Mabatire a NiMH ankagwiritsidwa ntchito kwambiri m'zida zam'mbuyomu ndipo amapezekabe m'zida zina zomwe zimafuna kulimba komanso kusinthidwa mosavuta kwa mabatire. Ali ndi ubwino woti amalekerera kugwiritsidwa ntchito molakwika kuposa mitundu ina ya Li-ion ndipo ndi otetezeka. Komabe, ali ndi mphamvu zochepa, nthawi zambiri amadzitulutsa okha, ndipo ndi olemera kwambiri poyerekeza ndi mphamvu yomweyo.
5. Mabatire oyambira (otayidwa): Lithium-thionyl chloride ndi alkaline
Pazida zadzidzidzi kapena zida zomwe sizigwiritsidwa ntchito kawirikawiri koma ziyenera kukhala zokonzeka nthawi zonse, mabatire oyambira nthawi zambiri amasankhidwa chifukwa cha nthawi yayitali yosungiramo zinthu. Zitsanzo zikuphatikizapo masensa ena, zida zowunikira zakutali zotsika kwambiri, kapena zida zosungira. Zoyipa zake n'zodziwikiratu: sizingadzazidwenso mphamvu ndikupanga zinyalala zambiri, kotero ziyenera kuganiziridwanso za kayendedwe ka zinthu ndi zachilengedwe.
Dongosolo Loyang'anira Mabatire (BMS): "ubongo" wa chitetezo cha mabatire
Pafupifupi zipangizo zonse zamakono zachipatala zomwe zimagwiritsa ntchito mabatire otha kubwezeretsedwanso zimafuna Battery Management System (BMS). BMS imateteza batire ndipo imatsimikizira kuti ikugwira ntchito bwino mwa:
- Chitetezo cha kukweza ndi kutulutsa mopitirira muyeso
- Chitetezo cha overcurrent ndi short circuit
- Kuwunika kutentha pogwiritsa ntchito sensa ya kutentha
- Kuyerekeza kwa State of Charge (SoC) ndi State of Health (SoH)
- Kulinganiza maselo (kwa mabatire a maselo ambiri)
- Kulemba zochitika (pa zipangizo zina)
Pankhani yachipatala, BMS imathandizanso kuti ogwiritsa ntchito azitha kuona bwino: chizindikiro cholondola cha batri sichongothandiza, koma chimathandiza kuonetsetsa kuti chithandizocho sichimaima mwadzidzidzi. Kuyerekeza kolakwika kwa SoC kungayambitse kuzimitsa chipangizo panthawi yovuta kwambiri. Chifukwa chake, ma algorithms oyezera monga kuwerengera kwa coulomb ndi mitundu yochokera ku voltage nthawi zambiri amaphatikizidwa kuti akonze kulondola.
Mavuto a kapangidwe: chitetezo, kuyeretsa thupi, ndi malamulo
Kapangidwe ka mabatire a zipangizo zachipatala kamasiyana ndi ka zipangizo zomwe anthu amagwiritsa ntchito. Kuwonjezera pa kufunika chitetezo, zipangizozi nthawi zambiri zimayeretsedwa kwambiri pogwiritsa ntchito mankhwala ophera tizilombo toyambitsa matenda. Izi zikutanthauza kuti chipinda cha batire, kutseka, ndi chivundikiro chake ziyenera kukhala zosagwira mankhwala ndipo sizimalowa madzi. Pa zipangizo zomwe zimagwiritsidwa ntchito m'malo azachipatala, miyezo yolimbana ndi kutayikira ndi fumbi (monga, IP protection rating) ingafunike.
Malamulo amakhudzanso zisankho za kapangidwe kake. Opanga nthawi zambiri ayenera kuyang'anira miyezo ya chitetezo chamagetsi ndi zoopsa ndikuchita bwino kwambiri pakuwongolera zoopsa: chimachitika ndi chiyani ngati batire yatsika? Kodi pali alamu? Kodi chipangizocho chimalowa mu mode yotetezeka? Kodi pali batire yosungira kapena yosinthika? Zonsezi zikuphatikizidwa mu njira yoyesera yaukadaulo ndi kutsatira malamulo.
Kuchaja: mwachangu, motetezeka komanso mosavuta kugwiritsa ntchito
Zipangizo zachipatala zonyamulika ziyenera kukhala zosavuta kuzichaja, koma izi siziyenera kuwononga moyo wa batri kapena chitetezo. Kuchaja mwachangu kumatha kugwira ntchito, makamaka pazida zoyendera kapena zogawana. Komabe, kuchaja mwachangu kumabweretsa kutentha. Chifukwa chake, mapangidwe a chaja nthawi zambiri amadalira kuwongolera kwamagetsi/magetsi (CC-CV), kuyang'anira kutentha, ndipo nthawi zina amachepetsa kuchaja mwachangu pamlingo winawake wa kutentha.
Zipangizo zina zimagwiritsa ntchito malo oimikapo magalimoto kuti akatswiri azaumoyo athe kungosiya chipangizocho kuti chizichajidwa, zomwe zimachepetsa kulumikizidwa kwa chingwe ndikuwonjezera ukhondo. Kumbali ina, zipangizo zapakhomo zimagwiritsa ntchito USB-C kuti zikhale zosavuta. Vuto ndikuwonetsetsa kuti ma adapter akugwirizana ndi mtundu wa chaji komanso kuti chaji ikwaniritse zofunikira zachipatala.
Zochitika zaposachedwa: mabatire olimba, osinthasintha, ndi mphamvu yosakanikirana
Kafukufuku wa mabatire akupitilizabe kupita patsogolo. Madera ena abwino kwambiri pa zipangizo zachipatala zonyamulika ndi awa:
– Batire yolimba: imalowa m'malo mwa ma electrolyte amadzimadzi ndi olimba kuti iwonjezere chitetezo ndi kuchuluka kwa mphamvu. Ngati ingagwiritsidwe ntchito m'mabizinesi, izi zitha kuchepetsa chiopsezo cha kutuluka kwa madzi ndi kutentha.
