Problems solved by technology

[0013] However, the voltage level of the power supplied from the battery packs 200a and 200b is fixed to a single value in the conventional electronic device, and the power having the single value of the voltage level becomes the power for driving the respective electronic parts of the system, by This leads to inefficiency
[0014] For example, the voltage level of the power supplied to the electronic device from the battery packs 200a and 200b is 14.8V, and the system power supply should convert the power of 14.8V to a voltage level (e.g., ±12V) for driving the various electronic components of the system. , ±5V, ±3.3V, ±1.5V), resulting in large power losses when converting power to ±3.3V, ±1.5V which are significantly different from 14.8V
[0015] Even though the voltage levels of the power supplied from the battery packs 200a and 200b are adjusted, the battery packs 200a and 200b cannot effectively comply with electronic devices that require power at different voltage levels

Abstract

A battery pack and an electronic device that outputs a plurality of powers having different voltage levels from each other using the battery pack. The battery pack includes: a power supply including a plurality of battery cells and outputting battery power of a plurality of different voltage levels through a combination of the battery cells; and a plurality of power output terminals connectable to an electronic device and supplying respective battery power to the electronic device.

Description

technical field [0001] The present invention relates to a battery pack and an electronic device using the battery pack, and more particularly to a battery pack and an electronic device using the battery pack to output power of multiple different voltage levels. Background technique [0002] As portable electronic devices such as cellular phones and portable computers have been developed, secondary batteries are being actively researched. [0003] Examples of such secondary batteries include nickel-cadmium batteries, lead storage batteries, nickel-metal hydride (NiMH) batteries, lithium-ion batteries, lithium-polymer batteries, lithium-metal batteries, and zinc-air batteries. [0004] The secondary battery includes a battery package together with a charging / discharging circuit. The secondary battery is charged / discharged through the terminals of the battery pack. [0005] figure 1 with figure 2 Configurations of conventional battery packs 200a and 200b are shown, respect...
