Description

200539494

The technology to which the invention belongs The present invention relates to a battery management method, a detection battery, and a device reserved for storing the battery. In the prior art, and in particular, a method for setting a predetermined amount of power, an automatic / electronic device (such as a notebook computer, a tablet PC, and a mobile battery) usually has a battery to provide a mobile power supply. For cost and environmental considerations, all of its mobile electronic devices use rechargeable batteries (hereinafter referred to as batteries). also

Generally speaking, the capacity of a battery will gradually decrease as the battery discharges. Figure 丨 illustrates the storage characteristics (recoverable capacity rate) of a typical rechargeable battery. Ancient Master Refer to Figure 1. This drawing of the recoverable capacity rate is divided into a plurality of regular batteries of the same specifications into three groups, which are charged to 0%, 40%, and 100% of the battery capacity and stored. All three batteries are stored in an environment of 20 degrees Celsius. At regular intervals, several batteries were randomly selected from these three groups of batteries to test the gray capacity of the power capacity. This was repeated and the battery storage characteristics shown in Figure 1 were measured. The aforementioned method of testing the power capacity recovery capability is to charge the selected battery to 100% and then discharge it at 0.2C (assuming that a battery has a capacity of 2000mAH, 1C is 2000mAH, so 0.2C is 4 〇〇mA discharge) to the cut-off voltage (usually 2.5 ~ 3V), and calculate the battery capacity. For example, the discharge time is 4 · 8 hours, and the capacity of the battery is 400 m A * 4. 8 Η = 1920mAH 96% 〇 Figure 1 shows that if the battery is charged to saturation (100%), after丨 2 months

12992twf.ptd Page 6 200539494 V. Description of the invention (2) The recoverable capacity is about 90%. If the battery is completely discharged (0%), after 12 months, the battery can almost completely restore its original power capacity. It was learned that 'If the battery is charged to the mobile computer before it is released, this battery has the worst storage characteristics at the time of sale; otherwise, if the battery power is adjusted to 0% before leaving the factory, , Will be able to achieve the best power capacity recovery capacity at the time of sale. However, considering market demand, it is usually necessary to leave the battery with a preset power capacity (usually 35% ~ 60%) before leaving the factory. Known battery management varies from manufacturer to manufacturer. Sanyo, Sony, and other Japanese manufacturers charge the cells to 40% and 55% before shipping them to Taiwan. After several battery cells are assembled with the control circuit board for general testing, they are directly packed into the factory and shipped without any battery power capacity management. Panasonic said that the original factory charged the battery cells to 35% before shipping them to Taiwan. Several battery cells were assembled and tested with the control circuit board, and the batteries were manually charged to 50% by the power supply unit before shipment before shipment. Shunda (DynaPack), Celxpert, Simpo, etc. will charge the battery to 50% ~ 60 after testing the battery with a large charge and discharge device that can monitor the battery voltage and current charge and discharge. % And then boxed and shipped. In summary, if the battery is fully charged and then shipped with the mobile computer, it will have poor power storage characteristics over time. When the customer temporarily requires that the battery in the mobile computer needs a special specified power capacity when it leaves the factory, the battery shipment capacity control must be performed manually, which affects the factory shipment time and increases labor costs. Moreover, in the conventional technology, the electric second

Embodiment 2 FIG. 2 is a flowchart of a battery management method using a mobile computer (such as a notebook computer) as a detection / adjustment platform according to a preferred embodiment of the present invention, so that the battery can be charged when the battery leaves the factory. Discharge characteristics are detected and maintained at a basic low power inventory. Therefore, even if the battery is left unused for a period of time after it leaves the factory, the battery can still maintain a better recovery capability similar to the original capacity. Referring to FIG. 2, step S210 is first performed, that is, setting a time interval CT (battery barging time limited), a saturated power capacity level FC (battery fuU capacity), and a preset power capacity level Lc (battery discharged limited capacity).

Before the mobile computer leaves the factory, it usually takes two days to perform

200539494 V. Description of the invention (9) Serial inspections and tests. During this period, the battery under test in the mobile computer whose power capacity has been adjusted to a preset power capacity level LC will consume its power over time. Therefore, step S244 is to compare whether the power capacity information team is smaller than the preset power capacity level LC at any time. When the power capacity information team is less than the preset power capacity level LC, step S245 is performed to charge the battery to be tested. The relationship between the power capacity information BC and the preset power capacity level LC is detected at any time during the charging process (step S246). If the power capacity information BC has not reached the preset power capacity level LC, step s245 is repeated until the power capacity information BC reaches the preset power capacity level LC, and the process returns to step S243. Therefore, during the inspection / test period before leaving the factory, until the packaging leaves the factory, the mobile computer can grasp the power capacity of the batteries. Here is another embodiment according to the present invention.

Please refer to FIG. 3 ′ First, step S310 is performed, that is, the preset power capacity level LC is set. Then step S320 is performed to adjust the power capacity of the battery to be tested to a preset power capacity level LC. It reads the power capacity information BC of the memory of the battery module under test, and compares the obtained power capacity information BC with a preset power capacity level LC. If the two are not equal, the charge capacity and discharge operation are used to adjust the power capacity of the battery to be tested to a preset power capacity level LC °. The above step S3 20 in this embodiment may be implemented by referring to the following steps, for example. First, step S321 is performed, that is, the power capacity information BC is checked. Compare power capacity information BC and preset power capacity level LC (step

When the power capacity information BC is greater than the preset power capacity level! ^, The battery to be tested in the mobile computer is discharged (step S3 23). During the discharging process, step S322 is repeatedly performed until the power capacity information BC reaches the preset power capacity level LC. Then proceed to step §324 to compare the power capacity information BC and the preset power capacity level! ^. When the power capacity information Bc is less than the preset power capacity level LC, the battery to be tested in the mobile computer is charged (step S325). During the charging process, step S324 is repeatedly performed until the power capacity information BC reaches the preset power capacity level! ^ And then returns to step S321.
