Because the storage battery has the advantages of high safety, low cost, mature production process and the like, the 110V and 220V lead-acid storage battery pack is still adopted as a backup power supply for power dispatching and control in the transformer substation in a quite long time in the future.
The storage batteries have service lives, the design life of the lead-acid storage batteries is generally 10-12 years, but after the lead-acid storage batteries provided in most transformer substations actually run for 3-5 years, the capacity of the lead-acid storage batteries is already lower than 80% of the nominal capacity (national standard requirement) and the lead-acid storage batteries need to be replaced. At present, the management strategy of the power grid to the storage battery causes the related maintenance personnel to face huge pressure, on one hand, the storage battery cannot be replaced easily without reaching the design service life, even if the whole approval process is quite long, the storage battery is likely to work with diseases during the approval, and the safety of the direct current system is seriously influenced, and the reliable operation of the power grid is also influenced. On the other hand, a large number of storage batteries are often idle for a long time and useless after being returned to operation, and the dangerous solid waste has great environmental and safety hazards.

A group of lead-acid storage batteries which are good in appearance and idle for a long time and are collected from a power supply company which is served by the company belong to a power supply station are detected to have the internal resistance which is increased, distilled water is reduced and the capacity is far lower than 80 percent. The operation maintenance personnel opens the battery cover and removes the safety helmet, fills each hole with distilled water (about 20-30 mL) with a syringe, and then holds the battery for more than half an hour to allow the sponge around the pole plate to fully absorb water. And in the second step, the storage battery is connected with the resistor for discharging (the bulb can be used for replacing the resistor without the resistor) until the voltage in the storage battery is reduced to 0V after all the electricity in the storage battery is discharged. And thirdly, repeatedly charging and discharging the storage battery to repair the storage battery. If the measured internal resistance of the storage battery is higher and the capacity is lower, the high-frequency pulse can be used for repairing by being assisted with high-current charging so as to improve the repairing effect of the battery. After the storage batteries are repaired in the mode, the capacity of the batch of storage batteries is basically recovered to more than half of that of the original storage batteries, a few storage batteries reach the use requirement of a transformer substation, return to the transformer substation station to continue to serve, and other storage batteries are installed in a gymnasium to continue to play a role.
The rest storage battery is connected into the detection and cascade utilization system (shown in figure 1), a monitoring platform of the system collects data such as single cell voltage, charge and discharge current, battery temperature and abnormal working conditions of the storage battery through various sensors (an internal resistance test module, a voltage detection module, a current detection module, a temperature detection module, a using process monitoring module and the like), and then the collected data is transmitted into an ARM controller through an RS232 communication port.
