As shown in fig. 2, fig. 2 is a schematic flow chart of a method for quickly charging a vehicle-mounted terminal according to an embodiment of the present application, where the overall flow is as follows: the main control chip detects whether a vehicle-mounted charging device is inserted into the mobile terminal, if the vehicle-mounted charging device is inserted into the mobile terminal, then detects whether a detection signal received by the mobile terminal is high, if the detection signal is a high detection control circuit, detection information is fed back to the main control chip, the main control chip controls DP, DM and 5V passages in the detection control circuit to be communicated and cuts off DP, DM and USB interface passages, and in addition, the main control chip controls the charging chip to rapidly charge the mobile terminal by 5A; and if the detection signal received by the mobile terminal is detected to be low, the main control chip controls the charging chip to charge the mobile terminal by 500 mA. If no vehicle-mounted charging equipment is inserted into the mobile terminal, the main control chip controls the detection control circuit to cut off the DP, DM and 5V access, and communicates the DP, DM to the USB interface, and then detects whether a detection signal received by the mobile terminal is high or not, if so, the main control chip controls the charging chip to charge the mobile terminal by 500mA, and if not, the main control chip controls the charging chip to discharge the mobile terminal by 1A. In the embodiment, the mobile terminal determines whether to perform quick charging or discharge other equipment according to different signal levels received by different inserted equipment, so that the cost is reduced, the universality is improved, and the quick charging time is shortened.
The vehicle-mounted charging device in the embodiment of the application comprises a charging seat or an adapter on the vehicle. It should be noted that, in the embodiment of the present application, the main control chip, the detection control circuit, and the charging chip are disposed in the mobile terminal, or disposed in the vehicle-mounted charging device, or disposed as a charger bank having a function similar to that in the prior art, and connected to the vehicle-mounted charging device and the mobile terminal as an independent fast charging device.
Specifically, as shown in fig. 3, fig. 3 is a circuit diagram of a USB interface of a mobile terminal according to an embodiment of the present disclosure, where the interface selected in the embodiment is a common Mini-USB interface, including but not limited to other types of charging interfaces of the mobile terminal.
The detection method comprises the steps that whether the vehicle-mounted charging equipment is inserted into a USB interface of the mobile terminal or not is detected by the detection control circuit, whether DP and DM in the control circuit are in short circuit or not is detected, and when the detection control circuit detects that the terminal is connected with the vehicle-mounted charging equipment, the DP and the DM are in short circuit together by the vehicle-mounted charging equipment.
When the vehicle-mounted charging equipment is detected to be inserted into the mobile terminal, whether a detection signal received by the mobile terminal is high is detected, and the detection method comprises the following steps: when the vehicle-mounted charging equipment is inserted into the mobile terminal, a signal received by an ID pin in the detection control circuit is detected, if the ID detection signal is high, the main control chip controls the level of the ID detection signal to be increased, so that an NMOS pipe M1 in fig. 3 is conducted, DP, DM and 5V paths are communicated, and the detection control circuit of the mobile terminal is connected with the power supply of the vehicle-mounted charging equipment.

The main control chip controls the charging chip to perform 5A charging, so that 5V5A quick charging is realized. The embodiment greatly shortens the charging time under the condition of low cost, and simultaneously improves the reliability and safety of the mobile terminal during quick charging because the charging voltage is not improved.
When the vehicle-mounted charging equipment is inserted into the mobile terminal, a signal received by an ID pin in the detection control circuit is detected, if the ID detection signal is not high, the mobile terminal does not need to be charged quickly, the main control chip also controls GPIO1 in the detection control circuit to output a high-level signal to enable the NMOS tube M4 to be switched on, and simultaneously controls GPIO2 in the detection control circuit to output a low-level signal to enable the NMOS tube M2 and the NMOS tube M3 to be disconnected. The difference is that the main control chip controls the charging chip to perform 500mA charging without performing quick charging, so that the mobile terminal can keep sufficient electric quantity. In the embodiment, the mobile terminal configures the charging mode according to the battery state, so that the user experience is improved.
If it is detected that the vehicle-mounted charging device is not plugged into the mobile terminal, for example, a storage device and the like, the mobile terminal does not need to be charged, the GPIO1 in the detection control circuit is controlled by the main control chip to output a low level signal to separate the NMOS tube M4, and meanwhile, the GPIO2 in the detection control circuit is controlled to output a high level signal to conduct the NMOS tube M2 and the NMOS tube M3, so that the DP, the DM and the USB interface are communicated, and the DP and the DM of the interface are not communicated with 5V to cause damage to the USB interface, and further normal USB communication and information transmission can be performed. The detection control circuit detects whether the signal received by the ID is in a high level again, if the signal is in a high level, the high level main control chip controls the charging chip to carry out 500mA charging, and the common mode charging can be carried out while information is transmitted; if the current level is not high level, the mobile terminal needs to work as a main device, other devices needing to be charged are accessed, the ID detection signal level is pulled down by the inserted terminal device, and the main control core needs to control the charging chip to perform 1A discharging, so that the normal work of the other devices can be ensured. Circuit design is simple in this embodiment, and occupation space is little, and the function is various and stable, and software and hardware combines to realize, can guarantee mobile terminal operation's reliability and security, can promote user's use impression again.
