Problems solved by technology
The first solution is to add a dedicated control chip, which will increase the cost of the mobile terminal and reduce the competitiveness of the product, and this solution generally uses an increase in the charging voltage such as 9V, 12V, 20V, which reduces the voltage conversion efficiency of the charging circuit and causes serious heat generation. , will greatly reduce the security and reliability of the mobile terminal, and there are security risks
The second solution uses a special vehicle-side charging stand or adapter, data cable, interface and battery, which greatly increases the cost of the mobile terminal and reduces the competitiveness of the terminal. In addition, it reduces the versatility and the user experience is very bad.

The invention relates to a vehicle-mounted terminal quick charging system, method and device. The system comprises a vehicle-mounted charging device and a mobile terminal, and the mobile terminal comprises a main control chip, a detection control circuit and a charging chip; the detection control circuit detects whether the mobile terminal is connected with the vehicle-mounted charging equipment or not; when it is detected that the mobile terminal is connected with the vehicle-mounted charging equipment, detecting whether a signal received by the mobile terminal is a high level or not, and feeding back the signal to the main control chip; if the detection signal received by the main control chip is high level, the mobile terminal is configured to be in a first charging mode, and if the detection signal is not high level, the mobile terminal is configured to be in a second charging mode. According to the invention, rapid charging of the terminal is realized on the premise of low cost. When a user uses the mobile terminal and the vehicle-mounted charging equipment supporting quick charging, the charging time can be shortened by more than half under the condition of the same battery capacity. The cost is greatly reduced, the universality, the reliability and the safety are improved, and the user experience and the product competitiveness are remarkably improved.
Description
technical field [0001] The present application relates to the field of terminal applications, in particular to a fast charging system, method and device for vehicle-mounted terminals. Background technique [0002] With the popularization of 4G communication technology and the advent of 5G, mobile terminals play an increasingly important role in people's lives. From communication, entertainment, photography to learning, payment, mobile terminals penetrate into every field of people's lives, so The performance and functions of mobile terminals are very important to users, and each manufacturer is constantly optimizing and improving the performance and functions of its products to meet the needs of users. As mobile terminals are used in more and more scenarios and frequencies, manufacturers use large-capacity batteries to deal with it, which increases the service life of mobile terminals. However, the charging time of large-capacity batteries is also getting longer and longer, ...
