Problems solved by technology
[0002] Ordinary adapters provide continuous power supply. Even if they are fully charged, they will continue to charge. If they cannot be fully charged, they will automatically cut off the power supply. However, lithium batteries should stop charging when they are fully charged. Overcharging for a long time will cause the battery to heat up and cause the battery to dissolve. Ionization and decomposition, irreversible chemical reactions occur at the two poles of the battery, so that the rechargeable battery will have a decrease in rechargeable capacity, shorten its life, and even explode, with low safety
Moreover, after the adapter fully charges the lithium battery, it cannot intuitively reflect that the charging is complete, and it needs to be seen on the mobile phone.

The invention discloses an intelligent USB adapter, which comprises a power supply module, a USB interface, a voltage detection unit, a state indication unit, a control module and a switch unit. Voltage of a battery of charging equipment is detected via the voltage detection unit, a detected voltage analog signal is sent to the control module, the battery is fully charged when the voltage of the battery is detected to be in a set range, the control module controls the battery to stop being charged and a corresponding indication lamp is driven to be on, automatic power off after full charging of the equipment is realized, charging completion is intuitively displayed as the indication lamp is on, the charged battery is protected, over-charging of the battery can be avoided, shorted life service of the battery can be avoided, and the intelligent USB adapter can be safer to be used by a user.
Description
technical field [0001] The invention relates to charging equipment, in particular to an intelligent USB adapter for charging mobile phones, tablet computers, charging treasures and the like. Background technique [0002] Ordinary adapters provide continuous power supply. Even if they are fully charged, they will continue to charge. If they cannot be fully charged, they will automatically cut off the power supply. However, lithium batteries should stop charging when they are fully charged. Overcharging for a long time will cause the battery to heat up and cause the battery to dissolve. Ionization and decomposition will cause an irreversible chemical reaction at the two poles of the battery, which will reduce the rechargeable capacity of the rechargeable battery, shorten its life, and even explode, resulting in low safety. Moreover, after the adapter fully charges the lithium battery, it cannot intuitively reflect that the charging is complete, and it needs to be seen on the m...
