Mugihe cyo gushushanya cyangwa kwagura sisitemu ikoreshwa na bateri, ikibazo rusange kivuka: Ese paki ebyiri za batiri zifite voltage imwe ishobora guhuzwa murukurikirane? Igisubizo kigufi niyego, ariko hamwe nibisabwa bikomeye:voltage ihangane nubushobozi bwumuzungurukobigomba gusuzumwa neza. Hasi, turasobanura amakuru ya tekiniki hamwe nubwitonzi kugirango tumenye neza umutekano kandi wizewe.
Gusobanukirwa Imipaka: Kurinda Umuzenguruko w'amashanyarazi
Amapaki ya batiri ya Litiyumu mubusanzwe afite ibikoresho byo kurinda umutekano (PCB) kugirango birinde kwishyurwa birenze, gusohora cyane, hamwe n’umuzunguruko mugufi. Urufunguzo rwibanze rwiyi PCB nivoltage kwihanganira igipimo cya MOSFETs zayo(ibyuma bya elegitoronike bigenzura imigendekere yubu).
Urugero:
Fata paki ebyiri za selile LiFePO4 nkurugero. Buri paki ifite voltage yuzuye ya 14.6V (3.65V kuri selile). Niba ihujwe murukurikirane, imbaraga zabo hamwe ziba29.2V. Ubusanzwe PCV irinda bateri PCB isanzwe ikorwa hamwe na MOSFETs yagenwe35-40V. Muri iki gihe, voltage yose (29.2V) igwa murwego rwumutekano, bigatuma bateri ikora neza murukurikirane.
Ingaruka zo Kurenga Imipaka:
Ariko, uramutse uhujije paki enye murukurikirane, voltage yose yarenga 58.4V - birenze kure kwihanganira 35-40V ya PCBs zisanzwe. Ibi bitera akaga kihishe:
Siyanse Yihishe inyuma
Iyo batteri ihujwe murukurikirane, voltage zabo ziyongera, ariko imiyoboro yo gukingira ikora yigenga. Mubihe bisanzwe, voltage ihujwe iha imbaraga umutwaro (urugero, igikoresho cya 48V) ntakibazo. Ariko, nibaipaki imwe ya batiri itera kurinda.
Kuri iyi ngingo, voltage yuzuye ya bateri zisigaye murukurikirane zikoreshwa hakurya MOSFETs zaciwe. Kurugero, mubice bine bipakiye, PCB itandukanijwe ishobora guhura hafi58.4V-Kurenza igipimo cyayo 35-40V. MOSFETs irashobora noneho kunanirwa kuberakumeneka, guhagarika burundu uruzinduko rwo kurinda no gusiga bateri ishobora guhura nibibazo bizaza.
Ibisubizo byumutekano uhuza
Kugira ngo wirinde izo ngaruka, kurikiza aya mabwiriza:
1.Reba ibicuruzwa byakozwe:
Buri gihe ugenzure niba PC yawe ikingira PCB yagenwe kubisabwa. PCB zimwe zashizweho kuburyo bugaragara kugirango zikoreshe voltage nyinshi muburyo butandukanye.
2.Custom Custom-Voltage PCBs:
Kubikorwa bisaba bateri nyinshi murukurikirane (urugero, kubika izuba cyangwa sisitemu ya EV), hitamo imiyoboro yo gukingira hamwe na MOSFETs yihariye. Ibi birashobora guhuzwa kugirango bihangane na voltage yuzuye ya seriveri yawe.
3.Igishushanyo mbonera:
Menya neza ko paki zose za batiri murukurikirane zahujwe nubushobozi, imyaka, nubuzima kugirango ugabanye ingaruka ziterwa nuburyo butemewe bwo kurinda.
Ibitekerezo byanyuma
Mugihe guhuza bateri imwe ya voltage murukurikirane birashoboka tekiniki, ikibazo nyacyo kiri mukureba kokurinda umuziki birashobora gukemura ibibazo bya voltage. Mugushira imbere ibice byihariye nibishushanyo mbonera, urashobora gupima neza sisitemu ya bateri ya progaramu ya voltage nyinshi.
Kuri DALY, turatangabyihariye PCB ibisubizohamwe na voltage nyinshi MOSFETs kugirango ihuze urwego rukomeye-ihuza ibikenewe. Menyesha itsinda ryacu kugirango ushushanye sisitemu yingufu zizewe, zizewe kumishinga yawe!
