Uburyo bwo kubara SOC

Soc ni iki?

Imiterere ya bateri (soc) nigipimo cyibisabwa ubungubu ubushobozi bwo kwishyuza, ubusanzwe bugaragazwa nkijanisha. Kubara neza so so ni ngombwa muri aSisitemu yo Gucunga Bateri (BMS)Nkuko bifasha kumenya ingufu zisigaye, gucunga imikoreshereze ya bateri, nakugenzura kwishyuza no gusezerera, bityo uzuze ubuzima bwa bateri.

Uburyo bubiri bwingenzi bukoreshwa mukubara SoU nuburyo bwo kwishyira hamwe nubu buryo bwa voltage yafunguye. Bombi bafite ibyiza byabo nibibi, kandi buriwese atangiza amakosa amwe. Kubwibyo, mubikorwa bifatika, ubu buryo bukunze guhuzwa no kunoza ukuri.

 

1. Uburyo bwo Kwishyira hamwe

Uburyo bwo Kwishyira hamwe bubabara so so muguhuza amafaranga yo kwishyuza no gusohora. Akarusho kayo iri mubworoshye bwabwo, ntabwo dusaba kalibration. Intambwe ni izi zikurikira:

1. Andika SoC mugitangira kwishyuza cyangwa kwirukana.
2. Gupima ikiriho mugihe cyo kwishyuza no kwirukana.
3. Guhuza ikigezweho kugirango ubone impinduka zishinzwe.
4. Kubara soc ukoresheje soc ya mbere hamwe nibisabwa bihinduka.

Formula ni:

SoC = soc yantangizo + q∫ (i⋅dt)

ahoNzabaho ubu, q nimbaraga za bateri, na dt nigihe gito.

Ni ngombwa kumenya ko kubera kurwanya imbere nibindi bintu, uburyo bwo kwishyira hamwe bufite urwego rwikosa. Byongeye kandi, bisaba igihe kirekire cyo kwishyuza no kurangiza kugirango ugere kubisubizo byukuri.

 

2. Uburyo bwumuzunguruko bwa voltiit

Uburyo bwumuzunguruko bwa voltiit (OCV) bubabara so so mugupima voltage ya bateri mugihe nta mutwaro. Ubworoherane bwarwo ninshuro nyamukuru nkuko bidasaba gupima ubu. Intambwe ni:

1. Shiraho umubano hagati ya Soc na OCV ukurikije imiterere ya bateri hamwe namakuru yabakora.
2. Gupima ocv ya bateri.
3. Kubara so sm ukoresheje umubano wa soc-ocv.

Menya ko socio-ocv yahinduye imikoreshereze ya bateri na lifespan, bisaba kalibration yigihe kugirango akomeze ukuri. Kurwanya imbere nabyo bigira ingaruka kuri ubu buryo, kandi amakosa afite akamaro karasuzuguro.

 

3. Guhuza uburyo bwo kwishyira hamwe na OCV

Kunoza ubunyangamugayo, ubufatanye nubu buryo bwa OCV bikunze guhuzwa. Intambwe Kuri Ubu buryo ni:

1. Koresha uburyo bwo kwishyira hamwe kugirango ukurikirane kwishyuza no kurangiza, kubona soc1.
2. Gupima ocv kandi ukoreshe umubano wa soc-ocv kugirango ubaze Soc2.
3. Huza soc1 na soc2 kugirango ubone soc.

Formula ni:

Soci = K1⋅soc1 + K2⋅soc2

ahoK1 na K2 ni coefficiere yuburemere ivuga kuri 1. Guhitamo coefficient bite bitewe no gukoresha bateri, igihe cyo kugerageza, no kumenya neza. Mubisanzwe, K1 nini cyane kugirango uremeke / gusohora ibizamini, na K2 ni binini kubipimo nyabyo bya OCV.

Calibration no gukosora birakenewe kugirango tumenye neza mugihe cyo guhuza uburyo, nkuko kurwanya imbere nubushyuhe nabyo bigira ingaruka kubisubizo.

 

Umwanzuro

Uburyo bwo Kwishyira hamwe nubu buryo bwa OCV nubuhanga bwibanze bwo kubara Sose, buri kimwe hamwe nuburenganzira bwacyo nibibi. Guhuza uburyo bworoshye birashobora kongera ukuri no kwizerwa. Ariko, kalibration no gukosora ni ngombwa muguhitamo so sonal opetion.
