Gusobanukirwa itandukaniro riri hagati yo kurwanya imbere ningirakamaro nimbogamizi kubantu bose bakorana na bateri ya UPS, sisitemu ya BMS, cyangwa amashanyarazi. Mugihe bikunze gukoreshwa muburyo bumwe, byerekana muburyo butandukanye amashanyarazi - imwe kumuzunguruko wa DC, indi ya AC. Aka gatabo gatanga igereranya ryumvikana, tekinike ningaruka zifatika zo gukurikirana bateri.
Kurwanya imbere ni ukurwanya gutembera kwimbere muri bateri iyo hashyizweho umuyoboro utaziguye (DC). Bituruka kumurwanya wa electrolyte, electrode, hamwe nimbere. Kurwanya imbere ni umubare nyawo (urugero, 5.3 mΩ) kandi ntabwo uhinduka hamwe numurongo. Nibimwe mubimenyetso byingenzi byubuzima bwa bateri - kwiyongera kwimbere imbere akenshi byerekana sulfation, ruswa ya gride, cyangwa gutakaza ubushobozi.
Impedance ni opozisiyo yuzuye yo guhinduranya amashanyarazi (AC) mukuzunguruka. Harimo kurwanya byombi (igice nyacyo) hamwe na reaction (igice cyibitekerezo, uhereye kuri capacitance na inductance). Impedance iterwa ninshuro kandi igaragazwa nkumubare utoroshye (R + jX). Mugukurikirana bateri, ibipimo bya AC impedance bikoreshwa mugusuzuma ibiranga imbere utarangije bateri.
Imbonerahamwe 1: Itandukaniro ryibanze hagati yo kurwanya imbere (DC) na impedance (AC) mubuhanga bwamashanyarazi.
| Ibice byumutungo wamashanyarazi | Kurwanya Imbere (R) | Impedance (Z) |
|---|---|---|
| Gusaba Inzira | Byakoreshejwe cyane cyane mumuzunguruko ukorera kumurongo utaziguye (DC). | Ahanini ikoreshwa mumuzunguruko wagenewe guhinduranya amashanyarazi (AC). |
| Kubaho | Biraboneka muburyo bwombi busimburana (AC) hamwe nubuyobora (DC). | Wihariye guhinduranya imirongo (AC), ntabwo ihari muri DC. |
| Inkomoko | Bikomoka kubintu bibuza umuvuduko w'amashanyarazi. | Bituruka ku guhuza ibintu birwanya kandi bigira ingaruka kumashanyarazi. |
| Imibare | Byerekanwe ukoresheje imibare nyayo, urugero, 5.3 mΩ. | Byerekanwa binyuze mumibare nyayo nibigize ibitekerezo, byerekanwe na R + jX. |
| Kwishingikirizaho | Agaciro kayo kaguma gahoraho hatitawe kumurongo wa DC ya none. | Agaciro kayo gahindagurika hamwe nimpinduka zumurongo wa AC. |
| Icyiciro kiranga | Ntabwo yerekana icyiciro icyo aricyo cyose cyangwa ubunini buranga. | Kurangwa na fonctionnement yicyiciro nubunini. |
| Imyitwarire mumashanyarazi | Yerekana gusa imbaraga zo gukwirakwiza iyo zihuye numuriro wa electroniki. | Yerekana imbaraga zombi zikwirakwizwa nubushobozi bwo kubika ingufu mumashanyarazi. |
Muri sisitemu ya kijyambere yo gucunga bateri (BMS), haba harwanya imbere ndetse nimbogamizi bikurikiranwa kugirango hubakwe ishusho yuzuye yubuzima bwa bateri. Kwiyongera kwimbere imbere ni umuburo hakiri kare wo kwangirika, mugihe impedance spectroscopy ishobora kwerekana impinduka zimiti imbere. DFUN BMS ikoresha uburyo bwa AC bwo gupima neza kugirango ikurikirane imigendekere yo kurwanya imbere no kumenya ibintu bidasanzwe mbere yuko biganisha ku gutsindwa.
BMS ya DFUN ikoresha umurongo uhoraho wa AC kuri buri selire ya batiri kandi igapima kugabanuka kwa voltage. Kurwanya imbere kubarwa ukoresheje amategeko ya Ohm, hamwe nukuri ± 1-2%. Ubu buryo ntabwo - butera, ntibusaba guhagarika bateri, kandi butanga amakuru nyayo yo kubungabunga ibintu.
Imbere yo kurwanya imbere (R) numutungo wa DC urwanya urujya n'uruza, mugihe impedance (Z) numutungo wa AC urimo kurwanya no kubyitwaramo.
Kuzamuka kwimbere imbere ni kimwe mubimenyetso byambere byerekana kwangirika kwa bateri, sulfation, no gutakaza ubushobozi.
DFUN BMS ikoresha uburyo bwihuse bwa AC bwo gutera inshinge kugirango bapime imbere imbere hamwe na 1-2% byukuri, bitabangamiye imikorere ya bateri.
