Abstract
A battery detection system and related method are provided. The battery detection system according to the invention is coupled to a battery for detecting the type and remaining power of the battery, and includes a processor coupled to an A/D converter and an I/O control; a circuit, comprising a switch and a load, wherein the I/O control is used to control the switch for enabling or disabling the load. When the load is enabled, the A/D converter obtains a first voltage; when the load is disabled, the A/D converter obtains a second voltage. By calculating the first and second voltages, the processor obtains the type and remaining power of the battery.
