Problems solved by technology

Here, since the working voltage required by the hardware modules (such as display screens) that require high working voltage is quite different from the output voltage of the battery of the terminal equipment, the output voltage of the battery of the terminal equipment is converted to the high working voltage. The operating voltage of the hardware module will generate a large energy loss, which will adversely reduce the battery life of the terminal device

Abstract

The invention discloses terminal equipment and a power supply method thereof. The terminal equipment comprises a first battery, a second battery and a battery management unit. The first battery is configured to provide a direct-current power supply with first voltage. The second battery is configured to provide a direct-current power supply with second voltage. The second voltage is larger than the first voltage. The battery management unit is configured to obtain the battery state of the first battery and the battery state of the second battery according to at least two threshold values which are respectively set for the first battery and the second battery. The battery management unit controls power supply of the first battery and the second battery according to the battery state of the first battery and the battery state of the second battery.

Description

technical field [0001] The invention relates to a terminal device and a power supply method thereof. Background technique [0002] With the development of technology, more and more hardware modules are integrated on terminal devices such as smart phones, tablet computers or notebooks. Typically, these hardware modules have different operating voltages. For example, hardware modules such as WIFI modules, processors, or Bluetooth modules usually work at lower operating voltages (eg, 3-5V), while hardware such as display screens usually work at higher operating voltages ( For example, 12V-24V). In this case, it is necessary to convert the voltage provided by the battery of the terminal device into an operating voltage suitable for these hardware modules. Usually, the output voltage of the battery of a terminal device such as a smart phone, a tablet computer or a notebook is in the range of 3V~5V, so it is necessary to convert the output voltage of the battery of the terminal...
