Kune mota yemagetsi chaiyo

Mabhatiri emagetsi ndiwo anodhura zvakanyanya

Chinhu chikuru chinokanganisa hupenyu hwebhatiri

Uye chirevo chekuti "kuchaja nekukurumidza" chinokuvadza bhatiri

Zvinobvumirawo varidzi vemotokari dzemagetsi vakawanda kuti

zvakamutsa kusava nechokwadi

Saka chokwadi chii?

01
Kunzwisisa kwakarurama maitiro e "kuchaja nekukurumidza"

Tisati tapindura mubvunzo uyu, tingangofanira kuziva maitiro e "kuchaja nekukurumidza". Kubva pakuisa pfuti kusvika pakuchaja, matanho maviri anoita seari nyore anovanza matanho anodiwa shure kwayo:

Kana musoro wepfuti yekuchaja wakabatana nemugumo wemotokari, murwi wekuchaja uchapa simba reDC rinobatsira rine voltage shoma kumugumo wemotokari kuti rishandise BMS yakavakirwa mukati (battery management system) yemotokari yemagetsi. Mushure mekushanda, murwi wemotokari nemurwi wemoto zvinoita "kubata maoko" kuti vachinje maparamita ekutanga ekuchaja akadai sesimba guru rekuchaja rinodiwa nemugumo wemotokari uye simba guru rekubuda kwemurwi wemoto.

Mushure mekunge mativi maviri aya aenderana nemazvo, BMS (system yekugadzirisa bhatiri) iri pamucheto wemotokari ichatumira ruzivo rwekuda kwesimba remagetsi kumurwi wekuchaja, uye murwi wekuchaja uchagadzirisa voltage yayo yekubuda uye current zvichienderana neruzivo, uye wotanga kuchaja mota zviri pamutemo.

"Kuchaja nekukurumidza" hakuzokuvadzi bhatiri

Hazvina kuoma kuona kuti maitiro ese e "kuchaja nekukurumidza" kwemotokari dzemagetsi inzira yekuti magumo emotokari nemagumo emurwi zvinoenderana, uye pakupedzisira magumo emurwi anopa simba rekuchaja zvinoenderana nezvinodiwa nemagumo emotokari. Izvi zvakafanana nemunhu ane nyota uye anoda kunwa mvura. Kuti mvura yakawanda sei yekunwa uye kumhanya kwemvura yekunwa zvinoenderana zvakanyanya nezvinodiwa nemunwi iye pachake. Ehe, murwi wekuchaja weStar Charging pachawo une mabasa akawanda ekudzivirira kuchengetedza mashandiro ebhatiri. Saka, kazhinji, "kuchaja nekukurumidza" hakuzokuvadzi bhatiri.

Munyika yangu, kunewo chinodiwa chehuwandu hwemaseti emagetsi emabhatiri, ayo anofanira kunge anopfuura chiuru. Semuenzaniso, tichitarisa mota yemagetsi ine makiromita mazana mashanu, zvichibva pamatanho ekuchaja nekuburitsa magetsi chiuru, zvinoreva kuti mota inogona kumhanya makiromita mazana mashanu. Kazhinji, mota yega inongosvika makiromita mazana maviri ezviuru muhupenyu hwayo. -300,000 makiromita ekutyaira. Kana uchiona izvi, iwe uri pamberi pechidzitiro ucharamba uchinetseka ne "fast charging"

Kuchaja kushoma uye kuburitsa mvura kushoma, zvichibatanidza kuchaja nekukurumidza uye kunonoka

Ehe, kune vashandisi vane mamiriro ekuisa mapombi ekuchaja kumba, "kuchaja zvishoma nezvishoma" kumba isarudzo yakanakawo. Uyezve, kana paine chiratidziro chimwe chete pa100%, hupenyu hwebhatiri hwe "kuchaja zvishoma nezvishoma" huchareba ne15% kupfuura hwe "kuchaja nekukurumidza". Izvi zvinokonzerwa nekuti kana mota "ichichaja nekukurumidza", magetsi emagetsi akawandisa, tembiricha yebhatiri inokwira, uye maitiro emakemikari ebhatiri haana kukwana, zvichikonzera fungidziro yekuchaja zvizere, iyo inonzi "simba remagetsi". Uye "kuchaja zvishoma nezvishoma" nekuti magetsi emagetsi madiki, bhatiri rine nguva yakakwana yekupindura, uye kukanganiswa kwaro kudiki.

Saka, mukuita kwekuchaja kwezuva nezuva, unogona kusarudza nzira yekuchaja zvinoenderana nemamiriro chaiwo, uye kutevedzera musimboti wekuti "kuchaja kushoma uye kuburitsa kushoma, kusanganiswa kwekuchaja nekukurumidza uye kunonoka". Kana iri bhatiri re lithium ternary, zvinokurudzirwa kuchengetedza SOC yemotokari iri pakati pe20%-90%, uye hazvidikanwi kuti utsvage 100% yakazara nguva dzese. Kana iri bhatiri re lithium iron phosphate, zvinokurudzirwa kurichaja kanenge kamwe chete pasvondo kuitira kugadzirisa kukosha kweSOC yemotokari.
