Abstract

A battery power supply system consisting of battery card, battery card assembly where battery card slots in, and charger where battery card gets recharged is disclosed. The standardized battery card is designed in light, thin, safe, and user-friendly card configuration to make interchangeability between appliance easy and possible. The battery card assembly is designed either for single or multiple battery cards. In the case of using single battery card, the battery card assembly electrically connects to a power buffer in the electrical apparatus so the user can change their battery card without turning off the electrical apparatus within a certain time interval. In the case of multiple battery cards, the battery card assembly connects power to the electrical apparatus from only one of the battery cards. Until the first battery card is completely discharged, the battery card assembly automatically switches to another battery card without disturbing the electrical apparatus operation.

Description

44715 9 __Case number 88112137__ ± _3-1-M: ___ V. Description of the invention (1) The present invention relates to a battery pack and an electronic device using the battery pack, especially a battery card and the use of the battery card An electronic device assembled. All portable electronic devices today, including portable information electronics, use an internal battery pack as a source of power. The battery pack includes a number of batteries configured in series or parallel to generate the amount of electricity and voltage required for the operation of the device. The earliest minefields were lead-acid batteries. The energy density of this traditional type of battery was low, and the pollution of the environment was serious, so it was gradually eliminated in development. Nickel-cadmium mines (Ni-CD) are relatively superior, but for the latest portable mines and communication devices, its energy is not exhausted. Full, and, by hammer hammer mines The environmental pollution problem caused is also heavy II%. Therefore, in large-capacity countries, it is a strictly controlled alpha nickel thunder tank: the energy density of this battery is twice as high as that of the old nickel-cadmium battery. It is 30-50% higher than the new nickel-cadmium battery. Can it be charged in a high current state? It is a safe and reliable pool in the performance of current redundant portable electrical sub-device thunder tanks. However, its energy density is limited, the environmental problems caused by it also exist, and if the thunder pool has a high self-release rate, and its use life is also limited. The advanced clock ion thunder pool has safety and reliability, and a long life cycle. , High energy features9. Moreover, compared with nickel-hydrogen mines, it has greater flexibility in design and design. Its thickness ranges from 2 mm to 10 mm or more, but the above-mentioned I battery takes A4 size as an example. Its energy density is still limited to 10OWatthrs / 1) ° Based on its relatively high energy storage density, portable information electronics battery The batteries in this group are mainly divided into two categories: nickel-metal hydride batteries (NiMH) and lithium-ion batteries

44715 9 __Case No. 88112137 _ Year and Month Record · Zheng _ V. Description of the Invention (2) Li-ion ◊ · The traditional battery has a cylindrical or angular structure. Generally speaking, the overall structure of a battery pack depends on the shape of the battery. A battery pack assembled from most batteries will be bulky, bulky and expensive? The first figure shows an industrial standard battery pack for a notebook computer. The output of the battery pack 1 containing 9 cylindrical batteries is 44Wh (10.8V X 4.05Ah), and its size and weight are 150 (W) x90 (L) x21 (T) mm and 490g. The battery pack 1 can be operated by a Pentium 300 laptop for approximately 3hrs (180min.). Recent battery pack designs are as thin and light as possible in order to be suitable for thinner and more delicate electronic equipment. The second figure shows a thin and thin battery pack for a notebook computer containing an angular battery. The battery pack 2 includes several angular inner ion batteries with a relatively high weight and volume energy storage density. Compared with the battery pack 1 in the first figure, the battery pack 2 in the second figure has a smaller thickness because of the use of an angular battery, which is usually less than 10 mm. However, smaller batteries have a relatively short battery life because they have less conductive material. Users have also found it difficult to maintain power continuity. If power shortages occur frequently, in some of the worst cases, their data integrity may be compromised. Because of this, users must carry more battery packs than they actually need during a trip, and a laptop computer that is concerned that the battery power is exhausted is usually equipped with only one battery pack. However, for those who use it frequently, their notebook computers may have to be equipped with two battery packs, but their practicality is low due to weight and factors. Most battery packs are designed solely for some kind of sub-equipment, completely ignoring them from all kinds of electronic devices. Users are often limited by manufacturers and are not interchangeable. Sub-equipment manufacturers may borrow a limited supply to compare; = Erzui makes the electronics accessories market $. Right back price control battery attached

Assembly, which can be fitted with a battery card

44715 9 Case No. 88112137 V. Description of the invention (3) Specially designed battery packs are usually recommended by the manufacturer under conditions of use that are easy to respond to the safety of the system.

All of the above disadvantages hinder carrying. The present invention provides a battery pack which is one of the purposes of the present invention, so as to provide a battery pack that can be replaced by a user without power storage capacity. The inventors have solved the problem of relatively reduced shrinkage due to portability. Conventional equipment, the present invention takes the minimum operating time required for battery card-like applications. The second purpose of the present invention is to provide the lowest security battery charger outside the battery power system to charge. Another object of the present invention is to provide users with no need to carry more data loss than when the battery is exhausted. The present invention provides a battery card modification which has special safety considerations and is more dangerous than manufacturing. Recently, the power supply of aircraft seats has been paid attention to, because users check the conditions of the battery itself on the fly. The plan is that when the battery power system that is easy to use and easy to replace is in danger of being interrupted, it is not necessary to turn off the electronic device. The improved battery power system also makes use of small battery packs to increase the use of timepieces. Multi-electricity and electronics are the solution to enable continuous satisfaction — 0 A concern that can reduce public safety, which inconveniences whether the battery card is attached to an electronic device or a charger built into the electronic device.
