Kusiyana Pakati peBJTs neMOSFETs muBattery Management Systems (BMS)

1. Matransistors eBipolar Junction (BJTs):

(1) Maumbirwo:MaBJT zvishandiso zve semiconductor zvine maerekitirodhi matatu: base, emitter, uye collector. Anonyanya kushandiswa pakuwedzera kana kushandura masaini. MaBJT anoda simba diki rinopinda kubase kuti ridzore kuyerera kukuru kwesimba pakati pemuunganidzi ne emitter.

(2) Basa muBMS: In BMSMashandisirwo, maBJT anoshandiswa nekuda kwekugona kwawo kuwedzera simba. Anobatsira kudzora kufamba kwemagetsi mukati mesystem, zvichiita kuti mabhatiri achajiswe uye aburitswe zvakanaka uye zvakachengeteka.

(3) Hunhu:MaBJT ane simba guru remagetsi uye anoshanda zvikuru mukushandiswa kunoda kudzorwa kwakarurama kwemagetsi. Anowanzo nzwa zvakanyanya mamiriro ekupisa uye anogona kukanganiswa nekupararira kwesimba rakawanda zvichienzaniswa neMOSFET.

2. Matransistor eMunda-Mhedzisiro yeSimbi-Oxide-Semiconductor (MOSFET):

(1) Maumbirwo:MOSFET zvishandiso zve semiconductor zvine materminal matatu: gedhi, tsime, uye drain. Zvinoshandisa voltage kudzora kufamba kwemagetsi pakati petsime nedrain, zvichiita kuti zvive zvinobudirira zvikuru pakushandura mashandisirwo.

(2) Basa muBMS:Mumashandisirwo eBMS, maMOSFET anowanzo shandiswa nekuda kwekugona kwawo kushandura zvakanaka. Anogona kuvhura nekudzima nekukurumidza, achidzora kufamba kwemagetsi pasina simba rakawanda uye kurasikirwa nesimba. Izvi zvinoita kuti ave akakodzera kudzivirira mabhatiri kubva pakuchaja zvakanyanya, kuburitsa magetsi zvakanyanya, uye mashort circuits.

(3) Hunhu:MaMOSFET ane simba guru rekupinza magetsi uye haapindi simba zvakanyanya, zvichiita kuti ashande zvakanaka uye haapise kupisa zvakanyanya kana tichienzanisa nemaBJT. Anonyanya kukodzera kushandiswa kwekuchinja nekukurumidza uye kushanda zvakanaka mukati meBMS.

Pfupiso:

• MaBJTzviri nani kune mapurogiramu anoda kudzorwa kwakarurama kwemagetsi nekuda kwekuwedzera kwawo simba remagetsi.
• MOSFETZvinonyanya kufarirwa pakushandura nekukurumidza uye zvinobudirira uye zvinoderedza kupisa, zvichiita kuti zvive zvakanaka pakudzivirira nekutarisira mashandiro ebhatiri muBMS.
