【導讀】它的工作原理就是把化學能轉(zhuǎn)化為電能。它用填滿海綿狀的鉛板作負極，填滿二氧化鉛的鉛板作正極，并用22～28％的稀硫酸作電解質(zhì)。為了提高蓄電池的使用壽命，保證其可靠運行，需要經(jīng)常對蓄。電池參數(shù)進行嚴格測量，以確保蓄電池組處于最佳的工作狀況。量精度，對蓄電池參數(shù)進行自動測量顯得尤為重要。在多個單體電池串聯(lián)組成的。及時找出損壞的和性能顯著降低的電池，可以提高整個電池系統(tǒng)。由于受環(huán)境限制，要求系統(tǒng)簡小、實用，可以每個電池配備。池、干電荷蓄電池和免維護蓄電池。鉛酸蓄電池一般是由正負極板、隔板、殼體、鎳鎘電池是前幾年使用最為普遍的充電電池。池得到了更為普遍的使用。鎳氫電池的容量比鎳鎘電池高－2倍，且具有不污染。但是鋰電池成本高而且充電器要求也是最高的。很容易損壞電池，甚至產(chǎn)生電池爆炸。作為后備電源,蓄電池是確保設備正常運行的最后一道生命。間的推移,電池使用年限的增加,由電池引起的中斷事故將防不勝防。

　　

【正文】 ar as possible to ensure sufficient battery power to prevent irreversible sulfation. 2, the frequency of the choice of charging Battery life cycle of the depth of the impact of large changes in the basic exponentially. This is because the positive active material for Pb02, the bination of fastness is not high, discharge time and charge into PbS04 into PbO2, and PbSO4 size larger than PbO2 the volume ratio of about 2: 1 . Therefore, the positive plate, the actives will be repeated contraction expansion to the connection between the particles gradually fell off, so that the loss of battery discharge characteristics actives bee anode mud so that the battery performance until the end of life. Deeper depth of discharge, the greater the amount of expansion contraction of activity in the greater destruction of binding force, the shorter life expectancy。 the other hand is the longer cycle life. In theory the battery should be avoided as far as possible the use of deep discharge, shall be sufficient ground shallow place, provided there is a special match with the matching charger. However, in actual use, due to battery performance and battery by the charger itself and the discrete charge and the charge used to the speed of the impact of higher than the voltage charger, charging more or less existed. In particular, the majority charge at night, generally in 610 hours, with an average of about eight hours, if shallow discharge, the charge will soon reach the end of the efficiency of this low charge will result in chargeoff. Have relatively long charging time, coupled with frequent charging, battery life would be a greater impact because of charge. According to the charging requirements of the best on the actual situation, it is necessary to refer to normal operating frequency, length, the storage battery factory provided, as well as supporting the development of charger performance parameters such as frequency of charge. By the vast majority of users, in order to discharge the battery depth of 50% 70% of an electric charge the best, so that battery life for the best results. Actual use can be converted to mileage riding in an electric charge when necessary. 3, the effects of temperature on the charge Season run at a high temperature battery, the main problem of the existence of chargeoff. Battery when the temperature increased, the increase in the activity of active substances, positive potential of a decline in oxygen evolution, oxygen evolution anode potential also decreased negative decrease , so charging rechargeable fast response time, charge current, and charging needs lower the charge voltage. In order to prevent excessive charge voltage, battery temperature should be kept as low as possible to ensure good heat dissipation, to prevent charging in the hot sun after exposure and should be far away from the heat source. Batteries at low temperatures, the lower the activity of the active substance, which dissolved electrode bees difficult, after the charge consumed when it is difficult to be added Pb, the charge current significant drop in positive plate at 20 ℃ in the charge acceptance of current only 70% at room temperature, and the negative effects of charging by the expansion agent, the ability to accept a lower charge temperature 20 ℃ to accept the charge current of only 40% of room temperature. Therefore, the main charge under the conditions of lowtemperature charge acceptance of the existence of poor, the problem of insufficient charge, request for increasing the charge voltage and charge time extended. Should be to improve the low temperature performance of the main negative start. Lowtemperature thermal insulation used antifreeze measures to be taken, in particular charge should be placed on a warm environment, conducive to guarantee sufficient power to prevent the emergence of irreversible sulfate, extended battery life. Storage and use of batteries during charging can be activated periodically, the socalled balance charge, this battery to prevent irreversible sulfation very good for a very good battery life, it is worth advocating. Third, note the use of batteries 1, to prevent over discharge Battery voltage after the termination of discharge to continue to discharge as the dischargeoff. Will have serious damage to the battery discharge, the electrical performance of the battery cycle life and severely disadvantaged. Battery discharge voltage to the termination of the internal resistance of a larger concentration of electrolyte is very thin, especially the plate hole and the surface almost at neutral, had fever resistance discharge orientation, volume expansion, a larger discharge current, the apparent heat or even develop fever deformation , then sulfuric acid concentration of lead in particular, and the existence of branches increased the possibility of shortcircuit crystal Moreover at this time will be the crystallization of lead sulfate to form bigger particles, namely, the irreversible formation of sulfate, and will further increase the resistance , the charge to restore the capacity of the poor, and even beyond repair. Should have been used to prevent battery discharge, the undervoltage protection is a very effective measure. In addition, electric vehicles as a result of undervoltage protection is controlled by the controller, but the controller other than the voltage of some equipment such as tables, lights and other electrical power consumption is directly powered by the battery, the power supply in general is not controller, the electric lock switch In the event of power began to close. While the current small, but if the discharge time 12 weeks will discharge occurred. Therefore, the lock may not be a long time, do not have to be switched off immediately. 2, t
