teristic parameters are mainly embodied in the voltage, resistance and capacity, the conventional detection method mainly measuring voltage, observe the shell signs, check the bolt tightness etc. So that only some representations to the parameter, and cannot master39。 s important! Parameters such as resistance, capacity, etc. charger, discharge management system is not perfect Recharging problems mainly involves to charge cycle, all are charging pressure, flow, all are charging filling time, All filling conversion control, float temperature pensation of detailed regulations. Some maintenance personnel to improve battery charging efficiency, improved charging voltage, and increase the charging current, leading to increased pressure, then bined low efficiency, the battery to dehydrate, are plate bar corrosion. With this several years of battery management know deeply, related problems reduce gradually, but for this problem or must cause enough attention to main pay attention to the following three points: one is the charge can39。 t charge high pressure, even with are charging, voltage must also be restricted in V scope (the new battery should be controlled in 23 V)。 2 it is charging electric current cannot too much, it will speed up plates corrosion, cause plate softening, restrain oxygen posite efficiency。 3 it is charging process must be temperature pensation, pensation coefficients for a 3 mV / ℃ 2 mV / ~ C one. 2. Testing and maintenance program replacement has serious degradation the battery packs, strengthen the selection of the battery To find Bi can have depth degradation and a serious threat to the security of the battery power supply system Groups should be early change, and strengthen the battery technology selection. Process quality problem is the focus of the selection consider battery, the battery can be based on standard, battery makers to raise specific technical requirements, suc h as of the materials, valve pressure., plate thickness, quantity, voltage, resistance Sui, balanced equilibrium characteristics, oxygen posite efficiency, water loss rate, for through the acceptance test can detect project, must conduct test on these work can be further ensure the reliability of the battery for longterm use. Vrla batteries for production technology is strict, at present domestic battery life Manufacturers in the more than 300, all sorts of technology of handicraft is various, the proposal is in before purchase, the battery rigorous screening, as far as possible choice plete production equipment, strong technical force, service facilities, perfect brand enterprise. , strengthen early battery test, improve battery support ability of put into operation At the beginning of the storage battery check is a very important testing link, the battery。
