Kune varidzi, vashandi, uye mainjiniya vanotarisira masisitimu emabhatiri e lithium, mubvunzo unowanzo buda: "Ko paki itsva yebhatiri inoda module yekuwedzera yekuenzanisa here?" Kunyange zvazvo masero akaenzana nefekitori achiwanzo vimbika pakutanga kwehupenyu hwavo, hutano hwenguva refu uye kushanda kwakasimba kwepaki chero ipi zvayo yakabatana zvinoenderana zvakanyanya nekuchengetedza kugadzikana kwakaringana kwemagetsi.Active Balancerinoshanda semari inoshanda zvakanyanya uye isingadhuri kuchengetedza kuenderana uku muhupenyu hwese hwekushanda kwemidziyo. Nekushandisa ruzivo rwechokwadi rwehunyanzvi uye data reinjiniya kubvaHeltec Energy (Chengdu Heltec Energy Technology Co., Ltd.)Chinyorwa chino chinoongorora kuti sei tekinoroji yekuenzanisa zvinhu iri kukurumidza kuva chinhu chakakosha pakuvandudza mashandiro ebhatiri, kuchengetedzeka kwesystem, uye kugara kwenguva refu mukushandiswa kwesimba kwemazuva ano.
Mubvunzo 1: Sei Mapaketi eLithium Battery Aine Kusawirirana kweVoltage?
Paketi yega yega yebhatiri re lithium, pasinei nekuti rakatanga sei kugadzirwa, inogona kukanganiswa ne "battery barrel effect." Izvi zvinoitika nekuti hapana masero maviri akafanana zvakakwana. Kusiyana kudiki, kuripo mukugadzirwa kwemakemikari emukati, kushivirira kwekugadzirwa, mwero wekuzviburitsa wega, uye kunzwa kwekushanduka-shanduka kwekupisa kwekunze kwakajairika kune ese masero e lithium-ion ne lithium iron phosphate (LiFePO₄).
Sezvo paki yebhatiri ichigara ichichinjana nekuchaja nekuburitsa zvinhu, misiyano iyi midiki inoungana uye inopararira. Kana sero rine simba rakakwirira zvishoma kana resistance yemukati yakaderera yasvika pamuganho wayo wepamusoro wemagetsi nekukurumidza kupfuura vavakidzani vayo, rinogona kukonzera kuchekwa kwekuchaja nguva isati yakwana kana kuvharwa kwekudzivirira. Kusiyana neizvi, panguva yekuburitsa zvinhu, sero risina simba rinogona kutanga rasvika pamuganho wevoltage yakaderera. Nekufamba kwenguva, kusawirirana uku kunowedzera. Sero risina simba—"bako pfupi" riri mubharero—rinonyatso raira uye rinoderedza simba rinoshanda repakeji rese, zvichimanikidza sisitimu kumira kushanda kunyangwe masero asara achiri kubata simba rakawanda rakachengetwa.
Mubvunzo wechipiri: Kuenzanisa Zvinhu Zvakakwana Here? Sei Tichifanira Kukurudzira Kuenzanisa Zvinhu Zvine Basa?
Kuti vaderedze matambudziko aya akajairika, masisitimu mazhinji echinyakare anovimba ne passive balancing. Nzira iyi inowanzo shandisa ma resistors kubvisa simba rakawandisa remasero ane voltage yakawanda sekupisa kusvika voltage yavo yafanana nevamwe vese veboka. Kunyange zvazvo passive balancing ichidhura zvishoma, ine muganho: inoshanda chete nekubvisa simba, izvo hazviiti kuti sisitimu yese iwedzere kugona kwayo, uye inogadzira kupisa kusingakoshi, izvo zvinogona kukanganisa hutano hwebhatiri munzvimbo dzine tembiricha yakakwira.
Kusiyana neizvi, Active Balancer—yakadai semamodule epamusoro akagadzirwa neHeltec Energy—inoshandisa matekiniki ekufambisa simba akanyanya kunaka pane kuaparadzira. Ichishandisa ma super-capacitor anoshanda zvakanyanya kana kuti transformer push-pull rectification feedback, zvishandiso izvi zvinofambisa simba kubva kumasero ane voltage yakakwira kuenda kune ane voltage yakaderera. Nzira iyi inoshanda zvakanyanya nekuti inochengetedza simba rinokosha pane kuritambisa. Mayuniti epamusoro, kusanganisira ayo akagadzirwa neChengdu Heltec Energy Technology Co., Ltd., anopa zvinhu zvakawanda: haadi musiyano chaiwo wevoltage kuti atange kushanda, anoshanda pamwe chete mupakeji yese, uye anogona kupa ma currents akasimba anotangira pa 0 kusvika 10A zvichienderana nekusiyana kwekumanikidzwa kwakaonekwa. Kugona uku kwehunyanzvi kunobvumira kugadziriswa kwevoltage chaiyo, chaiyo, kazhinji kuchizadzisa kururama mukati me 0.01V.
Mubvunzo wechitatu: Kuisa Active Balancer Module Kunovandudza Sei Kushanda Kwese Kwepakeji?
Kubatanidza module inoshanda inogadzirisa bhatiri zvinobudirira kunoshandura bhatiri kubva muunganidzwa wemasero ega ega, anogona kusiyana kuita sisitimu yesimba inogara kwenguva refu. Kubatsira kukuru kweHeltec Energy 5A active balancer kuri mukukwanisa kwayo kubvisa matambudziko anokonzerwa nekuora kwemasero ega ega. Nekuona kuti sero rega rega riri mukati me8S kusvika ku32S configuration rinogara mukati me voltage range yakasimba, yakagadziriswa, module iyi inobvumira sisitimu yekutarisira bhatiri kushandisa simba rakazara repaketi zvinobudirira.
Maitiro aya ekugadzirisa anoenderera mberi anowedzera hupenyu hwebasa repakeji nekudzivirira kushushikana kwakadzika kwemasero asina simba. Uyezve, mamodule aya akagadzirirwa kutsungirira munzvimbo dzinoda maindasitiri nedzekufamba. Mayunitsi mazhinji ane zvinhu zvinodzivirira zvakaita sekudzivirira kupisa kwakanyanya, nzira dzekurara dzine voltage shoma kudzivirira kubuda kwemhepo zvakanyanya panguva dzisina basa, uye machira ekudzivirira matatu anodzivirira kupisa anopa kudzivirira kwakakosha kubva kuhunyoro, guruva, uye zvinhu zvinoparadza. Nekuchengetedza mazinga emagetsi akafanana, kushushikana pamasero ega ega kunoderedzwa, zvichikonzera kushanda kwakachengeteka, kwakasimba, uye kwakavimbika mumashandisirwo akasiyana-siyana, kusanganisira mota dzemagetsi, masisitimu ekuchengetera simba asingachinji, uye magetsi emaindasitiri.
Mubvunzo wechina: Mumamiriro ezvinhu api anodiwa kana kuti anononoka kuiswa?
Kusarudza kana kuisa active balancer kunowanzoenderana nekushandiswa kwacho, kushushikana kwezvakatipoteredza, uye mashandisirwo ehurongwa hwebhatiri. Kune masisitimu anowanzo kuve nekushushikana kukuru kwekushanda, senge ma pack ekuchengetedza simba ane 4S kana ma series akakura, ma pack emabhatiri ekare uko maseru angave akagadzira ma profiles akasiyana ekuora, kana ma setup anowanzo shanda ne persistent voltage differentials anodarika 30mV, kuiswa kwacho kunokurudzirwa zvikuru. Izvi zvinobatsirwa nekukurumidza kubva mukugadzikana nekudzivirirwa kunopihwa ne balancing module. Kusiyana neizvi, kana sisitimu ikashandisa cell pack itsva, yakanyatsoenderana uye ichishanda pasi pema shorty charge-discharge cycles, shallow charge-discharge cycles, kuiswa nekukurumidza kungasave kwakakosha zvakanyanya, kunyangwe kutarisa kweproactive kuchiri kukurudzirwa zvakanyanya sezvo pack ichikura.
Mhedziso
Kugadzikana kwebhatiri re lithium kwakakosha pakushanda kwayo kwenguva refu uye kushanda zvakanaka kwemari. Nekugadzirisa zvikonzero zvinokonzera kusawirirana kwemasero kuburikidza nekufambisa simba zvakanyanya, tekinoroji inopihwa neHeltec Energy inobatsira vashandisi kuwedzera mari yavo, kuvandudza kuchengetedzeka kwekushanda, uye kuwedzera hupenyu hwekushanda kwemidziyo yavo. Ingave kuchengetedza ngarava dzekutengeserana dzehunyanzvi kana sisitimu yekuchengetera simba yakazvimirira, kutonga kwemagetsi nekukurumidza inzira yakajeka uye inoshanda yekuwana hutano hwakanaka hwebhatiri.
Kune avo vanoda kunzwisisa zvinodiwa zvekuenzanisa bhatiri rakasiyana kana vanofarira ruzivo rwakadzama rwehunyanzvi hwemagadzirirwo akasiyana-siyana emasero, zviwanikwa zvakawanda uye ruzivo rwechigadzirwa zvinogona kuwanikwa pahttps://www.heltec-energy.com/
