I. Safety valve pressure over high valve controlled lead-acid battery is provided with a row of safety valves in order to ensure safe use, when the pressure in the battery rises, the safety valve will automatically open, to ensure the internal and external air pressure balance inside and outside the battery. Batareyada bosim ko&39;tarilganda, xavfsizlik klapanini an&39;anaviy tarzda ochib bo&39;lmaydi.

Uzoq vaqt davomida batareyadagi bosim juda yuqori bo&39;lganligi sababli, ichki va tashqi gaz bosimi muvozanatsiz bo&39;lib, barabanlar hodisasi bo&39;ladi. Ikkinchi. Haddan tashqari to&39;ldirilgan akkumulyator batareyasi muhandislari akkumulyatorning haddan tashqari zaryadlanishi va haddan tashqari zaryadsizlanishining oldini olishi kerakligini bir necha bor ta&39;kidladilar va ortiqcha zaryad batareyada yomon gaz kompozitsiyalariga olib keladi.

Batareyada batareyaning qattiq reaktsiyasi mavjud bo&39;lib, u katta miqdorda issiqlikka ega, bu elektrolitlarga olib keladi. Gazlashtirishni parchalash, batareya baraban. III.

Zaryadlash oqimi juda katta. Batareya ko&39;rsatmalariga ko&39;ra, BT-HSE12V batareyasining zaryadlash oqimi 0,25C dan oshmasligi kerak va tavsiya etilgan tavsiyalar 0 dir.

1c (10a), zaryadlash oqimi ushbu maqbul oqim qiymatidan kattaroq bo&39;lsa-da, elektrod plitasining juda tez yog&39;ishiga olib kelishi oson, bu esa o&39;z navbatida etarli darajada kimyoviy reaktsiyalarga olib keladi. Bu vaqtda batareya ichidagi harorat tez ko&39;tariladi. Egzoz o&39;z vaqtida bo&39;lmasa, batareyali tamburlar hodisasi bo&39;ladi.

IV. Suzuvchi zaryad juda yuqori o&39;rnatilgan va zaryadlash oqimi katta bo&39;lib, musbat plastinkadagi o2 tezlashishiga olib keladi va u salbiy kompozitsion kabi yaxshi emas va batareyadagi harorat ko&39;tarilishi ham juda tez, egzozda Bosim matbuotga yetganda, VRLA batareyasi deformatsiyalanadi. Elektr transport vositasining lityum-ion batareyasi barabanlarining sababi: 1, zaryadlovchining sifati past, narx urushi halok bo&39;ldi, zaryadlovchining sifati pasayadi, pastki plastinka, ta&39;mirlash yoki past darajadagi qurilmadan foydalanish, isitma, parametrlarning siljishi aniq emas, shuning uchun zaryadlash chegarasi nazoratdan tashqarida, batareyaning ichki gaz ekstruziyasi hatto batareyaning delinishiga olib keladi. portlash.

2, zaryadlash vaqti juda uzoq, ba&39;zi foydalanuvchilarning vaqt tushunchasi yo&39;q, zaryadlovchi to&39;liq avtomatik to&39;xtashni kiritish, men so&39;ramayman, ba&39;zilari hatto ikki kun va ikki kechani to&39;ldiradi, men uni uzoq vaqt ishlatganman, elektr avtomobil lityum ion Batareya to&39;plamining ishlash muddati tahdid soladi. Haddan tashqari zaryadlangan gazni yuvish elektrod plitasining katta miqdoriga olib kelishi mumkin bo&39;lsa, bu ichki faol moddaning tushishiga olib keladi, batareyaning ishlash muddatini qisqartiradi, shuning uchun batareyaning behuda bo&39;lishi, elektrolitlarning parchalanishiga ta&39;sir qiladi, shuning uchun batareyaning harorati ko&39;tariladi, uni Dori qiling! Vana teshigi tiqilib qoladi, ichki gaz bosimini oshiradi, batareya korpusining deformatsiyasiga olib keladi va bo&39;linish shishib ketadi. 4, zaryadlovchini zaryadlovchi bilan unuting, faqat bittasini yoki bir nechta elektr avtomobil o&39;lchamli zaryadlovchilar oilasini oling, bu juda keng tarqalgan, har bir elektr avtomobil akkumulyatori markasi o&39;z interfeysiga ega, oqim qiymati, turli elektr Avtomobilda har xil zaryadlash kuchlanishlari bo&39;lishi mumkin, zaryadlash oqimi boshqacha, tabiiy zaryadlash vaqti va zaryadlash samaradorligi boshqacha, va zaryadlovchi, batareya kichik, batareya kichik, zaryadlovchi kichik, zaryadlovchi kichik katta, zaryadlash, issiqlik nazoratdan tashqarida, baraban bo&39;ladi.

Yuqorida lityum-ion batareyalar, akkumulyatorlar, elektr avtomobil akkumulyatori barabanlarining sabablarini tahlil qilish. Temir fosfatli batareyalar to&39;plamining xavfsizlik muammolari odamlarning doimiy e&39;tibor mavzusi bo&39;lib kelgan, garchi lityum-ion batareyalar texnologiyasi doimiy ravishda takomillashtirilsa-da, ammo xavfsizlik xavfi hali ham mavjud. Batareyaning xavfsiz ishlashi yaxshiroq lityum-ion batareya to&39;plamiga ega emas.

Lityum-ion batareya paketlarini ishlatishda baraban sumkasi hodisasi mavjud bo&39;lsa, batareyani kichik seriyali almashtirish tavsiya etiladi, chunki eng muhimi. 1. The charging process takes out the lithium ion from the positive electrode lattice under the driving process, and is embedded in the negative electrode lattice.

Kuchlanish 3V dan past, birinchi navbatda oldindan zaryadlashni amalga oshiring, zaryadlash oqimi belgilangan oqimning 1/10 qismini tashkil qiladi va kuchlanish 3V ga ko&39;tariladi, standart zaryadlash jarayoniga kiring. The standard charging process is: When the current is constant, the battery voltage rises to 4.20V, change to constant pressure charging, keep the charging voltage of 4.

20V. Bu vaqtda zaryadlash oqimi asta-sekin kamayadi va oqim belgilangan zaryad oqimining 1/10 qismiga tushganda, zaryadlash tugaydi. Bu umumiy lityum-ion batareyani zaryad qilish jarayonidir, agar lityum-ion batareya aqlli qurilmada mavjud bo&39;lsa, uning zaryadlash rejimi aqlli qurilma dasturi tomonidan boshqariladi.

2. Battery discharge, at this time, the electronic E on the negative electrode is ran from the positive electrode through the external circuit. Come together.

By understanding the charge and discharge process of lithium-ion batteries, we can understand from microscopic, the capacity of the battery is actually the amount of charge containing the battery. The larger the current, the faster the discharge speed, the shorter the battery used. Why is the battery that the battery does not use the drum in normal use or long time? There are two phenomena in the process of charge and discharge: one.

Excessive charging caused by overcharge can result in all the lithium atoms in the positive electrode material to the negative electrode material, resulting in a transition of the positive absorbed grid, which is also an important reason for the decline in lithium-ion battery. During this process, the lithium ions of the negative electrode are increasing, and the over-accumulation allows the lithium atom to be crystallized, so that the battery is bulging. two.

In the first charge and discharge process of the liquid lithium ion battery, the electrode material is reacted on the solid-liquid phase interface in the liquid lithium ion battery, forming a passivation layer covering the surface of the electrode material. The formed passivation layer film can effectively prevent the passage of the electrolyte molecule, but Li + can be freely embedded and disengaged by the passivation layer, and has the characteristics of the solid electrolyte, so this layer of passivation film is referred to as a solid electrolyte interface mask. (SolideElectrolyteinterface), referred to as SEI.

The SEI film will protect the negative electrode material, so that the material structure is not easy to collapse, and the cycle life of the electrode material can be added. SEI plyonkasi doimiy emas, zaryadlash va tushirish jarayonida ozgina o&39;zgarishlar bo&39;ladi, ba&39;zi organik moddalarning qaytariladigan o&39;zgarishlar bo&39;lishi muhimdir. After the battery is excessively discharged, the SEI film occurs reversible to break the ring, and the SEI destruction of the negative electrode material makes the negative electrode material collapse, thereby forming a bulk phenomenon.
