摘要：An electronic time piece senses and warns the electric residue of a secondarycell having electrodes of conductive polymer to a user during the rapid charge.
The electronic time piece converts a kinetic energy produced by the user's motioninto an electric energy. The electric energy is then outputted from a power generatorcoil as a charging voltage for charging a chemical reaction type secondary cell. Thecharged energy in the secondary cell is used to actuate a time piece circuit for indicatingthe time.
The electronic time piece comprises an electric residue sensor unit which outputs anelectric residue detection signal when the voltage in the secondary cell continues toexceed a reference voltage corresponding to an electric residue in the secondary cell fora predetermined time during the rapid charge.
