METHOD FOR SELECTING BATTERY CELL IN ACCORDANCE WITH DISCHARGE CAPACITANCE RANK
It is possible to set a standard discharge feature of a battery cell expressed by a discharge capacitance difference based on a state when the battery cell is discharged to a discharge end voltage for each of ranks. According to the standard discharge feature, it is possible to obtain a discharge capacitance width for selecting a battery cell having a discharge capacitance causing no danger of excessive discharge when a set of cells of the specification corresponding to the rank is discharged to a predetermined discharge end voltage. This discharge capacitance width is set as an allowance width of the same rank serving as an index for selecting a battery cell so as to measure a discharge feature of each of battery cells. The battery cells having discharge features within the allowance width are selected as battery cells belonging to the same rank. Thus, it is possible to select battery cells in accordance with specification and exclude a battery cell which causes excessive discharge when arranged in a set of cells.

Disclosed is a multilayer tube having a plurality of resin layers, wherein an intermediate layer among the resin layers is composed of an acid-modified resin layer which is modified by introduction of a functional group and at least one of the resin layers is a barrier layer composed of an aromatic polyamide such as PA9T. Consequently, a multilayer tube having good low permeability can be obtained from a low-cost resin material without using an expensive high functional resin such as a fluororesin.
A slit (12) extending in the longitudinal direction is formed in the main body of a connection plate (10) and thin coupling portions (14) which can be blown out with an instantaneous reactive current during welding work are formed at the opposite ends of the main body of the connection plate (10) where the slit (12) ends, thus forming a closed slit. Consequently, impact of the reactive current is reduced, stabilized welding is ensured even when copper is a main material, and handling performance and workability of welding are enhanced.
A plurality of cells are connected into a cell set by a connecting plate (10). The connecting plate (10) has a welding bead portion (14) in the welding portion of its body. A part of the whole of the welding bead portion (14) forms a portion having a higher electric resistance than a base material of the connecting plate body. Thus, even when using a material having a small intrinsic resistance and a high conductivity such as copper, it is possible to assure sufficient welding intensity between the cell and the welding plate without excessively increasing the welding current.
A welding process is divided into a preliminary energizing process and a regular welding process. During the preliminary energizing process, prior to regularly welding a connection plate to a battery, the electrode of a resistance welding machine is used to press the connection plate to the battery cell, and a current smaller than that used for a regular welding is delivered for a time shorter than an energizing time for the regular welding; and during the regular welding process, a specified magnitude of current required for the regular welding is delivered for a specified time with the pressing by the electrode of the resistance welding machine kept sustained to weld the electrode to the battery cell. Accordingly, a stable welding is possible without a welding current being affected by a variation in reactive current.

The covering films are composed of a melt plating film (12), a chemical conversion coating film (14) on the outer side of the plating film, and a thin PA resin film (18) as the outermost film.

In the method, the secondary battery is fully recharged, and directly after completion of recharging, preparation discharge of a prescribed discharge current is performed for a short period of time.
Considering that there is a time lag between the moment when discharge of a secondary cell is completed and the moment when the temperature in the cell reaches its peak, display of discharge completion and the display of appropriate time for discharge start are performed at an appropriate timing. After charge is completed, the cell temperature change is monitored according to a predetermined judgment start reference so as to judge whether the temperature is lowered to an appropriate temperature range for discharge start. When the temperature has reached the appropriate temperature range for discharge start, it is displayed that discharge is enabled.
