Embodiment Construction

[0023] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0024] The device's linear charging chip efficiency is proportional to the value of the battery voltage divided by the input voltage. To maintain the high efficiency of the linear charging chip, it is necessary to keep the input voltage and the battery voltage at a small voltage difference (if the voltage difference is too small, the device will not work properly, and the minimum voltage difference to maintain the normal operation of the device is allowed by the linear charging chip of the charged device. scope of work).

[0025] figure 1 A schematic diagram of the principle of the dynamic high-efficiency charging and discharging method between batteries according to a preferred embodiment of the present invention is schematically shown. Such ...

Abstract

The invention provides a dynamic high-efficiency charging and discharging method between batteries. The dynamic high-efficiency charging and discharging method comprises the following step that: a battery compartment power supply management chip sends a voltage carrier through an output power line to inquire a battery voltage of charged equipment; the charged equipment decodes a voltage carrier signal after receiving the voltage carrier, and then adjusts a current on the power line to return a current carrier to the battery compartment power management chip, wherein the current carrier comprises the information of the voltage of the battery of the charged equipment; and the battery compartment power supply management chip receives a current carrier wave transmitted by a charged device by detecting a current, and reduces or raises an output voltage of the battery compartment power supply management chip according to the current carrier wave, so that a difference between the output voltage and a battery voltage of the charged device is in a predetermined range.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a dynamic and high-efficiency charging and discharging method between batteries. Background technique [0002] At present, portable devices on the market often use the battery compartment to charge the device battery. The device is commonly used with a 5V input linear charging chip. The charging efficiency is very low, between 40% and 84%, and the battery compartment is boosted to 5V. There is also a loss of efficiency. , coupled with the limited capacity of the battery compartment, the low-efficiency system greatly affects the battery life of the device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dynamic and high-efficiency charging and discharging method between batteries in view of the above-mentioned defects in the prior art. [0004] According to the present invention, a dynamic high-efficiency charging and disch...
