Tam sim no, tsis muaj kev sib koom ua ke "ultra-fast charging dedicated" cim. Txawm li cas los xij, ntau lub cev ntawv pov thawj yuav qhia txog cov xwm txheej hauv lawv cov ntawv xeem, xws li "them nqi: 5C". Cov neeg yuav khoom yuav tsum tau them sai sai rau qhov ntsuas ntsuas cov lus piav qhia hauv daim ntawv pov thawj. Qee lub tuam txhab tseem yuav hais hauv lawv cov kev qhia tshwj xeeb uas lawv tau dhau "IEC 62619 5C ceev them kev nyab xeeb" ua pov thawj.
Q5: Thaum muaj zog- cov roj teeb hauv lub xeev tau nthuav dav, puas yuav muaj teeb meem kev nyab xeeb ntawm ultra- them ceev ceev yuav daws tau ib zaug thiab rau tag nrho?
Cov khoom siv- lub xeev cov roj teeb, los ntawm tsis muaj cov kua hluav taws xob hluav taws xob hluav taws xob, ua rau txo qis kev pheej hmoo ntawm hluav taws thiab xau thiab pab txo qis lithium dendrite tsim, ua rau muaj kev txhim kho tseem ceeb hauv kev nyab xeeb. Txawm li cas los xij, lawv kuj muaj cov kev ua tsis tiav tshwj xeeb. Piv txwv li, cov khoom siv electrolytes tuaj yeem tsim cov kab nrib pleb vim muaj kev ntxhov siab cuam tshuam thaum lub sij hawm them ceev, ua rau muaj kev tiv thaiv sab hauv lossis luv luv. Yog li ntawd, thaum lub hom phiaj ntawm kev tswj hwm kev nyab xeeb yuav hloov tom qab siv dav, nws yuav tsis ploj; BMS thiab kev tiv thaiv kab ke yuav nyob twj ywm qhov tseem ceeb.
