Malalim na pagsusuri: Lithium battery forklift battery cycle life at attenuation law

Malalim na pagsusuri: Lithium battery forklift battery cycle life at attenuation law(larawan1)

Sa pagpapasikat ng mga forklift ng baterya ng lithium sa warehousing, logistik at iba pang mga sitwasyon, ang cycle ng buhay at pagpapahina ng mga baterya ay naging mga pangunahing tagapagpahiwatig ng gastos na binibigyang pansin ng mga user. Ang pag-unawa sa mga nauugnay na batas ay epektibong makakatulong sa mga user na gamitin ang mga baterya nang makatwiran at mabawasan ang mga pangmatagalang gastos sa pagpapatakbo.

Mayroong malinaw na pamantayan sa industriya para sa buhay ng cycle ng mga baterya ng lithium-ion forklift. Karaniwan, kapag ang aktwal na magagamit na kapasidad ng baterya ay bumaba sa 80% ng na-rate na kapasidad, ang kabuuang bilang ng mga kumpletong cycle ng pag-charge at pagdiskarga na nakumpleto noon ay ang nominal na cycle ng buhay ng baterya. Ang kumpletong cycle ng pag-charge at pagdiskarga dito ay tumutukoy sa kumpletong proseso ng pagdiskarga ng baterya mula sa isang ganap na naka-charge na estado patungo sa isang nakatakdang cut-off na boltahe, at pagkatapos ay ganap na na-charge sa isang na-rate na boltahe. Ang mababaw na pag-charge at mababaw na pagdiskarga sa pang-araw-araw na paggamit ay hindi mabibilang bilang isang cycle lamang, kaya ang aktwal na paggamit Ang kabuuang bilang ng mga cycle ay kadalasang mas mataas kaysa sa pangunahing halaga ng pangalan ng produkto.

Sa iba 't ibang mga sitwasyon sa paggamit, may mga makabuluhang pagkakaiba sa rate ng attenuation ng mga baterya ng lithium battery forklift. Sa conventional operation scenario, ang ambient temperature ay pinananatili sa pagitan ng 10 degrees Celsius at 30 degrees Celsius, at ang single-trip operation load ay hindi lalampas sa 70% ng rated load. Kapag ang single discharge depth ay kinokontrol sa humigit-kumulang 60%, ang attenuation rate ng baterya ay pananatilihin sa mababang antas. Sa bawat 100 kumpletong cycle na nakumpleto, ang pagbaba ng kapasidad ay karaniwang nasa pagitan ng 0.3% at 0.5%. Kung ikaw ay nasa isang matinding kapaligiran sa pagtatrabaho sa loob ng mahabang panahon, tulad ng ambient temperature na mas mababa sa minus 10 degrees Celsius o mas mataas sa 45 degrees Celsius, o madalas na ganap na na-load at na-discharge na may mataas na kasalukuyang, at ang baterya ay na-discharge sa cut-off na boltahe sa bawat oras bago singilin, ang attenuation rate ng baterya ay tataas ng 2 hanggang 3 beses. Ang mataas na temperatura na kapaligiran ay maaari ring magpalala sa pagkonsumo ng panloob na electrolyte at higit pang paikliin ang aktwal na buhay ng serbisyo ng baterya.

Ang pag-master ng mga makatwirang paraan ng paggamit at pagpapanatili ay maaaring epektibong maantala ang pagpapahina ng baterya at pahabain ang cycle ng buhay. Sa pang-araw-araw na pamamahala sa pag-charge at pagdiskarga, subukang iwasan ang ganap na pag-alis ng laman ng baterya at muling pag-charge nito. Pagkatapos ng operasyon, muling i-charge ang baterya sa tamang oras. Kapag ang baterya ay idle nang mahabang panahon, panatilihin itong naka-imbak sa pagitan ng 40% at 60%. Kumpletuhin ang pag-charge at pagdiskarga, at i-calibrate ang mga parameter ng kapasidad ng baterya. Sa panahon ng operasyon, subukang iwasan ang matinding temperatura na kapaligiran. Sa mataas na temperatura o mababang temperatura ng panahon, ang oras para sa isang biyahe ay maaaring naaangkop na paikliin upang maiwasan ang baterya na maging sobrang init o sobrang lamig sa loob ng mahabang panahon. Sa pang-araw-araw na pagpapanatili, suriin ang contact ng interface ng baterya bawat quarter upang maiwasan ang abnormal na paglabas na dulot ng mahinang contact. Linisin ang alikabok at langis sa ibabaw ng baterya sa oras upang panatilihing hindi nakaharang ang channel ng pagwawaldas ng init, na maaari ring mabawasan ang posibilidad ng abnormal na pagkabulok
