Dambudziko guru mukugadzirisa mabhatiri uye kuwedzera mabheteri e lithium nderekuti mabheteri maviri kana anopfuura e lithium anogona kubatana zvakananga here mu series kana parallel. Nzira dzisiri dzekubatanidza hadzingogumiri pakudzikira kwekushanda kwebhatiri, asiwo dzinogona kukonzera njodzi dzekuchengetedza dzakadai se short circuits uye overheating. Tevere, tichaongorora zvakadzama nzira dzakakodzera uye matanho ekudzivirira ekubatanidza mabheteri e lithium kubva pamaonero akafanana uye akatevedzana.
Kubatana kwakafanana kwe lithium battery pack: kusimbiswa kwakaenzana pamamiriro ezvinhu nedziviriro
Kubatana kwakafanana kwemapaketi emabhatiri e lithium kunogona kukamurwa kuita mamiriro maviri, ayo ari pakati pekuti parameters dzepaketi yebhatiri dzinoenderana here uye kana matanho ekudzivirira anodiwa akatorwa.
(1) Kubatana kwakananga kwakafanana kana ma parameters achienderana
Kana voltage, kugona, resistance yemukati, modeli yesero nezvimwe zvinodiwa zvemaseti maviri e lithium battery packs zvakafanana, kushanda kwakafanana kunogona kuitwa zvakananga. Semuenzaniso, seti mbiri dze lithium battery packs dzine chimiro che 4-series uye nominal voltage ye 12V, kana dzazara uye dzine voltage imwechete, dzinogona kubatanidzwa pamwe chete nekubatanidza total positive pole yavo ku total positive pole uye total negative pole ku total negative pole. Zvinofanira kusimbiswa kuti bhatiri rega rega rinofanira kunge rakashongedzwa nebhodhi rekudzivirira rakazvimirira kuti rive nechokwadi chekuti bhatiri rinoshandisa overcharge, overdischarge, uye short-circuit protection.
(2) Purogiramu yakafanana kana ma parameter asingawirirani
Mukugadzirisa chaiko, zvakajairika kusangana nemapaketi emabhatiri ane mabheti akasiyana emasero, kunyangwe voltage yemhando yepamusoro yakafanana (senge 12V), pane musiyano muhukuru (50Ah ne60Ah) uye resistance yemukati. Muchiitiko ichi, kubatana kwakananga kwakafanana kuchaunza njodzi huru - kana mavoltage emapoka maviri emabhatiri akasiyana (senge 14V ne12V), boka remabhatiri rine voltage yepamusoro richachaja nekukurumidza boka remabhatiri rine voltage shoma. Sekureva kweOhm's Law, kana resistance yemukati yebhatiri rine voltage shoma iri 2 Ω, instantaneous mutual charging current inogona kusvika 1000A, izvo zvinogona kukonzera kuti bhatiri ripise, riputike, kana kutobata moto.
Kuti ugadzirise mamiriro ezvinhu aya, zvishandiso zvekudzivirira zvinoenderana zvinofanirwa kuwedzerwa:
Sarudza bhodhi rekudzivirira rine basa rekudzivirira magetsi rakavakirwa mukati: Mamwe mabhodhi ekudzivirira emhando yepamusoro ane hunhu hwekudzivirira magetsi akaenzana, izvo zvinogona kuganhurira otomatiki simba rekuchaja magetsi mukati menzvimbo yakachengeteka.
Kuisa module yekuganhurira magetsi inofanana neyakajairika: Kana bhodhi rekudzivirira risina basa iri, module yekuganhurira magetsi yehunyanzvi inogona kugadzirwa kuti idzore magetsi padanho rakanaka uye ive nechokwadi chekuti kubatana kwakachengeteka.
Kubatana kwakatevedzana kwe lithium battery pack: zvinodiwa zvakanyanya uye kugadzirisa
Zvichienzaniswa nekubatana kwakafanana, kubatana kwakabatana kwema lithium battery packs kunoda kuenderana kwakasimba kwebhatiri. Kana yakabatana mumutsara, inogona kufananidzwa nemaitiro ekuunganidza ma cell ebhatiri emukati mubhatiri, izvo zvinoda ma parameter akafanana akadai se voltage, capacity, internal resistance, uye self discharge rate pakati pema bhatiri maviri. Zvikasadaro, kugoverwa kwemagetsi kusina kuenzana kunogona kuitika, zvichikurumidzisa kukwegura kwema bhatiri asingashande zvakanaka.
Pamusoro pezvo, huwandu hwemagetsi mushure mekubatana kweseji hunosanganisira huwandu hwemagetsi eboka rimwe chete (senge seti mbiri dzemabhatiri e12V akabatana museji ye24V), izvo zvinoisa zvinodiwa zvakanyanya pahuwandu hwemagetsi ekudzivirira eMos tube mubhodhi rekudzivirira. Mabhodhi ekudzivirira akajairwa anowanzo kukodzera mapoka emagetsi ega ega chete. Kana achishandiswa museji, zvinowanzo dikanwa kugadzirisa mabhodhi ekudzivirira ane voltage yakawanda kana kusarudza masisitimu ekutarisira mabhatiri ehunyanzvi (BMS) anotsigira tambo dzakawanda kuti ave nechokwadi chekuchengetedzeka uye kugadzikana kweseji yebhatiri yakabatana panguva yekuchaja nekuburitsa.
Mazano Ekuchengetedza uye Mazano Anoshanda
Kubatana kwakafanana kweseji kwakatarwa kunorambidzwa zvachose: Mapaketi emabhatiri eLithium emhando dzakasiyana uye mabheti haatenderwe kubatanidzwa zvakananga pasina kurapwa nekuda kwekusiyana kwehunhu hwemakemikari emasero ebhatiri uye maitiro.
Kuongorora nekugadzirisa nguva dzose: Sisitimu iyi inofanirwa kutarisa voltage yebhatiri mwedzi wega wega, uye kana mutsauko wacho ukadarika 0.3V, inofanira kuchajwa zvakasiyana kuti ienzaniswe; Zvinokurudzirwa kuti sisitimu iyi ienzaniswe kuburikidza neBMS kota yega yega.
Sarudza zvishongedzo zvemhando yepamusoro: Zvakakosha kushandisa mabhodhi ekudzivirira uye BMS zvakabvumidzwa neUN38.3, CE, nezvimwewo. Waya inobatanidza inofanira kusarudzwa ine dhayamita yakakodzera yewaya zvichienderana nemutoro wepari zvino kudzivirira kupisa kunokonzerwa nekurasikirwa kwewaya.
Kushanda kwakafanana kwemapaketi emabhatiri e-lithium kunofanirwa kunge kwakavakirwa pakuchengetedza, kudzora zvakanyanya kuenderana kwemaparamita emapaketi emabhatiri, uye kushanda pamwe chete nemidziyo yekudzivirira yehunyanzvi. Kuziva zvinhu izvi zvakakosha hakungogone chete kuvandudza mashandiro ekugadzirisa mabhatiri, asiwo kuve nechokwadi chekuti mapaketi emabhatiri e-lithium anogara kwenguva refu.
