がある。By the way, in any of the secondary batteries, charging and discharging are the main functions.
In addition, for the safety of handling and use, the end voltage of charge and the end voltage of discharge are set as limits, and charging and discharging are performed at voltages within this limit range. In charging the secondary battery, it is generally known that the temperature of the secondary battery itself affects the charging efficiency. That is, as the charging (progress) of the secondary battery progresses, the battery temperature rises due to agitation heat from the charger device and heat generation of the secondary battery 1 itself. Since it is likely to occur, not only is it difficult to achieve the required charging, but there is a risk of damage (damage) to the secondary battery itself.

供されているのが実状といえる。To explain this point more specifically, in the case of the charger device having the configuration shown in FIGS. 3 and 4,
The bottom surface of the recessed portion 1 of the battery support 2 is fitted and mounted so that the lower surface of the secondary battery to be charged is in close contact, so that heat radiation on the secondary battery side to be charged is significantly limited, and the charger device is installed. The heat generated by the secondary battery and the heat generated by the rechargeable secondary battery itself tend to be trapped. Therefore, when charging is controlled by using the rise and progress of the battery temperature as the charging progresses as a guide, the actual purpose is to prevent or avoid damage or damage to the secondary battery due to overcharging, but in reality Even if the battery has not reached the charging level, the charging is stopped (terminated), and it can be said that the battery is actually used as a driving power source without being sufficiently charged in practical use.

る。In the present invention, the secondary battery to be charged is mounted / supported in a non-contact manner (with a space portion) on the surface of the battery support. In other words, in the charging process, while avoiding agitating heat of the empty charger device, the heat generated by the rechargeable secondary battery itself is easily dissipated. The possibility that heat will be trapped between the battery and the surface of the battery support is completely eliminated. Here, the heat from the outside that contributes to the increase in the charging temperature in the secondary battery can be easily dissipated, and the increase in the charging temperature can be controlled to a normal state because it is necessary to charge the secondary battery to be charged. Since it means that the secondary battery can be efficiently carried out, it greatly contributes to the efficient use (use) of the secondary battery or the extension of the life.

It should be noted that the notches of the side walls forming the heat dissipation path 9 do not necessarily have to face each other as long as the required heat exchange can be performed, and when the notches forming the heat dissipation path 9 are formed on the side walls, they are not covered. Considering workability when fitting and mounting the rechargeable secondary battery, for example, it is preferable to select the side on which the locking body 10 (described later) is installed. Further, the heat dissipation path 9 may be a so-called heat sink (heat dissipation using a metal plate) method, or a combination of this heat sink method and convection method, instead of the convection method.

In this state, the secondary battery to be charged is fitted and mounted in the recessed portion 5 of the battery support body 6 by a distance (forming a space portion) from the bottom surface 5a by the height of the step 5b, and this distance is maintained. Since the region (space) can exchange heat by convection, heat generated by the charger device and heat generated by charging the secondary battery to be charged can be easily dissipated. In other words, in the charging process, when the charging is controlled by the battery temperature, it is possible to avoid undesired and unexpected heat accumulation in the secondary battery to be charged, and it is possible to detect and detect the battery temperature corresponding to the end of charging. Therefore, the required charging can be sufficiently achieved, and the secondary battery can have a long life.
