Incamake y'Ubuyobozi

Iyi mfashanyigisho ikubiyemo sisitemu zubatswe mu mapaki menshi ya bateri ya lithium yigenga, aho umusaruro wayo uba uhujwe na bisi isanzwe ya DC. Ntitwikira utunyangingo duhujwe mu buryo buhuriweho imbere muri paki imwe ya bateri.

1. Sobanura icyo ari cyo cyose gihuzwa muri parallel

Sisitemu isanzwe ishobora gukoresha Paki ya 1 ifite uburyo bwayo bwo kugenzura no kurinda ipaki, Paki ya 2 ifite uburyo bwayo bwo kugenzura no kurinda ipaki, hamwe n'izindi paki zigenga zihujwe na bisi isanzwe ya DC. Imiterere ya nyuma yo kurinda no kugenzura igomba kwemezwa kuri sisitemu yihariye ya bateri.

Mbere yo gusuzuma BMS, banza usobanure umubare w'amapaki yigenga, uburyo azahuzwa, niba amapaki ashobora kongerwamo cyangwa gukurwaho mu gihe cy'ikoreshwa, ndetse n'ibikoresho bihujwe na bisi isanzwe ya DC.

2. Ntugabanye igipimo cy'umuvuduko w'amashanyarazi n'ingano y'ipaki

Niba sisitemu ya 300A ikoresha bateri eshatu, kugabanya 300A na eshatu ntabwo bigaragaza ko buri paki izahora ifite 100A neza. Isaranganya rigezweho rishobora guhinduka bitewe n'ubudahangarwa bw'ipaki, imiterere y'umuriro, ubushyuhe, ubudahangarwa bw'insinga, ubudahangarwa bw'ihuza n'imiyoboro y'amashanyarazi.

Tobora BMS kuri buri paki ukurikije amashanyarazi yitezweho. Emeza ko umuriro uhoraho ugana ku ruhande rwa bateri, umuriro ugera ku rwego rwo hejuru, igihe ugera ku rwego rwo hejuru, inshuro zisubiramo n'imiterere y'ubushyuhe ikikije BMS.

3. Emeza ko ipaki ihuye mbere yo guhuza

Paki zigenga zigenewe gukoreshwa icyarimwe zigomba kugenzurwa mbere yo guhuza. Itandukaniro riri hagati y’amapaki rishobora kugira ingaruka ku gusangira ubushyuhe kandi rishobora no gutuma ubushyuhe bukwirakwira hagati y’amapaki iyo ahujwe.

• Ubutabire bwa bateri
• Umubare nyawo w'uturemangingo tw'uruhererekane (umubare wa S)
• Umuvuduko w'amashanyarazi mu ipaki
• Ubushobozi
• Leta y'ikurikiranacyaha (SOC)
• Imiterere ya batiri n'imyaka aho bikenewe
• Ubushyuhe bwo gukora

Iyo amapaki ahujwe ku muvuduko cyangwa imiterere itandukanye y'amashanyarazi, umuvuduko w'amashanyarazi ushobora gutembera hagati y'amapaki ari mu muvuduko. Emeza imiterere yemewe y'umuvuduko w'amashanyarazi n'ingamba zose zisabwa zo kugabanya umuvuduko w'amashanyarazi cyangwa kurinda umuvuduko w'amashanyarazi mbere yo guhuza amapaki.

4. Emeza ubushobozi bungana nk'ibisabwa bitandukanye

BMS ifite shimi ikwiye, umubare w’uruhererekane n’ibipimo by’ubu ntabwo ikwiriye mu buryo bwikora kuri sisitemu ikora ibintu byinshi. Imikorere ikora kimwe igomba kwemezwa kugira ngo hamenyekane neza uko BMS n’imiterere y’umushinga bimeze.

Emeza niba imiterere yatoranijwe isaba module itandukanye cyangwa indi solution ijyanye n'ubushobozi, umubare w'udupaki dushyigikira imiterere nyayo, imiterere y'amashanyarazi cyangwa imiterere y'amashanyarazi ikurikizwa mbere yo guhuza, ndetse niba hari imikorere yo kugabanya cyangwa kurinda umuriro ikenewe.

5. Emeza Ibisabwa mu Itumanaho ukwaryo

Niba sisitemu ya bateri ikeneye guhanahana amakuru na inverter, controller, charger, ecran cyangwa ibindi bikoresho, tanga icyitegererezo cy'ibikoresho byibandwaho hamwe na protocole y'itumanaho ikenewe.

Kugira uburyo bwo gutumanaho ubwabyo ntibisobanura ko ibice byinshi bya BMS bizahuza cyangwa bikavugana neza n'ibikoresho byagenewe. Imyitwarire n'amabwiriza bisabwa bya sisitemu bigomba kwemezwa ku mushinga.

6. Icyo wohereza DALY kuri Parallel-Battery BMS Selection

Kugira ngo usuzume umushinga wa bateri isa n'iyakoreshejwe, tanga amakuru akurikira:

Hamwe n'ibi bitekerezo, itsinda rya tekiniki rya DALY rishobora gusuzuma imiterere ikwiye ya BMS, kwemeza niba hakenewe module parallel cyangwa indi imiterere ijyanye n'imikorere parallel, kugenzura imiterere ijyanye n'imikoranire, no gutanga amakuru ajyanye n'ibicuruzwa n'ibiciro.

Ibibazo Bikunze Kubazwa

Q1Ese hari bateri ebyiri za lithium zirinda BMS zishobora guhuzwa icyarimwe?

Oya. Paki za bateri, imiterere ya BMS n'imiterere y'ihuza bigomba kugenzurwa kugira ngo harebwe sisitemu yihariye ijyanye nayo mbere yo kuyihuza.

Q2Niba udupaki dutatu dutanga sisitemu ya 300A, buri gapaki ikeneye BMS ya 100A gusa?

Si ngombwa. Umuriro ushobora kudatandukana kimwe hagati y’amapaki. Tora buri BMS ugereranije n’umuriro witezwe w’iyo paki, harimo n’umuriro uhoraho n’uw’umubare munini w’amashanyarazi, kandi utekereze ku mikoreshereze y’umuriro n’ubushyuhe.

Q3Ese voltage ikwiye n'igipimo cy'amashanyarazi bivuze ko BMS ishyigikira imikorere ijyanye n'igihe?

Oya. Ubushobozi bwo gukoresha uburyo bunyuranye ni ngombwa mu buryo butandukanye. Emeza imiterere nyayo ya BMS, module iyo ari yo yose ikenewe, imiterere y’ikoranabuhanga n’imiterere y’itumanaho.

Q4Ese CAN cyangwa izindi mbuga z'itumanaho bivuze ko ibice byinshi bya BMS bizahuza mu buryo bwikora?

Oya. Interineti yonyine ntabwo isobanura imyitwarire ya sisitemu isabwa cyangwa protocole y'ubutumwa. Emeza ibisabwa mu itumanaho ku mushinga nyawo.

Saba Isuzuma rya BMS yo Guhitamo Bateri Ingana

Ohereza DALY imiterere y'ipaki yawe, umubare w'amapaki, uburyo bwo kuyihuza, ibisabwa kuri buri paki, imiterere y'ihuza n'ibindi byose bisabwa na inverter, charger cyangwa itumanaho.

Itsinda rya tekiniki rya DALY rishobora gusuzuma imiterere y’ibikoresho bihuye, rigashaka BMS ikwiye n’igisubizo gihuye, kandi rigatanga inyandiko n’ibiciro by’ibicuruzwa bihuye.
