Description

1234895 V. Description of the invention (1) The present invention is related to a box φ; a kind of detection battery and a method for managing a pool, and particularly to a device thereof. The method of storing a battery and reserving a preset amount of power is usually provided in * various mobile computers, such as -2 mobile computers, such as notebook computers and tablet computers. For the sake of cost and environmental protection, once there is a battery to provide power for mobile use, the mobile electronic device is generally ### of the battery (hereinafter referred to as the battery). Generally speaking, the battery's power discharge time and its capacity will depend on the battery storage characteristics (recoverable capacity rate, reeQvp hl μ battery storage 夂 M rec〇verable capacity rate). Please two γ, Figure 1, This drawing of the recoverable capacity ratio is to divide a plurality of positive-rolled batteries of the same specification into three groups, which are stored to 0%, 40%, and 100% battery capacity, respectively. These three groups of batteries are stored in an environment of 20 degrees Celsius. At regular intervals, several batteries are randomly selected from the three groups of batteries to test the recovery of the power in their capacity. This is repeated and measured as shown in Figure 1. The battery storage characteristics shown below. The aforementioned method of testing the power capacity recovery ability is to charge the selected battery to 100% and then discharge it at 0.2C (assuming a battery with a capacity of 200 mAH, 1C is 200mAH, because It is discharged at 400 mA from 400 mA to the cut-off voltage (usually 2.5 to 3 V) to calculate the battery capacity. For example, the discharge time is 4.8 hours, and the battery capacity is 40. 0 m A * 4. 8 Η = 1 920πιΑΗ = 96% 〇 Shown in Figure 1 If the battery is charged to saturation (100%), after 12 months

12992twf.ptd Page 6 1234895

After that, its 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 is learned that the battery is charged to 100% before the mobile computer leaves the factory. This battery has the worst storage characteristics at the time of sale; otherwise, if the battery's power capacity is adjusted to 〇%, will be able to achieve the best power valley 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 Japan's original factory charges battery cells to 35% before shipping to Taiwan. Several batteries are assembled with the control circuit board for testing. Before leaving the factory, the battery is charged to 50% by manual control of the power supply and then packed and shipped. Shunda (DynaPack), Celxpert, Simpo, etc. will charge the battery to 50% ~ 60 after testing the battery with a large charge and discharge current instrument 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 battery
