Battery mu a wɔko tia no yɛ ade titiriw a ɛkyerɛ sɛnea batere no akwahosan ne ne dwumadi te. Bere kɔ so no, emu ahoɔden a ɛko tia nyarewa no kɔ soro nkakrankakra, na ɛka adwumayɛ wɔ ɔkwan a enye so. Eyi betumi ama nsu a ɛkɔ fam no ayɛ brɛoo, ahoɔden a ɛkɔ soro, ne ɔhyew a ɛkɔ soro wɔ adwumayɛ mu. Titiriw no, sɛ emu ahoɔden boro 25% wɔ bo a ɛyɛ daa no mu a, batere tumi so tew kɛse, na ɛma nhyehyɛe no gyina pintinn. Enti, bere ankasa mu tumi a wɔde hwɛ batere no mu ahoɔden so no ho hia.
1. Direct current (DC) kwan a wɔfa so yi nsu fi mu .
Saa kwan yi fa battery no a wɔde current a ɛkorɔn gu mu na wɔde bu emu resistance a egyina voltage drop so. Bere a ɛma susudua no yɛ pɛpɛɛpɛ kɛse no, ɛma polarization reactions ba batere no mu, na ɛma onyin yɛ ntɛmntɛm. Ne saa nti, wɔde saa kwan yi di dwuma titiriw wɔ nhwehwɛmu ne nhwehwɛmu a wɔyɛ mu na ɛnyɛ nea ɛfata sɛ wɔde hwɛ bere tenten.
2. Alternating current (AC) impedance kwan .
Ɛdenam current a ɛsesa a ɛyɛ frequency pɔtee bi a wɔde di dwuma na wɔde Ohm mmara ne capacitance nnyinasosɛm ahorow di dwuma so no, saa kwan yi susuw emu ɔsɔretia ho. Nea ɛnte sɛ DC discharge kwan no, AC impedance kwan no kwati battery nkwa a ɛsɛe ade na ɛde nea efi mu ba a ɛnyɛ frequency-efɛ. Nsusuwii a wɔyɛ wɔ frequency a ɛyɛ 1kHz no taa yɛ nea ɛyɛ den sen biara. Wɔde saa kwan yi di dwuma kɛse wɔ nnwuma mu na ɛma wonya pɛpɛɛpɛyɛ a ɛkorɔn, a mfomso a ɛwɔ mu no yɛ 1% ne 2% ntam.
DFUN anya nkɔso foforo wɔ atetesɛm AC impedance kwan no so —AC low current discharge kwan no. Ɛdenam current a ɛsesa a ɛnyɛ nea ɛboro 2A a wɔde bedi dwuma na wɔasusuw voltage nsakrae 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:
Pɛpɛɛpɛyɛ a ɛkorɔn: Nsusuwii a ɛyɛ pɛpɛɛpɛ no bɛn 1%, na ɛkame ayɛ sɛ nea efi mu ba no ne nea ɛwɔ nnipa a wɔto so abiɛsa te sɛ Hioki ne Fluke de no yɛ pɛ.
mu a ɛko tia . | 2V Battery: 0.1 ~ 50 MΩ . | Nneɛma a wotumi yɛ no mpɛn pii: ±(1.0% + 25 μΩ) . | Nsusuwii: 0.001 MΩ . |
12V Battery: 0.1 ~ 100 MΩ . |
Nkɛntɛnso biara nni batere akwahosan so: Esiane sɛ current a ɛba fam ne nea ɛba fam koraa no amplitude nti, saa kwan yi mpira battery no anaasɛ ɛma onyin yɛ ntɛmntɛm.
Real-time Monitoring: Ɛma wotumi nya battery tebea bere ankasa mu, na ɛma adwumayɛ sɛe a ɛnam mu sɔre tia a ɛkɔ soro no siw ano wɔ ɔkwan a etu mpɔn so.
Nneɛma a wɔde di dwuma wɔ akwan horow so: Ɛnyɛ sɛ saa mfiridwuma yi yɛ nea wɔde di dwuma wɔ batere a wɔde kɔbere ayɛ mu nko, na mmom etu mpɔn nso ma wɔde hwɛ sɛnea wɔde wɔn ho hyɛ mu wɔ batere ahorow afoforo mu.
Hwɛ sɛ wo batere no bɛkɔ so ayɛ nea eye sen biara, na ama wo tumi nhyehyɛe ahorow no agyina na wotumi de ho to so.
