Abstract
The utility model discloses a hybrid power source that zinc -silver reserve cell and ultracapacitor system constitute, this hybrid power source is by the parallelly connected hybrid power source unit of constituteing of suitable capacity ultracapacitor system C and zinc -silver reserve cell G. The utility model is suitable for a zinc -silver reserve cell system, at low temperature environment, big current pulse under three kinds of short condition of battery activation time, can effectively improve zinc -silver reserve cell electrical property output capability, improves zinc -silver reserve cell specific power.
Description
Technical field
The utility model relates to a kind of AC-battery power source, belongs to zinc-silver reserve battery field.
Background technology
Zinc-silver reserve battery is the chemical power source that a kind of specific energy and specific power are high, has that big current discharges for a long time, the advantage such as long storage life and high security.Stock the employing of formula zinc-silver oxide cell and electrolyte and cell are separated the mode deposited, during use, electrolyte injects battery pile fast, by electrochemical reaction, provides electric energy.Its advantage is that specific energy is high, specific power large, discharge voltage precision is high, safety, reliability are high, but under the short three kinds of situation actings in conjunction of low temperature environment, heavy current pulse and activationary time, zinc-silver reserve battery electrical property fan-out capability is poor, voltage delay phenomenon is comparatively obvious, and the use in armament systems is severely limited.
Ultracapacitor: also claim electrochemical capacitor, had both had the high power density as electrostatic condenser and long circulation life, had again the high-energy-density as battery, and this makes ultracapacitor combine the advantage of two kinds of energy storage devices.Its advantage is that power density is large, charge/discharge rates is fast, energy storage efficiency is high, has extended cycle life; But because its energy density is on the low side, be also not suitable for the application of jumbo power energy storage.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of AC-battery power source, under this AC-battery power source can solve low temperature environment, heavy current pulse, short three kinds of situations of battery activated time, the problem of zinc-silver reserve battery electrical property fan-out capability difference, avoid the phenomenon of voltage delay, improve zinc-silver reserve battery specific power.
Zinc-silver reserve battery is in low temperature environment, heavy current pulse, short three kinds of situations of battery activated time, and the reason of electrical property fan-out capability difference is: a) because battery time is short, loads the initial stage, and electrode is not soaked thoroughly by electrolyte completely, and polarization resistance increases; B), during heavy current pulse, concentration polarization internal resistance increases; C) under low temperature environment, electrolyte viscosity increases, and mobility reduces, and conductivity declines.
Have found the reason of problem, the utility model takes following technical scheme to tackle: by zinc-silver reserve battery both positive and negative polarity extraction place upper ultracapacitor both positive and negative polarity in parallel respectively.Ultracapacitor voltage is less than or equal to reserve cell open circuit voltage, and electricity is charged to proper states.
Adopt ultracapacitor and zinc-silver reserve battery parallel operation, under solving low temperature environment, heavy current pulse, short three kinds of situations of battery activated time, the problem of zinc-silver reserve battery electrical property fan-out capability difference, avoids the phenomenon of voltage delay, improves zinc-silver reserve battery specific power.
The utility model utilizes that ultracapacitor power density is large, charge/discharge rates is fast, energy storage efficiency advantages of higher, compose in parallel AC-battery power source with zinc-silver reserve battery and externally export electric energy, improve that zinc-silver reserve battery electrical property fan-out capability in three kinds of situations is poor, voltage delay phenomenon problem.
Compared with prior art, successful, connection are simply, cost is low, reliability is high for the utility model.

Embodiment
As shown in Figure 2, the concrete building form of AC-battery power source of the present utility model is: electrode zinc-silver reserve cell G is made up of positive electrode, barrier film, negative electrode.Ultracapacitor C is made up of carbon positive pole, barrier film, Carbon anode, electrolyte, ultracapacitor C both positive and negative polarity in extraction place of zinc-silver reserve battery G both positive and negative polarity respectively parallel connection.Wherein ultracapacitor C membrane module monomer series-connectedly to form by 15.
Condenser voltage is less than or equal to zinc-silver reserve battery open circuit voltage, and electricity is charged to proper states.
At 15 DEG C, zinc-silver reserve battery is in parallel with ultracapacitor immediately after activating, and forms AC-battery power source, discharge after 30s, compared with traditional zinc-silver reserve battery, load the initial stage, big current (3 multiplying power) pulse discharging voltage raises 1.72V(and on average rises 6.2%), see Fig. 3; Process of pulse discharge, early stage, voltage rise 3.46V(on average rose 13.5%), middle and later periods voltage rise 2.14V ~ 2.84V(on average rises 9.5%); Constant current (0.3 multiplying power) is discharged, and voltage rise 0.68V(on average rises 3.0%), see Fig. 4 and Fig. 5.
