Kushanda kwenguva refu uye kugara kwenguva refu kwema "multi-cell lithium-ion" nema "lead-acid" mabhatiri zvinoenderana zvakanyanya nekufanana kwemaseru. Nekuda kwekusiyana kwekugadzirwa, kuora kwemakemikari, uye kupisa kuri munzvimbo, masero ega ega ari mukati me "series-connected pack" anogadzira musiyano mu voltage, internal resistance, uye kugona nekufamba kwenguva. Kusiyana uku kunogadzira "barrel effect," apo kugona kwese kwese kwepakeji kunogumira ne "weaker" sero. Panguva yekuchaja, sero rine voltage yepamusoro rinokonzeresa dziviriro yekuchaja zvakanyanya nekukurumidza, zvichisiya mamwe masero asina simba rakawanda. Panguva yekuburitsa, sero risina simba rinotanga rasvika pa "low-voltage cutoff" yaro, richicheka system yese ukuwo simba rinoshandiswa richiramba rakavharirwa mumasero ane hutano. Kusawirirana uku kunokurumidza kupera kwesimba uye kunopfupisa hupenyu hwekushanda hwepakeji yebhatiri.
Kuderedza kusawirirana uku kwekushanda, tekinoroji yekuenzanisa maseru inoshanda sechinhu chakakosha mukati memasisitimu emazuva ano emabhatiri, ichisimudzira zvakananga mashandiro epakeji yese. Kare, passive balancing yave iri indasitiri isingashande nekuda kwekureruka kwayo. Passive balancers inoshanda nekuburitsa maseru ane voltage yakakwira kuburikidza nema resistive shunts, ichibvisa simba rakawandisa sekupisa. Maitiro aya anongoshanda chete padyo nekupera kwekutenderera kwekuchaja kana kusiyana kwemagetsi eseru kuchipfuura chiyero chakati. Nekuda kweizvozvo, passive balancing inokonzera kurasikirwa kwesimba zvachose uye kugadzirwa kwekupisa kunoonekwa, ukuwo ichikundikana kutamisa chaji kwainodiwa. Nekuti inongopisa peak voltage uye haigone kudzorera simba kumasero asina simba, passive balancing inopa rutsigiro rushoma mukuwedzera hupenyu hwenguva refu hwemabhatiri anoshandiswa zvakanyanya. Active vs passive battery balancer: ndeipi iri nani? Kupindura mubvunzo uyu, iyi ongororo yehunyanzvi inoongorora maitiro ehurongwa uye mashandiro enzira dzese dziri mbiri, ichishandisa mhinduro dzepamusoro dzekuenzanisa dzakagadzirwa naChengdu Heltec Energy Technology Co., Ltd.kuongorora kukanganisa kwavo kwenguva refu pakushanda zvakanaka uye kurarama kwenguva refu.
Makanika uye Mashandiro eTekinoroji Yekuenzanisa Inoshanda
Kuenzanisa kwakasimba kunochinja kubva pakuparadza simba, uchishandisa capacitive kana inductive energy transfer kuti igovane simba zvakare mupakeji. Maitiro aya anopa zvakanakira zvakasiyana zvehunyanzvi:
● Kugoverwazve kwesimba rinoshanduka: Vagadziri vemagetsi vanoshanda vanotamisa simba zvakananga kubva kumasero ane voltage yakakwira kuenda kumasero ane voltage yakaderera. Kusiyana nemasisitimu asingashande anongotanga pakupera kwechaji, maitiro aya anoshanda nguva dzose, achitanga chero bedzi musiyano wevoltage ukaonekwa panguva yekuchaja nekubvisa.
● Kuenzanisa Kwemagetsi Kwakanyanya: Mamodule eHeltec Active Balancer anopa simba remagetsi rinosvika 5A, zvichipfuura zvakanyanya macircuits asingashande. Nekuwana chiyero chidiki chekuenzanisa chinosvika 0.01V ne ±5mV chaiyo, masisitimu aya anobvisa marara esimba ane chekuita nekupiswa kwemhepo.
● Kugona Kushanda Kwakawedzerwa: Nekugadzirisa matambudziko emasero rimwe chete, kuyera kushanda kunoderedza kushushikana kwemasero munzvimbo imwe chete. Sekureva kweongororo dzehunyanzvi neHeltec Energy, kugadzirisa uku kunochengetedza simba rese riri mukati mepakeji, zvichibvumira kugona kwakanyanya kushandiswa panguva yekubuda kwemasero.
● Dziviriro Yakasimba uye Kubatana: Mamodule aya ane mamodule ekurara akavakirwa mukati mekupisa kwakanyanya, kuburitsa mvura yakawanda, uye low-voltage sleep modes. Hardware iyi yakasimbiswa ne conformal coatings kudzivirira kubva mukuora kwezvakatipoteredza. Kune manejimendi yepamusoro, mamodheru chaiwo akaita seHT-CJ32S25A anobatanidza LCD displays kuti ionekwe panguva chaiyo, pamwe chete neWi-Fi neBluetooth connectivity kuti ionekwe kure. Rudzi rwechigadzirwa chazvino runosanganisira 8S kusvika 32S balancing boards uye specialized maintenance analyzers.
Kukosha kweKubatanidzwa kweSisitimu uye Kuvandudza Mashandiro
Module yekuyera inoshanda sechinhu chikuru chinobatanidzwa zvakananga mukati mebhatiri rakakura. Kana yaiswa zvachose pamwe chete neBattery Management System (BMS), active balancer inoramba ichiendesa mavoltage emasero ega ega kuhumwe. Kuderedza kusiyana kwemaumbirwo pakati pemasero kunoderedza kuora kwesimba risati rasvika nguva iyo inowanzoitika pasi pemaitiro epamusoro. Ruzivo rwemunda runoratidza kuti kubatanidza active balancer kunogona kudzoreredza pakati pe10% ne20% yesimba rinoshanda rebhatiri iro ringadai rakavharirwa kunze nekudonha kwesimba remagetsi remasero rimwe chete.
Kuti bhatiri riwedzere kushanda zvakanaka, hardware iyi inoshanda pamwe chete nezvishandiso zvekuongorora. Kana yakabatana nezviyedzo zvebhatiri zvine hungwaru uye mita dzekudzivirira mukati kubva kuChengdu Heltec Energy Technology Co., Ltd., vashandisi vanogona kugadzira nzira yakakwana yekuchengetedza nekuongorora. Zvishandiso zvekuongorora zvinoona masero akaora anoratidza kudzivirira mukati kwakanyanya, nepo hardware inoshanda ichigadzirisa tambo yesero yasara, ichivandudza kugadzikana kwechimiro uye kuwedzera hupenyu hwebasa renetwork yese yebhatiri.
Maitiro Ekushandisa Akakosha
Kudiwa kwe high-current active balancing kuri kuwedzera muzvikamu zvakasiyana-siyana zvemaindasitiri nemabhizimisi zvinoda simba. Mumasisitimu ekuchengetera simba emotokari dzekuvaraidza (RV) uye mumabhanga ekuchengetera simba rezuva ekugara, active balancing inoita kuti mabhangi makuru, akawanda akafanana arambe aine mazinga akafanana panguva yekuchaja nekukurumidza kwezuva uye inverter inoburitsa simba rakawanda. Muchikamu chemagetsi ekufambisa—kusanganisira mavhiri maviri emagetsi, zvikepe zvinotakura, uye mota dzisina vanhu (UAVs)—active balancing inochengetedza kurongeka kwenzvimbo uye inodzikamisa kutumirwa kwesimba pasi pemitoro yekukurumidzira kamwe kamwe. Masimba emagetsi emaindasitiri, ma uninterruptible power supplies (UPS), uye masisitimu ekuchengetedza matelecom anovimbawo zvakanyanya ne active balancing kuchengetedza kugadzirira kwesystem uye kudzivirira kutadza kushanda kwemasero kamwe kamwe panguva yekudzima kwegrid kwakakosha. Muchiitiko chega chega, kubatanidzwa kwe ma matching capacity testers uye resistance meter kunopa vashandisi zvivakwa zvekuchengetedza zvekudzivirira zvakakwana.
Maitiro eR&D Infrastructure uye Magadzirirwo
Kuvimbika kwemagetsi ekugadzirisa magetsi zvinoenderana zvakanyanya nekunyatsogadzirwa kwawo uye kuomarara kwekusimbisa kwawo mainjiniya. Heltec Energy ine hunyanzvi hwakabatana hwekugadzira nekugadzira zvinhu panzvimbo yayo yakatsaurirwa kugadzira muChengdu. Fekitori iyi inoshandisa michina yeYamaha SMT inokwanisa kugadzira zvinhu zvinosvika 800 kusvika 1,000 pazuva, zvichiita kuti kugadzirwa kuenderane uye kuti zvinhu zvikwanise kutengeswa.
Chikamu cheinjiniya chine mainjiniya ekutsvaga nekuvandudza anopfuura makumi matatu akatarisana nemagetsi emagetsi, dhizaini yefirmware, uye kuongororwa kwemakemikari emagetsi. Iyi fomati yehunyanzvi inobvumira kambani kuwana zvitupa zvekutevedzera mitemo yepasi rose, kusanganisira CE, FCC, uye WEEE standards. Kuti itsigire kugoverwa kwepasi rose uye kuderedza nguva yekutungamira kune vagadziri vepasi rese nevanobatanidza masisitimu, matura ekuchengetera zvinhu kunze kwenyika anochengetwa munzvimbo huru, kusanganisira North America, Europe, Russia, neBrazil. Maitiro akazara eFAQ anotsigira zvibvumirano zvebasa zveOEM neODM zvinochinjika, zvichigonesa vatengi vepasi rese kuwana magadzirirwo ekuenzanisa akagadzirirwa mashandisirwo chaiwo emaindasitiri.
Mhedziso
Tekinoroji yekuenzanisa inoshanda inopa mukana wakakura pane kungoparadzira simba chete nekuvandudza mashandiro esimba uye kuchengetedza hupenyu hwemasero. Sechinhu chikuru mukati memazuva ano emasero akawanda, ma "active balancers" anoderedza mhedzisiro yekusafanana kwemasero uku achichengetedza simba rese re "pack". Kusarudza "active balancing module" yakakodzera inoenderana nema "pack architectures" chaiwo kunobatsira kuvandudza mashandiro ekushanda kwenguva refu.
