Powering Alarms and Security Systems with backup batteries

Aug , 27 2021

Security and Alarm Systems are available in a wider variety of brands and capabilities than ever before and batteries for these systems also becomes important as well. The 12 volt 7/7.2/9 Ah battery is the most common battery used for alarm systems in the security industry. The requirements for choosing backup battery for alarm security systems are given below: Reliable: In alarms systems, the qua...

How to select the right battery backup for telecom sector?

Aug , 27 2021

Power outages are one of telecom companies’ worst nightmares, as they lead to loss of revenue, customers, image, and so on. In response, internet and telephone providers have expressed a keen interest in having a power backup system. There is a wide choice for telecom companies regarding which backup system they want such as diesel and natural gas generators, fuel cells and batteries. Ty...

Lithium battery cycle data analysis with constant voltage charging current and capacity decay curve

Oct , 29 2021

Generally, cycle life testing will generate a lot of data, which can obtain a lot of information. What analysis and processing can we do with these cycle data? The following summarizes some of the data processing, continuation from last week’s article. 1. Constant voltage charging current and time Lithium-ion batteries are usually discharged at different currents during use, and often cannot under...

What are the recharge cycles phases of a Lead acid battery?

Nov , 27 2021

The fastest generally accepted way to charge a conventional (lead‐acid or NiCd) battery is with a constant voltage, a current limited battery charger that is capable of both “boost” and “float” output voltages. “Boost” charging applies a higher than normal voltage to the battery early in the charge cycle to charge the battery as quickly as possible. Later, once the battery is charged, charging vol...

What is the right duration of Phase 2 of a charging cycle?

Nov , 27 2021

The duration of Phase 1 is determined by the battery’s depth of discharge, the ratio of charger ampacity to battery capacity, and whether there are parasitic DC loads connected to the system. Although the duration of Phase 1 does vary, we are not concerned with this variation since, once the battery capacity, charger output, and DC loads are installed, we have no means to change the duration of Ph...

What is Dynamic Boost and how does it works?

Dec , 03 2021

As with the current‐controlled automatic boost system, Dynamic Boost includes no pre‐programmed boost timer. Unlike the current‐controlled automatic boost system, however, Dynamic Boost automatically adjusts boost duration to take into account differing parasitic DC loads and other variables discussed above. The principle behind Dynamic Boost is simple and straightforward. Refer back to Figure 1. ...

How a new intermittent charging algorithm addresses premature SLI battery failure?

Dec , 06 2021

A new charging algorithm addresses the problems of short genset battery life and sudden battery failure discussed above, while meeting the regulatory needs to deliver non-stop DC power to critical applications. The principle is simple and straightforward. Emulate the beneficial intermittent vehicle charging regime for which SLI batteries were originally designed, but continue charger operation to ...

Battery charging tutorial-Part 1

Apr , 18 2022

Current battery charging technology relies on microprocessors (computer chips) to recharge; using 3 stages (or 2 or 4 stages) regulated charging. These are the "smart chargers", and quality units generally are not found in discount stores. The three stages or steps in lead/acid battery charging are bulk, absorption, and float. Qualification or equalization is sometimes considered another stage. A ...

Battery charging tutorial-Part 2

Apr , 18 2022

Equalization Equalization is essentially a controlled over charge. Some charger manufacturers call the peak voltage the charger attains at the end of the BULK mode (absorption voltage) an equalization voltage, but technically it's not. Higher capacity wet (flooded) batteries sometimes benefit from this procedure , particularly the physically tall batteries. The electrolyte in a wet battery can str...

DC-DC Converters-A suitable alternative to battery chargers

May , 09 2022

What if you had all the power you wanted or needed at 125 Vdc, but your site manager suddenly handed you a requirement for 24 Vdc to run some communication gear? You might tell him to buy a 24 V battery and a 24 V battery charger. But, these elements come with costs: initial, maintenance, and probable future battery replacement. There is another way: for approximately the same cost as the battery ...

Battery charger options (part-1)

May , 16 2022

In this series of articles we will discuss the options you can have in your battery charger. You can check out these options for choosing your desired battery charging solution. Special Ground Bus This is an appropriately sized ground bus bar mounted inside the battery charger to allow customers to tie ground connections inside the charger to the external system ground. The ground bus bar allows f...
