The present invention relates to a battery charger / discharger having a detachable connector that can be conveniently operated.

In general, the battery is to obtain electrical energy by using a chemical or physical reaction, such a chemical battery is divided into a primary battery and a secondary battery.

Here, the primary battery uses the electrical energy generated by the chemical change of the material by putting the active material near the electrode in advance, and when the chemical change of the active material is over, the primary battery cannot be regenerated and used as a representative example of the primary battery. A battery is mentioned.

In addition, the secondary battery is to discharge the electrical energy to supply the electrical energy to the battery after the action material changes, that is, to enable the action material to be regenerated, a representative example of the secondary battery is a storage battery. . At this time, the storage battery is a device that can be used as a power source by generating a direct-current electromotive force by a chemical action composed of a positive and negative electrode plate and an electrolyte. Examples of such accumulators include lead acid batteries, alkaline batteries and lithium batteries. Lithium batteries, which have the advantages of high energy density, light weight, high voltage, pollution-free, high power, high speed charging and excellent lifespan, are in the spotlight. The lithium battery is classified into a lithium ion battery, a lithium ion polymer battery and a lithium metal polymer battery.

The lithium battery has a principle that lithium ions in the positive electrode active material escapes and are stored and stored in the carbon layer as the negative electrode active material when charged, and that lithium ions stored in the carbon layer return to the positive electrode active material layer when discharged. It is to use.

On the other hand, as an example of the battery manufacturing process, when describing a manufacturing process of a lithium battery having the principle and function as described above, the hard to be assembled in the case after the circuit, terminal or connecting parts to the bare cell (couple cell) It consists of a hard pack process and a charge / discharge process of charging and discharging the hard pack. Here, the shape and shape of the battery is determined according to the use and required characteristics of the product during the hard pack process, the performance of the battery is determined and determined whether or not the battery during the charge and discharge process.

During the charging and discharging process of the manufacturing process, a charge / discharger for charging and discharging the battery is used as a production facility. Since charging and discharging for about 10 hours is required for each battery, the charger / discharger charges and discharges a large amount of batteries at one time. There is a need for a structural need to increase the integration of charge and discharge channels and to minimize the installation space.
