The invention discloses a method for group matching of power lithium-ion rechargeable batteries. The method comprises the following steps: one-step charge and discharge detection is conducted to the power lithium-ion rechargeable batteries and the batteries with capacities larger than lower limit capacity are taken as acceptable batteries; the acceptable batteries are charged to a state with 50-90 percent of rated capacity and the rechargeable batteries with acceptable voltage drop are sorted; the obtained acceptable batteries are fully charged and are connected in parallel for at least 4 hours to enable the voltage difference between any two rechargeable batteries to be less than or equal to 1mV; the obtained rechargeable batteries are connected in series to discharge, the voltage of each rechargeable battery during discharge is acquired and recorded, and the discharge is stopped when the voltage of any battery reaches cutoff voltage; and a voltage difference standard is set according to the number of series batteries required for group matching and the battery voltage at the moment of discharge cutoff, and the batteries with voltage differences within the preset range are matched into a group. Since the parameters of the batteries are measured and sorted under the simulated battery use conditions and the single rechargeable batteries with close characteristics are sorted, the quality of the group matching is improved.

Provided is a support tool for supporting a flexible component. The support tool for a flexible component is foldable without impairing reliability of the flexible component. The support tool has a region in which two different hinges overlap, and in the region, a bending operation is possible in only one direction from a state of forming a plane. Thus, even when an unintended reverse-direction bending stress is applied to the region, it is possible to protect the flexible component or the support tool. In addition, two hinges have mechanisms for correcting the positions of each other, so that it is possible to perform a stable bending operation.

The invention relates to an embedded type electronic device with an electricity-saving function and an electricity-saving method thereof. The embedded type electronic device comprises an operation system and a microprocessor, wherein the microprocessor is used for detecting the electric quantity of a battery and outputting an interrupt signal to the operation system when the electric quantity of the battery is equal to warning electric quantity. After the operation system receives the interrupt signal, the operation system can wake up the embedded type electronic device in an electricity-saving mode and update the state of the battery. Therefore, the invention can reduce the frequency of updating the state of the battery so as to reduce the electric quantity consumption of the battery andachieve the electricity-saving effect. Under the operation of the same time range, the times of updating the electric quantity of the battery of the invention are obviously less than that of a traditional method.
