Omwachidule:

Posachedwapa, Automotive Industry Standards Committee (AISC) yatulutsa muyezo wa AIS-156 ndi AIS-038 (Rev.02) Amendment 3. Zoyeserera za AIS-156 ndi AIS-038 ndi REESS (Rechargeable Energy Storage System) zamagalimoto, ndi zatsopano. kope likuwonjezera kuti ma cell omwe amagwiritsidwa ntchito mu REESS akuyenera kuyesa mayeso a IS 16893 Gawo 2 ndi Gawo 3, ndipo osachepera 1 deta yotulutsa-charge iyenera kuperekedwa. Zotsatirazi ndizofotokozera mwachidule zofunikira za mayeso a IS 16893 Gawo 2 ndi Gawo 3.

Chithunzi cha 16893-2

IS 16893 imagwiritsidwa ntchito ku cell yachiwiri ya lithiamu-ion yomwe imagwiritsidwa ntchito pamagalimoto apamsewu oyendetsedwa ndi magetsi. Gawo 2 likunena za kuyesa kudalirika komanso kuzunzidwa. TS EN 62660-2 IEC 62660-2: 2010 "Ma cell achiwiri a lithiamu-ion omwe amagwiritsidwa ntchito pamagalimoto apamsewu oyendetsedwa ndi magetsi - Gawo 2: Kuyesa kudalirika ndi kuzunza" lofalitsidwa ndi International Electrotechnical Commission (IEC). Zinthu zoyeserera ndi: kuwunika mphamvu, kugwedezeka, kugwedezeka kwamakina, kuphwanya, kupirira kutentha kwambiri, kupalasa njinga kutentha, kuzungulira kwakunja, kuthamangitsa komanso kutulutsa mokakamiza. Zina mwazo ndi zinthu zazikulu zoyeserera:

• Kupirira kutentha kwambiri: ma cell a 100 % SOC (BEV) ndi 80 % SOC (HEV) amayenera kuyikidwa pa 130 ℃ kwa 30min.
• Kunja kwakanthawi kochepa: ma cell a 100% SOC amafunika kufupikitsidwa kwa mphindi 10 pakukana kwakunja kwa 5mΩ.
• Kuchulukirachulukira: kugwiritsa ntchito voteji kuwirikiza kawiri mphamvu yamagetsi yomwe wopanga amafotokozera kapena mphamvu ya 200% SOC ndiyofunikira. BEV iyenera kulipitsidwa ndi 1C ndipo HEV iyenera kulipitsidwa ndi 5C.

Zomwe zili pamwambazi ndizokhudza magwiridwe antchito a cell. Amafunikira magwiridwe antchito apamwamba azinthu zama cell, monga cholekanitsa. Choncho opanga ayenera kumvetsera kwambiri iwo

Mayeso atatu omwe ali pamwambawa amafunikira chidwi chowonjezera pachitetezo chachitetezo chaselo, makamaka chitetezo cha zinthu zamkatis, monga diaphragm.

Chithunzi cha 16893

IS 16893 Gawo 3 limakhudza zofunikira zachitetezo. TS EN 62660-3 Maselo achiwiri a lithiamu-ion omwe amagwiritsidwa ntchito pamagalimoto apamsewu oyendetsedwa ndi magetsi - Gawo 3: Zofunikira pachitetezo Zinthu zoyeserera ndi: kuwunika mphamvu, kugwedezeka, kugwedezeka kwamakina, kuphwanya, kupirira kutentha kwambiri, kukwera njinga yamoto, kuthira mochulukira, kutulutsa mokakamiza ndikukakamiza kuyenda kwapakati. Zinthu zotsatirazi ndi zofunika.

• Njira zoyesera za kugwedezeka, kugwedezeka kwamakina, kuyendetsa njinga zamoto, kuzungulira kwafupipafupi kumatchula IEC 62660-2: 2010 Kwenikweni, njira yoyesera ndiyofanana ndi IS 16893 Gawo 2.
• Kupirira kwa kutentha kwakukulu: Kuphatikiza pa kufunika koyikidwa pa 130 ℃ kwa 30min, kuyang'ana kwa ola limodzi pa selo kumafunikanso mutatha kuzimitsa chowotcha.
• Kuchulukirachulukira: kugwiritsa ntchito voliyumu ya 120 % yamagetsi apamwamba omwe wopanga amafotokozera, kapena mtengo wa 130 % SOC ukufunika.
• Magawo oyesera a kuphwanya ndi kutulutsa mokakamiza ndi osiyana pang'ono ndi IEC 62660-2: 2010.

Njira yoyesera yokakamiza mkati mwafupipafupi imatengera IEC 62619.

Malangizo Ofunda:

Ndizofunikira kudziwa kuti ngakhale IS 16893 Gawo 2 ndi IS 16893 Gawo 3 ali ndi zinthu zina zoyeserera, zigamulo sizifanana. Gawo 2 liyenera kuwunika kudalirika kwa maselo, kusonkhanitsa deta yodalirika yodalirika komanso machitidwe ozunza. Lipoti loyesa liyenera kulemba deta yamakono, magetsi ndi kutentha ndikufotokozera zotsatira za mayesero a maselo, ndipo palibe chofunikira kuti mudziwe ngati zotsatira za mayeso zadutsa kapena ayi. Komabe, Gawo 3 limafotokoza mikhalidwe yopambana mayeso, monga selo silingagwire moto ndikuphulika panthawi yoyeserera, ngati sichoncho, mayesowo adzalephera.

Ngati muli ndi mafunso ena okhudzana ndi muyezowu komanso kugwiritsa ntchito mayeso, chonde omasuka kulumikizana ndi makasitomala athu kapena malonda.
