost of U...

Four operating modes of UPS

Aug , 23 2024

1、Normal operation mode The principle of the power supply system is that when the utility power is normal, the machine will convert the alternating current of the utility power to direct current, and then charge the battery for use when the power is interrupted; it is emphasized here that the power supply system will not only act when the power is out, such as when the voltage is too low or high, ...

Lithium battery life The reason for the slow charging speed

Dec , 13 2024

1. Electrical problems: Insufficient power of the charger is one of the common reasons for slow charging speed. If the output current of the charger used is small and cannot meet the maximum charging current requirements of the battery, the charging speed will be limited. For example, a lithium battery mobile phone that supports fast charging, the original charger output current is 3A, and the cha...

Causes and methods of lithium battery life decline

Dec , 13 2024

1. Battery aging: After multiple charge and discharge cycles, the chemical substances inside the lithium battery will gradually undergo irreversible changes. For example, the structure of the electrode material may be damaged when lithium ions are embedded and deembedded between the positive and negative electrodes. Taking the common lithium cobalt oxide cathode material as an example, with the in...

Advantages of lead-acid colloidal batteries

Mar , 28 2025

1. Long service life: The colloidal electrolyte can form a solid protective layer on the plate, reduce the bending and short circuit of the plate when used under heavy load, delay the softening and shedding of the plate, and make the battery life reach 1.5-2 times that of ordinary lead-acid batteries. 2. High safety: The electrolyte is solid, sealed, and never leaks. There is no acid mist gas prec...

How to choose the right lithium battery

Mar , 28 2025

1. Identify application scenarios The purpose of lithium batteries directly affects parameter selection: Portable devices (mobile phones, drones, cameras): give priority to high energy density (such as ternary lithium batteries) and lightweight. Electric vehicles/power tools: require high discharge rate (C-rate) and long cycle life (such as lithium iron phosphate batteries). Energy storage systems...

What Is UPS Input Power Factor and Why It Matters

Apr , 12 2025

Power factor (pf) is the difference between the actual energy consumed in an AC circuit and the apparent power. It will be calculated as a decimal or percentage between 0-1 pf and 0-100%, i.e. 0.9 pF=90%. Meaning of UPS power factor UPS input power factor UPS input power factor is the ratio of UPS input active power to input power. UPS is not only a part of the power supply, but also the load of t...
