Beschreibung
Zusammenfassung:	The invention relates to an automatic thermal management device of an electric vehicle battery. According to the invention, the device consists of one or several mobile grids (1) placed on the lateral side of a battery casing (2) provided with ventilation slots (3) which can be closed and opened by means of bimetallic levers (4) which, when the temperature inside the vehicle battery increases or drops and the air having the respective temperature passes through a slot (8) provided in the casing, act upon a guide (5) of some rotating cylinders (6) to displace and position the mobile grid (1) within some guiding profiles (7) provided both at the top and at the bottom of the battery casing (2), thereby achieving ventilation with ambient air and maintaining the temperature inside the battery within the preset limits. Invenţia se referă la un dispozitiv automat de management termic al unei baterii ce echipează un vehicul electric. Dispozitivul, conform invenţiei, este alcătuit din una sau mai multe grile mobile (1) amplasate pe partea laterală a unei carcase de baterie (2) prevăzute cu fante de ventilare (3) a căror închidere şi deschidere se realizează prin intermediul unor pârghii bimetalice (4), care, atunci când temperatura din interiorul bateriei de vehicul creşte sau scade, iar aerul cu temperatura respectivă circulă printr-o fantă (8) prevăzută în carcasă, acţionează asupra unui ghidaj (5) al unor cilindri rotitori (6), care determină deplasarea şi poziţionarea grilei mobile (1) în cadrul unor profile de ghidaj (7), prevăzute atât la partea superioară, cât şi la partea inferioară a carcasei de baterie (2), realizându-se astfel ventilarea cu aer ambiental şi menţinerea temperaturii în limitele prestabilite în interiorul bateriei.
