With reference to Fig. 3, insert in the use of the portable terminal computer behind the battery 100, in order to calculate the battery allowance value, EC102 reads the margin value of above-mentioned battery 100, and is stored in (S300) among the EC102RAM.Then, above-mentioned EC102 notice battery management module 104 battery allowances change (S302).
After battery management module 104 was received the notice of above-mentioned battery allowance change, in order to obtain revised battery allowance information, battery management module 104 required EC102 that battery allowance information (S304) is provided.
Above-mentioned EC102 calculates revised battery allowance (S306) according to the total electric weight and the margin value of total electric weight of the initial stage of battery 100 and the battery in the battery use 100.
Above-mentioned battery management module 104 is utilized the battery allowance value through revising that above-mentioned EC102 provides, and utilizes total charge value of initial stage of battery 100, obtains battery allowance number percent (S308).
By above-mentioned Fig. 2 and Fig. 3, understood whole process through the battery overmeasure computation method of revising, below, with reference to Fig. 4, will the battery overmeasure computation method of portable terminal computer in the embodiments of the invention be elaborated.
Fig. 4 is among the present invention, calculates the process synoptic diagram of the battery allowance ratio of process correction by total electric weight of battery initial stage.
With reference to Fig. 4, serve as that the basis describes battery overmeasure computation method with concrete numeral.
Below, enumerate out through required data in the battery overmeasure computation method of revising with above-mentioned: total electric weight of the initial stage when battery has just inserted; Total electric weight of battery and surplus that system measures when using in real time; With these three data is that the basis is specifically described.
Suppose that the total charge value of initial stage when battery has just inserted is 100, the total charge value that records in system's use is 90, calculates the actual battery surplus.
At first the battery 100 insertion situations of portable terminal computer are judged (S400).
After battery 100 inserted, EC102 at first monitored the state of battery 100, and total charge value of the initial stage of calculating (S402).
Total electric weight of needed initial stage of the inventive method and current total electric weight are provided with, and when just inserting battery, total electric weight of initial stage and current total electric weight are set at equal.
Behind the total electric weight of counting cell, again the surplus of battery is calculated (S406).
That is to say that above-mentioned EC102 offers above-mentioned battery management module 104 with the battery allowance data after confirming battery allowance, above-mentioned battery management module 104 is used to calculate battery allowance number percent (S404) from the surplus of EC102 and total voltameter of initial stage.Computing formula as shown in the formula:
Battery allowance number percent (%)=(total electric weight of battery allowance/initial stage) * 100
That is, total electric weight of initial stage=100, battery allowance=72 o'clock,
72/100×100％＝72％
As mentioned above, all utilize the method all the time, suppose that the total electric weight of battery immobilizes and equal 100, only need read battery allowance numerical value calculates both ratios.
But in fact battery can change along with service time, and total electric weight of initial stage 100 can constantly change, i.e. reducing gradually is so need calculate than following formula value accurate values more.
In order to calculate more accurate battery allowance, below we are elaborated.
Above-mentioned EC102 carries out periodic monitoring to battery, and whether the surplus of judging battery changes more than certain numerical value, and is notified to battery management module 104.
That is, with differing of previous surplus of battery and existing surplus, a value of setting in advance more than or equal to the user is judged (S408).
Above-mentioned EC102 offers total charge value of initial stage of battery management module 104 when utilizing the total electric weight and the surplus of the battery 100 that reads and inserting battery, just can calculate the battery allowance value of correction, and provide it to above-mentioned battery management module 104.Its concrete calculating formula following (S410, S412, S414).
Battery allowance value=total electric weight of battery initial stage * (the total electric weight of revising of battery allowance/battery)
That is, total electric weight of initial stage=100, total electric weight=90 in the use, surplus=72 o'clock,
100 * (72/90)=80 (the battery allowance value of correction)
Obtain the battery allowance value of correction according to top computing formula after, above-mentioned battery management module 104 is utilized battery allowance value and total charge value of initial stage of the above-mentioned correction of reading, and calculates actual battery surplus number percent.
(80/100) * 100%=80% (actual battery surplus number percent)
From the top result who draws as can be seen, when the total electric weight numerical value that changes was 90, the battery allowance number percent that draws was 80% rather than 72%.
According to such computing method, demonstrate the actual surplus number percent of battery (S416).
Whether process, portable terminal computer unload is judged (S418).
If when battery does not unload, the battery allowance situation can be imported into, carry out battery allowance calculation process (S420) again.
