An improved growth-jump algorithm for determining the full charge of Ni-MH batteries
The charging process of Ni-MH batteries is an important part of their life cycle,and the saturation degree of charging has a significant impact on their usage life.The terminal voltage,temperature,and other parameters displayed during the charging process reflected the charging state of the battery.However,most of the cheap battery chargers on the market use a constant voltage and limiting current charging method,with significant fluctuations in voltage and current,and will continue to charge without artificial power outage,this will greatly shorten the service life of Ni-MH batteries,while the design of dedicated analog integrated IC charging chips is complex and has low maintenance.Now we are designing an improved growth-jump algorithm that can run on a small microcontroller under constant current,which can determine full charge after the battery is fully charged or slightly overcharged,achieving the goal of healthy charging and increasing battery service life.
