A battery charging system controls and modifies the output voltage of the charging rectifier in response to differing temperature ranges of the battery. At a low range of temperatures starting at a low temperature (e.g. within a range of 0 to 25°C to about 53°C) the rectifier voltage decreases as the temperature increases to prevent charging current from rising as the battery temperature increases...
This paper presents the results of a prototype charger development, coupling a dual-level constant potential charger with a microprocessor controller. The controller implements a charging algorithm which exploits the inherent Ampere-Hour Rule of lead-acid batteries to prevent overcharge while guaranteeing rapid recharge, independent of the battery technology, battery age, battery capacity, discharge...
