Batere a wɔde kɔbere ayɛ no ayɛ tweatibo wɔ mfiridwuma a wɔde siesie ahoɔden mu fi bere a wɔyɛɛ no wɔ afeha a ɛto so 19 mfinimfini no. Wɔde saa tumi a wotumi de ho to so yi di dwuma kɛse wɔ nneɛma ahorow mu. Sɛnea lead-acid battery yɛ adwuma no ho ntease ho hia na ama wɔn adwumayɛ ayɛ papa na wɔatrɛw wɔn nkwa nna mu.
Battery a ɛwɔ lead-acid no yɛ nneɛma atitiriw pii a ɛbom yɛ adwuma de sie anyinam ahoɔden na ɛma ɛyɛ adwuma yiye. Nneɛma titiriw no bi ne:
Mprɛte: Wɔde kɔbere dioxide (prɛte a ɛyɛ papa) ne sponge lead (mprɛte a enye) na ɛyɛe, na wɔde eyinom gu electrolyte solution mu.
Electrolyte: sulfuric acid ne nsu a wɔde afra, a ɛma nnuru a ɛho hia ma ahoɔden a wɔkora so no yɛ mmerɛw.
Nneɛma a wɔde yiyi mu: Wɔde nneɛma a ɛyɛ tratraa a ɛma nsu ntumi nkɔ mu no si mprɛte a ɛyɛ papa ne nea enye no ntam na amma wɔantumi ankyɛ bere a ɛma ionic no kɔ so no.
Ade a wɔde gu mu: Akataso a ɛyɛ den a ɛwɔ mu nneɛma nyinaa, a mpɛn pii no wɔde plastic anaa rɔba a ɛyɛ den na ɛyɛ.
Terminals: Battery no wɔ terminal abien: positive ne negative. Terminals a wɔatoto mu no boa ma current discharge a ɛkorɔn ne service nkwa tenten.
Batere a ɛwɔ kɔbere mfrafrae a ɛyɛ adwuma no di dwuma wɔ nnuru a ɛyɛ adwuma a ɛdannan no ho wɔ nneɛma a ɛyɛ adwuma no ntam wɔ mprɛte no so ne electrolyte solution no so.
Bere a wɔreyi nsu no, adeyɛ a edidi so yi ba:
Sulfuric acid a ɛwɔ electrolyte no mu no ne mprɛte a ɛyɛ papa (a ɛwɔ anim) ne nea enye (sponge lead) nyinaa yɛ adwuma. Saa adeyɛ yi ma lead sulfate ba mprɛte abien no nyinaa so bere a ɛreyi ɛlɛtrɔnik ahoɔden afa abɔnten kwan bi so, na ɛma anyinam ahoɔden. Bere a ɛlɛtrɔnik fi mprɛte a enye no mu kɔ mprɛte a ɛyɛ papa no so denam abɔnten so adesoa so no, wɔde ahoɔden ma mfiri a ɛka ho no.
Bere a wɔrebɔ ka no, wɔdane saa adeyɛ yi:
Abɔnten tumi fibea de voltage di dwuma wɔ battery terminals no so. Voltage a wɔde di dwuma no ma ɛlɛtrɔnik san kɔ mprɛte a ɛnyɛ papa no mu bere a ɛdan kɔbere sulfate no san kɔ ne mfitiase tebea horow mu—adi dioxide a ɛwɔ mprɛte a ɛyɛ papa ne kɔbere a ɛwɔ mprɛte a enye so no so. Sulfuric acid dodow kɔ soro bere a nsu mu nneɛma nketenkete no mu paapae bere a wɔde anyinam ahoɔden yɛ adwuma no.
Saa cyclical su yi ma kwan ma wɔsan de lead-acid battery no gu mu mpɛn pii a wɔnsɛe no kɛse bere a wɔhwɛ so yiye no.
Nneɛma a wɔde bɔ charge a ɛfata .
Nneyɛe a etu mpɔn a wɔde bɔ ka no ho hia kɛse na ama wɔatumi akura adwumayɛ a eye sen biara mu wɔ batere a wɔde kɔbere ayɛ mu:
Constant voltage charging: Saa kwan yi ma kwan ma charge wɔ baabi a wɔhwɛ voltage no so wɔ daa bo mu. Mfaso a ɛwɔ so ne sɛ, wɔyɛ charge current no ho adwuma ankasa bere a battery no charge state no sesa no.
Nneɛma a ɛwɔ afã abiɛsa a wɔde bɔ ka: a ɛwɔ ahoɔden a wɔde bɔ nneɛma pii (ɛreyɛ daa), absorption charge (a ɛkɔ so daa), ne float charge (maintenance mode), saa ɔkwan yi hwɛ hu sɛ ɛbɛsan ayɛ adwuma yiye a adwennwen a ɛboro so wɔ batere no afã horow so.
Ɔhyew a wɔhwɛ so bere a wɔrebɔ ka no ho hia; Ɔhyew a ɛkɔ soro no betumi ama nneɛma a ɛsɛe ade te sɛ gassing anaa thermal runaway ayɛ ntɛmntɛm.
Akwan a etu mpɔn a wɔfa so yi nsu fi mu .
Ɛsɛ sɛ wɔhwɛ nsu a efi mu ba no kyinhyia so yiye na ama wɔakwati nsu a emu dɔ a ebetumi apira batere akwahosan:
Kwati sɛ wobɛtwe akɔ akyiri asen 50% depth-of-discharge bere biara a ɛbɛyɛ yiye; Nsu a ɛtaa fi mu kɔ akyiri no ma nkwa nna nyinaa yɛ tiaa kɛse.
Lead-acid batere ho hia ma ahoɔden a wotumi de ho to so a wɔkora so wɔ nneɛma ahorow mu. Ɛdenam wɔn nhyehyɛe ne adwumayɛ nnyinasosɛm ahorow a wɔbɛte ase so no, wɔn a wɔde di dwuma no betumi ama adwumayɛ ayɛ papa na wɔatrɛw wɔn nkwa nna mu. Charging ne discharge monitoring a ɛfata ho hia kɛse. a wɔde bedi dwuma . DFUN Battery Monitoring Systems (BMS) hwɛ hu sɛ battery a wɔde kɔbere ayɛ no da so ara yɛ ahoɔden a wɔkora so ano aduru no fã titiriw. System no hwɛ ankorankoro cell voltages, na charge/discharge currents wɔ multi-cell configurations mu, na ɛka battery activation ne battery a ɛkari pɛ ho na ama control ne maintenance ayɛ yiye.
