Chii Chinoita Lithium Mabhatiri Akangwara?

Munyika yemabhatiri, kune mabhatiri ane monitoring circuitry uyezve kune mabhatiri asina.Lithium inoonekwa seyakangwara bhatiri nekuti ine yakadhindwa yedunhu bhodhi inodzora kuita kwe lithium bhatiri.Kune rimwe divi, yakajairwa yakavharwa lead acid bhatiri haina chero bhodhi rekutonga kuti riwedzere kuita kwayo.?

Mune a smart lithium bhatirikune 3 matanho ekutanga ekutonga.Yekutanga nhanho yekudzora iri nyore kuenzanisa iyo inongowedzera ma voltages emaseru.Yechipiri nhanho yekutonga ndeye inodzivirira yedunhu module (PCM) inodzivirira maseru epamusoro / yakaderera voltages uye mafungu panguva yekuchaja uye kuburitsa.Yechitatu nhanho yekutonga ndeye bhatiri manejimendi system (BMS).Iyo BMS ine zvese zvinogoneka zvechiyero chedunhu uye inodzivirira yedunhu module asi ine humwe hunyanzvi hwekugonesa kushanda kwebhatiri pamusoro pehupenyu hwayo hwese (sekutarisa mamiriro ekubhadhara uye mamiriro ehutano).

LITHIUM BALANCING CIRCUIT

Mubhatiri rine bancing chip, chip chinongoenzanisa magetsi ega ega maseru ari mubhatiri ichichaja.Bhatiri inoonekwa seyakaenzana kana ese maseru voltages ari mukati mediki kushivirira kune mumwe nemumwe.Kune marudzi maviri ekuenzanisa, kushanda uye kungoita.Active balancing inoitika nekushandisa maseru ane ma voltages akakwira kuchaja maseru ane ma voltages epasi zvichidzikisa musiyano wevoltige pakati pemaseru kusvika maseru ese anyatsoenderana uye bhatiri razara.Passive balancing, iyo inoshandiswa pane ese Power Sonic lithium mabhatiri, ndipo apo sero rega rega rine chinopikisa chiri muparallel chinobatidzwa kana cell voltage iri pamusoro pechikumbaridzo.Izvi zvinodzikisira chaji iripo mumaseru ane voltage yakakwira zvichibvumira mamwe maseru kuti abate kumusoro.

Sei kuenzanisa kwesero kuchikosha?Mumabhatiri e-lithium, pakarepo kana iyo yakaderera-voltage cell ichirova discharge voltage yakagurwa, inovhara bhatiri rese.Izvi zvinogona kureva kuti mamwe masero ane simba risina kushandiswa.Saizvozvo, kana maseru asina kuenzana pakuchaja, kuchaja kunozovhiringwa kana sero rine simba repamusoro rasvika pamagetsi akachekwa uye asiri ese maseru achachajwa zvizere.

Chii chakaipa ipapo?Kugara uchichaja nekuburitsa bhatiri risina kuenzana kunoderedza huwandu hwebhatiri nekufamba kwenguva.Izvi zvinoreva zvakare kuti mamwe maseru achachajiwa zvakazara, uye mamwe haaite, zvichizokonzera bhatiri risingazombosviki 100% State of Charge.

Dzidziso ndeyokuti masero akaenzana ose anobuda pamwero wakafanana, uye naizvozvo akachekwa-kubviswa pamagetsi akafanana.Izvi hazvisi chokwadi nguva dzose, saka kuva nebancing chip kunovimbisa kuti pakuchaja, masero ebhatiri anogona kunyatsoenderana kuchengetedza huwandu hwebhatiri uye kuti inyatsochajiwa.

LITHIUM PROTECTIVE CIRCUIT MODULE

A Protective Circuit Module ine chiyero chedunhu uye chekuwedzera chedunhu chinodzora maparamendi ebhatiri nekudzivirira kubva pakuchaja zvakanyanya uye kuburitsa zvakanyanya.Inoita izvi nekutarisa zvazvino, voltages, uye tembiricha panguva yekuchaja uye kuburitsa uye nekuzvienzanisa neyakatemerwa miganhu.Kana chero imwe yemasero ebhatiri ikarova imwe yeaya maganhuriro, bhatiri rinodzima kuchaja kana kuburitsa zvinoenderana kusvikira nzira yekuburitsa yasangana.

Pane nzira shoma dzekudzosera kuchaja kana kuburitsa kumashure mushure mekunge dziviriro yabviswa.Yekutanga inguva yakavakirwa, uko timer inoverengera kwechinguva chidiki (semuenzaniso, 30 masekondi) uye wozoburitsa dziviriro.Iyi timer inogona kusiyanisa kune imwe neimwe dziviriro uye ndeye imwe-level dziviriro.

Yechipiri ndeye kukosha kwakavakirwa, uko kukosha kunofanirwa kudonha pasi pechikumbaridzo kuti isunungurwe.Semuenzaniso, iwo magetsi ese anofanirwa kudonha pazasi 3.6 volts pasero kuitira kuti yakawandisa-chaji dziviriro iburitswe.Izvi zvinogona kuitika pakarepo kana mamiriro ekusunungurwa asangana.Zvinogona kuitika zvakare mushure menguva yakatarwa.Semuenzaniso, ma voltages ese anofanirwa kudonha pazasi 3.6 volts pasero nekuda kwekudzivirira-kuchaja uye inofanirwa kugara pasi peiyo muganhu kwemasekonzi matanhatu PCM isati yaburitsa dziviriro.

Chechitatu ibasa rakavakirwa, apo chiito chinofanira kutorwa kusunungura dziviriro.Semuenzaniso, chiito chinogona kunge chiri kubvisa mutoro kana kuisa mutero.Sezvakangoita kukosha-kwakavakirwa kudzivirira kuburitswa, kuburitswa uku kunogona kuitikawo nekukasira kana kuve nenguva.Izvi zvinogona kureva kuti mutoro unofanirwa kubviswa mubhatiri kwemasekonzi makumi matatu dziviriro isati yaburitswa.Pamusoro penguva uye kukosha kana chiitiko uye nguva-yakavakirwa kuburitswa, zvakakosha kuziva kuti idzi nzira dzekuburitsa dzinogona kuitika mune mamwe masanganiswa.Semuenzaniso, iyo over-discharge release voltage inogona kunge iri kana maseru adonha pasi pe 2.5 volts asi kuchaja kwemasekonzi gumi kunodiwa kuti usvike pamagetsi iwayo.Rudzi urwu rwekuburitswa runovhara ese matatu marudzi ekuburitswa.

Isu tinonzwisisa kuti pane zvakawanda zvinhu zvinopinda pakusarudza zvakanakisa lithium bhatiri, uye nyanzvi dzedu dziripo kuti dzibatsire.Kana iwe uine mimwe mibvunzo nezve kusarudza bhatiri rakakodzera rekushandisa kwako, ndapota inzwa wakasununguka kusvika kune mumwe wenyanzvi dzedu nhasi.
