Kuzivisa kukosha kweLithium Battery Protection Board

Mabhatiri eLithium anozivikanwa nekuwanda kwesimba rawo, zvichiita kuti ave akakodzera kugonesa huwandu hwakawanda hwemidziyo yemagetsi. Nekudaro, chemistry yavo haina kugadzikana, ichiita kuti vagone kukuvara kubva pakuchaja, kuburitsa zvakanyanya, uye nekukurumidza kuburitsa. Kudzikamisa njodzi idzi uye kuve nechokwadi chekushanda kwakakwana uye kuchengetedzeka, lithium mabhatiri anoda yakasimba kuchengetedza system. Iri gwaro rinotsvaga kuomesesa kwelithium bhatiri kuchengetedza mabhodhi uye bhatiri manejimendi masisitimu (BMS), kuratidza dhizaini yavo, kushanda, uye kukosha mumagetsi emazuva ano.

Bhodhi rekudzivirira bhatiri re lithium rine hardware ine chekuita nekuchengetedzeka, saka nzira dzeMOSFET, kukwira kwekupisa, uye dziviriro yekukanganisa zvinofanirwa kuongororwa nekuchengetedzwa kwePCB pamusoro pemvura uye kusimbiswa kuburikidza nekuyedzwa kwemagetsi.

Kunzwisisa Lithium Battery Dziviriro Mabhodhi

Lithium bhatiri ekudzivirira mabhodhi anoita basa rakakosha mukuona kushanda kwakachengeteka uye kwakavimbika kwemabhatiri e lithium. Aya mabhodhi anoshanda sechivharo chinodzivirira panjodzi dzakasiyana siyana dzinogona kukanganisa kushanda kwebhatiri, kurarama kwenguva refu, uye kuchengeteka. Pakati pezvinotyisidzira zvakanyanya izvo mabhodhi ekudzivirira anodzivirira kudhurisa, kuburitsa-kudarika, uye kuburitsa zvakanyanya, imwe neimwe inogona kukonzeresa kukuvadzwa kukuru kana kutadza kutadza kwebhatiri.

Mabhodhi ekudzivirira magungano akaomesesa anosanganisira akasiyana emagetsi zvikamu, chimwe nechimwe chinobatsira mukushanda kwese uye kushanda kwehurongwa. Zvinhu zvakakosha zvinowanzowanikwa mumabhodhi ekudzivirira zvinosanganisira maseketi akabatanidzwa (ICs), metal-oxide semiconductor (MOS) switch, capacitors, resistors, negative tembiricha coefficient thermistors (NTCs), yakanaka tembiricha coefficient thermistors (PTCs), memory modules, identification (ID) masekete, uye zvimwe midziyo yekubatsira. Izvi zvikamu zvinoshanda tandem kugadzira yakazara yekutarisa uye yekudzivirira sisitimu inoita kuti bhatiri rishande mukati memaitiro akachengeteka.

Rimwe remabasa ekutanga erithium bhatiri ekudzivirira mabhodhi kuenderera mberi nekutarisa bhatiri yakakosha paramita mukati mekushanda kwayo. Aya ma paramita anosanganisira mamiriro ekuchaja (SoC), iyo inoratidza huwandu hwesimba rasara mubhatiri, tembiricha, voltage, kuyerera ikozvino, uye hutano hwese (SoH) hwebhatiri. Nekuenderera mberi nekutarisa aya ma paramita, bhodhi rekudzivirira rinogona kuona chero kutsauka kubva kune yakajairika mamiriro ekushanda uye kutora danho rakakodzera kudzikamisa njodzi dzinogona kuitika.

Semuyenzaniso, kana bhodhi rekudzivirira rikaona kuti bhatiri ririkuchajwa kupfuura yakachengeteka voltage miganho, rinoita kuti riite yekudzivirira yakawandisa. Muchina uyu unowanzo sanganisira kubvisa dhizaini yekuchaja kudzivirira kuwedzera kuchaja uye kudzivirira bhatiri kubva mukukuvadzwa nekuda kwekuwanda. Saizvozvo, kana magetsi ebhatiri akadonha pazasi pechimwe chikumbaridzo panguva yekubuda, zvichiratidza kuti zvinogona kubuda zvakanyanya, bhodhi rekudzivirira rinopindira kudzivirira kuwedzera kubuda uye kuchengetedza hutano hwebhatiri.

Pamusoro pekuwedzeredza uye kudzivirira kwekudzivirira, lithium bhatiri kuchengetedza mabhodhi anosanganisirawo matanho ekugadzirisa nyaya dzakadai seyakawandisa uye mapfupi maseketi. Aya maitiro ekudzivirira akakosha pakudzivirira yakawandisa ikozvino kuyerera kuburikidza nebhatiri, izvo zvinogona kutungamira mukupisa, kukuvadzwa kwemukati mezvikamu, uye kunyange kupisa kunotiza. Nekukurumidza kuona uye kupindura kune aya asina kujairika mamiriro, bhodhi rekudzivirira rinobatsira kuchengetedza kutendeseka uye kuchengetedzwa kwebhatiri system.

Pakazere, lithium bhatiri ekudzivirira mabhodhi zvinhu zvakakosha izvo zvinoita basa rakakosha mukuona kwakachengeteka uye kwakavimbika kushanda kwemabhatiri e lithium mune dzakasiyana siyana maapplication. Nekunyatso tarisisa ma paramita akakosha uye kuita matanho ekudzivirira pazvinenge zvichidikanwa, mabhodhi aya anobatsira kuwedzera kushanda kwebhatiri, kuwedzera hupenyu hwebhatiri, uye kuwedzera kuchengetedzwa kwese kwevashandisi nemidziyo zvakafanana.

Dhizaini Mafungiro eDziviriro Mabhodhi

Paunenge uchigadzira bhodhi rekudzivirira remabhatiri e lithium, akati wandei akakosha mabatiro anouya mukuita kuti ive nechokwadi chekushanda kwakakwana uye kuchengetedzeka.

Pakazere, lithium bhatiri rekudzivirira mabhodhi anoita basa rakakosha mukuona kushanda kwakachengeteka uye kwakanaka kwemabhatiri e-lithium-ion, kuvadzivirira kubva kunjodzi dzakasiyana siyana uye nekugonesa kuita kwavo uye hupenyu hurefu.

Battery Management System (BMS) yeLithium Mabhatiri

Kune mabhatiri e-high-voltage lithium, mhinduro yakanyanyisa kupfuura mabhodhi ekudzivirira inodiwa. Apa ndipo panopinda Battery Management System (BMS). BMS inopa huwandu hwakawanda hwemamwe mabasa akakosha kune akakura bhatiri mapaketi, kuve nechokwadi chekushanda kwawo kwakachengeteka uye kwakanaka.

Zvikamu zvakakosha zveBMS

1. Kudzora Module: Iyo yekudzora module ndiyo huropi hweBMS, ine basa rekutarisa nekudzora kushanda kwese kwebhatiri paki. Iyo inogadzirisa yekuchaja uye yekuburitsa maitiro, maseru kuenzanisa, uye mamwe mabasa akakosha.
2. Management System: Iyo manejimendi sisitimu inosanganisira software uye algorithms inotonga maitiro eBMS. Inovimbisa kuti bhatiri rinoshanda mukati memiganhu yakachengeteka uye rinowedzera kushanda kwayo uye hupenyu.
3. Wireless Communication Module: Iyo isina waya yekutaurirana module inobvumira iyo BMS kutaurirana nekunze zvishandiso kana masisitimu. Izvi zvinogonesa kutarisa kure uye kutonga kwebhatiri pack, pamwe nekutema data uye kuongorora.
4. Ratidza Module: Iyo yekuratidzira module inopa mushandisi interface yekutarisa mamiriro ebhatiri pack. Inogona kusanganisira zviratidzo zvebhatiri level, tembiricha, uye zvimwe zvakakosha paramita.
5. Kuunganidza Module: Iyo yekuunganidza module inounganidza data kubva kuma sensors uye zvimwe zvikamu zveBMS. Iyi data inoshandiswa neiyo control module kuita sarudzo maererano nekushanda kwebhatiri pack.

Mabasa eBMS

1. Kuyera Sero: Mune akawanda-sero bhatiri paki, maseru ega anogona kunge aine akasiyana hunyanzvi kana hunhu. Kuenzanisa kwesero kunovimbisa kuti sero rega rega rachajwa uye kuburitswa zvakaenzana, zvichiwedzera huwandu hwese uye hupenyu hwebhatiri pack.
