Umehluko Phakathi kwama-BJT nama-MOSFET kuma-Battery Management Systems (BMS)

1. Ama-Bipolar Junction Transistors (BJTs):

(1) Isakhiwo:Ama-BJT angamadivayisi e-semiconductor anama-electrode amathathu: isisekelo, i-emitter, kanye nomqoqi. Ngokuyinhloko zisetshenziselwa ukukhulisa noma ukushintsha amasignali. Ama-BJT adinga okokufaka okuncane kusisekelo ukuze alawule ukugeleza kwamanje okukhulu phakathi komqoqi kanye nesithumeli.

(2) Umsebenzi ku-BMS: In I-BMSizinhlelo zokusebenza, ama-BJT asetshenziselwa amakhono awo wamanje wokukhulisa. Zisiza ukuphatha nokulawula ukugeleza kwamanje ngaphakathi kwesistimu, ziqinisekisa ukuthi amabhethri ashajwe futhi akhishwa kahle nangokuphepha.

(3) Izici:Ama-BJT anenzuzo ephezulu yamanje futhi asebenza kahle kakhulu ezinhlelweni ezidinga ukulawulwa kwamanje okunembayo. Ngokuvamile azwela kakhulu ezimeni ezishisayo futhi angahlupheka ngenxa yokuphela kwamandla aphezulu uma kuqhathaniswa nama-MOSFET.

2. I-Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs):

(1) Isakhiwo:Ama-MOSFET angamadivayisi e-semiconductor anamatheminali amathathu: isango, umthombo, kanye nokukhipha amanzi. Basebenzisa i-voltage ukulawula ukuhamba kwamandla phakathi komthombo nokukhipha amanzi, okubenza basebenze kahle kakhulu ekushintsheni izinhlelo zokusebenza.

(2) Umsebenzi kuI-BMS:Ezinhlelweni ze-BMS, ama-MOSFET avame ukusetshenziselwa amandla awo okushintsha asebenzayo. Angakwazi ukuvula nokuvala ngokushesha, alawule ukugeleza kwamanje ngokumelana okuncane nokulahlekelwa amandla. Lokhu kuwenza alungele ukuvikela amabhethri ekushajweni ngokweqile, ukuchitheka ngokweqile, namasekhethi amafushane.

(3) Izici:Ama-MOSFET ane-impedance ephezulu yokufaka kanye nokumelana okuphansi, okuwenza asebenze kahle kakhulu ngokukhipha ukushisa okuphansi uma kuqhathaniswa nama-BJT. Zifanele ikakhulukazi izinhlelo zokusebenza zokushintsha ezinesivinini esikhulu nezisebenza kahle kakhulu ngaphakathi kwe-BMS.

Isifinyezo:

• BJTszingcono kuzinhlelo zokusebenza ezidinga ukulawula kwamanje okunembile ngenxa yenzuzo yazo yamanje ephezulu.
• Ama-MOSFETzikhethwa ekushintsheni okuphumelelayo nokushesha ngokukhipha ukushisa okuphansi, okuzenza zilungele ukuvikela nokuphatha ukusebenza kwebhethriI-BMS.
