Amabhethri e-lithium asephenduke ingxenye ebalulekile ye-ecosystem entsha yamandla, enika amandla yonke into kusukela ezimotweni zikagesi nezindawo zokugcina amandla kuya kuma-electronics aphathwayo. Nokho, inselele evamile abasebenzisi emhlabeni wonke ababhekana nayo umthelela obalulekile wezinga lokushisa ekusebenzeni kwebhethri—ihlobo livame ukuletha izinkinga ezifana nokuvuvuka kwebhethri nokuvuza, kuyilapho ubusika buholela ebangeni elinciphe kakhulu kanye nokusebenza kabi kokushaja. Lokhu kusekelwe ekuzweleni kwezinga lokushisa okungokwemvelo kwamabhethri e-lithium, namabhethri e-lithium iron phosphate, okungenye yezinhlobo ezisetshenziswa kakhulu, asebenza kahle kakhulu phakathi kuka-0°C no-40°C. Ngaphakathi kwalobu bubanzi, ukusabela kwamakhemikhali kwangaphakathi nokufuduka kwe-ion kusebenza ngokusebenza kahle kakhulu, kuqinisekisa ukukhishwa kwamandla okuphezulu.
Amazinga okushisa angaphandle kwaleli windi eliphephile adala ubungozi obukhulu kumabhethri e-lithium. Ezindaweni ezishisa kakhulu, i-electrolyte volatilization kanye nokubola kuyashesha, kwehlisa ukuqhutshwa kwe-ion kanye namandla okukhiqiza igesi ebangela ukuvuvukala noma ukuphuka kwebhethri. Ukwengeza, ukuqina kwesakhiwo sezinto ze-electrode kuyawohloka, okuholela ekulahlekelweni kwamandla okungenakulungiseka. Okubaluleke nakakhulu, ukushisa okweqile kungabangela ukubaleka okushisayo, ukusabela kweketango okungase kubangele izehlakalo zokuphepha, okuyimbangela enkulu yokungasebenzi kahle kwemishini emisha yamandla. Amazinga okushisa aphansi ayinkinga ngokulinganayo: ukwanda kwe-electrolyte viscosity kunciphisa ukufuduka kwe-lithium ion, kuphakamisa ukumelana kwangaphakathi nokunciphisa ukusebenza kahle kokushaja. Ukushaja okuphoqiwe ezimeni ezibandayo kungabangela ama-ion e-lithium ukuthi agibele endaweni ye-electrode engalungile, kwakhe i-lithium dendrites ebhoboza isihlukanisi futhi icuphe amasekhethi amafushane angaphakathi, okudale izingozi ezinkulu zokuphepha.
Ukuze unciphise lezi zingozi ezibangelwa izinga lokushisa, i-Lithium Battery Protection Board, ngokuvamile eyaziwa ngokuthi i-BMS (Isistimu Yokulawula Ibhethri), ibalulekile. Imikhiqizo ye-BMS yekhwalithi ephezulu ifakwe izinzwa zokushisa ze-NTC ezinembayo ezihlala ziqapha izinga lokushisa lebhethri. Uma amazinga okushisa edlula imikhawulo ephephile, isistimu icupha i-alamu; ezimweni zama-spikes okushisa asheshayo, ngokushesha kusebenze izinyathelo zokuvikela ukusika isifunda, ukuvimbela umonakalo owengeziwe. I-BMS ethuthukisiwe enomqondo wokulawula izinga lokushisa eliphansi lokushisa ingaphinda idale izimo zokusebenza ezilungile zamabhethri ezindaweni ezibandayo, ibhekane ngokuphumelelayo nezinkinga ezifana nebanga elincishisiwe nobunzima bokushaja, iqinisekisa ukusebenza okuzinzile kuzo zonke izimo ezihlukene zokushisa.
Njengengxenye eyinhloko yohlelo lokuphepha kwebhethri le-lithium, i-BMS esebenza kahle kakhulu ayigcini nje ngokuvikela ukuphepha kokusebenza kodwa futhi yelula ubude bebhethri, inikeze ukusekelwa okubalulekile kokusebenza okuthembekile kwemishini emisha yamandla.
