Customer ServiceIn general, battery chargers take standard AC power and convert it into DC power, which is then stored in the battery for use. Unlike traditional motive chargers, like ferroresonant, silicon controlled rectifier (SCR) and certain hybrid varieties, high-frequency chargers are simply more efficient.
High-frequency battery chargers have a higher power factor than traditional chargers. The power factor, which measures efficiency, ranges between 0 and 1, with 1 being the most efficient. To determine the rating, you compare the power the charger draws to the power the charger uses during charging. Are HF chargers worth the extra cost? YES
More and more researchers are exploring fast charging strategies for LIBs to reduce charging time, increase battery longevity, and improve overall performance, driven by the growing popularity of EVs. Nevertheless, fast charging poses challenges such as energy wastage, temperature rise, and reduced battery lifespan.
High charging rates can generate significant heat, potentially causing the battery temperature to rise rapidly, which in turn may affect its performance and lifespan . Batteries have higher charging efficiency at appropriate temperatures, while their charging efficiency decreases at temperatures that are too high or too low.
When establishing design standards based on charging time, it is crucial to consider the safety and reliability of batteries. Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery.
Researchers [38, 69, 70] have suggested using pulse current charging techniques to improve charging speed and prolong battery durability. Pulse charging strategy is primarily appropriate for batteries that exhibit sensitivity to polarization phenomena during the charging process and require optimization of charging efficiency and battery longevity.
