Recommendations for Parallel Charging LiFePO4

• Ita shuwa kuti mabhatiri ndeemhando imwe chete, mhando, uye saizi.
• Paunenge uchibatanidza mabhatiri eLiFePO4 akafanana, ita shuwa kuti musiyano wevoltage pakati pebhatiri rega rega haupfuure 0.1V.
• Ita shuwa kuti urefu hwetambo hwese uye saizi yekubatanidza zvakafanana kuti ive nechokwadi chekuramba kwemukati.
• Paunenge uchichaja mabhatiri pamwe chete, iyo yekuchaja ikozvino kubva kusimba rezuva inopetwa nepakati, nepo huwandu hwekuchaja hunowedzera kaviri.

Recommendations for Series Kuchaja LiFePO4

• Usati wachaja nhevedzano, ita shuwa kuti bhatiri rega rega nderemhando imwechete, mhando, uye huwandu.
• Kana uchibatanidza mabhatiri eLiFePO4 munhevedzano, ita shuwa kuti musiyano wevoltage pakati pebhatiri rega rega haupfuure 50mV (0.05V).
• Kana paine kusaenzana kwebhatiri, uko chero simba rebhatiri rinosiyana nekupfuura 50mV (0.05V) kubva kune mamwe, bhatiri rega rega rinofanira kuchajwa rakaparadzana kuti rienzane.

Safe Kuchaja Mazano eLiFePO4

• Dzivisa Kuwedzeresa uye Kuwedzeresa-Kubvisa: Kuti udzivise kutadza kwebhatiri nguva isati yakwana, hazvifanirwe kubhadharisa zvizere kana kuburitsa zvizere LiFePO4 mabhatiri.Kuchengeta bhatiri pakati pe20% ne80% SOC (State of Charge) itsika yakanakisa, kuderedza kushushikana kwebhatiri uye kuwedzera hupenyu hwayo.
• Sarudza Chaja Chakakodzera: Sarudza charger yakanyatsogadzirirwa LiFePO4 mabhatiri kuti ive nechokwadi chekuenderana uye kunyatsochaja kuita.Isa pamberi machaja ane anogara aripo uye anogara achichaja magetsi ekuchaja kwakadzikama uye kwakanaka.

Chengetedzo Yekuchengetedza Panguva yekuchaja

• Nzwisisa Zvekuchengetedza Zvekuchaja Equipment: Gara uine shuwa kuti magetsi ekuchaja uye zvazvino zviri mukati merudzi rwakakurudzirwa nemugadziri webhatiri.Shandisa machaja ane dziviriro dzakawanda dzekuchengetedza, senge overcurrent protection, overheating dziviriro, uye short-circuit dziviriro.
• Dzivisa Mechanical Kukuvadza Panguva yekuchaja: Ita shuwa kuti majoisheni ekuchaja akachengeteka, uye dzivirira kukuvadzwa kwemuviri kuchaja nebhatiri, sekudonha, kudzvanya, kana kukotama zvakanyanya.
• Dzivisa Kuchaja muTembiricha Yakanyanya kana Humid Conditions: Tembiricha yepamusoro uye nharaunda dzine hunyoro zvinogona kukuvadza bhatiri uye kuderedza kuchaja kunyatsoita.

Kusarudza Chaja Chakakodzera

• Nzira Yekusarudza Charger Inokodzera LiFePO4 Mabhatiri: Sarudza charger inogara iripo uye inongogara voltage yekuchaja masimba, uye inogadziriswa ikozvino uye voltage.Uchifunga zvaunoda pakunyorera, sarudza mwero wakakodzera wekuchaja, kazhinji mukati meiyo 0.5C kusvika 1C.
• Kufananidza Charger Yazvino uye Voltage: Ita shuwa kuti kubuda uye voltage yechaja inoenderana nekurudziro yemugadziri webhatiri.Shandisa majaja ane zvazvino uye voltage kuratidza mabasa kuti iwe ugone kutarisa maitiro ekuchaja munguva chaiyo.

Maitiro Akanyanya Kuchengeta LiFePO4 Mabhatiri

• Gara uchitarisa Mamiriro eBattery uye Kuchaja Equipment: Nguva nenguva tarisa magetsi ebhatiri, tembiricha, uye chitarisiko, uye ona kuti midziyo yekuchaja iri kushanda nemazvo.Ongorora mabhatiri ekubatanidza uye insulation layer kuti uone kuti hapana kupera kana kukuvara.
• Mazano ekuchengeta Mabhatiri: Paunenge uchichengeta mabhatiri kwenguva yakareba, zvinokurudzirwa kuchaja bhatiri kusvika ku50% kugona uye kuachengeta munzvimbo yakaoma, inotonhorera.Gara uchitarisa chiyero chebhatiri uye recharge kana zvichidikanwa.

LiFePO4 Temperature Compensation

LiFePO4 mabhatiri haadi voltage tembiricha muripo kana uchichaja pane yakakwirira kana yakaderera tembiricha.Ese mabhatiri eLiFePO4 ane akavakirwa-mukati Battery Management System (BMS) inodzivirira bhatiri kubva pamhedzisiro yekudzika uye yakakwirira tembiricha.

Kuchengetedza uye Kuchengetedza Kwenguva Yakareba

Yenguva Yakareba Storage Recommendations

• Battery State of Charge: Paunenge uchichengeta LiFePO4 mabhatiri kwenguva yakareba, zvinokurudzirwa kuchaja bhatiri kusvika ku50%.Iyi mamiriro anogona kudzivirira bhatiri kuti risabudiswe zvakazara uye kuderedza kushushikana kwekuchaja, nekudaro kuwedzera hupenyu hwebhatiri.
• Nzvimbo Yekuchengetedza: Sarudza nzvimbo yakaoma, inotonhorera yekuchengetedza.Regedza kuisa bhatiri kune tembiricha yakakwira kana hunyoro mamiriro, izvo zvinogona kukanganisa kushanda kwebhatiri uye hupenyu.
• Kuchaja nguva dzose: Panguva yekuchengetedza kwenguva refu, zvinokurudzirwa kuita mari yekugadzirisa pabhatiri mwedzi yese ye3-6 kuchengetedza bhatiri kubhadharisa uye hutano.

Kutsiva Akavharwa Lead-Acid Mabhatiri neLiFePO4 Mabhatiri muFloat Application.

• Self-discharge Rate: LiFePO4 mabhatiri ane yakaderera self-discharge rate, zvichireva kuti vanorasikirwa shoma mutero panguva yekuchengetedza.Kuenzaniswa nemabhatiri e-lead-asidhi akavharidzirwa, anonyatsokodzera kushandiswa kwenguva refu kwekuyangarara.
• Cycle Life: Upenyu hwemabhatiri eLiFePO4 hunowanzorebesa kupfuura hwemabhatiri e-lead-acid akavharwa, zvichiita kuti ive sarudzo yakanaka yezvikumbiro zvinoda simba rinovimbika uye rakasimba.
• Kuita Kugadzikana: Kuenzaniswa nemabhatiri akavharidzirwa e-lead-acid, mabhatiri eLiFePO4 anoratidza kushanda kwakasimba pasi pekushisa kwakasiyana uye mamiriro ezvakatipoteredza, zvichiita kuti zvive zvakanaka kune zvakasiyana-siyana zvekushandisa, kunyanya munzvimbo dzinoda kushanda kwepamusoro uye kuvimbika.
• Mutengo-kubudirira: Kunyange zvazvo mari yekutanga yeLiFePO4 mabhatiri ingave yakakwirira, tichifunga nezvehupenyu hwavo hurefu uye pasi pekugadzirisa zvinodiwa, ivo vanowanzove vane mari yakawanda munguva refu.
