Limbikitsani Ntchito Zaulimi Ndi Mphamvu Zodalirika za Lithium
Pamene ulimi ukupita ku magetsi, magetsi anzeru, ogwira ntchito, komanso okhalitsa amakhala ofunika. Ukadaulo wa polinovel lithium batire pack umapereka magwiridwe antchito amphamvu pamakina osiyanasiyana aulimi, kuphatikiza mathirakitala, zosakaniza zodyetsa, zonyamula ma telefoni, ndi zonyamula zotsatiridwa. Mabatirewa amapereka mphamvu zotalikirapo-zosatha, kuyitanitsa mwachangu, komanso kutsika mtengo wogwiritsa ntchito, pamene amalimbikitsa{3}}zaulimi wocheperako komanso wosasamala zaulimi. Polinovel imapereka mayankho osinthika amagetsi ogwirizana ndi zofunikira zamphamvu pazaulimi zosiyanasiyana, kupititsa patsogolo magwiridwe antchito a zida komanso kuyanjana ndi chilengedwe. Pamodzi, titha kuthandizira ulimi wokhazikika padziko lonse lapansi.

Makina oziziritsira amadzimadzi otsogola ndi ofunikira kuti pakhale kutentha koyenera mu batri ya lithiamu yomwe imakhudza nthawi yomwe batire la lithiamu limakhala pa-zaulimi wamphamvu kwambiri. Makina ozizirira amagwiritsa ntchito matchanelo a serpentine okhala ndi ma hydraulic diameters of 5-10 mm opangidwa mu mbale zozizira za aluminiyamu. Kutentha kwa madzi ozizira nthawi zambiri kumayambira 5-15 malita pa mphindi imodzi, pogwiritsa ntchito 50/50 ethylene glycol-madzi osakaniza okhala ndi corrosion inhibitors.
Ma coefficients otengera kutentha amafikira 500-2000 W/m²K kutengera kuthamanga kwa mafunde ndi geometry ya tchanelo. Dongosololi limasunga kutentha kwa ma cell pakati pa 15-35 digiri ndi kutentha kofanana mkati mwa ± 3 digiri kudutsa paketi. Ma computational fluid dynamics amawongolera masanjidwe a tchanelo kuti achepetse kutsika ndikuwonjezera kutentha, ndikofunikira kuti mudziwe kuti batire la lithiamu limakhala nthawi yayitali bwanji pantchito zaulimi.
Phase Change Material Integration
Ma batire ena aulimi amaphatikiza zinthu zosinthira magawo (PCMs) pakuwongolera kutentha kwapang'onopang'ono. Parafini{{1}ma PCM okhala ndi malo osungunuka pakati pa 35-madigiri 45 amaikidwa mu aluminiyamu kapena zotengera za polyethylene zolimba kwambiri zoyikidwa pakati pa ma module a batri. Kutsegula kwa PCM kumayimira 5-10% ya kulemera kwa paketi yonse, kumapereka kutsekemera kwamafuta panthawi yamphamvu kwambiri.
Active Heating Systems
Kugwira ntchito kwanyengo yozizira kumafunikira makina otenthetsera kuti asunge magwiridwe antchito a batire ya lithiamu. Ma heaters abwino (PTC) kapena makanema otenthetsera omwe ali ndi mphamvu ya 100-500 W/m² amaphatikizidwa ndi paketi. Makina otenthetsera amayendetsa pamene kutentha kwa ma cell kumatsika pansi pa 5 digiri, kuwononga 2-5% ya mphamvu ya paketi kuti isunge kutentha koyenera. Kutentha uku kumakhudza kwambiri kuti batire ya lithiamu imakhala nthawi yayitali bwanji pantchito zaulimi yozizira.
Kugwira Ntchito kwa Battery Management System
State Estimation Algorithms
Ma aligorivimu akuyerekeza amtundu wapamwamba amatsimikizira State of Charge (SOC) ndi State of Health (SOH) ya mapaketi a batri a lithiamu pogwiritsa ntchito njira zingapo.Kuwerengera kwa Coulombndi kukonza kwa Drift kumapereka kuyerekezera kofunikira kwa SOC, kolimbikitsidwa ndi Kusefa Kwawonjezedwa kwa Kalman kapena Kusefa Kwa Kalman Kosanunkhira kuti kukhale kolondola. Ma aligorivimu amaphatikiza mitundu yofananira yozungulira yokhala ndi ma RC angapo angapo kuti igwire ma batire mosiyanasiyana nthawi zosiyanasiyana.
Kuyerekeza kwa SOH kumagwiritsa ntchito kutha kwa mphamvu ndi kutsata kukula kwa kukana kudzera pakuwunika kwanthawi ndi nthawi ndi kuyeza kwa impedance. Makina ophunzirira makina, makamaka ma netiweki a Neural a Long Short-Term Memory (LSTM), amalosera mochulukira kuti batire ya lifiyamu imatha nthawi yayitali bwanji malinga ndi momwe kagwiritsidwe ntchito kake kakale komanso kuonongeka.
Njira Zosinthira Ma cell
Ma cell balancing systems amasamutsa mphamvu pakati pa ma cell pogwiritsa ntchito switched-capacitor or inductor-based topologies. Kusanja mafunde nthawi zambiri kumachokera ku 1-5A ndikuchita bwino kwa 85-95%. Algorithm yoyezera imayang'ana kusiyana kwamagetsi pansi pa 10mV pakati pa ma cell panthawi yopuma ndi 50mV panthawi yogwira ntchito. Kulinganiza kogwira mtima kumakulitsa moyo wa batire ya lithiamu poletsa kuwonongeka kwa selo payokha kuti lisachepetse magwiridwe antchito onse.
Njira Zolumikizirana
BMS imayang'anira paketi ya batri ya lithiamu ndikulumikizana ndi magawo owongolera magalimoto pogwiritsa ntchito ma protocol a CAN 2.0B kapena CAN FD pa baudrates ya 250-500 kbps. Zofunikira pauthenga zimatsata miyezo ya SAE J1939 ya zida zaulimi, zokhala ndi mauthenga ofunikira achitetezo omwe amaperekedwa patsogolo kwambiri. Njira zowunikira zimagwiritsa ntchito ISO 14229 (UDS) kapena SAE J1939-73 pothana ndi mavuto ndi kukonza.
Performance Optimization Strategy
Kukhathamiritsa Mbiri Yakale
Multi-stage CC-Maprotocol a CV amasintha mtengo wachaji kutengera kutentha ndi SOH, zomwe zimakhudza kwambiri moyo wautali wa batri.
• Gawo 1: mlingo wa 0.2-0.5C mpaka 20% SOC
• Gawo 2: mlingo wa 0.5-1C kuchokera ku 20-80% SOC
• Gawo 3: Kutsika kwapano kuchokera ku 80-100% SOC
Kuzama kwa Kasamalidwe ka Kutaya
Mawindo ogwiritsira ntchito nthawi zambiri amakhala ndi 10-90% SOC panjinga ya tsiku ndi tsiku, ndi zolipiritsa zanthawi zonse zowongolera.
Kuchepetsa DOD mpaka 70% kumatha kukhala moyo wozungulira kawiri poyerekeza ndi 100% ntchito ya DOD.
Regenerative Braking
Machitidwe amatsitsimutsa mphamvu ya kinetic panthawi ya braking ndikuyisunga mu lifiyamu batire paketi, ndi mphamvu pazipita regenerative kufika 50-100 kW kwa magalimoto lalikulu.
Kuwongolera moyenera kumachepetsa mphamvu zonse ndikuwonjezera moyo wa batri.
Ndife akatswiri opanga mabatire a zida zaulimi ndi ogulitsa ku China. Ngati mukufuna batire ya zida zaulimi zomwe zasinthidwa, talandiridwa kuti mudziwe zambiri kuchokera kufakitale yathu. Kuti tikambirane zamitengo, tilankhule nafe.
