What should I do in the electric car battery?

The electric vehicle battery often occurs in the use of the charging drum, resulting in two factors in the deformation of the battery drum, one is the quality problem of the battery itself, such as the internal electrolytic solution of the battery; another factor is inappropriate use of. There are several aspects of the bulk bags caused by the battery: 1. It is important to change the properties of the active material in the long-term overcharge battery.

At the same time, the charging process is also the process of electrolytic water, especially in the late stage of charging, the active substance has been fully transformed, continue Charging will speed up the decomposition of water in the battery, resulting in reduced electrolyte, and battery often charge will lead to the emergence of drum bag. When the battery is charged, after the charger turns, you will cut off the power at 2 hours, otherwise it will cause overcharge. 2, often large current charging electric car battery charging current is usually 0.

12 ~ 0.15c2, such as 20ah battery, maximum charging current is 3A. The large current is charged.

One means that the charging current of the charger is too large, the other is to use the fast charging station to quickly charge the battery, the charging current of the fast charging station generally reaches 10A, far exceeds the specified charging current. Regular large current charging will cause the battery to be lost, the battery will drum. 3, using inferior chargers, the electric motor vehicle market is full of inferior chargers, some miscellaneous electric vehicles are mostly equipped with this charger for reducing costs, many consumers do not pay attention to the quality of chargers, and they are cheap.

Buying this charger, cost is generally more than a dozen yuan. The electronic components of this charger are basically adopted by inferior materials. It is easy to damage.

The frequent problems is that the battery is not turned back, and the charging current cannot be adjusted according to the battery voltage, causing the battery to overcharge, after multiple times Battery will drum. 4, the charger does not match the battery used by the different electric vehicles, one is that the battery is different, and the second is that the voltage of the battery is different, and there are 48V, 60V, 72V, but some electric car users are using the process. In the middle, it will be used frequently, take 60V charger charger for the battery, take 20ah charger charge 12AH battery, charging voltage and current do not match, of course, will cause the battery to be filled with drums, and even new batteries A few days of drum.

5, the charging temperature is too high, and there are two aspects: one is the impact of the ambient temperature, especially in the summer, the temperature is high in summer, the internal temperature of the battery is high, and the charge is charged at high temperature, and the time is long. The battery will drum. Therefore, after using the electric car in the summer, one should not charge immediately, and the second is to charge the charging of the cool and ventilated place.

Second, it is necessary to pay attention to the battery when the battery is installed. When it is supplied, it can be dissipated. Some users are installed when the battery is installed, so that when the battery is charged, the heat is disseminated.

When charging, the battery temperature is too high, speeding up, time long, battery will have a phenomenon of drums, all manufacturers' chargers generally have personalized demand, do not replace charger at will not. Ger hewcedariya mîlê bi nisbeten dirêj e, divê hûn gelek şarjkeran bikar bînin da ku bi fermî bar bikin, şarjker di nav rojê de tê barkirin, bargiranên din bikar tîne, û şarjkerê orîjînal êvarê tê bikar anîn. Sînorê leza kontrolkerê ranekin sînorê leza kontrolkerê rakin, her çend leza hin otomobîlan were baştir kirin jî, ji bilî ewlehiya gerîdeyê, ew ê jiyana karûbarê pîlê jî kêm bike.

Parastina Destûra Bikarhêner a Charger-a Giştî danasîna barkera parastinê heye. Gelek bikarhêner li adetên manualê nanihêrin. Ji bilî pirsgirêkê, ez dixwazim di pêşerojê de rêwerzan bibînim, pir caran pir dereng, ji ​​ber vê yekê ez ê pêşî li rêwerzan binihêrim ku pir hewce ne.

Ji bo ku lêçûn kêm bikin, şarjêra heyî di bingeh de bi vibrasyona bilind nayê sêwirandin, ji ber vê yekê pêdivî ye ku şarjker di nav çal û selika bisîkletên elektrîkê de neyê danîn. Di rewşên taybetî de, divê hûn tevbigerin, lê di heman demê de şarjkerê bi plastika kef jî pak bikin, pêşî li lêdana lerizînê bigirin. Gelek şarjker di vibrasyonê re derbas bûne, û potensiometreyên wan ên hundurîn dê biherikin, bi vî rengî ku tevahiya parametreyê diherike, û di encamê de rewşa barkirinê ya ne normal.

Digel vê yekê, pêdivî ye ku meriv bala xwe bide barkirina guheztina barkêşê, wekî din ew ê ne tenê bandorê li jiyana barkêşê bike, lê di heman demê de dravê termal jî dikare bandorê li rewşa barkirinê bike. Ev ê zirarê bide pîlê. Ji ber vê yekê, ew jî pir girîng e ku şarjê biparêze.

Her roj, her çend kapasîteya weya nûvekirinê ne hewce be jî, ew dikare 2 û 3 rojan were bikar anîn, lê tê pêşniyar kirin ku hûn her roj şarj bikin, da ku pîlê di çerçoveyek hûrdeyî de be, dê jiyana bateriyê were dirêj kirin. Hin karanîna destpêkê ya bikarhênerên têlefonên desta difikirin ku pîlê bi bingehîn di pêşerojê de tê bikar anîn, ev nêrîn xelet e, feydeyên bîranîna batarya-acid ne ew qas xurt in. Her gav bavêjin ku jiyana pîlê nisbeten mezin e.

Piraniya bargiran destnîşan dikin ku ronahiya çêkirî ya ronahiyê destnîşan dike ku pîlê dikare ji% 97 heta 99% di elektrîkê de were barkirin. Her çend tenê 1% heya 3% ê elektrîkê, bandora kapasîteya domdar hema hema nayê paşguh kirin, lê ew ê di heman demê de kombûnek di bin barkirinê de jî çêbike, ji ber vê yekê pîlê bi veguheztina elektrîkê tije dibe, û barkirina herikînê dê bi qasî ku gengaz were domandin, û vulkanîzekirina pîlê jî sûdmend e. .
