Ɔkwan bɛn so na wokari pɛ wɔ lead-acid battery mu?

Bokiti no nkɛntɛnso: Nsu dodow a bokiti betumi akura no gyina ne gyinabea a ɛyɛ tiaa sen biara no so.

Wɔ batere ahemman mu no, wohu bokiti nkɛntɛnso: batere a wɔde ahyɛ mu no adwumayɛ gyina nkwammoaa a ɛwɔ ahoɔden a ɛba fam koraa no so. Sɛ voltage balancing no nyɛ papa a, adeyɛ no ba sɛ battery no ayɛ ma koraa wɔ charging bere tiaa bi akyi.

Ɔkwan bɛn so na wobedi battery voltage a ɛkari pɛ ho asɛm no ho dwuma na wɔatrɛw wɔn nkwa nna mu?

Atetesɛm mu ɔkwan a wɔfa so yɛ: 

Manual periodic inspection de kyerɛ batere a ahoɔden a ɛwɔ mu no sua na ankorankoro de ahoɔden a ɛba fam na ɛbɔ batere no so.

Ɔkwan a ɛyɛ nyansa: . 

BMS (battery management system) no wɔ automatic balancing function a ɛtumi kari pɛ wɔ voltage mu bere a wɔrebɔ charging ne discharging no.

Automatic balancing no bi ne active ne passive balancing.

Nea ɛka kari a wɔkari pɛ ho ne charging-based ne energy-transfer-based balancing.

Active balancing (ahoɔden a wɔde fa nneɛma so):

Wɔnam ahoɔden a wɔde kɔ baabi foforo a ɛyera so na ɛyɛ kari pɛ, kyerɛ sɛ, ahoɔden a efi nkwammoaa a ɛwɔ ahoɔden a ɛkorɔn mu kɔ wɔn a wɔn ahoɔden sua no mu, na wonya ahoɔden a ɛkari pɛ wɔ ahoɔden nyinaa mu a ahoɔden a ɛyera kakraa bi na ɛwɔ mu; Enti, wɔsan frɛ no adehwere a ɛkari pɛ.

 

Mfaso:  Ahoɔden a ɛyera kakraa bi, ahoɔden a ɛkɔ soro, bere tenten, mprempren a ɛkorɔn, nkɛntɛnso a ɛba ntɛmntɛm.

Mfomso:  amansin a ɛyɛ den, ɛho ka yɛ den.

Active balancing (a egyina charge so):

DC/DC tumi module bi wɔ monitoring cell sensor biara mu. Wɔ float charging mu no, module no charge cell no ne voltage a ɛba fam koraa no ma ne charge kɔ soro kosi sɛ ebedu set voltage balance no ho.

 

Mfaso a ɛwɔ so:  Wɔde wɔn ani asi so sɛ wɔbɛma nkwammoaa a wontua hwee anaasɛ wɔanyɛ adwuma yiye.

Mfomso:  Ɛka a ɛkɔ soro esiane hia a ehia sɛ wɔyɛ DC/DC tumi module ahorow nti, asiane a ɛwɔ hɔ sɛ wɔbɛbɔ ka a ɛboro so (ebetumi aba sɛ wobebu atɛn wɔ ɔkwan a ɛnteɛ so), ɛka kɛse a wɔbɔ wɔ nsiesie ho esiane mmeae a ebetumi adi huammɔ nti.

Passive balancing (a egyina discharging so):

Passive balancing taa yɛ nea ɛfa nkwammoaa a ɛwɔ ahoɔden a ɛkorɔn a wɔde fa resistors mu, a ɛma ahoɔden a ɛyɛ ɔhyew no fi hɔ ma ɛyɛ nea ɛyɛ den sɛ wobenya ahoɔden a ɛkari pɛ, na ɛnam so ama nkwammoaa afoforo a wɔde charge no ayɛ kɛse wɔ bere a wɔde charge no mu.

 

Mfaso a ɛwɔ so:  low discharge current, mfiridwuma a wotumi de ho to so, ɛho ka sua.

Mfomso:  Bere tiaa a wɔde yi nsu fi mu, nkɛntɛnso a ɛba brɛoo.

Sɛ yɛbɛbɔ no mua a, mprempren BMS a wɔde yɛ lead-acid batere no mu dodow no ara gye passive balancing tom. Daakye, DFUN de hybrid balancing bɛba, a ɛma nkwammoaa a ɛwɔ ahoɔden kɛse no kari pɛ denam nkwammoaa a ɛma nsu fi mu ne nea ɛwɔ ahoɔden a ɛba fam so denam charge so.
