Gestionarea termic\u0103 a bateriilor este esen\u021bial\u0103 pentru vehiculele comerciale electrice. F\u0103r\u0103 un control adecvat al temperaturii, bateriile prezint\u0103 performan\u021be reduse, degradare accelerat\u0103 \u0219i riscuri poten\u021biale pentru siguran\u021b\u0103. Sistemele de gestionare termic\u0103 a bateriilor r\u0103cite cu ap\u0103 (BTMS) au ap\u0103rut ca standard industrial pentru gestionarea temperaturilor bateriilor \u00een aplica\u021biile solicitante ale vehiculelor comerciale.<\/p>\n\n\n\n
Cum func\u021bioneaz\u0103 BTMS r\u0103cit cu ap\u0103<\/strong><\/p>\n\n\n\n Un BTMS r\u0103cit cu ap\u0103 utilizeaz\u0103 lichidul de r\u0103cire ca agent de transfer termic, circul\u00e2nd prin acumulator pentru a absorbi \u0219i elimina c\u0103ldura \u00een exces. Sistemul const\u0103 din cinci componente principale: un compresor, un evaporator, un condensator, o supap\u0103 de expansiune \u0219i un schimb\u0103tor de c\u0103ldur\u0103 cu pl\u0103ci. Prin ajustarea temperaturii \u0219i a debitului lichidului de r\u0103cire, sistemul men\u021bine acumulatorul \u00een intervalul optim de temperatur\u0103 de func\u021bionare - de obicei \u00eentre 15\u00b0C \u0219i 35\u00b0C pentru bateriile litiu-ion.<\/p>\n\n\n\n Principiul de func\u021bionare urmeaz\u0103 un ciclu de refrigerare \u00een bucl\u0103 \u00eenchis\u0103. Lichidul de r\u0103cire fierbinte din acumulator curge c\u0103tre unitatea de r\u0103cire, unde c\u0103ldura este transferat\u0103 c\u0103tre lichidul de r\u0103cire. Agentul de r\u0103cire r\u0103cit circul\u0103 apoi \u00eenapoi prin acumulator, absorbind mai mult\u0103 c\u0103ldur\u0103 \u00eentr-un ciclu continuu. \u00cen condi\u021bii de vreme rece, un \u00eenc\u0103lzitor de lichid PTC (coeficient pozitiv de temperatur\u0103) op\u021bional poate \u00eenc\u0103lzi agentul de r\u0103cire pentru a se asigura c\u0103 bateriile r\u0103m\u00e2n \u00een limitele de temperatur\u0103 acceptabile.<\/p>\n\n\n\n De ce vehiculele comerciale au nevoie de BTMS avansate<\/strong><\/p>\n\n\n\n Vehiculele comerciale func\u021bioneaz\u0103 \u00een condi\u021bii mai solicitante dec\u00e2t autoturismele.

Capacitatea bateriei poate sc\u0103dea cu p\u00e2n\u0103 la 50% \u00een condi\u021bii de frig extrem, \u00een timp ce c\u0103ldura excesiv\u0103 accelereaz\u0103 degradarea bateriei, put\u00e2nd reduce durata de via\u021b\u0103 a bateriei cu 30% sau mai mult. Pentru operatorii de flote comerciale, ace\u0219ti factori au un impact direct asupra eficien\u021bei opera\u021bionale \u0219i a costului total de proprietate.<\/p>\n\n\n\n Componente \u0219i specifica\u021bii cheie<\/strong><\/p>\n\n\n\n Unit\u0103\u021bile BTMS moderne r\u0103cite cu ap\u0103 pentru vehicule comerciale includ mai multe caracteristici esen\u021biale:<\/p>\n\n\n\n Unitatea de r\u0103cire are de obicei o capacitate de r\u0103cire cuprins\u0103 \u00eentre 5 kW \u0219i 16 kW, selectat\u0103 \u00een func\u021bie de tipul vehiculului \u0219i de m\u0103rimea bateriei.
