Isishwankathelo seSikhokelo

Esi sikhokelo sigubungela iinkqubo ezakhiwe ngeepakethi ezininzi zebhetri ye-lithium ezizimeleyo apho iziphumo zazo ziqhagamshelwe kwibhasi eqhelekileyo ye-DC. Asigqumi iiseli eziqhagamshelwe ngaxeshanye ngaphakathi kwepakethi enye yebhetri.

1. Chaza ukuba yintoni edityanisiweyo kwi-Parallel

Inkqubo eqhelekileyo ingasebenzisa iPack 1 enokubeka esweni nokukhusela kwinqanaba lepakethi, iPack 2 enokubeka esweni nokukhusela kwinqanaba lepakethi, kunye nezinye iipakethi ezizimeleyo eziqhagamshelwe kwibhasi eqhelekileyo yeDC. Uyilo lokugqibela lokukhusela nokulawula kufuneka luqinisekiswe kwinkqubo ethile yebhetri.

Ngaphambi kokuba uvavanye i-BMS, chaza inani leepakethe ezizimeleyo, indlela eziza kudityaniswa ngayo, nokuba iipakethe zingongezwa okanye zisuswe na ngexesha lokusebenza, kunye nezixhobo ezidityaniswe kwibhasi eqhelekileyo ye-DC.

2. Musa Ukwahlula i-Total System Current ngobuninzi bePakethi

Ukuba inkqubo ye-300A isebenzisa iipakethi zebhetri ezintathu, ukwahlula i-300A ngamathathu akuthethi ukuba ipakethi nganye iya kuhlala iphethe i-100A ngqo. Ukwabelana ngoku kunokutshintsha ngokuxhathisa kwepakethi, imeko yokutshaja, ubushushu, ukumelana neentambo, ukumelana noqhagamshelo kunye noyilo lweentambo.

Yenza ubungakanani beBMS kwipakethi nganye ngokwemfuno yombane elindelekileyo yepakethi. Qinisekisa ukuba ibhetri iyaqhubeka itshintsha-tshintsha, i-peak current, ixesha eliphakathi, i-repeat frequency kunye neemeko zobushushu ezijikeleze iBMS.

3. Qinisekisa ukuFaniswa kwePakethi Ngaphambi kokuba uQhagamshele

Iipakethi ezizimeleyo ezenzelwe ukusebenza ngaxeshanye kufuneka zihlolwe ngaphambi kokuba kuqhagamshelwe. Umahluko phakathi kweepakethi unokuchaphazela ukwabelana ngoku kwaye unokudala ukuhamba kombane phakathi kweepakethi xa ziqhagamshelwe.

• Ikhemistri yebhetri
• Ubalo oluchanekileyo lweeseli zochungechunge (ubalo lwe-S)
• I-voltage yephakheji
• Umthamo
• Imeko yentlawulo (i-SOC)
• Imeko yebhetri kunye nobudala apho kufanelekileyo
• Ubushushu bokusebenza

Ukuba iipakethi ziqhagamshelwe kwiivoltheji ezahlukeneyo okanye kwiimeko zokutshaja, umbane ungahamba phakathi kweepakethi xa uqhagamshelwe. Qinisekisa iimeko zonxibelelwano ezivumelekileyo kunye nayo nayiphi na icebo lokuthintela umbane okanye lokukhusela ngaxeshanye ngaphambi kokuba uqhagamshele iipakethi.

4. Qinisekisa ukuba i-Parallel Capacity iyimfuneko eyahlukileyo

I-BMS enekhemistri echanekileyo, inani lothotho kunye novavanyo lwangoku ayifanelekanga ngokuzenzekelayo kwinkqubo ehambelanayo enamaphekhi amaninzi. Ukusebenza okuhambelanayo kufuneka kuqinisekiswe ukuba i-BMS kunye noqwalaselo lweprojekthi luchanekile.

Qinisekisa ukuba uqwalaselo olukhethiweyo lufuna imodyuli eyahlukileyo ehambelanayo okanye esinye isisombululo esihambelanayo, zingaphi iipakethi ezixhaswayo zoqwalaselo ngqo, zeziphi iimeko ze-voltage okanye ze-state-of-charge ezisebenzayo ngaphambi koqhagamshelo, kunye nokuba kukho nawuphi na umsebenzi wokunciphisa okanye wokukhusela ofunekayo.

5. Qinisekisa iimfuno zonxibelelwano ngokwahlukeneyo

Ukuba inkqubo yebhetri ifuna ukutshintshiselana ngedatha ne-inverter, isilawuli, itshaja, isibonisi okanye esinye isixhobo, bonelela ngemodeli yesixhobo ekujoliswe kuso kunye neprotocol yonxibelelwano efunekayo.

Ukuba nojongano lonxibelelwano akuthethi ukuba iiyunithi ezininzi ze-BMS ziya kudibana ngokuzenzekelayo okanye zinxibelelane ngokuchanekileyo nezixhobo ekujoliswe kuzo. Indlela yokuziphatha kwenkqubo kunye neprotocol efunekayo kufuneka iqinisekiswe kwiprojekthi.

6. Yintoni omawuyithumele kwi-DALY yoKhetho lwe-BMS oluhambelana nebhetri

Ukuze uphonononge iprojekthi yebhetri ehambelanayo, nika olu lwazi lulandelayo:

Ngale mibono, iqela lobuchwephesha le-DALY lingaphonononga uqwalaselo olufanelekileyo lwe-BMS, liqinisekise ukuba imodyuli ehambelanayo okanye olunye uqwalaselo oluhambelanayo luyafuneka, liqinisekise iimeko zoqhagamshelo ezifanelekileyo, kwaye libonelele ngolwazi oluhambelanayo lwemveliso kunye nesicatshulwa.

Imibuzo ebuzwa qho

Q1Ngaba kukho naziphi na iipakethi ezimbini zebhetri ye-lithium ezikhuselweyo yi-BMS ezinokudityaniswa ngaxeshanye?

Hayi. Iipakethi zebhetri, ulungelelwaniso lweBMS kunye neemeko zoqhagamshelo ezicwangcisiweyo kufuneka zihlolwe inkqubo ethile ehambelanayo ngaphambi kokuba ziqhagamshelwe.
