Kuita kuti Arrays Ishande Yechikumbiro Chako
Battery arrays anobudirira kana akagadzirirwa zvinodiwa kwete zvegeneric. Imba yesolar system inoda akasiyana array maitiro pane yemagetsi mota kana grid yekuchengetera nzvimbo.
Tanga nekutsanangura matatu ma paramita: inodiwa voltage, inodiwa huwandu, uye discharge profile. A 48V solar system inoda mabhatiri akagadzirirwa kuti abudise 48V nominal. Kana uchida 10 kWh yekuchengetedza, patsanura nemagetsi: 10,000 Wh ÷ 48V=208 Ah inodiwa.
Tevere, sarudza akakodzera maseru kutsanangurwa. Yakajairwa 12V lithium mabhatiri anouya mune masimba kubva pa50Ah kusvika 200Ah. Mabhatiri mana e12V 52Ah akateedzana anogadzira 48V 52Ah (2.5 kWh). Kuti usvike 10 kWh, unoda tambo ina dzakafanana dzemabhatiri mana akatevedzana-mabhatiri gumi nematanhatu akazara mu4s4p kumisikidzwa.
Funga nezvemitengo yekubuda. Kana application yako ichida 5 kW peak power, array yacho inofanira kuunza 5000W ÷ 48V=104A. Imwe neimwe 4s tambo inopa bhatiri imwe ikozvino chiyero. Kana bhatiri rimwe nerimwe riine 50A rinoramba richibuda, unoda chete tambo nhatu dzakafanana, kwete ina. Mutsara waizove 4s3p nemabhatiri gumi nemaviri.
Kutarisira tembiricha kunowanzo tara kubudirira kana kukundikana. Mabhatiri anoita zvisina kunaka pazasi 0 dhigirii uye kuderera nekukurumidza pamusoro pe40 degree. Zvishandiso zvinoshanda kunze zvinoda kudziyisa munzvimbo dzinotonhora uye kutonhora mune dzinopisa. Kunyangwe maapplication ari pakati nepakati anobatsirwa kubva kune insulated enclosures uye mhepo inochengetedza 15-25℃.
Chengetedza masisitimu zvakanyanya panguva yekutanga kushanda. Cell voltage Drift mumavhiki ekutanga inoratidza kusawirirana kwekugadzira. Gadzirisa kusaenzana nekukasira kuburikidza nekutsiviwa kwesero kana kushanda kuenzanisa pane kurega maseru asina kusimba achikanganisa mashandiro akarongeka.
Iyo modularity yebhatiri arrays ndiro simba radzo guru. Iwe unogona kutanga zvidiki uye kuwedzera nekuwedzera, uchiwedzera tambo dzakafanana dzekuwedzera huwandu kana tambo dzakatevedzana dzepamusoro voltage. Iyi scalability inoita kuti arrays awane hupfumi kunyangwe kune maapplication anogona kukura nekufamba kwenguva.
