Izindaba - Izici Eziyinhloko Ezithinta Isikhathi Sokuphila Kwebhethri Le-EV: Indima Ye-BMS

Njengoba izimoto zikagesi (ama-EV) zithola ukuthandwa emhlabeni wonke, ukuqonda izici ezithinta isikhathi sokuphila kwebhethri le-lithium-ion sekubalulekile kubathengi kanye nochwepheshe bemboni ngokufanayo. Ngaphandle kwemikhuba yokushaja kanye nezimo zemvelo, i-Battery Management System (BMS) esezingeni eliphezulu ivela njengengxenye ebalulekile ekwandiseni ukuqina nokusebenza kwebhethri.

Ukuziphatha kokushaja kuvelele njengesici esiyinhloko. Ukushaja okugcwele njalo (0-100%) kanye nokushaja okusheshayo kungasheshisa ukuwohloka kwebhethri, kuyilapho ukugcina izinga lokushaja liphakathi kuka-20-80% kunciphisa ukucindezeleka kumaseli. I-BMS eyinkimbinkimbi inciphisa lokhu ngokulawula amandla okushaja nokuvimbela ukushaja ngokweqile—ukuqinisekisa ukuthi amaseli athola i-voltage engaguquki futhi agweme ukuguga ngaphambi kwesikhathi.

Ukweqisa kwezinga lokushisa nakho kubeka izingozi ezinkulu. Amabhethri e-lithium-ion achuma phakathi kuka-15-35°C; ukuchayeka emazingeni okushisa angaphezu kuka-45°C noma ngaphansi kuka--10°C kuphazamisa ukuzinza kwamakhemikhali. Izixazululo ze-BMS ezithuthukisiwe zifaka izici zokuphatha ukushisa, ukuqapha izinga lokushisa lebhethri ngesikhathi sangempela kanye nokulungisa ukusebenza ukuze kuvinjelwe ukushisa ngokweqile noma umonakalo ohlobene nokubanda. Lokhu kubaluleke kakhulu kuma-EV asebenza ezindaweni ezishisayo, lapho kuvamile khona ukushintshashintsha kwezinga lokushisa.

Ukungalingani kwamaseli kungenye ingozi efihliwe. Ngisho namabhethri amasha angase abe nokwehluka okuncane kumthamo wamaseli, futhi ngokuhamba kwesikhathi, lokhu kwehluka kuyakhula—kunciphisa ukusebenza kahle kwebhethri kanye nesikhathi sokuphila. I-Active Balancing BMS ibhekana nalokhu ngokusabalalisa kabusha amandla phakathi kwamaseli, igcina amazinga e-voltage afanayo. Lo msebenzi ubaluleke kakhulu kuma-EV battery packs, athembele kumakhulu amaseli asebenza ngokuvumelana.

Ezinye izici ezibangela lokhu zifaka phakathi izimo zokugcina (ukugwema ukushaja okugcwele noma okungenalutho isikhathi eside) kanye nokusetshenziswa okunamandla (ukusheshisa okusheshayo okuvamile kunciphisa amabhethri ngokushesha). Uma kuhlanganiswe nohlelo lokuphatha ibhethri oluthembekile, nokho, le miphumela ingancishiswa. Njengoba ubuchwepheshe be-EV buthuthuka, i-BMS iyaqhubeka nokudlala indima ebalulekile ekwenzeni ngcono isikhathi sokuphila kwebhethri, okwenza kube yinto ebalulekile kunoma ubani otshala imali ekuhambeni kukagesi.
