6.Uyilo lwesoftware ye-BMS
lUlawulo lwe-voltage ephezulu nephantsi
Xa ivuliwe ngokuqhelekileyo, i-BMS ivuswa yi-VCU ngomgca oqinileyo okanye isignali ye-CAN ye-12V. Emva kokuba i-BMS izigqibile ukuzihlola kwaye ingena kwi-standby, i-VCU ithumela umyalelo we-high-voltage, kwaye i-BMS ilawula ukuvalwa kwe-relay ukuze igqibezele uqhagamshelo lwe-high-voltage. Xa ivuliwe, i-VCU ithumela umyalelo we-low-voltage ize ikhuphe i-12V wake-up. Xa umpu ufakwe ukuze utshaje kwimeko yokucima umbane, ungavuswa sisignali ye-CP okanye ye-A+.
lUlawulo lokutshaja
(1) Ukutshaja kancinci
Ukutshaja kancinci kukutshaja ibhetri ngombane othe ngqo oguqulwe ukusuka kumbane otshintshanayo yitshaja esebhodini yenqwaba yokutshaja (okanye umbane we-220V). Iinkcukacha zenqwaba yokutshaja ngokubanzi ziyi-16A, 32A, kunye ne-64A, kwaye inokutshaja ngombane wasekhaya. I-BMS inokuvuswa sisignali ye-CC okanye ye-CP, kodwa kufuneka kuqinisekiswe ukuba ingalala ngokuqhelekileyo emva kokuba itshajiwe. Inkqubo yokutshaja ye-AC ilula kwaye inokuphuhliswa ngokuhambelana nemigangatho yesizwe eneenkcukacha.
(2) Ukutshaja ngokukhawuleza
Ukutshaja ngokukhawuleza kukutshaja ibhetri ngombane ophuma ngqo kwinqwaba yokutshaja yeDC, enokufikelela kwi-1C okanye izinga eliphezulu lokutshaja. Ngokubanzi, i-80% yebhetri inokutshaja kwimizuzu engama-45. Ingavuswa ngumthombo wamandla oncedisayo we-A+ wenqwaba yokutshaja.
lUmsebenzi woqikelelo
(1) I-SOP (State of Power) ifumana amandla okutshaja nokukhupha ibhetri ngokujonga iitafile ngokusebenzisa ubushushu kunye ne-SOC. I-VCU imisela indlela esetyenziswa ngayo yonke imoto ngokusekelwe kwixabiso lamandla elithunyelweyo.
(2) I-SOH (Imeko yezeMpilo) ikakhulu ichaza imeko yempilo yebhetri yangoku, enexabiso eliphakathi kwe-0-100%. Ngokuqhelekileyo kucingelwa ukuba ibhetri ayinakusetyenziswa emva kokuba iwele ngaphantsi kwe-80%.
(3) I-SOC (Imeko yokuTshaja) ikwi-algorithm yokulawula engundoqo ye-BMS, echaza imeko yangoku yamandla aseleyo. Isekelwe kakhulu kwindlela yokudibanisa i-ampere-hour kunye ne-algorithm ye-EKF (extended Kalman filter), edityaniswe namaqhinga okulungisa (njengokulungiswa kwevolthi evulekileyo, ukulungiswa kwetshaja epheleleyo, ukulungiswa kokuphela kwetshaja, ukulungiswa komthamo phantsi kwamaqondo obushushu ahlukeneyo kunye ne-SOH, njl.njl.).
(4) I-algorithm ye-SOE (State of Energy) ayiphuhliswanga kakhulu ngabavelisi basekhaya okanye isebenzisa ii-algorithms ezilula ukufumana umlinganiselo wamandla aseleyo phantsi kwemeko yangoku kumandla aphezulu afumanekayo. Lo msebenzi usetyenziselwa kakhulu ukuqikelela uluhlu lokuhamba ngenqanawa oluseleyo.
lUkuxilongwa kwempazamo
Amanqanaba ahlukeneyo empazamo ayahlulwa ngokwendlela ibhetri esebenza ngayo, kwaye amanyathelo ahlukeneyo okucubungula athathwa yi-BMS kunye ne-VCU phantsi kwamanqanaba ahlukeneyo empazamo, njengezilumkiso, umda wamandla, okanye ukunqanyulwa ngokuthe ngqo kwevolthi ephezulu. Iimpazamo ziquka ukufunyanwa kwedatha kunye neempazamo zengqiqo, iimpazamo zombane (ii-sensors kunye nee-actuators), iimpazamo zonxibelelwano, kunye neempazamo zesimo sebhetri, njl.
