Abstract

The purpose of the present invention is to provide a battery power source apparatus that is composed of plural secondary batteries (1). By using the laminated plate as the casing material and extending the anode lead as well as the cathode lead, which are made of metal foil, a secondary battery (1) is formed. Because a circuit board (3) and plural secondary batteries are disposed inside a pack case (2), soldering lands (21) are formed in the drawing out directions of the anode lead (11) and the cathode lead (12) of each secondary battery on the same face of the circuit board. Therefore, each secondary battery can be connected to the circuit board without exerting the bending and twisting force on each of positive and negative leads, which are formed in foil, so as to prevent each of positive and negative leads from being damaged. Because circuit board can be connected in parallel or in series with the secondary battery based on the circuit pattern formed on the circuit board, wiring leads or the like become unnecessary so as to provide superior workability.

The battery and the battery element of the present invention are housed in a wire as a battery power source device for a battery pack including a secondary battery and a circuit board. The secondary battery is formed by stacking thin plates. The conductive substrate and the negative electrode of the metal plate are led out of the casing, and the circuit board is provided with the above-mentioned secondary battery protection circuit and the like. For portable information devices such as laptop computers and portable audio devices, f = t is required to improve the portability of small and lightweight, thin and light source devices according to ancient ## 加加. And even if it is called Lei Er: the key factor of battery secondary batteries such as battery packs and battery packs, the key factor is not too much, especially for the use of II. Therefore, the weight and thickness of power supply devices are extremely demanding. For the project, it ’s imperative to reduce the weight and thickness of the product. In order to achieve the shell material, the laminated sheet coated with the metal layer on both sides of the grease layer is actually obtained by using the electric element to seal the shell material. The secondary batteries inside are lightweight and thin, and the secondary battery is weaker than the secondary battery using the conventional metal box. For example, ', but on the contrary, it uses the secondary lightning = metal foil wire as the positive and negative electrodes for mechanical strength and heat resistance. In particular, when a battery power supply device is configured to increase electricity, in particular, In the case of obtaining a high-voltage secondary battery = f-connected secondary battery, and when it is necessary to pay attention to it, and when the secondary battery is connected, etc., there are battery batteries that are used to obtain the secondary battery. The secondary battery, especially the clock system and the over-discharge Lei A 'group, are included to ensure that the primary battery is free from overcharge.

Description of the invention (2) ^ _____ Secondary battery pack and battery ~ ~ Figure 35 shows that it will be thin by stacking: ^ structure is necessary to take time. The batteries 401 are connected in parallel, and a lithium-ion secondary battery 415, which is a casing, is connected to a conventional-grade battery of a conventional battery with a battery protection circuit in a circuit-based box to manufacture a battery pack. ,,, ° Structure. The battery is housed in the module as described above. The secondary battery is a foil wire. The positive electrode, the positive electrode, and the negative electrode are gold wires that are drawn outward. For example, the copper wires are aluminum wires. In the conventional structure, the winding of a conductive wire and a metal foil made of a thickness of less than or equal to ^^ are difficult to connect with the insulated wire. Here, a positive metal plate 4 1 6 metal plate 416 is connected to both sides of the negative metal plate 4 1 7 and Jiu ^ \, and the positive lead 4U of the negative battery 401 and the positive electrode are stored in the positive metal plate 416. It is connected to the negative metal plate 417. The circuit board of the circuit is used to form a battery protection circuit. Each of the primary batteries 401 is connected in parallel, and the battery protection circuit performs input and output of power. In this structure, the positive lead from the secondary battery 401 cannot connect with the negative lead 412 on the same plane. The second lead is poor, and the positive lead 411 is injured during operation. Concern with the negative lead "I. In addition, due to the connection of the positive lead 4 to the positive metal plate 41 6 'and the connection of the negative lead 4 2 to the negative metal plate 4 1 7 have a front and back relationship, there is a positive lead 411 and The negative metal plate 417 is in contact, and the negative lead 412 is in contact with the positive metal plate 416, and it is necessary to strengthen the insulation between the positive and negative electrodes. In addition, when the metal plates 41 of the positive and negative electrodes are caused by shock and vibration, 41 7 due to injury when in contact with the secondary battery

5. Description of the invention (3) and the shell formed by the thin layer of the plate, and the positive metal plate 416 and the negative gold. It is necessary to fix the secondary battery 401 with the insulating member and the fixing member disposed on the sub-assembly plate 4lj. Therefore, problems such as an increase in working hours are required. ;, And I I have component additions and operations. In addition, the laminated sheet is used as the outer m soft. When using these, "two =, because the shell is vibrating, due to the heavy densities of the power generation elements * 'Power supply The clothing is subject to shocks and causes the secondary battery to move out of the case, causing worries and injury to the case. Broken lead wires and bent adhesive tapes to fix the secondary battery. f This' is generally used on both sides, but in the conventional method pool using a laminated sheet like = ::, the secondary electric element of the shell of the power generation element: scallop is housed in a metal tank through the shell. The force of the secondary battery phase == and the power generation body is not moved, and the power generation contained in it is small, even if the wires from the positive and negative plates of the casing are produced in the casing, it will move. When the secondary battery is fixed at the installation position and there are concerns about bending, peeling off the release paper on both sides of the adhesive tape and the three-sided adhesive tape may cause scratches and scratches, and most of them will affect the reliability of the battery case. Dan I: And, The peelability of the peeling paper is extremely low, and the operability of peeling is extremely low. In addition, when repeated charging and discharging and expansion due to long-term accumulation, the outer shell of the secondary battery is soft, which makes the secondary battery Thickness gauge is increased.

Second, the worry of transmitting adverse effects to the device in which the battery pack is assembled. / 90105927.ptd Page 7 V. Description of the invention (4 ) ^ In addition, the positive side of the secondary battery is especially difficult to lead the positive electrode. Here, there is a method of bonding the front end of the lead of the positive electrode and the negative electrode to the soldering point. However, it is necessary to have In the process of manufacturing the plate ultrasonic bonding wire, when there are low positive and negative lead wires that increase the number of working hours, the front end of the secondary battery has the damage of the weight of the front end wire, such as breakage and bending of the lead wire. In addition, due to the softness of the shell These secondary batteries are required to form a secondary battery and a battery protection circuit. However, since the battery power supply device must be made thinner in the component box, the lead wires of the positive electrode and the negative electrode are provided. These are connected to the fear of wire breakage caused by electric motors. In addition, the advantages of the secondary battery are that the thickness of the circuit board can be reduced due to the use of the secondary battery. At the same time, the planar area can be increased, and the size can be reduced. 4. The object of the present invention is to provide a plate such as nickel-nickel, which is welded to a circuit substrate, and a wire connecting the lead and the negative electrode to the circuit substrate. Ultrasonic bonding is used to remotely weld the plate to the circuit substrate. In this wire bonding method, the problem of the positive electrode and the negative electrode of the secondary battery is caused. In addition, when the foil is used and the strength part is joined with a plate, the number of the second electrode is increased, and the problem of the positive electrode and the negative electrode is easy to occur. Scratches and deformations occur, and in a battery power supply device, a circuit board with many components is integrally formed, and various constituent elements used for this must be housed to hinder and reduce weight. In addition, the circuit board combination of ultrasonic welding when a conductive substrate is made of a metal foil is used to form a battery pack port, and the thin outer side of the secondary battery is damaged. The secondary battery and the wire bonding method of the device filled with the battery pack are hindered. 501291 V.

At this time, the overcurrent protection element 8 fuses by itself to prevent excessive discharge current. This second function is to protect one of the secondary batteries 1 connected in parallel when an internal short circuit occurs. Such an internal short circuit is not only caused by the failure of the battery itself, but also applicable when it is abnormally used. For example, when a primary battery 1 is punctured by a sharp metal, 'because current will flow from the other secondary batteries 1 into the secondary battery 1, a large current is concentrated in one secondary battery 1. If it continues, Words would pose a dangerous situation. Since the overcurrent protection element 8 is connected in series to each of the secondary batteries 1, even in such an abnormal state, the inflow of excessive current is prevented. As the overcurrent protection element 8, a sheet-type overcurrent fuse type fuse is suitably mounted on the circuit board 3, and can be arranged near each of the secondary batteries 1. In addition, PTC elements (Positive Temperature Cof f c i e n t) can also be used for overcurrent protection.
