Battery charger options (part-3)

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 charger solution. Charge Dividers Our charge divider option adds series diodes to the output of our charger to isolate multiple banks of batteries. The battery banks, in effect, do not see each other, allowing each bank to be charged complet...

High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-1)

Jun , 13 2022

Battery charging is a complex electrochemical process, in which the discharged electric energy is replenished from the electric power grid. This is accomplished using a battery charger, which is an electrical/electronic device that converts the incoming AC line voltage into a regulated DC voltage to meet the charging needs of the respective battery. In a series of articles we are going to explain ...

What are some key practices for a Fast or Opportunity charge operation?

Jun , 20 2022

What are the operational implications of charging at a higher rate? Initial Cost: Initial charger investments may cost up to 5 times more than a conventional charger operation, especially if the charging system utilizes a dedicated charger for every battery. Infrastructure Change: Once committed to the Fast or Opportunity charge process, it can be very difficult to transition back to Conventional ...

What types of monitoring and recording devices are suited for high rate charging?

Jun , 20 2022

The higher the charging rate, the more critical it is to monitor the charging process to prevent permanent capacity loss. In efforts to preserve battery life, Fast and Opportunity charging incorporates a method of monitoring battery electrolyte temperature and/or internal resistance and adjusting charging current as necessary. Although these monitoring devices can have a very positive impact on ba...

Efficiency of DC power system

Jun , 27 2022

In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...

Power Factor and Harmonic Analysis in Single phase AC to DC converter

Aug , 15 2022

Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part ofmost of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC toDC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is used ...
