Embodiment Construction

[0018] The battery pack capable of preventing short circuit (Short) according to the present invention will be described in detail below with reference to the accompanying drawings.

[0019] First, the present invention is applicable to battery packs mounted on portable electronic devices. As shown in Figure 1, the battery pack of the present invention is made up of battery, primary protection integrated circuit 11, discharge FET12, charging FET13, secondary protection integrated circuit 14, fuse 15, thermistor (Thermistor) 16 and switch FET17 etc.

[0020] The above-mentioned battery 10 is composed of a plurality of battery cells (Cell), for example, 6 battery cells (Cell) capable of charging / discharging at 4.2V, and every three are connected in parallel to be used as two series-connected 2S3P (2 Serial 3 Parallel) batteries.

[0021] The primary protection integrated circuit 11 detects the voltage across the cell (Cell) included in the battery 10, and performs the first roun...

Abstract

The invention is concerned with the battery group to prevent short-circuit for portable type DVD player, PDA or other electron equipment. It is to install the machinery switch at the front tip of the of the battery group discharge terminal that stays off when connecting with the electron equipment to keep it without short-circuit even connect with any other metal or conductor, which can reduce the damage of the battery group greatly. It is also to install circuit protection and thermal resistor to insure charging or discharging of the battery group safely.

Description

technical field [0001] The present invention relates to a battery pack that can prevent short circuit, that is, a battery pack that can prevent short circuit (Short) in the battery pack used in portable electronic devices such as portable DVD players (Portable DVD-Player) or PDAs. Background technique [0002] Today, portable electronic devices such as portable DVD players (Portable DVD-Player) that can play high-quality video and high-quality music for a long time, and handheld computers (PDAs) that can easily store and manage personal information have gradually become popular. [0003] In the above-mentioned portable electronic devices, a detachable, rechargeable and dischargeable battery pack (Battery Pack) is used. There are multiple battery cells (Cell) in the battery pack, and the battery cells can be charged through a charging device, or installed in a portable When the electronic device is on, the battery cells are discharged to provide the necessary power for the de...
