Etape 1: Current constant (CC) – Charge teliya fasa
Kuran basigilen waati la, chargeur bɛ kuran sabatilen di, min latigɛra ka kɔn.
• A jogo : Voltage bɛ wuli ka taa a fɛ ka sɔrɔ kuran bɛ to a cogo la.
• Se sɔrɔli : Li-ion batiri bɛ se ka se 60% fo 80% ma a seko bɛɛ lajɛlen na nin waati in na.
• C-Rate : A ka c’a la, chargement current ɲuman bɛ 0,2C ni 1,0C cɛ. Ni 2000mAh seli ye, 0,5C hakɛ bɛ kɛ 1000mA ye.
• Tɛmɛsira : CC fasa bɛ taa ɲɛ fo selilabana ka se a dan na, a ka c’a la, a bɛ 4,2V lamini seli kelen na.
Taabolo 2nan : Voltage constant (CV) – Topping-Off min bɛ mɔgɔ tanga
Ni 4,2V dakun sera, chargeur bɛ wuli ka taa constant voltage mode la cogo la min tɛ fɛn tiɲɛ.
• A jogo : Chargeur bɛ voltage minɛ ka jɔ ka sɔrɔ current bɛ ka dɔgɔya dɔɔni dɔɔni.
• Mun na a ka kan : Ni nin CV taabolo in tun tɛ, kuran tun bɛna taa a fɛ ka ionw gɛn ka don, ka kɛ sababu ye ka nɛgɛ litiyamu bila anode kan, o min ye funteni boli sababu fɔlɔ ye.
• Dabila : Litiyamu-ion charge cycle bɛ dafa, walima a bɛ ban, ni chargement current jiginna ka se 'end-of-charge' hakɛ dɔgɔman ma, a ka c’a la 0,02C ni 0,07C cɛ.
Fɛɛrɛ ɲumanw ni BMS kɔlɔsili
Sarali ɲɛnabɔli tɛ kɛ yɔrɔ la min tɛ fɛn ye. Ka ɲɛsin diɲɛ kɔnɔ baarakɛminɛnw ma i n’a fɔ kunnafonidilanw walima telefɔni basigiyɔrɔw, a barikama
