Description
Technical field
The present invention relates to electronic technology fields, more particularly to a kind of dress of electronic equipment standard configuration charger for identification
It sets.
Background technique
With the continuous development of rapid nitriding, the type of quick charger will be more and more, and quick charger can
To use relatively high power for example to carry out quick charge to mobile phone with conventional 5V voltage, high current, or with high pressure (9V, 12V etc.
Deng), low current to mobile phone carry out quick charge.
In existing mobile phone high-voltage high-speed charging technique, quick charger all can backward compatible 5V output voltage, so as to
To carry out the normal charge of 5V voltage to the mobile phone for not supporting high-voltage high-speed to charge, quick charger end passes through USB
The data-signal and mobile phone terminal of (Universal Serial Bus, universal serial bus) data line carry out handshake communication, communication
High-voltage high-speed charging just exports 9V voltage or higher voltage and carries out quick charge to mobile phone after success.It is filled in mobile phone high-voltage high-speed

If standard configuration charger works under the working condition of excess, the effect that quick charge is not achieved may result in, or even occur
Safety accident.
The second, the quality ginseng of quick charge product is time uneven currently on the market, when using the undesirable non-standard configuration of quality to fill
When electric appliance, it would be possible to user's person property be caused to be encroached on.
Third, due to mobile phone terminal and quick charger end need to carry out by certain specific communication protocol to shake hands it is logical
Letter, and communication protocol is very diversification, when using non-standard charger, after mobile phone is communicated with charger, non-standard configuration fills
Electric appliance can not necessarily export user's required voltage.Such as when user needs quick charger to export 9V voltage,
Non-standard charger outputs 12V voltage, this, which is possible to will lead to mobile phone, is damaged, or even other more dangerous feelings occurs
