A dual-battery control device and method for a mobile terminal

Abstract

The present invention discloses a mobile terminal dual-battery control device and method. The dual-battery control device is connected with a main battery and a secondary cell and comprises a main battery detection module, a secondary battery detection module, an enabled module and a control switching module. The main battery detection module detects the size of the main battery voltage and output the first detection signals corresponding to the level. The secondary cell detection module detects the size of the secondary cell voltage and outputs the second detection signals corresponding to the level. The enabled module outputs outage signals according to the input instruction. The main battery supplies power when the control switching module determines that the main battery has electricity supply according to the high-low level of the first detection signals and the second detection signals, the secondary cell supplies power when the control switching module determines that the main battery has no electricity supply and the secondary cell has the electricity supply, so that the man battery power supply is automatically switched to the secondary cell power supply when the main battery has no electricity supply, and the main battery can be replaced in the turn-on state. When the secondary cell supplies power, the mobile terminal can be restarted according to the outage signals to solve the problems of crashing of the mobile terminal or system faults.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a dual-battery control device and method for a mobile terminal. Background technique [0002] At present, mobile terminals such as mobile phones and tablets are used more and more frequently in people's life and work. When the battery power of the mobile terminal is exhausted and the battery cannot be charged or replaced in time, the shutdown of the mobile terminal will inevitably affect the use and work of the user. For example, when some practitioners in specific positions (such as couriers and supermarket sweepers) use mobile terminals to work, when the battery is dead and needs to be replaced, they hope that the system can complete the battery replacement operation without shutting down the system to avoid shutdown. data loss so that we can work more efficiently. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the i...
