The invention discloses an Al-Fe-Cu-Mg-Sb aluminum alloy for an automotive wire, a manufacturing method of the aluminum alloy, and a wiring harness made of the aluminum alloy. The Al-Fe-Cu-Mg-Sb aluminum alloy for the automotive wire comprises the following ingredients in percentage by weight: 0.2-1.4wt% of Fe, 0.01-0.5wt% of Cu and Mg, 0.001-0.2wt% of Sb, and the balance of Al and inevitable impurities. The mechanical strength and the tensile properties of the alloy can be improved by adding an Fe element; the high temperature creep resistance also can be obviously improved by Fe; the anti-fatigue performance of the alloy is improved; the strength and the high-temperature creep properties of the alloy can be improved by adding Cu and Mg; the anti-fatigue performance can be improved; the yield limit of the alloy can be improved by adding Sb; meanwhile, the alloy has superplasticity, so as to be drawn into a very thin alloy wire.

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.

The invention discloses a sectional travel characteristic pneumatic actuator device of a turbocharger, which includes an upper casing and a lower casing, wherein a rubber diaphragm is arranged between the upper and the lower casings, and divides a cavity between the upper and the lower casings into two cavities, namely a first cavity and a second cavity, that are not communicated; a diaphragm seat is arranged in a position inside the second cavity and near to the rubber diaphragm; an auxiliary core bar is connected onto the diaphragm seat; and springs with different elasticity coefficients are mounted on the auxiliary core bar. The sectional travel characteristic pneumatic actuator device can realize the matching of different travel characteristics, so that the performance of the supercharger is adjusted to the optimum as far as possible.
