Manyan hanyoyi guda biyu da ake amfani da su wajen ƙididdige SOC sune hanyar haɗaka ta yanzu da kuma hanyar wutar lantarki ta buɗe-wuri. Dukansu suna da fa'idodi da rashin amfaninsu, kuma kowannensu yana gabatar da wasu kurakurai. Saboda haka, a aikace-aikace, sau da yawa ana haɗa waɗannan hanyoyin don inganta daidaito.

 

1. Hanyar Haɗawa ta Yanzu

Hanyar haɗakarwa ta yanzu tana ƙididdige SOC ta hanyar haɗa kwararar caji da fitarwa. Fa'idarsa tana cikin sauƙinta, ba ta buƙatar daidaitawa. Matakan sune kamar haka:

1. Yi rikodin SOC a farkon caji ko fitarwa.
2. Auna wutar lantarki yayin caji da fitarwa.
3. Haɗa wutar lantarki don nemo canjin da ke caji.
4. Lissafa SOC na yanzu ta amfani da SOC na farko da canjin caji.

Tsarin shine:

SOC=SOC na farko+Q∫(I⋅dt)​

inaI shine wutar lantarki, Q shine ƙarfin baturi, kuma dt shine tazara tsakanin lokaci.

Yana da mahimmanci a lura cewa saboda juriya ta ciki da sauran dalilai, hanyar haɗakarwa ta yanzu tana da wani mataki na kuskure. Bugu da ƙari, tana buƙatar tsawon lokaci na caji da fitarwa don cimma sakamako mafi daidaito.

 

2. Hanyar Wutar Lantarki ta Buɗaɗɗen Da'ira

Hanyar wutar lantarki ta bude-da'ira (OCV) tana lissafin SOC ta hanyar auna ƙarfin batirin lokacin da babu kaya. Sauƙin sa shine babban fa'idarsa domin baya buƙatar aunawa ta yanzu. Matakan sune:

1. Kafa dangantaka tsakanin SOC da OCV bisa ga samfurin baturi da bayanan masana'anta.
2. Auna OCV na batirin.
3. Lissafa SOC ta amfani da alaƙar SOC-OCV.

Lura cewa lanƙwasa na SOC-OCV yana canzawa tare da amfani da batirin da tsawon rayuwarsa, yana buƙatar daidaitawa lokaci-lokaci don kiyaye daidaito. Juriyar ciki kuma tana shafar wannan hanyar, kuma kurakurai sun fi mahimmanci a yanayin fitarwa mai yawa.

 

3. Haɗa Haɗin Kai na Yanzu da Hanyoyin OCV

Domin inganta daidaito, galibi ana haɗa hanyoyin haɗin kai na yanzu da hanyoyin OCV. Matakan wannan hanyar sune:

1. Yi amfani da hanyar haɗin kai ta yanzu don bin diddigin caji da fitarwa, samun SOC1.
2. Auna OCV kuma yi amfani da alaƙar SOC-OCV don ƙididdige SOC2.
3. Haɗa SOC1 da SOC2 don samun SOC na ƙarshe.

Tsarin shine:

SOC=k1⋅SOC1+k2⋅SOC2

inaK1 da k2 ma'aunin nauyi ne da aka tattara zuwa 1. Zaɓin ma'aunin ya dogara da amfani da baturi, lokacin gwaji, da daidaito. Yawanci, k1 ya fi girma don gwaje-gwajen caji/fitarwa mai tsawo, kuma k2 ya fi girma don ma'aunin OCV daidai.

Ana buƙatar daidaitawa da gyara don tabbatar da daidaito yayin haɗa hanyoyin, saboda juriya ta ciki da zafin jiki suma suna tasiri sakamakon.

 

Kammalawa

Hanyar haɗa kai ta yanzu da kuma hanyar OCV sune manyan dabarun lissafin SOC, kowannensu yana da nasa fa'idodi da rashin amfani. Haɗa hanyoyin biyu na iya haɓaka daidaito da aminci. Duk da haka, daidaitawa da gyara suna da mahimmanci don tantance SOC daidai.
