So-called super capacitor is meant the application double-decker, and electrode is formed with particular process sequence, for example forms the honeycomb tissue, in order to improve the surface area of Unit Weight; Its capacitance often reaches one or several farads value, far surpasses the capacitor volume that adopts in the general electronics electrophoresis, so be also referred to as farad capacitor device or double-deck ultra-high capacity device.Its energy stored can it is generally acknowledged that the internal driving of super capacitor is very low in abrupt release, if directly in parallel with battery, will produce great charging current, causes battery or electric capacity to suffer damage even explodes.
General capacitor, electrolytic condenser for example, can be considered an ideal capacitor connect respectively resistance and parallel resistance, if because of the electric current that capacitor moment passes through excessive, the heat that the Yin Jiaoer effect is produced makes that electrolyte is heated in the capacitor, cause the parallel resistance value to descend, thereby material degradation and exploding.
In fact, can know that by embodiments of the invention ultracapacitor is general capacitor because of structure is different from, and approach lithium battery, so its internal resistance is adjusted with the variation of service condition, can not produce the result of general expected battery explosion to the battery system of suitable collocation.According to a design criterion, battery and super capacitor can be directly in parallel, do not need converter or current-limiting mechanism; The internal driving of super capacitor can change to some extent along with the discharge of super capacitor, its on circuit as shown in Figure 4, when the voltage of super capacitor is filled, internal resistance is R1 no better than, but after super capacitor begins discharge, the effect of each resistance R 2 to R5 can display among Fig. 4, and the internal resistance of super capacitor will be risen gradually.
With respect to super capacitor, the internal resistance RB of battery is almost fixing during discharge, can illustrate as the model of Fig. 5 on circuit.
This design criterion shows, as shown in Figure 4, R1 represent super capacitor 4 in the internal resistance of filling when full, needs only the internal resistance RB of R1 less than battery 2, consults Fig. 5, and then super capacitor 4 can be directly in parallel with battery 2, do not need converter or current-limiting mechanism.At the initial stage of discharge, most discharging current can be supplied by super capacitor, but after discharge a period of time, total internal resistance meeting of super capacitor is risen, make its discharging current diminish, when total internal resistance of super capacitor rose to internal resistance RB above battery, battery can charge to super capacitor automatically.
Direct in parallel for super capacitor and battery, the method that the present invention proposes be,, earlier super capacitor charged with before battery is in parallel at super capacitor, and super capacitor voltage is risen near cell voltage, and be in parallel with battery more afterwards.Battery can be one, also can be several compositions of series connection, specifically decides on operating voltage.Because the voltage of super capacitor and cell voltage are very approaching, battery can be very not big to the charging current of super capacitor, do not need external converter or current-limiting resistance between the two.In other words, moment in parallel with super capacitor can not produce after the very high currents as long as elder generation, makes battery to the super capacitor charging, and current relationship between the two promptly can reach a balance, does not need between to add known other circuit such as converter.
As long as the internal resistance RB to super capacitor and battery does suitable selection, make R1 less than RB, then instantaneous large-current can be supplied by super capacitor automatically, when the stored electric energy of super capacitor has been put soon, battery can charge to super capacitor automatically, whole system can be done the output of instantaneous large-current, and battery can discharge stored electric energy fully.
A preferred embodiment of apparatus for storing electrical energy of the present invention, as shown in Figure 6.When apparatus for storing electrical energy was applied to as chargeable electric tools such as Portable electric drills, its load state needed the big electric current of pulsed more.When load needs big electric current, come offered load a period of time by the super capacitor in the apparatus for storing electrical energy 14,2 of serondary lithium batteries are used for store electrical energy, when super capacitor 4 drains most of electric energy, simultaneously by 4 chargings of 2 pairs of super capacitors of serondary lithium battery, supply next wave impulse big electric current with store electrical energy, do not do big electric current because of lithium battery 2 and spark, so can increase the useful life of lithium battery.
Higher because of the energy density of lithium battery, so the nickel-cadmium cell that the lithium battery weight ratio is commonly used in the apparatus for storing electrical energy is light, therefore the overall power density of apparatus for storing electrical energy of the present invention (power that Unit Weight is exported down) will improve many.
Those skilled in the art all know in the industry, and the battery in this apparatus for storing electrical energy can comprise various forms of secondary cells, and generally can not TunePower.
Consider the protection of battery, also can comprise a battery protection controlling organization 10 and a bidirectional current mains switch 11 of connecting with this lithium battery 2 in another preferred embodiment of the present invention, these mechanisms can protect lithium battery 2 can not overcharged.When apparatus for storing electrical energy 1 in when charging, if there have the voltage of any lithium battery 2 to surpass to be specified, controlling organization 10 just can be sent signal to bidirectional current mains switch 1, and the path of charging current is cut off, and lithium battery 2 is no longer charged; Moreover, these devices also can protect lithium battery 2 can not be subjected to over-discharge can, when apparatus for storing electrical energy in when discharge, if have the voltage of any lithium battery 2 low rated voltage, controlling organization 10 can be sent signal to bidirectional current mains switch 11, the path of discharging current is cut off, lithium battery 2 is no longer discharged; And these mechanisms also can protect lithium battery can not operate under big discharging current, work as apparatus for storing electrical energy; when discharge, specified if discharging current surpasses, controlling organization 10 can be sent signal to bidirectional current mains switch 11; the path of discharging current is cut off, lithium battery is no longer discharged.
Consider the protection of super capacitor 4, preferred embodiment of the present invention also comprises a Zener diode 9 and self-healing fuse 12, its protection super capacitor 4 can not operated under over-voltage condition: if when the voltage of super capacitor 4 surpasses the rated voltage of Zener diode 9, Zener diode 9 will conducting, make the electric current Zener diode 9 of all flowing through, can under over-voltage condition, not operate to guarantee super capacitor 4; And; its protection apparatus for storing electrical energy 1 can not operated under overcurrent situations: self-healing fuse 12 is a kind of resistance of positive temperature coefficient; when the electric current of apparatus for storing electrical energy 1 is too big; the temperature of self-healing fuse 12 will raise; resistance becomes very big and failure of current, can guarantee that so apparatus for storing electrical energy can not operate under overcurrent and excess temperature situation.
