Musiyano Pakati peBJTs neMOSFETs muBattery Management Systems (BMS)

1. Bipolar Junction Transistors (BJTs):

(1) Chimiro:BJTs semiconductor zvishandiso zvine matatu maelectrode: base, emitter, uye muunganidzi. Iwo anonyanya kushandiswa kukwidziridza kana kushandura masaini. BJTs inoda diki yekupinza ikozvino kune hwaro kudzora yakakura ikozvino kuyerera pakati pemuunganidzi uye emitter.

(2) Basa muBMS: In BMSmaapplication, BJTs anoshandiswa kune azvino kusimudzira kugona. Ivo vanobatsira kubata nekugadzirisa kuyerera kwazvino mukati meiyo sisitimu, kuve nechokwadi chekuti mabhatiri akachajwa uye anoburitswa zvakanaka uye zvakachengeteka.

(3) Hunhu:BJTs vane hupfumi hwepamusoro uye hunoshanda zvakanyanya mumashandisirwo anoda chaiwo kutonga ikozvino. Ivo vanowanzo nyanya kutarisisa mamiriro ekupisa uye vanogona kutambura kubva kune yakakwira simba dissipation kana ichienzaniswa neMOSFETs.

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

(1) Chimiro:MOSFETs semiconductor zvishandiso zvine matatu materminal: gedhi, sosi, uye dhizaini. Ivo vanoshandisa voltage kudzora kuyerera kweazvino pakati pechitubu nekudonhedza, zvichiita kuti vanyatso shanda mukuchinja maapplication.

(2) Basa mukatiBMS:Mumashandisirwo eBMS, maMOSFET anowanzo shandiswa pakugona kwavo kushandura. Vanogona kukurumidza kuvhara uye kuvhara, kutonga kuyerera kwezvino nekupikisa kushoma uye kurasikirwa kwesimba. Izvi zvinovaita kuti vave vakanaka pakudzivirira mabhatiri kubva pakuwandisa, kubuda zvakanyanya, uye mapfupi maseketi.

(3) Hunhu:MOSFETs ine yakakwira yekupinza impedance uye yakaderera pa-resistance, ichiita kuti ishande zvakanyanya nekudzikira kupisa kwekudzikira zvichienzaniswa neBJTs. Ivo vanonyanya kukodzera kune yakakwirira-kumhanya uye yakakwirira-inoshanda switching application mukati meBMS.

Pfupiso:

• BJTszviri nani kune zvikumbiro zvinoda kudzorwa kwazvino nekuda kwekuwana kwavo kwazvino.
• MOSFETsinosarudzwa kushanda uye nekukurumidza kuchinjika nekudzikira kupisa kupisa, zvichiita kuti ive yakanakira kuchengetedza nekugadzirisa mashandiro ebhatiri mu.BMS.
