The Design Of Battery Charging Equipment
Abstract:With the rapid development of portable electronic products, the variety of batteries increase fast, so does the improvement of quality. The output of the rechargeable batteries is enlarged also. Moreover, the requirement for the recharger is tend to be high efficiency, small size, and low cost, light weight, safe and practical. In this paper, the current design principle of chargers pared. Using the rapid-charging management chip MAX712 produced by MAXIM, the battery refresh circuit has pleted. And the low-cost and low-power switching power controller--NCP1215 made by Ansemi is adopted to design the power circuit. The input voltage of the device is AC 200-240V, the DC voltage output is , and the DC power output is 7W. In addition, the device can recharge the #5 nickel-hydrogen/nickel-cadmium batteries quickly, and with controlling the changeable power in the process of charging, the battery can be protected from the over-charging.
