Today, I would like to share with you some key points about using lead acid batteries. Hopefully, after reading this article, you will no longer panic about lead-acid batteries.

Battery Inspection and Maintenance

Battery maintenance is crucial. Whether it is manual operation and maintenance or automatic monitoring and management, the purpose is to timely discover abnormal faults of single batteries or equipment system failures that affect the battery charging and discharging performance, and take positive corrective measures to ensure stable and reliable operation of the power supply system.

Battery inspection and maintenance can be divided into enterprise daily management maintenance, quarterly maintenance and annual maintenance.

1, daily maintenance:

Ensure that the battery surface clean and dry.

② Always pay attention to the battery system ambient temperature and changes in the appearance of the battery;

③Check the battery online float charge voltage and battery pack float charge voltage (total terminal voltage), and compare with the panel display, and correct if necessary; ④Check the battery cabinet or battery room, and make sure that the battery is not damaged; ⑤Check the battery system ambient temperature and battery appearance changes.

④ Ensure that the battery cabinet or battery room is clean, ventilated or well lit.

2. Quarterly maintenance:

① Visual inspection as well as the cleanliness of the outer surface of the battery, the intact development of the shell and cover, the battery management exterior design with or without bulging and deformation and other changes, the battery enterprise with or without traces of overheating;

At the same test point of the battery system every quarter, record the ambient temperature of the battery system and the average temperature of the representative system.lithium ion battery VS lead acid battery When the temperature is lower or higher than 25 °C, the temperature control system should be adjusted, or the float charging voltage should be adjusted if no temperature control system is installed;.

③ Measure and record the total float charging voltage at the battery end and compare it with the display value of the panel ammeter. If there is any difference, find out the reason and correct it in time;

4 Measure and record the float charging voltage of each battery in the system, and the float charging voltage should fluctuate within a certain range under normal circumstances

⑤ Do recovery discharge test, discharge with dummy load or actual load, i.e. cut off the power supply and use the battery to supply power. If the capacity of a single battery is found to be low, equalize the charging. If the capacity cannot be recovered after equalization charging, please replace the low capacity battery.

3. Annual maintenance:

① Repeat all the work contents of the quarterly maintenance country;

② Check all the connection points between batteries and make sure the connection is tight and reliable;

③ Randomly select several batteries for internal resistance test.lithium battery vs lead acid Since there is no linear relationship between the internal resistance of the battery and its capacity, the internal resistance of the battery can not be directly used to indicate the exact capacity of the battery, but it can be used as an indicator signal of the battery's "health" status.

Second, several factors affecting battery life

(1) Depth of discharge.

The depth of discharge has a great impact on the cycle life of the battery. If the battery is frequently deep discharge, the cycle life will be shortened.

Because for the same rated capacity of the battery deep discharge means that we can often use high-current charging and discharging, in high-current discharging or often in an under-voltage state and can not be timely and effective re-charging, resulting in large sulfate particles, the plate active research material culture can not be fully developed and utilized, the long-term development of the actual teaching capacity of the battery will gradually begin to decrease, affecting the battery's normal management. Normal management work.

Since PV systems are less prone to overcharging, chronic power loss is the main cause of battery failure and shortened life of PV systems.

(2) Discharge rate.

Generally speaking, the capacity of 20 hours discharge rate is the rated capacity of the battery. If the discharge rate is lower than the specified number of hours, a higher than rated battery capacity can be obtained; if the discharge rate is higher than the specified number of hours, the discharged capacity is less than the rated capacity of the battery, and the discharge rate also affects the terminal voltage of the battery.

When the battery is discharged, the electrochemical reaction current is preferentially distributed on the surface closest to the main solution, resulting in the formation of lead sulfate on the surface of the electrode and clogging of the porous electrode. The problem is more prominent in high-current discharge, where the higher the discharge current, the smaller the capacity of the battery and the faster the terminal voltage drops, i.e., the discharge terminal voltage decreases with the increase of the discharge current.

However, on the other hand, the lower the discharge rate, the better. Some studies have shown that if the discharge rate is too small for a long time, the amount of lead sulfate molecules will increase significantly, thus generating stress, which will lead to bending of the pole plates and shedding of the active substances, and will also reduce the service life of the battery.

(3) The outside temperature is too high.

The rated environmental capacity of the battery refers to the value of the battery at 25 ℃, generally can be considered valve-regulated sealed lead-acid battery working temperature in the range of 20 ~ 30 ℃ management work development more lack of ideal.

When the battery temperature is too low, the capacity of the battery is reduced because the electrolyte can not react well with the active material of the plates at low temperature.
