Method of charging batteries

摘要

In a method of charging batteries, a microcontroller and a series divider resistor are used to control the level of a charge current source supplied from a power supply, so that a plurality of serially connected batteries in a battery pack could be best charged. The microcontroller detects a voltage value of the battery pack via the series divider resistor. When all the batteries in the battery pack have been charged in a first charging cycle, the microcontroller controls the power supply to lower the output charge current and to charge the batteries in a second charging cycle, until the charge has been cycled a preset number of times. As a result, all the serially connected batteries in the battery pack are best charged.
