subject: Theory of battery charge time [print this page] Theory of battery charge time.The theory of the battery charge time: battery charger power divided by the output current. For example: a battery 800MAH battery for example, dell inspiron mini 9 Battery the charger output current 500MA then charging time is equivalent to 800MAH/500MA = 1.6 hours, when the charger shows charging is completed, preferably about half an hour or so should be given to the battery the complement of power-up time.
From the positive plate group, the negative electrode plate group, composed of electrolyte and containers. Charge after the positive plate is the brown lead dioxide (PbO2), the negative plate is a gray velvet-like Lead (Pb), when the bipolar plate placed in a concentration of 27% ~ 37% of the sulfuric acid (H2SO4) aqueous solution, the very plates of lead and sulfuric acid chemical reaction, divalent lead ions (Pb2 +) transferred to the electrolyte, in the negative board leaving two electronic (2e-). Positive and negative charge due to gravity, lead positive ions gathered around the negative plate, while the positive plate in the electrolyte under the action of water molecules in a small amount of lead dioxide (PbO2) infiltration of the electrolyte, in which two oxygen ions and water prices compounded , so that lead dioxide molecules which can be dissociation of an unstable substance - ?lead hydroxide Pb (OH4?). Lead hydroxide, lead prices by 4 positive ions (Pb4 +), and 4 hydroxyl ?4 (OH) -? composition. 4 price of lead ions (Pb4 +) remain in the positive plate, so that positively charged anode plate. As the negative plate with a negative charge, which arose between the bipolar plate a certain potential difference, which is the battery EMF. When connected to the external circuit, current flows from the positive anode. In the discharge process, the negative e-board continuous flow positive by the external circuit board, this time in the electrolyte sulfuric acid molecules within the ionization due to positive ions into the hydrogen (H +) and sulfate anion dell inspiron mini 9 Battery (SO42-), in the ion under the action of electric field strength , both positive and negative ions respectively to move sulfate anion to reach the negative plate of lead, after the positive ions together to form lead sulfate (PbSO4). In the cathode board, since the digital from the external circuit flows, while the price of lead and 4 positive ions (Pb4 +) Synthesis of 2 price of lead ions (Pb2 +), and immediately with the positive plate in the vicinity of the sulfate anion attached together to form lead sulfate on the cathode.
As the batteries discharge, positive and negative plates are subject to sulfide, while the sulfuric acid electrolyte gradually reduced, while the moisture increased, leading to decline in the proportion of the electrolyte in actual use, the proportion of the electrolyte can be measured to determine the battery's discharge degree. In normal use, the lead-acid batteries discharge should not be excessive, otherwise the will and the active substance mixed with a small lead sulfate crystals to form a larger body, which not only increase the resistance of the plate, but also in charge when it is difficult to make it again restore, build a direct impact on the capacity and life of the pool. Charging lead-acid batteries is the reverse process of discharge.
Lead crystal battery.Application of lead-crystal battery is proprietary technology, using high-conductivity silicate electrolyte is the traditional lead-acid battery electrolyte complex variant, non-acid mist formation process is finalized within the innovation process. Processes are first of these technologies at home and abroad, the product in the production, use and waste pollution problem does not exist, more in line with environmental protection requirements, due to lead-crystal battery to replace the sulfuric acid solution with silicate as electrolyte, thereby overcoming the lead-acid batteries life is short, not high current charging and discharging of a series of shortcomings, more in line with the essential conditions of power batteries, lead crystal battery will also power the battery on the field a tremendous boost.
Solar.To the energy of sunlight into electrical energy. The day when the light irradiation, resulting in terminal voltage, to be current, for satellite, spacecraft in the solar cell is a semiconductor made of (commonly used silicon photovoltaic cells). Sunlight solar surface, the semiconductor PN junction on both sides of the formation of potential difference. Its efficiency was 10% more than the typical output power is 5 ~ 10 milliwatts per square centimeter (junction area).Battery temperature.Then two kinds of metal into a closed circuit, and the two joints at different temperatures to maintain generate electromotive force, that is, temperature difference electromotive force, which is called the Seebeck effect (see the thermoelectric phenomena), such a device called a thermocouple or a thermocouple. Metal thermocouple electromotive force generated by a smaller Dell inspiron mini 9 Battery temperature difference, commonly used to measure the temperature difference. However, the thermocouple when the series into a thermopile, also can be used as a small power supply, which is called the battery temperature. Made of semiconductor materials with temperature batteries, thermoelectric effect stronger.
