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 akateedzana maonero.
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. .
(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, seti mbiri dze lithium battery packs dzine 4-series structure uye nominal voltage ye 12V, kana yazara yakazara uye ine simba rimwechete, inogona kubatanidzwa mukufanana nekubatanidza danda ravo rose rakanaka kune danda rakanaka uye danda risina kunaka kune danda rose risina kunaka. Izvo zvinofanirwa kusimbiswa kuti bhatiri paki yega yega inofanirwa kuve neyakazvimiririra yekudzivirira bhodhi kuti ive nechokwadi chekuwandisa, kuwandisa, uye mapfupi-sekete kuchengetedza mabasa ebhatiri. .
(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. .
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.
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. .
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.
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.
