Pulse-Charging Techniques for Advanced Charging of Batteries

Abstract

Batteries are remarkable devices. Nowadays, they power devices everywhere, from small children toys to IoT devices, cellphones and automobiles, especially rechargeable ones. The need to have healthy batteries ready to be reused in a very short time is essential. Unfortunately, charging a battery is a trivial task that can lead to battery degradation and wear, even thermal escape and fire. The faster the charging process, the more the problems that arise in the charging battery. In this work, several charging algorithms and noteworthy, although mostly unknown, methods are presented and commented. For example, a common algorithm that produces good charging results is the Constant Current/Constant Voltage, abbreviated CC/CV, that is used in most battery chargers. Yet, the pulse charging algorithm, as presented, exhibits remarkable results compared to the common CC/CV algorithm. The pulse charging methods, as evaluated, keep the batteries healthy, achieving better charging results and lower charging time.
