Nhanganyaya：
Mabhatiri eLithium ari kwese kwese muhupenyu hwedu. Mabhatiri edu efoni nemabhatiri emotokari dzemagetsi zvese zviripomabhatiri e lithiamu, asi unoziva here mamwe mazwi ekutanga ebhatiri, mhando dzemabhatiri, uye basa uye musiyano wemabhatiri akatevedzana uye kubatana kwakafanana? Ngationgororei ruzivo rwemabhatiri neHeltec.
Izwi rekutanga remabhatiri e lithiamu
1) C-rate
Inoreva chiyero chemagetsi nehukuru hwebhatiri re lithium panguva yekuchaja nekuburitsa simba. Inotsanangura kuti bhatiri rinogona kuchajwa nekuburitswa nekukurumidza sei. Mwero wekuchaja nekuburitsa simba haufanani. Semuenzaniso:
1C: buritsa bhatiri zvizere mukati meawa imwe (chaja yakazara)
0.2C: buritsa bhatiri zvizere mukati memaawa mashanu (chaja yakazara)
5C: buritsa bhatiri zvizere mukati memaawa 0.2 (chaja yakazara)
2) Kugona
Huwandu hwemagetsi akachengetwa mubhatiri re lithiamuChigadziko chacho i mAh kana Ah.
Kana zvabatanidzwa nemutengo, semuenzaniso, kana bhatiri riri 4800mAh uye mwero wekuchaja uri 0.2C, zvinoreva kuti zvinotora maawa mashanu kuti bhatiri rive rakachajwa zvizere kubva risina chinhu (tisingateereri danho rekutanga kuchaja kana bhatiri rakaderera).
Kuchaja kwazvino ndekwekuti: 4800mA*0.2C=0.96A
3) Sisitimu yekutarisira mabhatiri eBMS
Sisitimu iyi inodzora uye inotarisira kuchaja/kuburitsa bhatiri, inoona tembiricha nevoltage yebhatiri, inobatanidza nesystem yemubati, inoenzanisa voltage yebhatiri, uye inotarisira mashandiro ekuchengetedza ebhatiri re lithium.
4) Kutenderera
Maitiro ekuchaja nekuburitsa bhatiri anonzi cycle. Kana bhatiri rikashandisa 80% chete yesimba rayo rese nguva imwe neimwe, hupenyu hwebhatiri re lithium-ion hunogona kusvika zviuru zvenguva.
Rudzi rweBhatiri reLithium
Parizvino, masero e lithium-ion ekutengeserana anonyanya kunge ari cylindrical, sikweya uye akapfava.
Masero e cylindrical e18650 ndiwo masero e lithium-ion ane huwandu hwakanyanya hwekugadzirwa pari zvino. Masero edu emabhatiri eG series monitor ndeerudzi urwu.
Nhevedzano yemasero uye kubatana kwakafanana
Sero ndiro chinhu chikuru chebhatiri re lithiamuHuwandu hwemasero hunosiyana zvichienderana nekushandiswa kwebhatiri, asi mabhatiri ese anofanira kubatanidzwa nenzira dzakasiyana kuti awane voltage nesimba rinodiwa.
Cherechedza: Mamiriro ekubatanidza padanho rakafanana akaoma zvikuru. Saka, kubatana padanho rakafanana kutanga wozobatanidza padanho rakatevedzana zvinogona kuderedza zvinodiwa kuti bhatiri rirambe rakafanana.
Mubvunzo: Ndeupi musiyano uripo pakati pemabhatiri ane ma series matatu nemana akaenzana uye mana akaenzana uye matatu akaenzana?
A: Voltage uye kugona zvakasiyana.Kubatana kwemutsara kunowedzera voltage, uye kubatana kwakafanana kunowedzera simba remagetsi (simba)
1) Kubatana kwakafanana
Ngatitii voltage yebhatiri iri 3.7V uye simba rayo riri 2.4Ah. Mushure mekubatana kwakafanana, simba rekupedzisira resystem rinoramba riri 3.7V, asi simba rayo rinokwira kusvika 7.2Ah.
2) Kubatana kwezvikamu
Ngatitii voltage yebhatiri cell i3.7V uye simba rayo i2.4Ah. Mushure mekubatanidza series, voltage ye terminal yesystem i11.1V, uye simba rayo rinoramba risina kuchinja.
Kana bhatiri riri muzvikamu zvitatu uye zviviri zvakafanana, zvese zviri muzvikamu zvitanhatu zvemaseru 18650, zvinoreva kuti bhatiri iri rine simba re11.1V uye 4.8Ah. Tesla Model-S sedan inoshandisa masero ePanasonic 18650, uye bhatiri re85kWh rinoda masero angangoita zviuru zvinomwe.
Mhedziso
Heltec icharamba ichivandudza ruzivo rwesainzi rwakakurumbira nezvemabhatiri e lithiamuKana muchida, munogona kuiteerera. Panguva imwe chete, tinokupai mapaketi emabhatiri e lithium emhando yepamusoro kuti mutenge uye tinokupai masevhisi akagadzirirwa zvaunoda.
Heltec Energy ndiyo shamwari yako yaunovimba nayo mukugadzira mabheteri. Nekutarisa kwedu kutsvagurudzo nekuvandudza, pamwe chete nemidziyo yedu yakawanda yemabhatiri, tinopa mhinduro dzese kuti tisangane nezvinodiwa zviri kuchinja muindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa vatengi, uye hukama hwakasimba nevatengi zvinoita kuti tive sarudzo yakanaka kune vagadziri vemabheteri nevatengesi pasi rese.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
