Battery residual quantity display method and electronic equipment
First Claim
1. A microcomputer having a communication function used for a battery pack configured to be detachably loaded at an equipment body, the microcomputer being configured to be connected to a connection terminal of the battery pack, the microcomputer comprising:
- a processor configured to operate in at least two states, includinga first state, in which the microcomputer sends battery authentication data and battery residual quantity data to the equipment body for processing by the equipment body in a timely alternating manner by serial communication via the connection terminal before an authentication process is completed, anda second state, which follows the first state, wherein the microcomputer sends battery residual quantity data to the equipment body after the authentication process is completed.

Abstract
A battery pack detachably connectable to an equipment body to supply power to the equipment body, the battery pack including a battery cell, a microcomputer for communicating with the equipment body, a connection terminal connected to the microcomputer, a positive power supply input terminal connected to a cathode of the battery cell; and a negative power supply input terminal connected to an anode of the battery cell. After the power of the equipment body is turned on, the microcomputer alternately sends to the equipment body by serial communication via the connection terminal information to be used in authentication processing executed by the equipment body and information to be used in a battery residual quantity count executed by the equipment body. After the authentication processing is complete, the microcomputer sends to the equipment body information to be used in updating the battery residual quantity count executed by the equipment body.
