Abstract: With increasing demand of electric driving power applications, the design of large batteries charger integrated with a well appropriate power supply is essential. However, normally commercial products are not suitable for such a requirement due to large size, complex system, high cost, etc. Therefore, this study proposes a rapid large batteries charging system based on optimal multi-stage mechanism and integrated with a simple high switching power supply and real-time charging curves tracking. It can provide a large constant charging current before reaching an overcharge point. The charging status can be displayed on LCD dynamically. The high-frequency switching converter using the PWM controlling scheme for the charger can provide a stable DC 60 V up to 15 A. The experimental results confirm that the proposed charging system is superior in term of simple structure, high efficiency, and robustness.
