Phakathi nezinyanga eziyisithupha, uzoba nephekhi elilodwa elikhawulela amanye.
Ukungahambisani kweshaja.
Amashaja omthofu{0}e-asidi azolimaza amaphakethe e-lithium. Ijika lokushaja alilungile, i-voltage yokunqamula ayilungile, futhi amashaja athile omthofu{2}}asebenzisa ama-pulses okulinganisa angacupha ukuvalwa kwe-BMS. Sibone izimangalo zewaranti zinqatshelwa ngokuqondile ngoba amakhasimende asebenzise amashaja akhona esikhundleni sokuthenga amayunithi athile e-lithium.
Izinkinga zezintambo.
Amaphekhi e-Lithium angaletha umthamo osheshayo osheshayo kune-asidi-yomthofu. Usayizi wezintambo zangempela zomthofu{2}}amazinga okuphuma kwe-asidi adala ukwehla kwamandla kagesi ngaphansi komthwalo. Uphawu lubukeka njengebhethri elibuthakathaka (ukusheshisa okunensayo, ukulahlekelwa amandla emagqumeni) kodwa ibhethri lilungile. Izintambo ziyisibopho. Lokhu kuvame kakhulu ezinqoleni ezindala lapho ukugqwala kwenyuse ukumelana ne-conductor.
Ukuvalwa kwemodi yokulala.
Amanye amayunithi e-BMS angena kumodi yokulala ngemva kwamahora angu-18-24 ngaphandle komsebenzi. Imisebenzi yesizini egcina amakalishi amaviki phakathi kokusetshenziswa ibuyela emaphaketheni angeke avuke ngaphandle kwenqubo ethile yokusetha kabusha. Hlola ukuziphatha kwe-BMS phakathi nesitoreji esinwetshiwe ngaphambi kokuthenga.
Ukudideka kwemitha ye-SOC.
Lokhu kubonakala kukuncane kuze kube yilapho isivakashi sixhuma ikalishi ngoba imitha ifundeka ku-40% lapho umthamo wangempela wawungu-5%. Amajika kagesi omthofu ahlukile kune-lithium. Igeji iqamba amanga. Faka esikhundleni se-lithium-imitha esilinganisiwe noma izisebenzi zesitimela ukuze zizibe ngokuphelele igeji ekhona.
