Before the entire group relative voltage monitoring mode, the cell voltage monitoring is a big step forward, but in the long-running process of the battery capacity fading and even failure monitoring, voltage reflects the problem is very limited: 100Ah batteries and decays to the differences in the 10Ah battery float voltage is difficult to distinguish. Therefore, the need to explore the failure mode from the battery to solve the problem of the battery monitor. Second, the VRLA battery failure mode for VRLA batteries, the usual performance deterioration mechanisms are the following situations: 1, heat accumulation opening lead-acid battery charging, in addition to the active substance regeneration outside, There sulfuric acid electrolyte in the electrolysis of water to generate hydrogen and oxygen gradually. When the gas from the battery cover vent to the atmosphere, the decomposition of water per 18 grams 11.7 kcal of heat. For VRLA batteries, oxygen flows internally generated during charging negative oxygen at the negative plate active material spongy lead oxide, and low effective supplement the loss of water electrolysis. Since the oxygen cycle suppresses hydrogen evolution and oxygen involved in the reaction and the generated water. Although this eliminates the problem of explosive exhaust gas mixture, but this sealed reduces the thermal diffusion of an important way, but only by the battery shell wall heat transfer as the only way to heat. Therefore, the thermal runaway VRLA battery issue has become a frequently encountered problem. VRLA batteries depends on the power of the shell wall heat conduction to heat, good ventilation and low temperature when the battery is installed is very important condition. To further reduce the risk of thermal runaway, float voltage is usually depending on different producers and different temperature dependent. Manufacturers are generally given the float voltage and battery temperature compensation coefficient. 2, issue sulfated VRLA battery is more likely than the opening ceremony was the negative plate sulfation. This is because: 1) the lower the negative electrode plate due to the circulation of oxygen potential; 2) the acid stratification in the electrolyte pooled at the bottom of the battery acid is formed, in which the no-flow, non-circulating electrolyte system is difficult to avoid a. Both are likely to produce a certain amount of residual sulfate under floating conditions, and then converted into a permanent form of sulphate. Thus, when deactivating the acceleration electrode plate, the 安时容 available discharge amount is reduced. As the negative electrode plate temperature increases, this situation will worsen. As a result of the reaction of oxygen cycle, the negative plate surface is oxidized, a considerable amount of heat released (Hills batteries) a good safety performance: No electrolyte leakage under normal use, no cell expansion and rupture. 2, the discharge performance: stable discharge voltage, discharge platform gently. 3, good resistance to shock: fully charged battery completely fixed to 4mm amplitude, frequency 16.7Hz vibration 1 hour, no leakage, no cell expansion and cracking, open circuit voltage is normal. 4, good impact resistance: the battery is fully charged state natural height from 20cm down to 1cm thick hardwood board 3 times. No leakage, no cell expansion and cracking, open circuit voltage is normal. 1.
