Isistimu yokutholwa kwezinga lokushisa ye-BMS nendlela yokulinganisa esekelwe kunzwa yezinga lokushisa ye-NTC

Ubuchwepheshe belungelo lobunikazi buhlobene nenkundla yokutholwa kwezinga lokushisa kwebhethri lezimoto zikagesi, ikakhulukazi kusistimu yokutholwa kwezinga lokushisa le-BMS esekelwe kunzwa yezinga lokushisa ye-NTC kanye nendlela yokulinganisa.

Njengamanje, izinzwa zokushisa zisetshenziswa kabanzi emkhakheni wamandla amasha, ikakhulukazi uhlelo lokuphatha amabhethri ezimoto zamandla amasha, okuyi-BMS. Njengamanje, i-resistance temperature detector (RTD) kanye ne-thermocouple kuhlanganiswe namasekhethi okulinganisa ahambisanayo kuvame ukusetshenziselwa ukuqoqa izinga lokushisa. Amasekhethi amasampula okushisa ahlanganisa indlela yokuhlukanisa i-voltage yokumelana kanye nendlela yamanje yokuvuselela umthombo wamanje. Kodwa-ke, lezi zindlela ezingenhla zinamaphutha alandelayo: 1. Ukuthola isignali ye-analog ye-RTD kanye nesifunda sokucubungula kuyinkimbinkimbi futhi izindleko ziphezulu. Amandla adingekayo ukuze inzwa inikwe amandla azoletha ukukhuphuka kwezinga lokushisa kwangaphakathi futhi andise iphutha lokulinganisa izinga lokushisa. Ngesikhathi esifanayo, izindleko zalolu hlelo ziphakeme, futhi umthamo wesifunda weyunithi yokutholwa mkhulu, ongahambisani ne-miniaturization. 2. Ngenxa yokuzwela okuphansi kwe-thermocouple, kuyadingeka ukukhulisa isignali eqoqwe nge-low offset amplifier. Ukwengeza, ukuhambisana kwezinga lokushisa kwe-thermocouple akulungile, ngakho-ke kuyadingeka ukunxephezela isifunda, okwandisa iphutha lesampula futhi kunciphisa ukunemba kwesampula. 3. Njengamanje, indlela ye-thermistor ehlanganiswe nokuhlukaniswa kwe-voltage yokumelana ivame kakhulu. Isizathu esiyinhloko sokwamukela lolu hlelo ukuthi izitayela ze-thermistor zihlukahlukene futhi intengo iphansi. Nokho, ukunemba kokutholwa kwe-thermistor kuphansi; Ukufingqa, kunzima ukudinga isikimu sokutholwa kwezinga lokushisa elinembayo eliphezulu kanye nenani eliphansi. Lihlose ukushiyeka kohlelo olukhona lokutholwa kwezinga lokushisa, leli phepha libeka phambili indlela yokutholwa kwezinga lokushisa enembayo ephezulu neshibhile, elungele izinhlelo ezintsha zokuphatha ibhethri lamandla nezinye izinkambu.
