The principles of the battery

The VGP-BPS8 VGP-BPS8A battery is a kind of energy conversion and storage devices. She is a physical or chemical reaction can be converted into electrical energy. Battery is a source of chemical energy, which consists of two different elements of the electrochemical activity of the composition of positive and negative electrodes, respectively, the two electrodes immersed in the media to provide conduction of the electrolyte, when it is connected to an external carrier, through its conversion to provide internal chemical energy can be. As an electrical storage device, when the two metals (usually a difference in the metal) are immersed in the electrolyte, they can be conductive, and the “plates” have a certain electromotive force between two. Size of the emf (or voltage) with the use of metal on different types of batteries for its electromotive force is also different.

Batteries chemical practices can be divided into two types: batteries. Made after the original battery can generate current, but the discharge is completed Jibei abandoned. Battery also known as secondary batteries before use should proceed to charge fees for use after discharge, the discharge can also be loaded after the re-use. Battery charging, the energy converted into chemical energy, the discharge of converting chemical energy into electricity. Dell Inspiron B120 battery  Dell Inspiron B130 battery

In cell chemical chemical energy directly into electricity by the battery is carried out within the spontaneous oxidation, reduction and other chemical reactions the result of the reaction was conducted in two electrodes. Negative active material of the more negative potential and an agent of the stable reduction in the composition of electrolytes, such as zinc, cadmium, lead active metals and hydrogen or hydrocarbons. Positive active material for a more positive potential on the composition of the electrolyte of a stable oxidizing agent as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or the air, halogens and their salts, oxygen-containing acid and its salts, etc.. Electrolyte is a good ionic conductivity material such as acids, alkalis, saline, organic or inorganic non-aqueous solutions, molten salts or solid electrolytes. When the external circuit disconnected, although there is potential difference between the two poles (open circuit voltage), but there is no current, stored in batteries are not converted to chemical energy into electrical energy. When the external circuit is closed, the two electrodes under the effect of potential difference there is current flowing through the external circuit. The same time, the battery inside the electrolyte are not due to free electrons, charge transfer must be accompanied by two poles of active material and electrolyte interface, the reactions of oxidation or reduction, and reagents and reaction products of mass transfer. Charge transfer in the electrolyte, but also by the migration of ions to complete. Thus, in the normal transfer of battery charge and the process of mass transfer is to ensure that the conditions necessary for normal production of electricity. When charging, the PB994A PP2182D battery inside the transmitter power and direction of mass transfer and discharge exactly the opposite reaction of the electrode must be reversible to ensure the opposite direction to the mass transfer and mass of normal electrical processes.

Therefore, the electrode reaction is reversible, a necessary condition for the batteries. Reaction of the Gibbs free energy (coke) F is the Faraday constant = 96,500 basis = 26.8 ampere-hour n the equivalent number of the cellular response. It is the reaction of the battery and the emf of the battery between the basic thermodynamic relations, but also calculate the energy conversion efficiency of cells of the basic thermodynamic equation. Indeed, when current flows through the electrodes, the electrode potential must deviate from the equilibrium thermodynamic potential of the electrode, a phenomenon known as polarization. Current density (electrode surface unit adopted by the current), more polarization worse. Polarization is caused by the energy loss of the battery of important reasons. Polarization for three reasons: ① from the cells caused by different parts of the polarization resistance is called Ohm polarization; ② electrode - interface layer caused by electrolyte charge transfer blocked the process of polarization is Name polarization activation; ③ electrode - electrolyte interface layer caused by the slow mass transfer of polarization is called concentration polarization. Reduce the method of polarization is to increase the reaction zone to the electrode, which reduces the current density, increasing reaction temperature and improve the catalytic activity of the electrode surface.

Seven points to keep in mind about car batteries maintenance

Car battery is important, its function is to provide an electric starter, the engine starting or operating at low speed for the ignition system of motor and other electrical equipment. High-speed operation when the engine when the generator enough, the VGP-BPS8 battery can store excess energy. Unfortunately, it is generally ignored by most people. I do not know the proper maintenance of batteries to keep it plenty of power, is an important part of vehicle maintenance. The following will introduce the conservation of car battery connected to knowledge and common sense, to help you better understands the use and maintenance of the battery to extend battery life.

Car battery car battery works the vast majority of lead acid batteries. In simple terms, it is a chemical energy into electrical energy capable of electrochemical devices. Lead acid battery in the positive and negative plates, bulkheads, shell, etc. electrolyte and wiring trailer hitch and the discharge of chemical reactions depend on the active positive plate (lead dioxide PbO2) and the negative active material (sponge of pure lead, Pb) in the electrolyte (sulfuric acid composition of H2SO4 and H2O water) and as a result. A standard 12V lead-acid VGP-BPS8B battery contains six modules, each of the power of electricity is about 2V (one for each power supply has a positive and negative column: column is entered the positive sign “+”, dark brown negative column when a “-” sign in pale gray).

Traditional batteries will occur in the electrolyte is in decline is because the frame plate door with traditional batteries lead alloy of antimony, antimony will pollute the negative plate of pure lead sponge, weakened after the battery is fully charged in a Counter electromotive force resulting from the decomposition of excess water, a large number of oxygen and hydrogen, respectively, escaped from the positive plate and negative, so the reduction electrolyte.

Without maintenance (maintenance free) batteries into the design principles and traditions of the battery on a coherent strategy, the use of thicker plate materials, important difference is that the plate is consistent with lead calcium alloy. In the electrolysis reaction, it can reduce the flow of excessive burden, reduce the rate of vaporization of liquid, thus reducing the loss of electrolyte, compared to prolong battery life.

Discharge and load

In the year (discharge) process dioxide very edge of lead (positive), the spongy lead (negative), and sulfuric acid electrolyte chemical reaction occurs to produce the discharge of lead sulfate (PbSO 4) and d water (H2O), positive and negative plate the difference between reduced. Because the battery voltage depends on different electrode materials and electrolyte concentration, so the reaction after discharge, the battery loses power. Charging process (charge) and discharge process to the contrary. Current in the generator under the action of sulphate of lead and water lead dioxide (positive), the spongy lead (negative) and sulfuric acid, plates, electrolyte concentration restored, the BATCL50L battery of energy.

Caution

1 to start the car every time startup should not exceed 3-5 seconds after starting interval of at least 10 seconds.

2 vehicles often short driving distance open-window open will result in a prolonged state of battery charge less to shorten the lifespan. On the highway driving at a constant rate of 20? 30 minutes, may give enough time to recharge the battery.

3, driving a day before leaving the car, check and ensure that all lights and other electrical appliances (such as radios, CD) has been closed. Because it may drain your battery.

4, if the battery runs out, to ask the fire (Jump-Start, also known as tie-lines) to begin immediately possible a constant speed (such as highway speed) drive at least 20? 30 minutes to fully charge the VGP-BPS11 battery.

5, in the full discharge of the battery case, ask the fire may be unable to help you start your car. In this case, you must use a dedicated battery charger for slow charging.

6, where cars are not long-term investment should first fully charge the car. At the same time every month, launched his car, operation at medium speed for about 20 minutes. Otherwise, place too long, it would be difficult to start.

7 to understand the life of the battery. Using more than 4 years, the recommended replacement.

Waste batteries repair is necessary

In recent years, people blindly focused on economic development at the expense of environmental protection to the environment have had an undeniable impact. While environmental issues and livelihoods in this regard would be of concern to all the specific details of our lives, on drums, for example, domestic civil society over 20 billion batteries a year, consumption of 6 billion, coupled with other types of cells, their number is very striking. Then we often use VGP-BPS8B battery electric vehicles, many people are not very expensive.

The advent of electric cars and pop will also be the standard with a large number of battery electric vehicles will be used. As the batteries of electric vehicles as a result inevitably bad, then the batteries of electric vehicles is necessary to lay broken VGP-BPS8 Mody? Is this not the case? Reuse of waste batteries will be repaired or if it is the resource for the environment would be very beneficial. Of course, this would undoubtedly promote the formation of piles of the waste industry to repair, and become industry leaders in the industry chain.

Batteries food waste is a high technology, why should we spend the effort to study the batteries Fix It? To return used batteries in the restoration work that we do not want to be as simple as that. Waste batteries need to have a professional repair equipment repair, and repair personnel professional, such a procedure is not telling the truth, like a VGP-BPS10 battery to change it. But from the standpoint of environment and resources is not the case. So how can we understand the specific terms used batteries repair industry? While speaking briefly about restoring the bar normal cell into repair mode.

The repair process of the battery in the operation of wastewater from the battery is over, so that positive and negative aspects of the machine are correct, the machine entered the charge state of repair, repair cycle 10AH is 5-8 hours, and 20Ah need 8-12 hours to get to the battery terminal voltage to 16V or more to stop the repair. Just for the initial discharge time allowed, are renewing a test discharge of the battery can. Then you will find restored before the discharge time much longer than the repair, indicating that the VGP-BPS11 battery has a positive effect repairs, as the ability to reach more than 70% of the plant can be operated.
