【正文】 counted for 35%, in recent years the data interface rapidly, the ratio has risen to 7%. Two sets of data to show that the problem is more serious battery, the battery power supply of security and reliability have a serious threat, investigate its reason, mainly in the following nine aspects: battery design process quality The battery design process exists plate technology design, material design, oxygen posite design, the pressure set A prehensive plan defect, make a battery performance and life have been affected, main performance for battery failure, early leakage water loss, deformation cracks, etc. For simple ascending battery capacity, will the battery plate thin, and increase the number plate, makes the same volume of the casing electrolyte reaction area greatly increased, capacity improve soon, but because thin plate, plate easily corrosion, softening battery, service life and therefore greatly shorten, easy to produce the early failure problems. Because of the low pressure setting, charge once to a certain pressure, control valves will be open Rev., gas is through the valve were leaked, cause the battery fluid loss (usually in a hole or a column valve will find a slightly damp near the liquid), this kind of battery also easy to produce the early failure, valve pressure design and material also has a direct relationship between the shell. Due to shell material, oxygen posite efficiency, valve design pressure, and other prehensive technology lack, some batteries in the process of charging and discharging pool, easy to produce the shell deformation, beat even crack. the influence of the operation environment Running environment is the main room temperature on battery life influence is bigger, in 25 ℃ environment conditions , the environmental average temperature increase every 10 ℃ , battery life is reduced by half. Northwest temperature changes greatly (a 30 ℃ a + 55 ~ C), the substation telemunication room less equipped with air conditioner, thermal performance is poor, temperature on battery life form directly influence. operation mode and installation method Battery packs are generally more battery series into a group, two groups of parallel operation. Site often Found in the internal battery, article connection (board) corner of battery performance generally have slightly worse, the main reason is the article connection too long (other connection is the article 5 a l0 times) and the materials of the contact resistance caused too large, lead to the connection of pressure drop article is too big, in the process of charging and discharging, will seriously affect peripheral battery charging and discharging effect, this kind of problem should be avoided. the quality of power supply and load design problem The tele room is located in remote ge
