Isishwankathelo seSikhokelo

Ukuba wakha ibhetri yesithuthuthu sombane kwimarike yaseIndiya, ukhetho lwe-BMS kufuneka luqale ngeemfuno zenkqubo yebhetri kunye nolawulo endaweni yelebheli yamandla emoto kuphela. Qinisekisa ikhemistri yebhetri kunye nenani elichanekileyo leeseli zochungechunge, ibhetri eqhubekayo ecaleni kwayo kunye nombane ophezulu, iimeko zokusebenza, kunye naluphi na unxibelelwano olufunekayo nomlawuli okanye ideshibhodi.

Kwiiprojekthi ezikwimida ye-AIS-156, imisebenzi yokhuseleko ye-BMS kunye neemfuno ezipheleleyo zokuvunywa kweNkqubo yokuGcina amandla oMbane eTshajwayo (REESS) nazo kufuneka ziqwalaselwe. Ukukhetha i-BMS yodwa akwenzi inkqubo epheleleyo yebhetri ihambelane ne-AIS-156.

1. Qala ngeBattery Chemistry kunye ne-Exact S Count

Ngaphambi kokuba uthelekise ukulinganiswa kwangoku kwe-BMS, qinisekisa ikhemistri yebhetri, inani elichanekileyo leeseli eziqhagamshelwe kuthotho (ubalo lwe-S), i-voltage yephakheji eqhelekileyo kunye nemida yokutshaja. I-LiFePO4, i-NCM/Li-ion kunye nezinye iikhemistri ze-lithium zisebenzisa uluhlu olwahlukileyo lwe-cell-voltage, ngoko ke i-BMS kufuneka ihambelane noyilo lwebhetri yokwenyani.

Musa ukuqikelela inani elichanekileyo le-S kwileyibhile ye-pack-voltage eqhelekileyo yodwa. Sebenzisa uyilo lwe-battery-pack okanye iinkcukacha zeseli njengesalathiso sokugqibela.

2. Yenza ubungakanani beBMS bube yiBhetri-Side Current, hayi iMotor Power yodwa

Amandla emoto lulwazi oluluncedo oluvela kwimvelaphi, kodwa aluchazi ngokukodwa umlinganiselo wangoku we-BMS. I-BMS ibona umbane osecaleni kwebhetri, ochaphazeleka nayi-pack voltage, umda wamandla ombane webhetri yomlawuli, imfuno yokukhawulezisa, ubunzima besithuthi, ii-gradients, iimeko zokuqhuba kunye nobushushu bokusebenza.

Ngaphambi kokuba ukhethe inqanaba langoku le-BMS, qinisekisa:

• Ibhetri yangoku eqhubekayo elindelekileyo
• Ulawulo oluphezulu lwangoku lwebhetri
• Ubuninzi bebhetri yangoku ephezulu
• Ubude bexesha eliphambili kunye nokuphindaphinda rhoqo
• Umbane wokutshaja ovuselelayo ophezulu, ukuba kusetyenziswa ibhuleki yokuvuselela

3. Jonga uMbane oQhubekekayo kunye noweNqanaba ngokwahlukeneyo

Umsinga oqhubekayo kunye nomsinga omfutshane wexesha elide ziimfuno ezahlukeneyo. I-BMS ehlangabezana nomsinga oqhelekileyo wokukhwela isadinga ukujongwa malunga nokukhawulezisa, ukunyuka kunye nezinye iincopho zexesha elifutshane.

Xa ucela isindululo, nika zombini umbane ophezulu kunye nokuba uhlala ixesha elingakanani. Musa ukuyivuma i-BMS kuphela kuba umlinganiselo wayo wombane oqhubekayo ubonakala usondele kumthwalo olindelekileyo.

4. Qinisekisa uNxibelelwano loMlawuli kunye neDashboard

Ukuba i-BMS ifuna ukunxibelelana nomlawuli wesithuthuthu, ideshibhodi okanye enye iyunithi yolawulo lwe-elektroniki, nika imodeli yesixhobo kunye neprotocol yonxibelelwano efunekayo.

I-Controller Area Network (CAN), i-RS485 kunye ne-UART zichaza ii-interfaces zonxibelelwano. Ukuba ne-interface efanayo akuthethi ngokuzenzekelayo ukuba izixhobo ezimbini zinokutshintshiselana imiyalezo efunekayo. I-protocol kunye ne-data mapping nazo kufuneka zihambelane nezixhobo ekujoliswe kuzo.

5. Ithetha ukuthini i-AIS-156 kuKhetho lwe-BMS

I-AIS-156 imisela iimfuno zokhuseleko kwiiNkqubo zokugcina amandla ombane ezitshajwayo (i-REESS) ezisetyenziswa kwizithuthi zombane zodidi lwe-L, kuquka neemoto zombane ezinamavili amabini. I-BMS yinxalenye ye-REESS epheleleyo evavanyiweyo kwinkqubo yokuvunywa kwesithuthi.

Isihlomelo se-AIS-156 3 sichaza i-BMS esekelwe kwi-microprocessor okanye kwi-microcontroller kwaye sichonga imisebenzi yokhuseleko eqinisekiswayo ngexesha lovavanyo lwe-REESS, kubandakanya i-over-voltage, i-over-charge, i-over-discharge, i-over-temperature, i-overcurrent kunye ne-short-circuit protection. Iimfuneko zokuhambelana kwe-electromagnetic (EMC) ezisetyenziswayo nazo kufuneka ziqwalaselwe.
