In the maintenance work, we summarize solutions for bulk batteries. On the one hand, according to the characteristics of the colloidal battery, the battery charging management software of the switching power supply is changed as follows:First, in order to shorten the time, the battery drum is avoided, and the unit floating conversion conditions are reset, and the original set current value is 10mA / Ah as a basic conversion condition to change the current to 20 mA / AH. That is, automatically converted to floating operation.
Second, the temperature sensor of the switching power supply is connected to the battery cabinet, so that the floating charge voltage of the switching power supply can be adjusted with the ambient temperature. Increased over temperature protection, the system automatically converts to floating operation when the temperature reaches 40 ¡ã C, and avoids the battery drums caused by sustained large current charging.
Third, in order to prevent the battery excess charge, shorten all charge protection time, change the all-charge protection time from 18 hours (all the setting of the protection time is to prevent battery thermal out of control, when all charging flow cannot be reduced to the setting When the floating conversion current value, the system enforces the system to float in the specified time).
Fourth, extend the timing basis and avoid overall frequency of large currents. Change the timing catenary period for 100 days to 180 days.
5. Cancel the freight function of the switching power supply to avoid booming of the battery caused by overcharge.
Through the modification of the battery charging parameters, it is mainly to avoid the switching power supply to overcharge the colloidal battery in the case of satisfying the battery is fully charged.
On the other hand, in order to prevent the quality of the safety valve, the exhaust gas is not smooth, you should pay attention to the inspection of the safety valve in the daily inspection, while requiring battery manufacturers to further improve the quality inspection and manufacturing process of the safety valve to ensure the safety valve After reaching the valve value, you can open the valve and exhaust.
Through the above treatment, after a period of observation, the colloidal battery did not appear in the housing bulging phenomenon, and the operation was in normal state.
In summary, in the high temperature environment in the south, according to the characteristics of the colloidal battery, in the case of ensuring that the battery is fully charged, it is reasonable to fill the floating-limit current value and all charge time, avoiding the battery overchard. Battery housing is onhibiting problems, while doing a good job of over temperature protection of the battery and strengthening the inspection of the safety valve, it is found to be replaced in time to improve the efficiency of the colloidal battery and life. In this way, the strength of the colloidal battery has the advantage of reducing lead and acid contamination environment Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
