Problems solved by technology

The lithium battery itself integrates a battery protection board, which provides overcharge, overheating, short circuit, overload, overcurrent and other protections for the battery when the battery is used independently as a charger. However, when the lithium battery is used for a long time, its battery protection board will inevitably age. , the overcharge protection is lost, and it is easy to overcharge and cause personal injury

Embodiment 1

[0023] Embodiment one: if Figure 6 , 7 As shown, in the prior art, when charging smart mobile terminal devices such as mobile phones and tablet computers, the charging port is usually directly connected to the computer 1 or the charger 9 inserted in the power socket 10 through the connecting line 3 to form a charging circuit. In this way, after the smart mobile terminal device 7 is fully charged, the charging circuit will not be cut off automatically, but the overcharge protection of the battery board is provided by setting the battery protection board in the smart mobile terminal device 7. After the growth and aging of the battery, the protective effect on the battery becomes very limited.

[0024] The charging method for preventing overcharging of the smart mobile terminal device in this embodiment specifically includes the following steps:

[0025] Such as figure 1 As shown, the connection port 2 (usually a USB port) on the computer 1 is used as the power connection int...

Embodiment 2

[0028] Embodiment two: if figure 2 As shown, the difference between this embodiment and the first embodiment is that: the charger 9 is used to charge the smart mobile terminal device 7 , and the charger 9 is plugged into the power socket 10 . The control switch 4 is set in the charging line between the charger 9 and the smart mobile terminal device 7, and the control switch 4 receives the audio signal sent by the smart mobile terminal device 7 to represent its charging state, and controls the charger 9 and the smart device according to the audio signal. The opening and closing states of the charging lines between the mobile terminal devices 7.

Embodiment 3

[0029] Embodiment three: as image 3 As shown, the difference between this embodiment and the second embodiment is that the control switch 4 is integrated into the charger 9, so that the user only needs to connect the smart mobile terminal device 7 and the charging device 7 in the same way as the current operation method. 9, so as to realize the effect of optimizing the user's operation experience.

Abstract

The invention relates to the field of intelligent mobile equipment design and accessories, in particular to an anti-overcharging charging method and an anti-overcharging device of intelligent mobile terminal equipment. The anti-overcharging charging method is characterized in that a controller is arranged in a charging line between the intelligent mobile terminal equipment and a charging power supply; a signal connection is arranged between the intelligent mobile terminal equipment and the controller and the controller receives the signals of the intelligent mobile terminal equipment to know the charging state of the intelligent mobile terminal equipment; and the open state and the closed state of the charging line are controlled through the controller. The anti-overcharging charging method and the anti-overcharging device of the intelligent mobile terminal equipment have the advantages that the information of the battery state of the intelligent mobile terminal equipment can be expressed as audio signals which are fed back to the charging device; the charging device can automatically cut off the charging line for charging the intelligent mobile terminal equipment in time when the battery is fully charged, the overcharging situation is avoided, and the service life and the safety of the battery of the intelligent mobile terminal equipment are greatly improved; the structure is very simple, the cost is very low and the use and the popularization are facilitated.

Description

technical field [0001] The invention relates to the field of intelligent mobile terminal equipment design and accessories, in particular to a charging method for preventing overcharging of intelligent mobile terminal equipment and an overcharging preventing device. Background technique [0002] During the charging process, the voltage of the battery will gradually rise with the increase of the stored power. When the stored power of the battery reaches saturation and the electrode material cannot continue to charge, if the charge continues, the electrolyte will be electrolyzed, and oxygen will be generated at the anode. The cathode generates hydrogen gas, which will cause the internal pressure to rise inside the sealed battery and cause damage to the internal structure of the battery. This phenomenon is called overcharging, which is easy to cause overcharging of the battery of the smart mobile terminal device, greatly reducing the battery life. In severe cases, it may even ca...
