High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-2)

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 ...

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...

Explore and analyze the thermal power of Li- ion cells and battery packs (part-1)

Jul , 04 2022

Temperature is very important for lithium- ion batteries. Low temperature will reduce the electrical performance of lithium- ion batteries (capacity, rate performance), but it can improve the storage life of lithium- ion batteries. High temperature can improve electrical performance (capacity, rate performance), but It will reduce the stability of the electrode/electrolyte interface and cause a ra...
