Iyo yakakosha nyaya mukugadzirisa bhatiri uye lithium bhatiri pack yekuwedzera maapplication ndeyekuti maviri kana anopfuura seti yelithium bhatiri mapaketi anogona kubatanidzwa zvakananga munhevedzano kana yakafanana. Nzira dzekubatanidza dzisina kunaka hadzingokonzeredzi kudzikira kwekuita kwebhatiri, asi zvakare dzinogona kukonzera njodzi dzekuchengetedza dzakadai semapfupi maseketi uye kuwandisa.

Tevere, isu tichaongorora zvakadzama nzira dzakakodzera uye matanho ekubatanidza lithium bhatiri mapaketi kubva kune ese ari maviri akafanana uye akatevedzana maonero, akasanganiswa nekushandiswabhatiri bvunzo uye kugadzirisa zviridzwa.
Parallel yekubatanidza kwe lithium bhatiri paki: kukoshesa kwakaenzana pamamiriro uye kuchengetedzwa
Kubatana kwakafanana kwelithium bhatiri packs inogona kukamurwa kuita mamiriro maviri, iyo musimboti iri pakuti bhatiri pack paramita inopindirana uye kana matanho ekudzivirira anodiwa akatorwa. Paunenge uchitonga iyo parameter yebhatiri pack, iyo lithiumbhatiri testerinogona kunyatso kuyera data senge voltage uye yemukati kuramba, ichipa hwaro hwesainzi hwechirongwa chekubatanidza
(1) Yakananga parallel yekubatanidza kana paramita ichienderana
Kana iyo voltage, huwandu, kupikisa kwemukati, sero modhi uye zvimwe zvinongedzo zvemaseti maviri e lithium bhatiri packs zvakangofanana, kushanda kwakafanana kunogona kuitwa zvakananga. Semuenzaniso, kushandisa lithium battery tester kuona seti mbiri dze lithium bhatiri packs ine imwechete 4-series chimiro uye zita remagetsi e12V, kana yazara chaji uye ine simba rimwechete, batanidza danda ravo rose rakanaka kune yakazara yakanaka danda uye yakazara isina kunaka danda kuti upedze kuenderana kwakafanana. Izvo zvinofanirwa kusimbiswa kuti bhatiri paki yega yega inofanirwa kuve neyakazvimiririra yekudzivirira bhodhi kuti ive nechokwadi chekuwandisa, kuwandisa, uye mapfupi-sekete kuchengetedza mabasa ebhatiri. Mukuwedzera, mushure mokunge kubatanidzwa kwapera, zvakakosha kushandisa lithiumbhatiri testerkuti utarise zvakare maparamendi kuti ive nechokwadi chekushanda kwakagadzikana kweiyo parallel yakabatana bhatiri paki. .
(2) Parallel scheme kana paramita isingaenderane
Muchiitiko chaicho chekugadzirisa, zvinowanzoitika kusangana nemabheji ebhatiri anoumbwa nezvikwata zvakasiyana-siyana zvemasero, kunyange kana zita remagetsi rakafanana (se12V), pane kusiyana kwehutano (50Ah uye 60Ah) uye kupikisa kwemukati. Mune ino kesi, yakananga parallel yekubatanidza ichaunza njodzi huru - kana ma voltages emapoka maviri ebhatiri akasiyana (senge 14V uye 12V), iyo yakakwira-voltage bhatiri boka rinokurumidza kuchaja iro rakaderera-voltage bhatiri boka. Zvinoenderana neMutemo weOhm, kana kupikisa kwemukati kweyepasi-voltage bhatiri paki iri 2 Ω, iyo pakarepo mutual kuchaja ikozvino inogona kusvika ku1000A, izvo zvinogona kuita kuti bhatiri ridziye, kubhuroka, kana kutobata moto. .
Kutarisana nemamiriro ezvinhu aya, midziyo yekudzivirira yakafanana inofanirwa kuwedzerwa:
Sarudza bhodhi redziviriro rine yakavakirwa-mukati ikozvino inodzikamisa basa: Mamwe epamusoro-ekupedzisira mabhodhi ekudzivirira ane akafanana azvino anodzikamisa maitiro, ayo anogona otomatiki kudzikamisa mutual kuchaja ikozvino mukati meyakachengeteka renji. Paunosarudza bhodhi rinodzivirira, lithiumbhatiri kugadzirisa mudziyoinogona kushandiswa kutarisa kana basa rayo rakajairika. .
Kuisa yekunze parallel yazvino yekumisikidza module: Kana iyo bhodhi yekudzivirira isina basa iri, imwe nyanzvi yazvino yekumisikidza module inogona kugadziridzwa kudzora iripo padanho rinonzwisisika uye kuve nechokwadi chekubatana kwakachengeteka. Mushure mekuisa iyo yazvino yekumisikidza module, zvinodikanwa kushandisa lithium bhatiri tester kutarisa shanduko iripo uye kuona kushanda kweiyo module.
Series yekubatanidza yelithium bhatiri paki: yakakwirira zvinodiwa uye kugadzirisa
Kuenzaniswa nekubatana kwakabatana, iyo yakatevedzana yekubatanidza yelithium bhatiri mapaketi inoda zvakanyanya kuomesesa kuenderana zvinodiwa zvebhatiri pack. Kana yakabatana munhevedzano, inogona kufananidzwa nehurongwa hwekuungana kwemasero ebhatiri emukati mubhatiri pack, iyo inoda zvakanyanya kuenderana paramita senge voltage, kugona, kupikisa kwemukati, uye mwero wekuzviburitsa wega pakati pemabhatiri maviri mapaketi. Zvikasadaro, kusaenzana kwemagetsi kugovera kunogona kuitika, kunowedzera kuchembera kwemabhatiri emapaketi asingaite zvakanaka. Pakusarudza akakodzera bhatiri mapaketi, lithiumvanoedza bhatiriinogona kuona nekukurumidza uye nemazvo akasiyana ma parameter, achinatsiridza mashandiro ekuongorora. .
Pamusoro pezvo, huwandu hwevoltage mushure mekubatanidza nhevedzano ihuwandu hwevoltage yeboka rimwechete (seseti maviri emabhatiri e12V akabatana munhevedzano ye24V), izvo zvinoisa zvinodikanwa zvakanyanya pane inomira voltage kukosha kweMos chubhu mubhodhi rekudzivirira. Mabhodhi edziviriro akajairwa anowanzo kukodzera chete kumapoka emagetsi ega. Kana ichishandiswa munhevedzano, inowanzodikanwa kugadzirisa mabhodhi ekudzivirira akakwira-voltage kana kusarudza nyanzvi yebhatiri manejimendi masisitimu (BMS) anotsigira akawanda tambo kuti ive nechokwadi chekuchengetedza uye kugadzikana kweakateedzana akabatanidza bhatiri paki panguva yekuchaja nekuburitsa. Iyo lithium bhatiri yekugadziridza mudziyo inogona kuita basa rekugadzirisa uye kugadzirisa matambudziko pamabhodhi ekudzivirira akajairwa uye BMS kuve nechokwadi chekushanda kwavo kwakajairika.
Mazano Ekuchengetedza uye Mazano Anoshanda
Random yakatevedzana parallel yekubatanidza inorambidzwa zvachose: Lithium bhatiri mapaketi emhando dzakasiyana uye mabhechi haabvumidzwe kubatana zvakananga pasina kurapwa nekuda kwekusiyana kwebatiri cell kemikari maitiro uye maitiro. .
Kugara uchiongorora uye kugadzirisa: Iyo parallel system inoda kutarisa bhatiri pack voltage mwedzi wega wega, uye kana mutsauko wakapfuura 0.3V, inoda kubhadhariswa zvakasiyana kuti ienzanise; Zvinokurudzirwa kushingaira kuenzanisa iyo yakatevedzana system kuburikidza neBMS kota yega yega. .
Sarudza zvigadzirwa zvepamusoro-soro: Izvo zvinodiwa kushandisa mabhodhi ekudzivirira uye BMS yakasimbiswa neUN38.3, CE, nezvimwewo. Iyo yekubatanidza waya inofanira kusarudzwa neakakodzera dhayamita yetambo maererano nemutoro wezvino kuti udzivise kupisa kunokonzerwa nekurasikirwa kwetambo. .
Iwo akateedzana kushanda kwelithium bhatiri mapaketi anofanirwa kuve akavakirwa pakuchengetedza, achinyatso kudzora kuwirirana kwebhatiri pack paramita, uye kushandira pamwe nehunyanzvi hwekudzivirira michina. Kubata aya mapoinzi akakosha hakungogone kuvandudza mashandiro ekugadzirisa bhatiri, asi zvakare kuve nechokwadi chekushanda kwakasimba kwenguva refu kwe lithium bhatiri mapaketi.
