ABSTRACT:
BOTTOMGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to method and system for ensuring lifetime of recharged battery built-in portable electronic device, and also relates to method and system for production line to remain electricity power account of a recharged battery set which built-in a portable electrical device.
2. Description of the Prior Art
Because recharged battery can be long-time used by repetitively charging, traditional battery is gradationally replaced by recharged battery in accordance with both price reduction of charged battery and increased requirement of portable electronic device. In general, specification of recharged battery used by walkman is similar to traditional battery, and also is not built-in walkman but the user must extra buy charged battery before a new walkman is used. By contrast, specification of recharged battery used by portable electronic device, such as notebook computer, is different from traditional battery, and is built-in portable electronic device. Thus, the user acquires both portable electronic device and required charged battery at the same time that the user buys the portable electronic device.
However, for most of production lines, because it is necessary to integrate recharged battery with portable electronic device and to test them as a whole, charged battery is built-in portable electronic device before portable electrical device testing processes are performed. In other words, it is a seldom case that saturated recharged battery is built-in after these portable electrical device testing processes are finished. Therefore, an unavoidable trouble is that account of recharged battery built-in produced portable device, all testing process have been just finished, not only is not saturated (charge is consumed by these processes) but also is not fixed (depends on practical details of undergo processes).
Additional, though relationship between charge account and time relation, which acquired from these testing processes, can be used to assist first user of a portable electrical device in handling how long the portable electrical device can operate before it is necessary to charge built-in recharged battery. But because neither manufacturer not vendor can assure produced portable electronic device can be delivered to an end-user in a short period, and also because that lifetime of a recharged battery is decreased when actual account of electricity power of the recharged battery is remained in a high level or a low level for a long time. An unavoidable deletion is that lifetime of recharged battery of produced portable electronic device is shorten by improper account of electricity power of built-in recharged battery, and then both encumbrance (accessible time of recharged battery is reduced) and trouble (built-in charged battery is difficult to renew) of end-user is increased.
As a summary, because current production line of portable electronic device can not ensure actual account of electricity power of built-in recharged battery is located in a suitable range for long-time conservation, it is desired new method and system for testing and adjusting actual account of recharged battery.
SUMMARY OF THE INVENTION
A main object of the present invention to provide method and system for lengthening lifetime of recharged battery.
It is another object of the present invention to provide a simple and effective method and system for remaining electricity power account of a recharged battery set, which built-in a portable electrical device, without irneglectable extra cost and obvious modification.
One preferred embodiment is a method for ensuring lifetime of recharged battery built-in portable electronic device, at least includes following steps: receive a predetermined range of electricity power; perform an electricity power testing process to measure an actual account of electricity power of a recharged battery that built-in a portable electronic device; and perform an electricity power adjusting process to let the actual account is modified into the predetermined range whenever the actual account is out the predetermined range.
Another preferred embodiment is a system for production line to ensure lifetime of recharged battery built-in portable electronic device, at least includes following steps: receiving means for receiving a predetermined range and a predetermined period; measuring means for measuring an actual account of electricity power of the recharged battery set; determining means for comparing the actual account with the predetermined range and determining whether adjusting the actual account or not; charging means for charging the recharged battery set and to let the actual account is modified into the predetermined range whenever the actual account is lower than the predetermined range; and discharging means for discharging the recharged battery set and to let the actual account is modified into the predetermined range whenever the actual account is higher than the predetermined range.
