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.

Baterie vstupuje do oblastí vysokonapěťového nabíjení kolem 80 % nabití kapacity. V tomto okamžiku se kyslík vysráží v kladné elektrodě a kyslík prochází otvory v přepážce. 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) Tepelná kapacita je snížena a maximální akumulací tepla je voda. Po ztrátě vody se tepelná kapacita baterie výrazně sníží a teplo, které se objeví, velmi rychle zvýší teplotu baterie. (3) V důsledku smrštění ultrajemných separátorů ze skleněných vláken v baterii po bezeztrátovém stavu se zhoršuje přilnavostí kladné a záporné desky a vnitřní odpor je velký a proces nabíjení a vybíjení se zvyšuje.

Po výše uvedeném procesu může být teplo uvnitř baterie odváděno pouze nádrží baterie. 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. Vytváření maligního cyklu způsobuje tepelnou nekontrolovatelnost, deformaci.

Fault inspection and processing a set of batteries (3) simultaneously deformed, first voltage check. Pokud je napětí v podstatě normální. Mělo by se také změřit, zda je jedno stanovení napětí zkratováno a nedochází ke zkratu, deformace je způsobena tepelným selháním.

Pozornost by měla být slyšet nabíjecí parametry nabíječky. 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.

Důležitým projevem sulfátu desky je: napětí se brzy zvýší a teplota je rychlá, teplota je rychlá a kapacita je malá, když je výboj nízký. 2. Test a zacházení s polárkou lze připsat následovně: (1) Doba skladování je příliš dlouhá, rychlost samovybíjení je vysoká a nabíjení se neprovádí.

(2) Po vybití ji včas nabijte. (3) Dlouhá doba je ve stavu nabití. (4) Nadměrné vybití.

(5) Koncentrace suchého nebo přidaného elektrolytu. Když je baterie inverzně reverzibilní sulfát, měla by být opravena podle stupně hmotnosti. Slanost je lehčí a průměrné aktivační nabíjení (tj. vyvážené nabíjení) se může vrátit k normálu.

Konkrétní metoda je následující: Konstantní limitní nabíjení napětí: První stupeň 0,18C2A se nabije na 2,7V / jedno nabití 12-24 hodin.

První stupeň konstantního proudu: 0,18C2A se nabíjí na 2,4V / jeden, druhý stupeň: 0.

05c2a nabíjení 5-12 hodin. Salterizace, je nutné nabít hydraulickou náplň a vybít, vrátit se do normálu. Specifická metoda je: nejprve přidat baterii do nízké vody nebo hustoty 1.

05 g / cm3 zředí kyselinu sírovou do bohaté kapaliny a poté nabíjí proud 0,05-0,018c2a po dobu asi 20 hodin a vypustí kapalinu z průtoku a poté proveďte test kapacity.

Opakujte výše uvedenou operaci, dokud se kapacita baterie neobnoví. 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.

Důvodem je celá řada různorodých, výrobních důvodů a příčin surovin atd. 2, the failure check and processing first make the battery to be charged, then discharged with 2 hour rate current. Během procesu vybíjení se neustále měří napětí baterie a volí se zpětná baterie s vybíjecí kapacitou.

First, add 1.050 dilute sulfate to just see the flow electrolyte, then continue charging 12-15 hours. Pay attention to the temperature of the battery not more than 50 ¡ã C when charging.

After the charging is over, stand for 0.5-4 hours, re-use 2 hour rate discharge. During the discharge process, the value of single voltage is measured.

If the discharge time does not reach the standard or single voltage to 1.6V, the discharge time differs from the normal single-finished battery (the factory is 5 minutes, 6 months, 6 months Due to more than 8 minutes, 9 months differs more than 10 minutes, 13 months difference in 15 minutes), then repeat the above-mentioned charge and discharge program operation until it meets the requirements. Pokud se jedná o opakovaný cyklus nabíjení a vybíjení, kapacita baterie se od cca 0V nijak výrazně nezvýšila nebo je stále lichá.

This battery is generally short-circuited, or the active material is severely detached softened, severe irreversible sulfate, etc., cannot be repaired, should be scrapped. Battery that meets the requirements can continue to be used, but should be exhausted under a constant voltage 15V / only charge conditions, clean the surface of the battery, an on the cap valve, and use a PVC (or chloroform) adhesive Panel bonding.

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, the fault check and handling inspection meter display voltage is consistent with battery capacity. When the voltage displayed by the instrument does not meet the above table, the manufacturer should be adjusted.

Check if the battery cable is reliable, there is short circuit and connection unreliable, etc. Have it excluded. Check if the electric vehicle starts and the operating current is too large, if it is too large (the start current is above 15A, the current 6A is over 6A) should adjust the controller limit value or check the 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.

Check if there is a dry phenomenon within the battery, that is, the battery is seriously lacking. It should also be checked whether there is irreversible sulfate. Nereverzibilní sulfát desky dokáže určit změnu jejího koncového napětí nabíjením a vybíjením.

At the time of charging, the voltage of the battery is very fast, some single-handed voltage is particularly high, exceeding normal value; the voltage drop is particularly fast, the battery is not stall or stall. Ve výše uvedeném případě lze určit, že baterie obsahuje nevratný sulfát. 2.

The test and processing of the fault will first connect the charging circuit, and the charger should be replaced. 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 / month. 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.
