1. Battery leakage, a common leakage: First, the upper cover and the bottom tank are sealed or caused by collision, sealing glue cracking, and the second is the safety valve iodary acid leakage; the three terminals are iodal acid leakage; four other parts Decamine leakage. Check and processing method: first make an appearance check, find the queous leakage site.

Once the cover is removed to view the safety valve with an oxygen-proof leakage traces, then open the safety valve to check the inside of the battery with a flowless electrolyte. After completing the above work, if an abnormality was not found, it was observed that the battery had no bubbles appeared and appeared, and there was a bubble, and there was a bubble. Finally, during the charging process, it is observed that there is no flowable electrolyte, if there is an explanation is the cause of the production.

During the charging process, there is a flowing electrolyte to take it. 2. The deformation failure phenomenon is not burst, often has a process.

The battery enters high voltage charging regions around 80% of the charge to capacity. At this time, the oxygen is precipitated in the positive electrode, and the oxygen passes through the holes in the partition. Oxygen resurrection reaction on the negative plate: 2Pb + O2 = 2PBO + H2O + QPBO + H2SO4 = PBSO4 + H2O + Q reacts heat, when the charging capacity reaches 90%, the rate of oxygen increases, and the negative electrode begins.

Hydrogen. The new increase in a large amount of gas is that the battery internal pressure exceeds the valve pressure, the safety valve is opened, and the gas escapes, and finally it is lost. With the addition of the battery cycle, the water storage is gradually reduced, and the battery is as follows: (1) The oxygen passage becomes smooth, and the oxygen appearing in the positive electrode is easy to reach the negative electrode through the channel.

(2) The heat capacity is reduced, and the maximum heat storage is water. After the water loss, the battery heat capacity is greatly reduced, and the heat that occurs makes the battery temperature rise very quickly. (3) Due to the contraction of ultrafine glass fiber separators in the battery after lossless, it is deteriorated with the adhesion of the positive and negative plate, and the internal resistance is large, and the charge and discharge process is increased.

After the above process, the heat inside the battery can only be dissipated by the battery tank. If the heat dissipation is less than the heat generation, the temperature rise is increased, so that the electric storage gas is lowered, the quantity is increased, and the positive electrode is passed through the channel, and the negative surface is reacted, and a large amount of heat is rapidly increased. Forming a malignant cycle causes thermal out of control, deformation.

Fault inspection and processing a set of batteries (3) simultaneously deformed, first voltage check. If the voltage is substantially normal. It should also be measured whether a single voltage determination is shorted, and there is no short circuit, the deformation is caused by heat-failing.

Attention should be heard the charging parameters of the charger. The voltage is high in V or the high-voltage or trickle conversion current is low, and the charger is required to replace the charger. 3.

Short-circuit fault phenomenon of battery voltage drop 2 integer times fault checks and processing multimeter detects battery single voltage, short circuit battery scrap 4. The discontinuation of the fault phenomenon is charged, and the inspection and processing of the electricity failure can be used to detect the battery voltage. If it is 0, there is no spark of fire, and the charge is not advanced.

Broken battery scrap 5. The inverse fault phenomenon detects that the battery voltage detection of the battery voltage and processes the battery to discharge the battery to 0 volts, and then fully charge the battery 6 with maintenance charger. Inverse sulfate 1, fault phenomenon plate sulfate is a common fault of batteries, and many battery failures are also due to this failure.

Manifestasi penting dari pelat sulfat adalah: tegangan segera dinaikkan, dan suhunya cepat, suhunya cepat, dan kapasitasnya kecil saat pelepasannya rendah. 2. The test and handling of the polar can be attributed as follows: (1) The storage time is too long, the self-discharge rate is high, and the charging is not performed.

(2) Isi ulang tepat waktu setelah pengosongan. (3) Lama berada di bawah status muatan. (4) Pelepasan daya berlebih.

(5) Konsentrasi elektrolit kering atau tambahan. When the battery is inversely reversible sulfate, it should be repaired according to the degree of weight. The salinity is lighter, and the average activation charging (ie, balanced charging) can return to normal.

The specific method is as follows: Constant voltage limit charging: The first stage 0.18C2A charges to 2.7V / single charging 12-24 hours.

The first stage of constant current: 0.18C2A is charged to 2.4V / single, the second stage: 0.

05c2a charge 5-12 hours. Salterization, it is necessary to charge the hydraulic charge and discharge, to return to normal. The specific method is: first adding the battery to the low water or density of 1.

05 g / cm3 dilute sulfuric acid to the rich liquid, and then charge the current of 0.05-0.018c2a for about 20 hours, and exhaust flow fluid, and then make capacity test.

Repeat the above operation until the battery capacity is restored. Sign in. One is only behind 1, the balance of the tandem storage battery group is a world-oriented problem, and there is a backward battery in the process of use.

Alasannya bermacam-macam, alasan produksi, dan penyebab bahan baku, dan sebagainya. 2, pemeriksaan kegagalan dan pemrosesan pertama-tama membuat baterai diisi, lalu dikosongkan dengan arus laju 2 jam. Tegangan baterai diukur secara konstan selama proses pengosongan, dan baterai mundur dengan kapasitas pengosongan dipilih.

Pertama, tambahkan 1,050 sulfat encer untuk melihat aliran elektrolit, lalu lanjutkan pengisian selama 12-15 jam. Pay attention to the temperature of the battery not more than 50 ¡ã C when charging.

Setelah pengisian daya selesai, diamkan selama 0,5-4 jam, gunakan kembali pengosongan daya selama 2 jam. Selama proses pelepasan, nilai tegangan tunggal diukur.

Jika waktu pengosongan tidak mencapai tegangan standar atau tunggal hingga 1,6V, waktu pengosongan berbeda dari baterai tunggal normal (pabrik adalah 5 menit, 6 bulan, 6 bulan Karena lebih dari 8 menit, 9 bulan berbeda lebih dari 10 menit, 13 bulan perbedaan dalam 15 menit), kemudian ulangi operasi program pengisian dan pengosongan yang disebutkan di atas hingga memenuhi persyaratan. Jika siklus pengisian dan pengosongan baterai diulang, kapasitas baterai tidak mengalami peningkatan signifikan atau masih ganjil dari sekitar 0V.

Baterai ini umumnya mengalami hubungan pendek arus listrik, atau bahan aktifnya terlepas parah, melunak, terkena sulfat ireversibel parah, dsb., tidak dapat diperbaiki, sebaiknya dibuang. Baterai yang memenuhi persyaratan dapat terus dipakai, tetapi harus dikosongkan pada tegangan konstan 15V / hanya dalam kondisi pengisian daya, bersihkan permukaan baterai, katup penutup, dan gunakan perekat PVC (atau kloroform) untuk merekatkan panel.

8. The electrolytic solution of the active substance falls off, the electrolytic solution of the battery is turbid with a reddish brown fault, and whether the battery capacity is normal, and the capacity is insufficient. The new battery voltage drops fast 1.

The fault phenomenon new battery is loaded, and the voltage drop is fast. 2, tegangan tampilan meteran pemeriksaan dan penanganan kesalahan konsisten dengan kapasitas baterai. Bila tegangan yang ditampilkan oleh instrumen tidak memenuhi tabel di atas, pabrikan harus menyesuaikannya.

Periksa apakah kabel baterai dapat diandalkan, apakah ada hubungan pendek dan koneksi tidak dapat diandalkan, dll. Kecualikan saja. Periksa apakah kendaraan listrik menyala dan arus operasinya terlalu besar, jika terlalu besar (arus mulai di atas 15A, arus 6A lebih dari 6A) harus menyesuaikan nilai batas pengontrol atau memeriksa motor.

Check if the battery capacity is low, if it is low, it should charge and discharge the battery. 10. The battery is charged 1, the fault phenomenon first checks whether the connection of the charging circuit is reliable, check whether the connection between the connection and the plug is intact, carefully check if the socket and the plug has a fire arc, there is a wire loss, the wound line, etc.

Check if the charger is damaged, the charging parameter meets the requirements: that is, the initial charging current reaches 1.6-2.5A / only; the highest charging voltage reaches 14.

8-14.9V / only, the charging floating charge conversion current is 0.3-0.

4A / only, floating The charging pressure reaches 14.0-14.4V / only.

Periksa apakah ada fenomena kering di dalam baterai, artinya baterai benar-benar kurang berfungsi. It should also be checked whether there is irreversible sulfate. The non-reversible sulfate of the plate can determine the change of its end voltage by charge and discharge.

Pada saat pengisian daya, tegangan baterai sangat cepat, beberapa tegangan satu tangan sangat tinggi, melebihi nilai normal; penurunan tegangan sangat cepat, baterai tidak macet atau macet. Dalam kasus di atas, dapat ditentukan bahwa baterai memiliki sulfat yang tidak dapat diubah kembali. 2.

Pengujian dan pemrosesan kesalahan pertama-tama akan menghubungkan sirkuit pengisian daya, dan pengisi daya harus diganti. The dry battery should add pure water or 1.050 sulfuric acid to maintain charging, discharge recovery battery capacity.

If it is found that there is irreversible sulfate, equalization charging recovery capacity should be performed. The maintenance of the dry battery is charged, which should control the maximum current 1.8A, charge 10-15 hours, three batteries are in 13.

4V / bulan. If the voltage difference between the battery exceeds 0.3V, it will illustrate an irreversible sulfate that is not synchronized.

About the battery of the inverse sulfate, to replace the whole set of batteries or activate the battery.
