DFUN Battery Internal Resistance Measurement Technology: Pɛpɛɛpɛ a Wɔhwɛ so ma Battery Nkwa Nkyɛ

Battery mu ahoɔden a ɛko tia no yɛ ade titiriw a ɛkyerɛ sɛnea battery ahorow no akwahosan ne ne nkwa nna yɛ adwuma. Bere kɔ so no, emu a wɔko tia no kɔ soro nkakrankakra, na ɛka adwumayɛ wɔ ɔkwan a enye so. Eyi betumi ama nsu a wɔde gu mu no ayɛ brɛoo, ahoɔden a wɔhwere no akɔ soro, na ɔhyew a wɔde yɛ adwuma no akɔ soro. Titiriw no, sɛ emu ahoɔden a ɛko tia no boro 25% wɔ bo a ɛfata no mu a, battery ahoɔden so tew kɛse, na ɛma nhyehyɛe no gyina pintinn. Enti, bere ankasa mu ahoɔden a wɔde hwɛ batere no mu ahoɔden so no ho hia.

1. Direct Current (DC) Discharge Ɔkwan a wɔfa so yi

Saa kwan yi hwehwɛ sɛ wɔde anyinam ahoɔden a ɛkɔ soro gyae batere no na wogyina ahoɔden a ɛkɔ fam no so bu emu ahoɔden a ɛko tia no ho akontaa. Bere a ɛma wotumi susuw nneɛma pɛpɛɛpɛ no, ɛma polarization reactions ba battery no mu, na ɛma onyin yɛ ntɛmntɛm. Nea ɛde ba ne sɛ, wɔde saa kwan yi di dwuma titiriw wɔ nhwehwɛmu ne nhwehwɛmu a wɔde yɛ nneɛma a wɔde yɛ nhwehwɛmu no mu na ɛnyɛ nea ɛfata sɛ wɔde hwɛ so bere tenten.

2. Ɔkwan a Wɔfa so Yɛ Mprempren (AC) Impedance a Ɛsesa

Ɛdenam alternating current a ɛwɔ frequency pɔtee bi a wɔde di dwuma na wɔde Ohm Mmara ne capacitance nnyinasosɛm ahorow di dwuma so no, saa kwan yi susuw emu resistance. Nea ɛnte sɛ DC discharge kwan no, AC impedance kwan no kwati sɛ ɛbɛsɛe battery nkwa na ɛde nea efi mu ba a ɛnyɛ nea egyina frequency so kɛse ma. Nsusuwii a wɔyɛ wɔ frequency 1kHz mu no taa yɛ nea ɛyɛ den sen biara. Wɔde saa kwan yi di dwuma kɛse wɔ nnwuma mu na ɛma ɛyɛ pɛpɛɛpɛ kɛse, na mfomso a ɛwɔ mu no yɛ 1% kosi 2%.

DFUN Ano aduru Foforo: AC Low Current Discharge Ɔkwan

DFUN ayɛ nkɔso foforo wɔ atetesɛm AC impedance kwan no so —AC Low Current Discharge Method. Ɛdenam ahoɔden a ɛsesa a ɛnboro 2A a wɔde bedi dwuma na wɔasusuw ahoɔden a ɛsakrasakra pɛpɛɛpɛ so no, wobetumi abu batere no mu ahoɔden a ɛko tia no ho akontaa pɛpɛɛpɛ wɔ bere tiaa bi mu (bɛyɛ sekan biako).

Mfaso Titiriw a Ɛwɔ So:

• Pɛpɛɛpɛ a Ɛkorɔn: Nsusuiɛ a ɛyɛ pɛpɛɛpɛ no bɛn 1%, na ɛkame ayɛ sɛ nea ɛfiri mu ba no ne deɛ ɛfiri nnwuma a ɛtɔ so mmiɛnsa te sɛ Hioki ne Fluke mu no yɛ pɛ.

Ɔsɔretia a Ɛwɔ Mu	2V Batere: 0.1 ~ 50 mΩ	Nneɛma a wotumi yɛ no mpɛn pii: ±(1.0% + 25 μΩ)	Nsusuwii: 0.001 mΩ
	12V Batere: 0.1 ~ 100 mΩ

• Bere Ankasa mu Nhwehwɛmu: Ɛma wotumi nya battery tebea bere ankasa, na esiw adwumayɛ a ɛsɛe a ɛnam emu ahoɔden a ɛkɔ soro so ba no ano yiye.

• Nneɛma a Wɔde Di Dwuma Wɔ Aman pii Mu: Ɛnyɛ sɛ saa mfiridwuma yi yɛ nea wɔde di dwuma wɔ batere a wɔde kɔbere ayɛ mu nko, na mmom etu mpɔn nso wɔ batere ahorow afoforo a ɛko tia emu no so.
