A battery control device and a battery capacity estimation method are provided. The battery control device includes a current detector and a processor. The current detector detects the battery. The processor is electrically connected to the current detector. The processor performs coulomb current integration to obtain the integrated value based on a current detection result of the battery detected by the current detector during a sampling period. The processor multiplies the integrated value by a battery coulomb beta coefficient to obtain a depth of discharge. The processor calculates a first relative state-of-charge of the battery according to the depth of discharge and determines remaining battery power information according to the first relative state-of-charge.

Battery control device for determining remaining battery power information and battery capacity estimation method

A portable electronic device with projection function including a host, a projection module, a signal line, a first adjusting leg and a second adjusting leg is provided. The host has a chamber at its side. The projection module is for outputting an image light beam. The projection module is connected to the host through the signal line. The first adjusting leg is pivoted to the projection module. The second adjusting leg is pivoted to the projection module, wherein the first adjusting leg and the second adjusting leg can be stored into the chamber with the projection module after pivoting.
