Kumvetsetsa Zodziwikiratu za Battery ya Gofu Nthawi Zonse

Kutalika kwa batire ya ngolo ya gofu

Ngolo za gofu ndizofunikira kuti mukhale ndi mwayi wabwino wosewera gofu. Akupezanso kugwiritsidwa ntchito kwakukulu m'malo akuluakulu monga mapaki kapena masukulu aku University. Mbali yofunika kwambiri yomwe idawapangitsa kukhala okongola kwambiri ndikugwiritsa ntchito mabatire ndi mphamvu yamagetsi. Izi zimathandiza kuti ngolo za gofu zizigwira ntchito popanda kuwononga phokoso komanso kutulutsa phokoso. Mabatire ali ndi nthawi yeniyeni ya moyo ndipo, ngati apitirira, amabweretsa kutsika kwa makina ogwiritsira ntchito komanso kuwonjezeka kwa kuthekera kwa kutayikira ndi nkhani zachitetezo monga kuthawa kwa kutentha ndi kuphulika. Chifukwa chake, ogwiritsa ntchito ndi ogula amakhudzidwa kuti abatire ya gofuikhoza kukhalitsa kuti ipewe masoka ndikugwiritsa ntchito chisamaliro choyenera pakafunika.

Yankho la funsoli mwatsoka si laling'ono ndipo zimadalira zinthu zingapo, imodzi mwa izo ndi chemistry ya batri. Nthawi zambiri, batire ya gofu ya lead-acid ikuyembekezeka kukhala pakati pa zaka 2-5 pa avareji m'ngolo za gofu zomwe zimagwiritsidwa ntchito poyera ndi zaka 6-10 mwa eni ake. Kwa nthawi yayitali ya moyo, ogwiritsa ntchito amatha kugwiritsa ntchito mabatire a lithiamu-ion omwe akuyembekezeka kupitilira zaka 10 ndikufikira zaka pafupifupi 20 pamagalimoto aumwini. Mtundu uwu umakhudzidwa ndi othandizira angapo ndi zikhalidwe, zomwe zimapangitsa kusanthula kukhala kovuta. M'nkhaniyi, tilowa mozama muzinthu zodziwika bwino komanso zokopa kwambiri pamabatire akungolo ya gofu, pomwe tikupereka malingaliro ngati zingatheke.

Chemistry ya batri

Monga tanena kale, kusankha kwa chemistry ya batri kumatsimikizira kutalika kwa moyo wa batire ya gofu yomwe imagwiritsidwa ntchito.

Mabatire a lead-acid ndi omwe amadziwika kwambiri, chifukwa cha mitengo yawo yotsika komanso kuwongolera bwino. Komabe, amaperekanso moyo wocheperako womwe umayembekezeredwa, avareji ya zaka 2-5 pamangolo okwera gofu omwe amagwiritsidwa ntchito pagulu. Mabatirewa ndi olemetsanso kukula kwake komanso si abwino kwa magalimoto ang'onoang'ono omwe ali ndi mphamvu zambiri. Mmodzi ayeneranso kuyang'anira kuya kwa kutulutsa kapena mphamvu yomwe ilipo mu mabatire awa, kotero sikulimbikitsidwa kuwagwiritsa ntchito pansi pa 40% ya mphamvu zosungidwa kuti asawonongeke kosatha electrode.

Mabatire a ngolo ya gofu ya gel lead-acid akuperekedwa ngati njira yothetsera kulephera kwa mabatire amtundu wa lead-acid gofu. Pankhaniyi, electrolyte ndi gel osakaniza m'malo madzi. Izi zimachepetsa utsi komanso kuthekera kwa kutayikira. Zimafunika kukonzanso pang'ono ndipo zimatha kugwira ntchito kutentha kwambiri, makamaka kutentha kozizira, komwe kumadziwika kuti kumawonjezera kuwonongeka kwa batri ndipo, chifukwa chake, kuchepetsa moyo.

Mabatire a gofu a lithiamu-ion ndi okwera mtengo kwambiri koma amakhala ndi moyo wautali kwambiri. Mwambiri, mutha kuyembekezera abatire ya gofu ya lithiamu-ionkukhala pakati pa zaka 10 mpaka 20 kutengera zizolowezi zogwiritsa ntchito komanso zinthu zakunja. Izi makamaka zimatengera kapangidwe ka ma elekitirodi ndi ma electrolyte omwe amagwiritsidwa ntchito, zomwe zimapangitsa kuti batire ikhale yogwira ntchito bwino komanso yolimba kwambiri kuti iwonongeke ngati pakufunika katundu wambiri, kuyitanitsa mwachangu, komanso kugwiritsa ntchito nthawi yayitali.

Zinthu zogwirira ntchito ziyenera kuganiziridwa

Monga tanena kale, chemistry ya batri sizomwe zimatsimikizira moyo wa batri ya ngolo ya gofu. M'malo mwake, ndikulumikizana kolumikizana pakati pa chemistry ya batri ndi machitidwe angapo ogwiritsira ntchito. Pansipa pali mndandanda wazinthu zomwe zimakhudza kwambiri komanso momwe zimalumikizirana ndi chemistry ya batri.

. Kuchucha mochulukira ndi kutulutsa mochulukitsitsa: Kuchapira kapena kutulutsa batire mopitilira muyeso wina kumatha kuwononga maelekitirodi kwamuyaya. Kuchulukitsitsa kumatha kuchitika ngati batire ya ngolo ya gofu ikasiyidwa motalika kwambiri pakulipiridwa. Izi sizodetsa nkhawa kwambiri pankhani ya mabatire a lithiamu-ion, pomwe BMS nthawi zambiri imakonzedwa kuti ichotse kulipiritsa ndikuteteza kuzinthu zotere. Kutulutsa kochulukira, komabe, ndikocheperako kugwiridwa. Kachitidwe kakutulutsa kumatengera kagwiritsidwe ntchito ka ngolo ya gofu ndi mayendedwe omwe amagwiritsidwa ntchito. Kuchepetsa kuya kwa kutulutsa kungachepetse mtunda womwe ngolo ya gofu imatha kufikitsa pakati pa kuzungulira kolipiritsa. Pamenepa, mabatire a gofu a lithiamu-ion amakhala ndi mwayi chifukwa amatha kupirira ma cyclers akuya osawonongeka kwambiri poyerekeza ndi mabatire a lead-acid.

. Kulipiritsa mwachangu komanso kumafuna mphamvu zambiri: Kulipiritsa mwachangu komanso kufuna kwamphamvu kwambiri ndi njira zotsutsana pakulipiritsa ndi kutulutsa koma amavutika ndi vuto lomwelo. Kuchulukirachulukira kwamakono pa maelekitirodi kungayambitse kutaya kwa zinthu. Apanso, mabatire a gofu a lithiamu-ion ndioyenera kuyitanitsa mwachangu komanso kunyamula mphamvu zambiri. Pankhani ya kugwiritsa ntchito ndi magwiridwe antchito, mphamvu yayikulu imatha kuthamangitsa kwambiri pangolo ya gofu komanso kuthamanga kwambiri. Apa ndipamene kayendetsedwe ka ngolo ya gofu kungakhudze moyo wa batri limodzi ndi kagwiritsidwe ntchito. Mwa kuyankhula kwina, mabatire a ngolo ya gofu yogwiritsidwa ntchito pa liwiro lotsika pa bwalo la gofu amatha kupitirira mabatire a ngolo yachiwiri ya gofu yomwe imagwiritsidwa ntchito pa liwiro lapamwamba kwambiri pabwalo lomwelo.

. Mikhalidwe ya chilengedwe: Kutentha kwambiri kumadziwika kuti kumakhudza nthawi ya moyo wa batri. Kaya itayimitsidwa padzuwa kapena kuzizira kozizira kwambiri, zotsatira zake zimakhala zowononga mabatire a ngolo za gofu. Njira zina zaperekedwa pofuna kuchepetsa vutoli. Mabatire a ngolo ya gofu a Gel Lead-Acid ndi njira imodzi yothetsera vutoli, monga tanenera kale. Ma BMS ena amayambitsanso kuyitanitsa kwa mabatire a lithiamu-ion kuti awatenthetse asanakwere kwambiri C-rate kuti achepetse kuyika kwa lithiamu.

Izi ziyenera kuganiziridwa pogula batire ya ngolo ya gofu. Mwachitsanzo, aS38105 LiFePO4 batire yochokera ku ROYPOWAmanenedwa kuti amakhala zaka 10 asanafike kumapeto kwa moyo. Ichi ndi mtengo wapakati potengera kuyezetsa kwa labotale. Kutengera chizolowezi chogwiritsa ntchito komanso momwe wogwiritsa ntchito amasamalirira batire ya ngolo ya gofu, nthawi yomwe amayembekezeka kapena zaka zogwirira ntchito zitha kutsika kapena kupitilira kuchuluka kwa batire la ngolo ya gofu.

Mapeto

Mwachidule, nthawi ya moyo wa batire ya ngolo ya gofu imasiyana malinga ndi kagwiritsidwe ntchito, kagwiritsidwe ntchito, ndi momwe batire imapangidwira. Popeza awiri oyambirira ndi ovuta kuwerengera ndikuwerengeratu, munthu akhoza kudalira mavoti apakati potengera chemistry ya batri. Pachifukwa chimenecho, mabatire a gofu a lithiamu-ion amapereka moyo wautali koma mtengo woyambira wokwera poyerekeza ndi moyo wotsika komanso mtengo wotsika wa mabatire a lead-acid.
