Problems solved by technology

However, the existing method of setting auxiliary structural parts usually takes up a large amount of internal space of the battery, so that only small-sized and low-capacity batteries can be used, which makes the integrated rechargeable battery more attractive than the primary battery. capacity advantage is not obvious

Embodiment 1

[0049] Taking the production of a cylindrical rechargeable battery with constant voltage output as an example, the structure and function of the rechargeable battery are further explained, and the method for realizing the large capacity of the rechargeable battery is also explained.

[0050] A rechargeable battery, which is cylindrical (its overall dimensions must meet the requirements of the R03 model size specification required by the "IEC60086-2:2011, MOD" standard), and its requirements are: battery diameter ≤ 10.5mm, battery height H ≤ 44.5mm, the battery has charging management functions; it has charging protection and discharge protection functions; the battery has constant voltage 1.50V±0.10V, continuous 300mA current output function. Such as figure 1 and figure 2 As shown, the rechargeable battery includes a rechargeable cell 1, a steel case 2, components 3 (including an integrated IC, a protection IC, a first resistor, a second resistor, a third resistor, a first c...

Embodiment 2

[0080] A kind of rechargeable battery, its structure is similar to the structure of the rechargeable battery in embodiment 1, and its difference is: the constant output voltage is 1.50V, and the specification of the third resistance R3 is 4K±1%, and the rechargeable battery corresponds to The maximum charging current is 156mA.

Abstract

The invention provides a rechargeable battery. The rechargeable battery comprises a rechargeable battery cell, a steel shell, a protection IC, an integrated IC, a first resistor, a second resistor, athird resistor, a first capacitor, a second capacitor, a third capacitor, an inductor, an LED lamp, a plastic part, a circular hard FR-4 substrate, a metal cap and a curing structural adhesive. Multiple functions of constant voltage output, charging management and protection and over-charging, over-discharging and over-current protection are integrated into one body. Compared with the prior art, by using the rechargeable battery, multifunctional integration of the battery can be realized, space occupation saving of battery accessory structural parts and a high capacity of the battery can be achieved.

Description

technical field [0001] The present invention relates to a rechargeable battery, in particular to a battery that integrates multiple functions such as constant voltage output, charging management and charging protection, and battery protection (including overcharge protection, overdischarge protection, and overcurrent protection), and simultaneously has High capacity rechargeable battery. Background technique [0002] Rechargeable batteries have the advantages of large capacity and recyclable use, and have been used more and more widely. For example, at present, lithium-ion rechargeable batteries have become the main power supply batteries for mobile phones, notebook computers, cameras, and portable mobile power sources, and in many traditional application fields of primary batteries such as remote controls, flashlights, toys, etc., rechargeable lithium-ion batteries are also gradually Replace the primary battery. [0003] But compared with primary battery, rechargeable bat...
