Disclosed are a mobile device, a battery management circuit, and a battery management method. The movable device includes an interface for receiving electric energy, a first battery whose positive pole is connected to the interface via the first switch and the negative pole is connected to the reference terminal, the positive pole is connected to the interface and the negative pole is connected to the reference terminal via the second switch and the first battery is connected to the first battery via the third switch. A second battery connected to the positive terminal of the battery, and a control circuit. The control circuit controls the above three switches to make the movable device selectively work in one of the multiple modes. In the single-battery charging mode, the control circuit turns off the third switch, and controls the first and second switches so that one of the batteries is charged by the above electric energy. In the dual-battery series charging mode, the control circuit turns off the first and second switches, and turns on the third switch to charge the first and second batteries with the electric energy. The battery of the mobile device can be flexibly arranged to reduce the size of the device. The device also simplifies and / or omits some circuits to reduce the cost and power consumption of the device.
Description
technical field [0001] The present invention relates to the field of batteries, and in particular, to a movable device, a battery management circuit and a battery management method. Background technique [0002] Mobile devices such as smartphones and tablets use increasingly larger screens and increasingly powerful central processing units (CPUs) and / or graphics processing units (GPUs), so these High-capacity battery for extended runtime. Fast charging of the battery is very important for the end user of the device. [0003] Existing solutions for increasing battery capacity include increasing the size of individual cells. However, this solution may increase the size (eg thickness) of the removable device and reduce the flexibility of the internal circuit and component placement of the removable device. [0004] figure 1 Shown is a schematic circuit diagram of another prior art solution for increasing the battery capacity in the mobile device 100 . exist figure 1 , the...
