U fila bɛɛ bɛ baara kɛ cogoya la hali ni u bɛ tɛmɛ u ka tension nominal hakɛ kan.

"Ne bɛ se ka baara kɛ ni 24V chargeur fɛn o fɛn ye ni n ka 24V batiri ye."Batiri ka kemisɛri nafa ka bon kosɛbɛ. 24V lead-Acid chargeur bɛ bɔ 27,6V lamini na ka ɛrɛzɛnsunw sara-Acid batiriw, nka 24V litiyɔmu batiri bɛ 29,2V de wajibiya charge dafalen na. Baara kɛli ni chargeur suguya jugu ye, o bɛ na ni chargement incomplete ye ani ka se ka dɔgɔya.

"Vervoy (voltage) bɛ tɔgɔlama jukɔrɔ, o la, n ka batiri ka jugu."Voltage (volta) min bɛ voltage nominal (voltage) jukɔrɔ, o bɛ batiri dilen jira cogoya la, a tɛ kɛ ni a tiɲɛnen ye.

Fɔlɔ, aw bɛ voltage yɛrɛyɛrɛ suman ni multimeter qualité ye. Voltage gɛlɛya caman bɛ bɔ sumanikɛlanw na minnu tɛ bɛn ni mɛtɛrɛ sɔngɔ gɛlɛnw ye walima ni sumani kɛra yɔrɔ juguw la circuit kɔnɔ.

Filanan, aw bɛ tension ko suguya dɔn. Low voltage under load bɛ tension jigin kojugu ka bɔ wiring undersized la walima connections man ɲi. Voltage low ni doni tɛ a la, o bɛ kuran gɛlɛyaw walima batiriw bɔlenw jira. Voltage high bɛ se ka regulateur dɛsɛ walima chargeur settings juguw jira.

Sabanan, aw bɛ voltage lajɛ yɔrɔ caman na. Voltage at the battery terminals bɛ se ka kɛ normal ye k’a sɔrɔ voltage min bɛ minɛnw na, o bɛ jigin nafama jira, ka wiring walima connection issues jira components ni ɲɔgɔn cɛ.

Batiriw ka sigida la, aw bɛ tension (voltaji) kɛ ka kɛɲɛ ni charge (sara) ye. Voltage-to-SOC chart ka ɲɛsin i ka batiri kɛrɛnkɛrɛnnen ka chimie ma, o b’a jira ni tension kɔlɔsilenw ye normal ye sisan charge level la. LifePo4 batiriw bɛ tension basigilen mara ka bɔ 90% na ka se 20% ma charge cogo la, o bɛ tension kelen kɛ seko tɔ jiralan ye min tɛ se ka da a kan.

Minɛn minnu tɛna baara kɛ ni sistɛmu ye min bɛ ni tension nominal correcte ye, olu bɛ se ka kɛ ni tension kɛrɛnkɛrɛnnenw ye minnu bɛ kɛ ka bɔ normal range kɔnɔ. Elektroniki sensitif dɔw bɛ tension regulated (±2-3%) de wajibiya hali ni power system bɛ ±10% tolerance di. Ni aw ye voltage regulation fara a kan walima ka baara kɛ ni UPS ye, o bɛ se ka nin ko ninnu ɲɛnabɔ.

Batiri tɔgɔla voltage bɛ baarakɛyɔrɔ cɛmancɛ jira, a tɛ tension maksimali jira. Batiri min bɛ charge dafalen na, o bɛ tɛmɛ a tɔgɔla voltage kan bawo tension nominal bɛ sugandi ka da a cɛmancɛ yɔrɔ kan batiri bɛ a fanga fanba di yɔrɔ min na. A 3.7V litiyɔmu-ion seli bɛ 4,2V kɛ ka bɔ ka taa 3,0V, ni 3.7V bɛ a jira ko a bɛ a ka bɔli waati nafama fanba kɛ yɔrɔ min na.

Ni i ye minɛn dɔ siri walasa k’a tɔgɔla voltage (volta) tɔgɔ fila bɔ, o bɛna a tiɲɛ walima k’a tiɲɛ.

O fɛn caman tigɛli bɛ kɛ mobili ni kurunw kɔnɔ minnu bɛ baara kɛ ni 24V so batiriw ye nka u mago bɛ 12V ɛntɛrinɛti fanga la.

Baara kɛli ni voltage hakɛ dantigɛlen ye, o bɛ minɛnw tiɲɛni bila farati la insulasi tiɲɛni fɛ, a yɔrɔw sumaya kojugu, walima u dɛsɛ teliya la.

Aw bɛ bɔli tension suman ni multimɛtiri ye doni tɛ min na. O bɛ da wulilen ka ciriw ka voltage di i ma, o min bɛna caya dɔɔnin ka tɛmɛ tɔgɔlama kan.
