System and method supporting hybrid power/battery scheme

Abstract

A system (100, 200, 300, 400, 500) consuming energy provided from a battery (105, 205, 305, 405, 505) including a first power source (105A, 205A, 305A, 405A, 505A) and a second power source (105B, 205B, 305B, 405B, 505B). It may include an energy transferring circuit (120, 320, 420, 520). The energy transferring circuit (120, 320, 420, 520) transfers power of at least one of the first and second power sources (105A, 205A, 305A, 405A, 505A, and 105B, 205B, 305B, 405B, 505B) to the other of the first and second power sources (105A, 205A, 305A, 405A, 505A, and 105B, 205B, 305B, 405B, 505B). The first power source (105A, 205A, 305A, 405A, 505A) is arranged to provide power for at least one high dynamic power operation that instantaneously consumes large currents. The second power source (105B, 205B, 305B, 405B, 505B) is arranged to provide power for at least one static/medium power operation. The first power source (105A, 205A, 305A, 405A, 505A) and the second power source (105B, 205B, 305B, 405B, 505B) are supplying the system (100, 200, 300, 400, 500) simultaneously.

Description

technical field [0001] The invention relates to a power management technical solution, especially a system, method and battery for consuming energy provided by a battery. Background technique [0002] In general, there is still a trade-off between high power density characteristics and high energy density characteristics for recently developed battery cells such as Li-ion batteries. For example, a battery cell characterized by high power density can be used to provide or receive a high level of current instantaneously; however, such a battery cell suitable for high current charging and discharging usually has a low energy density. Conversely, a battery cell characterized by high energy density can be used to output a moderate level of power stably for a long time; however, in high dynamic power applications, this type of battery cell cannot output high power instantaneously. This makes it difficult to design / configure the battery characteristics of an electronic device, suc...

Problems solved by technology

For example, a battery cell characterized by high power density can be used to provide or receive a high level of current instantaneously; however, such a battery cell suitable for high current charging and discharging usually has a low energy density

Conversely, a battery unit characterized by high energy density can be used to output a medium level of power stably for a long time; however, in high dynamic power applications, this kind of battery unit cannot output high power instantaneously

This makes it difficult to design / configure the battery characteristics of an electronic device that is used to perform different applications / operations that would correspond to different loads, such as a portable electronic device

For example, some applications / loads need to consume a high level of power momentarily to achieve high performance, while some applications and / loads may consume a static / moderate power for a long time
