Iindaba - Izinto Eziphambili Ezichaphazela Ubomi Bebhetri Ye-EV: Indima Ye-BMS

Njengoko izithuthi zombane (ii-EV) zisanda kuthandwa kwihlabathi liphela, ukuqonda izinto ezichaphazela ubomi bebhetri ye-lithium-ion kuye kwaba yinto ebalulekileyo kubathengi nakwiingcali zoshishino ngokufanayo. Ngaphaya kwemikhwa yokutshaja kunye neemeko zokusingqongileyo, iNkqubo yoLawulo lweBhetri (i-BMS) ekumgangatho ophezulu ivela njengenxalenye ebalulekileyo ekwandiseni ukuqina nokusebenza kwebhetri.

Ukuziphatha kokutshaja kugqama njengeyona nto iphambili. Ukutshaja rhoqo (0-100%) kunye nokutshaja ngokukhawuleza kunokukhawulezisa ukonakala kwebhetri, ngelixa ukugcina inqanaba lokutshaja phakathi kwama-20-80% kunciphisa uxinzelelo kwiiseli. I-BMS enobuchule iyanciphisa oku ngokulawula umbane wokutshaja kunye nokuthintela ukutshaja okugqithisileyo—ukuqinisekisa ukuba iiseli zifumana umbane ohambelanayo kwaye ziphephe ukuguga ngaphambi kwexesha.

Ubushushu obugqithisileyo bukwabeka nemingcipheko emikhulu. Iibhetri zeLithium-ion ziyachuma phakathi kwe-15-35°C; ukuvezwa kumaqondo obushushu angaphezu kwe-45°C okanye ngaphantsi kwe--10°C kuyaphazamisa uzinzo lweekhemikhali. Izisombululo zeBMS eziphambili ziquka iimpawu zolawulo lobushushu, ukujonga amaqondo obushushu ebhetri ngexesha langempela kunye nokulungisa ukusebenza ukuze kuthintelwe ukugqithisa okanye umonakalo onxulumene nokubanda. Oku kubaluleke kakhulu kwii-EV ezisebenza kwiindawo ezishushu, apho ukuguquguquka kwamaqondo obushushu kuxhaphakileyo.

Ukungalingani kweeseli lolunye usongo olufihlakeleyo. Kwaneebhetri ezintsha zinokuba notshintsho oluncinci kumthamo weeseli, kwaye ngokuhamba kwexesha, olu mahluko luyanda—lunciphisa ukusebenza kakuhle kwebhetri iyonke kunye nobomi bayo. I-Active Balancing BMS ijongana noku ngokusasaza amandla phakathi kweeseli, igcina amanqanaba ombane afanayo. Lo msebenzi ubaluleke kakhulu kwiipakethi zeebhetri ze-EV, ezixhomekeke kumakhulu eeseli ezisebenza kakuhle.

Ezinye izinto ezinegalelo ziquka iimeko zokugcina (ukuphepha ukutshaja ixesha elide okanye ukungabi nanto) kunye nobungakanani bokusetyenziswa (ukukhawulezisa rhoqo ngesantya esiphezulu kunciphisa iibhetri ngokukhawuleza). Nangona kunjalo, xa zidityaniswe neNkqubo yoLawulo lweBhetri ethembekileyo, ezi mpembelelo zinokuncitshiswa. Njengoko itekhnoloji ye-EV itshintsha, i-BMS iyaqhubeka nokudlala indima ephambili ekuphuculeni ubomi bebhetri, nto leyo eyenza ukuba ibe yinto ephambili kuye nabani na otyala imali ekuhambeleni phambili kombane.
