LiFePO4 BMS yasobanuwe: Uburyo bwo guhitamo ikwiye (2026)

Bateri ya LiFePO4 idafite BMS ni inshingano idasubirwaho.
Igikorwa kimwe cyo kongera imbaraga gishobora gusenya burundu uturemangingo. BMS itari yo
bitera amezi menshi yo kugabanya ubushobozi bw'umuntu no gutakaza ubushobozi. Iyi nyandiko iyobora
ikubiyemo byose ukeneye kugira ngo ufate icyemezo gikwiye.

BMS ikora imirimo itatu icyarimwe:

Uburinziigabanya urujya n'uruza rw'amashanyarazi mu gihe ingirabuzimafatizo iyo ari yo yose irengeje idirishya ryayo ryizewe - umuriro uri hejuru ya 3.65 V/ingirabuzimafatizo, usohoka uri munsi ya 2.8 V/ingirabuzimafatizo (urugero rwemewe rw'imikorere), cyangwa iyo imiterere y'umuvuduko w'amashanyarazi, ubushyuhe, cyangwa imiterere y'urujya n'uruza rw'amashanyarazi ibaye akaga.

Kuringanizaikosora ingendo isanzwe hagati y’uturemangingo mu gihe cy’ingendo amagana. Iyo idahari, uturemangingo twawe dufite intege nke cyane ni two dusobanura ubushobozi bwose bw’ipaki yawe - kandi tugatakaza agaciro vuba cyane.

Gukurikiranaikurikirana imiterere y'umushari (SOC), imiterere y'ubuzima (SOH), voltage kuri buri selile, ubushyuhe, n'umubare w'ingendo mu gihe nyacyo. Aya makuru agufasha gufata selile yangiritse mbere yuko ifata ipaki.

Uburyo bwihariye bwo gusohora amazi bwa LiFePO4 busaba BMS yihariye ya chimie. BMS isanzwe ikoresha SOC nabi mu gice cyose cy’ubutaka kandi igatera gucika kw’amashanyarazi make ku buryo butari bwo, hagasigara ubushobozi bunini.

Uburyo bwo gupima BMS yawe

Ibisobanuro bibiri bigomba kuba bihuye neza n'ipaki yawe.

Intambwe ya 1 — Voltage (umubare w'uturemangingo tw'uruhererekane).Paki ya 4S ikenera BMS ya 4S. Paki ya 16S ikenera BMS ya 16S. Ingirabuzimafatizo imwe ihagarika ikoreshwa nabi mu mikorere y'amashanyarazi ndetse n'uburinzi budasobanutse.

Intambwe ya 2 - Iy'ubu.Gabanya umutwaro wawe ntarengwa uhoraho muri watts ukoresheje voltage ya paki, hanyuma wongereho 25–30% by'umutekano.

5,000 W ÷ 48 V = 104 A → Hitamo 150 A BMS

Ntuzigere ukoresha BMS ku kigero cya 100% cy'umuvuduko wayo. Gutakaza ubushyuhe n'umuvuduko w'amashanyarazi buri gihe bituma icyifuzo cy'ibintu nyabyo kirenga umubare wabazwe.

Kugereranya ibikorwa ugereranije n'ibidakora

Kuringaniza ibintu mu buryo budakoraIpfusha ubusa umuriro urenze urugero nk'ubushyuhe binyuze muri resistor (50–200 mA). Ituma udupaki duhuye neza ariko ntishobora kugarura uburyohe bukomeye bw'uturemangingo - gukosora ikibazo cy'ubusumbane bwa 500 mA bifata amasaha agera kuri 5 kuri 100 mA.

Kuringaniza nezaYohereza ingufu hagati y’uturemangingo binyuze mu buryo bwa inductor-capacitor (1–5 A, 80–95%). Ikosora ubusumbane bwa 10–50× vuba kandi ikora mu gihe cyose cyo gutanga umuriro wose no gusohora, atari hejuru gusa.

Hitamo kudakoresha uburyo bwa "passive"ku turemangingo tw’itsinda rimwe twazungurutse kuri ≤ 0.3C.
Hitamo ikoraku mapaki ≥ 200 Ah, igipimo cyo gusohora kiri hejuru ya 0.5C, cyangwa utunyangingo duturutse mu matsinda avanze.

Urutonde rw'ibipimo bine byo guhitamo

Mbere yo gutumiza, genzura ibipimo bine byose icyarimwe:

Ibikoresho bya DALY Energy BMS bigizwe na 4S kugeza kuri 24S na 10 A kugeza kuri 500 A, mu buryo busanzwe, bwa smart (Bluetooth + RS485 / CAN), na active balance configurations — byose byoherezwa hamwe na LFP chemistry thresholds ku buryo busanzwe.
