Isicelo se-Battery Simulator ekuhlolweni kwe-BMS

Njengengxenye ye-elekthronikhi yokuqapha isikhathi sangempela, ukulinganisa okusebenzayo, nokushaja nokukhishwa okukhaliphile, uhlelo lokuphathwa kwebhethri (i-BMS) lidlala indima ebalulekile ekuqinisekiseni ukuphepha kwebhethri, ukwelula impilo, ukulinganisa amandla asele, futhi yingxenye ebalulekile yamandla namandla amaphakethe webhethri yokugcina.

Ake sithathe ibhethri ye-lithium njengesibonelo. Ibhethri kufanele lisebenzisane nohlelo lokulawulwa kokushaja nokukhipha (BMS) ukuze kuqinisekiswe ukusebenza okujwayelekile nezici. Kunzima ukulingisa izici zebhethri nokuhlola ukusebenza kwe-BMS. Kodwa-ke, uma imisebenzi yokukhipha amandla nokumuncwa ihlanganiswe nethuluzi elizimele, inkimbinkimbi yokusebenzisa ukunikezwa kwamandla kwe-DC ehlukene nomthwalo we-elekthronikhi ukuze kulungiswe ukuphuma kwamandla nokumuncwa kungancipha kakhulu. Ngemva kokuhlanganisa le misebenzi, ingasebenza ngaphansi kokulawulwa kwe-loop evaliwe ukuze inikeze ukushintshwa okuphelele, okungeyona eyesikhashana phakathi kokukhiphayo nokumuncwa, futhi ibone ukushintsha kwamandla nomthwalo okungenazihibe. Ukuze kuhlangatshezwane nezidingo zamanje ze-dual-quadrant kanye ne-industrial test application, i-NGI ithuthukise isifanisi sebhethri esinembe kakhulu seziteshi eziyisishiyagalombili se-N8358.

I-N8358 iyi-simulator yebhethri ehlelwe ngamandla aphansi, ukunemba okuphezulu kanye neziteshi eziningi. Ngokwamukela ukwakheka kwe-double-quadrant, okwamanje kungakhokhiswa futhi kukhishwe, okunganelisa izidingo zokuhlolwa kwe-BMS.

I-N8358 ezimele inganikeza ukulingiswa kwamaseli webhethri yesiteshi esingu-8, ngempendulo yokuxhumana esheshayo nokulingiswa kwephutha okwakhelwe ngaphakathi. Ukugeleza kwamanje kwe-Bidirectional kungasetshenziswa ukuhlola ukulinganisa okusebenzayo kwe-BMS. Ukutholwa kwamanje okunemba okuphezulu kwenza i-N8358 ivivinye ukusetshenziswa kwamandla we-static wesekethe yokutholwa kwe-BMS. Zonke lezi zici zenza i-N8358 ibe ukukhetha okufanele ukuhlolwa kwe-BMS.

Test izinto
Ukuhlolwa kokunemba kokutholakala kwamandla kagesi webhethri
Ukuhlolwa kwepharamitha yokuvikela ibhethri
Ukuhlolwa kokulinganisa ibhethri
Ukuhlolwa kokusetshenziswa kwamandla okuqinile kwesekethe yokutholwa kwe-BMS

Ukulingiswa kwephutha lebhethri
Ngokwakhiwa kwamabhidi womabili, izinkomba zamanje zokufaka nezokukhishwa kwesiteshi ngasinye zingalawulwa ngokulandelana. Abasebenzisi bangenza ngokwezifiso ukushaja kwebhethri nemodeli yokukhipha, ehlangabezana ngokugcwele nezidingo zokuhlolwa kokulinganisa okusebenzayo kwe-BMS.

I-N8358 inokunemba okuphezulu kwamanje, kufika ku-1μA. Ukunemba kwesilinganiso esiphezulu se-N8358 kungahlulela ngokunembile amandla kagesi kanye nokunemba kwamanje kokutholwa kwe-BMS elinganisiwe. I-voltage eqoqwe yi-N8358 ingafaniswa ne-voltage yeseli yebhethri etholwe yi-BMS ukuze kutholwe ukunemba kokutholwa kwe-voltage ye-BMS. I-NGI ingahlinzeka ngohlelo oluphelele lokuhlola lwe-BMS olunesifanisi sebhethri, umthwalo we-electronic we-DC, ikhadi lokulingisa izinga lokushisa kanye nokuphakelwa kwamandla kagesi we-DC anamandla amakhulu.
