Yemotokari yemagetsi yakachena

Mabhatiri emagetsi anodhura zvakanyanya

Ichowo chinhu chakakosha chinokanganisa hupenyu hwebhatiri

Uye shoko rokuti "kukurumidza kuchaja" rinokuvadza bhatiri

Inobvumirawo varidzi vakawanda vemotokari yemagetsi kuti

kwakamutsa kusava nechokwadi

Saka chokwadi ndechipi?

01
Kunzwisisa kwakarurama kwe "kukurumidza kuchaja" maitiro

Tisati tapindura mubvunzo uyu, tinogonawo kuziva maitiro e "kukurumidza kuchaja".Kubva pakuisa pfuti kusvika pakuchaja, nhanho mbiri dzinoita sedzakareruka dzinovanza nhevedzano yematanho anodiwa kumashure kwayo:

Kana iyo yekuchaja musoro wepfuti yakabatana kumagumo emotokari, murwi wekuchaja unopa yakaderera-voltage yekubatsira DC simba kumagumo emotokari kuti iite yakavakirwa-mukati BMS (bhatiri manejimendi system) yemotokari yemagetsi.Mushure mekuita activation, iyo mota inopera uye iyo murwi inopera inoita "kukwazisana" kuchinjisa ekutanga yekuchaja paramita senge yakakwira yekuchaja simba rinodiwa nekuguma kwemotokari uye yakanyanya kubuda simba remurwi kupera.

Mushure mekunge mapato maviri aya afananidzwa nemazvo, iyo BMS (bhatiri manejimendi system) kumagumo emotokari inotumira ruzivo rwekuda kwesimba kumurwi wekuchaja, uye murwi wekuchaja uchagadzirisa kubuda kwayo magetsi uye ikozvino maererano neruzivo, uye kutanga kubhadharisa zviri pamutemo. motokari.

"Kukurumidza kuchaja" hakuzokanganisa bhatiri

Hazvina kuoma kuwana kuti iyo nzira yese ye "kukurumidza kuchaja" yemotokari dzemagetsi inzira iyo iyo mota inopera uye kuguma kwemurwi kunoita parameter inoenderana nemumwe, uye pakupedzisira murwi wekupedzisira unopa simba rekuchaja zvinoenderana nezvinodiwa. yekuguma kwemotokari.Izvi zvakafanana nemunhu ane nyota uye anoda kunwa mvura.Imvura yakawanda sei yekunwa uye kumhanya kwemvura yekunwa zvinoenderana zvakanyanya nezvinodiwa nemunwi wacho pachake.Ehe, iyo Nyeredzi yekuchaja murwi pachayo zvakare ine akawanda ekudzivirira mabasa ekudzivirira kuita kwebhatiri.Naizvozvo, kazhinji kutaura, "kukurumidza kuchaja" hakuzokuvadza bhatiri.

Munyika yangu, pane zvakare chinosungirwa chinodiwa kune huwandu hwematenderedzwa emagetsi mabhatiri maseru, ayo anofanirwa kunge anopfuura 1,000 nguva.Kutora motokari yemagetsi ine rwendo rwekufamba rwemakiromita mazana mashanu semuenzaniso, zvichibva pa1,000 yekuchaja uye yekuburitsa matenderera, zvinoreva kuti mota inogona kumhanya 500,000 makiromita.Kazhinji, mota yakazvimirira inongosvika 200,000 makiromita muhupenyu hwayo.-300,000 makiromita ekutyaira.Uchiona izvi, iwe pamberi pechidzitiro ucharamba uchinetseka ne "kukurumidza kuchaja"

Kuchaja kwakadzika uye kuburitsa kwakadzika, kusanganisa nekukurumidza uye kunononoka kuchaja

Ehe, kune vashandisi vane mamiriro ekuisa mirwi yekuchaja imba, "inononoka kuchaja" kumba zvakare isarudzo yakanaka.Uyezve, munyaya yekuratidzwa kwakafanana pa100%, hupenyu hwebheteri ye "slow charge" huchava hurefu hwe15% kupfuura iyo ye "kukurumidza kuchaja".Izvi zvinonyanya kukonzerwa nekuti kana mota "ichaja nekukurumidza", ikozvino yakakura, kutonhora kwebhatiri kunokwira, uye bhatiri kemikari yekuita haina kukwana, zvichikonzera kunyengedza kwechaji yakazara, iyo inonzi inonzi. "virtual power".Uye "kunonoka kuchaja" nekuti ikozvino idiki, bhatiri rine nguva yakakwana yekupindura, uye kukanganisa kwacho kudiki.

Naizvozvo, muchirongwa chekuchaja chezuva nezuva, unogona kuchinjika kusarudza nzira yekuchaja zvinoenderana nemamiriro chaiwo, uye wotevera musimboti we "kushaja kwakadzika uye kuburitsa kudzika, musanganiswa wekukurumidza uye unononoka kuchaja".Kana iri ternary lithium bhatiri, zvinokurudzirwa kuchengetedza iyo SOC yemotokari pakati pe20% -90%, uye hazvifanirwe kutsvaga nemaune 100% yakazara charge nguva dzese.Kana iri lithium iron phosphate bhatiri, inokurudzirwa kuichaja kanenge kamwe pasvondo kuitira kugadzirisa mota SOC kukosha.
