Abstract

The Nickel-metal hydride (NiMH) batteries, a mean of power supply for portable equipment, have less pollution to the environment. They need to be set the technical parameters of them for prolonging their service life. So that they should be converted between Fast-charge and Trickle-charge to prevent overcharging. The Fast-Charge management chip, Max712/713, is designed by MAXIM company. And it can meet the Charge needs of 1-16 series NiMH batteries and has programmable functions. The two NiMH batteries with a capacity of 1300mAh and a voltage of 1.2v are designed programmatically. The number of rechargeable batteries and the time of quick charging are controlled by the pin allocation. Within two hours, the battery charging test is used to record the changes of the voltage at the two ends of the battery pack, the programmable charger automatically changes the state during the charging process. Therefore, it can protect the battery from overcharging.
