Embodiment Construction

[0039] In principle, a supercapacitor belongs to an electric double-layer capacitor (Double-Layer Capacitor). Its principle is to use the electric double-layer (Electric Double-Layer) generated by the electrode / electrolyte interface to store charges. The capacitance of layer capacitance depends on the surface area of ​​the electrode. Increasing the surface area of ​​the electrode can increase energy storage, so the electrode of porous material can increase the capacitance, and its internal resistance (Equivalent Series Resistance, ESR) is the resistivity of the element between the two electrodes. The sum of the total, selecting electrodes and electrolytes with higher conductivity can obtain lower internal resistance, thereby increasing power density and energy density.

[0040] see figure 1 As shown, it is the block diagram of the circuit of the present invention, as shown in the figure: the electric energy storage device of the present invention is composed of a battery pack ...

Abstract

The electric energy storage apparatus is composed of the battery group, which contains at least are batteries, and the super caparcitor, which is parallel connected with the battery group. By recharging to the super capacitor with the battery group to make the super capacitor to output the great current in instance, the super capacitor absorbs the great cuttent in instance of the feedback. Thus the apparatus can prevent the instant great current form destroying the inner structure.

Description

technical field [0001] The invention relates to an electric energy storage device, in particular to an electric energy storage device in which a battery pack is connected in parallel with a supercapacitor. Background technique [0002] With the increasing popularity of mobile phones, not only office workers with financial means use mobile phones in large numbers in Taiwan, but even students have already entered the era of mobile phones. However, with the increasing dependence on mobile phones, people's requirements for mobile phone functions are also getting higher and higher. [0003] The popular GSM mobile phone on the market today, because its wireless communication system uses signal compression, so there will be a surge load during a call, that is, the so-called pulse current. This instantaneous high current output will cause great damage to the battery. , often leads to a decrease in battery discharge capacity and reduced lifespan. [0004] However, today's batteries...
