Iibhetri ze-Lithium iron phosphate (LiFePO4) ziza kwiphakheji enye enamandla amaninzi kunye nexabiso. Le chemistry yebhetri ye-lithium yinxalenye enkulu yokusebenza kwayo okuphezulu. Ngelixa zonke iibhetri ze-lithium-ion ezidumileyo zikwabandakanya elinye icandelo elibalulekileyo kunye neeseli zebhetri: inkqubo yolawulo lwebhetri eyilwe ngononophelo (BMS). Inkqubo yokulawula ibhetri eyilwe kakuhle inokukhusela kakhulu kwaye ibeke iliso kwibhetri ye-lithium-ion ukunyusa ukusebenza, ukwandisa ixesha lokuphila, kunye nokuqinisekisa ukusebenza okukhuselekileyo kwiintlobo ezininzi zokusetyenziswa kweemeko.

Ngaphezulu kokuKhuselwa kweVolthi
Iiseli ze-LiFePO4 zisebenza ngokukhuselekileyo kuluhlu lwee-voltages, ngokuqhelekileyo ukusuka kwi-2.0V ukuya kwi-4.2V. Ezinye iikhemistri ze-lithium zikhokelela kwiiseli ezinobuthathaka kakhulu kwi-over-voltage, kodwa iiseli ze-LiFePO4 zinyamezela ngakumbi. Nangona kunjalo, i-voltage ebaluleke kakhulu ixesha elide ngexesha lokutshaja kunokubangela ukugcwala kwe-metallic lithium kwi-anode yebhetri ethoba ngokusisigxina ukusebenza. Kwakhona, izinto ze-cathode zinokuthi zifake i-oxidize, zizinzile, kwaye zivelise i-carbon dioxide enokuthi ikhokhelele kwi-buildup yoxinzelelo kwiseli. I-Polinovel BMS ikhawulela iseli nganye kunye nebhetri ngokwayo kumbane ophezulu we-3.9V kunye ne-15.6V.

Ngaphantsi koKhuseleko lwe-Voltage
I-Under-voltage ngexesha lokukhutshwa kwebhetri ikwayinkxalabo kuba ukukhupha iseli ye-LiFePO4 engaphantsi malunga ne-2.0V kunokubangela ukophuka kwezinto ze-electrode. I-BMS isebenza njengentsilelo-ekhuselekileyo yokukhupha ibhetri kwisiphaluka ukuba nayiphi na iseli yehla ngaphantsi kwe-2.0V. Iibhetri ze-lithium ze-Polinovel zine-voltage yokusebenza ecetyiswayo encinci, eyi-2.5V yeeseli, kunye ne-10V yebhetri.

Ukhuseleko lwangoku
Ibhetri nganye inobuninzi obuchaziweyo bangoku bokusebenza ngokukhuselekileyo. Ukuba umthwalo otsala umsinga ophezulu kwi-batter, unokubangela ukutshisa ibhetri. Nangona kubalulekile ukusebenzisa ibhetri ngendlela yokugcina umzobo wangoku ungaphantsi kowona mlinganiselo mkhulu, i-BMS iphinda isebenze njenge-backstop ngokuchasene neemeko zangoku kwaye ikhuphe ibhetri kwisekethe.

Ukukhuselwa kweSekethe emfutshane
Isiphaluka esifutshane sebhetri yeyona ndlela inzima kakhulu yemeko yangoku. Ngokuqhelekileyo kwenzeka xa i-electrodes idibaniswe ngengozi kunye neqhekeza lesinyithi. I-BMS kufuneka ikhangele ngokukhawuleza imeko yesiphaluka esifutshane phambi kokuba umzobo wequbuliso kunye nomkhulu wangoku ugqithise ibhetri kwaye ibangele umonakalo omkhulu.

Ngaphezulu kwamaqondo obushushu
Iibhetri zeLithium iron phosphate zisebenza ngokufanelekileyo nangokukhuselekileyo kumaqondo obushushu ukuya kuma 60oC nangaphezulu. Kodwa kwiqondo lokushisa eliphezulu lokusebenza kunye nokugcinwa, njengazo zonke iibhetri, izinto ze-electrode ziya kuqala ukuthotywa. I-BMS yebhetri ye-lithium isebenzisa i-thermistors edibeneyo ukujonga ubushushu ngexesha lokusebenza, kwaye iya kukhupha ibhetri kwisiphaluka kwiqondo lokushisa elichaziweyo.

isishwankathelo
Iibhetri zeLithium iron phosphate zakhiwe ngeeseli nje ezidityaniswe kunye. Zikwabandakanya inkqubo yokulawula ibhetri (BMS) engabonakaliyo kumsebenzisi wokugqibela, ukuqinisekisa ukuba iseli nganye kwibhetri ihlala ngaphakathi kwemida ekhuselekileyo. Kwi-JB BATTERY, zonke iibhetri zethu ze-LiFePO4 ziquka i-BMS yangaphakathi okanye yangaphandle ukukhusela, ukulawula, nokubeka iliso kwibhetri ukuqinisekisa ukhuseleko kunye nokwandisa ixesha lokuphila phezu koluhlu olupheleleyo lweemeko zokusebenza.
