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, ...

Effect of electrolyte density and discharge on lead-acid batteries

Nov , 29 2024

(1) Electrolyte density under different geographical and climatic strips. Whether the electrolyte density is high or low, it is necessary to make a specific analysis for the specific situation. Winter temperature is low, the viscosity of the electrolyte is large, it is not easy to penetrate the inside of the plate, the end voltage and capacity of the battery will decline, especially in the strong ...

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...

Why battery calibration?

Apr , 03 2025

Definition of Battery Calibration Battery calibration refers to the process of resetting and synchronizing the battery's power management system with the device's software to accurately gauge the battery's charge level and capacity. This procedure involves fully charging the battery, allowing it to drain completely, and then recharging it to recalibrate the device's battery indicator to provide ac...

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...

How to maintain the consistency of lithium batteries

Apr , 19 2025

1. Balance control of the Battery Management System (BMS) Passive equalization: Through resistor discharge, the energy of high-charge cells is dissipated in the form of heat, making the voltages of each cell tend to be consistent. It is suitable for cost-sensitive scenarios, but the efficiency is relatively low. Active balancing: It transfers the energy of high-charge cells to low-charge cells thr...
