Yu nɔ go ebul fɔ jɔj batri bay wan nɔmba. Di mistek we kɔmɔn pas ɔl na fɔ biliv se ay vɔlɔt min wɛlbɔdi bateri — bateri we sidɔm na di shelf fɔ siks mɔnt wit ebi sɛlf-dischaj kin stil sho nia-ful opin-sɔrkwit vɔlɔt we in yuzabl kapasiti dɔn dɔŋ bay af. Di kɔmɔn we, wan ol bateri we gɛt bɔku bɔku saykl dɛn kin sho akseptabl vɔlɔt bɔt i kin sag dɔŋ di kɔt ɔf ɔnda lod. dis tu egzampl dεm de sho se singl-paramita jכjmεnt inevitably de lid to misdiagnosis: kapasiti, vכltεj, εn intanεt rεsistεns כl fכ evaluate tכgeda.
Kapasiti de tɛl yu aw bɔku ɛnaji di bateri kin stil kip, we dɛn kin ɛksprɛs insay ampere-awa (Ah) — di tɔtal chaj we dɛn kin gi ɔnda standad dischaj kɔndishɔn. Kapasiti fade na di mɔs dairekt indikɛtɔ fɔ di bateri ol. Batri we dɛn rayt 100Ah we kin jɔs gi 70Ah afta tri ia gɛt stet ɔf wɛlbɔdi (SOH) we na 70%. Kapasiti tɛst nid fɔ ful dischaj to di kɔt ɔf vɔlɔt, we kin tek bɔku tɛm — tipikli nɔ fayn fɔ kwik ɛvride chɛk, bɔt i impɔtant fɔ akseptans tɛst, ɛni ia mentenɛns sɔvɛ, ɛn fɔ disayd fɔ di ɛnd-ɔf-layf.
Intanɛt rɛsistɛns de sho di impedans insay di bateri, we dɛn mɛzhɔ insay miliɔm (mΩ). I gɛt tri kɔmpɔnɛnt dɛn: polarizeshɔn rɛsistɛns (frɔm ilɛktrɔkɛmik riakshɔn kaynɛtiks), ɔmik rɛsistɛns (frɔm ilɛktrɔd matirial rɛsistiviti ɛn kɔntakt intafɛs), ɛn ilɛktrɔlayt rɛsistɛns. Nyu batri dɛn kin sho intanɛnt rɛsistɛns insay di tɛn miliɔm ɔ smɔl pas dat. as di saykl kכnt de inkrεs εn εlektrolayt de dכn, di intanεt rεsistεns de go כp sכmtεm. di krichכl insayt na dat intanεt rεsistεns εn kapasiti fεd nכ de lεnya — rεsistεns de chenj bכku bכku wan insay di fכs haf fכ layf, dεn de aksεlεrayt insay di lεta haf. Bay di tɛm we wi kin si se di kapasiti dɔn go dɔŋ, di rɛsistɛns kin dɔn ɔlrɛdi dɛbul ɔ mɔ. Dis kin mek di intanɛnt rɛsistɛns fayn fɔ wɔn pɔsin kwik kwik wan pas fɔ jɔj am fayn fayn wan.
Vɔltɛm na di paramita we izi fɔ ɔndastand bɔt i kin izi fɔ rid am di rayt we. Open-circuit voltage (OCV) de sho ɔl di stet ɔf chaj (SOC) — aw bɔku ɛnaji de lɛf — nɔto aw bɔku di bateri kin rili gi. Wan 12V lid-asid bateri we de na 12.6V, ful-ɔp wit chaj; na 12.0V i de lɛk 75% SOC; na 11.4V lɛk 25% SOC; na 10.5V i dɔn nia fɔ dɔn. Bɔt SOC ɛn SOH nɔto di sem tin — bateri we gɛt ay SOC wit ay intanɛnt rɛsistɛns go sag dɔŋ ɔpreshɔn vɔlɔt di mɔnt we dɛn aplay lod, ɛn di ikwipmɛnt go shɔt ilɛksɛf. Vɔltɛm fɔ ɔltɛm intaprit togɛda wit lod, tru lod tɛst ɔ kapasiti tɛst, nɔ ɛva tru opin-sɔrkwit vɔlɔt nɔmɔ.
Difrɛn aplikeshɔn dɛn kin aks fɔ difrɛn we dɛn fɔ tɛst, ɛn fɔ pik di rɔng we, i kin west tɛm ɛn i kin mis rial prɔblɛm dɛn. Kapasiti tɛst (ful dischaj) na di gold standad fɔ no di bateri wɛlbɔdi, bɔt i gɛt tu tin dɛn we yu fɔ du bifo tɛm: i nid fɔ ful dischaj di bateri, we min se yu fɔ tek wan onlayn sistɛm ɔflayna; ɛn i kin tek lɔng tɛm — 100Ah bateri we dɛn dischaj na 5A nid 20 awa. Kapasiti tɛst fit fɔ: nyu bateri akseptɛns, ɛni ia mentenɛns sɔv, ɛnd-ɔf-layf ditarminieshɔn bifo batri riplesmɛnt, ɛn dip ɛvalueshɔn we dɛn de du fɔlt analisis.
Intanɛt rɛsistɛns tɛst na fast, nɔ de pwɛl, ɛn i kin bi na di intanɛt. Fɔ mɛzhɔ de tek sɛkɔn sɛkɔn nɔmɔ, dɛn nɔ nid fɔ pul di bateri frɔm di savis, ɛn dɛn nɔ nid fɔ dischaj lod. Dis mek i fayn fɔ inspekshɔn dɛn we dɛn kin du ɔltɛm: dɛn kin chɛk di batri ɛvri mɔnt na di tɛlikɔm bays steshɔn dɛn, dɛn kin du intanɛnt rɛsistɛns sɔv we dɛn kin du ɛvri kwata fɔ di UPS bateri bank dɛn, ɛn dɛn kin chɛk di data sɛnta bak-ap batri dɛn wan wan tɛm. bay we yu kכmpεr intanεt rεsistεns bitwin wan wan sεl dεm insay wan batri string, dεn kin no wik sεl dεm — if wan sεl sho mכr dan 30% hכy rεsistεns pas di grup avεrej, i de warrant atεnshכn ivin if in absכlut valyu stil de insay spεk.
Wan intamɛdiet we na di lod vɔlɔt tɛst: fɔ aplay wan shɔt tɛm, mɔdaret-kɔrɛnt lod (tipikli tɛn amp fɔ sɔm sɛkɔn to tɛn sɛkɔn) ɛn mɛzhɔ di vɔlɔt sag. Dis na mɔ infɔmeshɔn pas opin-sɔrkwit vɔlɔt bɔt i fast pas ful kapasiti tɛst, we de mek i fayn fɔ fil asɛsmɛnt if batri kin sev frɔm di mɔnt kɔrɛnt sɔj we di ikwipmɛnt stat. Di PK59A stɔrɔj bateri tɛsta sɔpɔt dis lod tɛst mɔd — nɔ bateri rimɔv ɛn nɔ ɛkstend dischaj nid.
Tradishɔnal bateri tɛst bin yuz tri difrɛn divays dɛn: wan vɔltmita fɔ vɔltɛm, wan dischaj inschrumɛnt fɔ kapasiti, ɛn wan intanɛnt rɛsistɛns mita fɔ rɛsistɛns. Di prɔblɛm dɛn klia — bɔku divays dɛn, kɔmpleks waya, data we nɔ kɔrɛlat, ɛn rizɔlt dɛn we at fɔ sɛntesis. Fil injinia dɛn bin gɛt fɔ rayt tri difrɛn ridin dɛn, dɔn dɛn put dɛn insay wan sistem bak na di ɔfis. Ɛni mistek na da chen de — transkripshɔn, data ɛntrɛ, ɔ intapriteshɔn — min se di data nɔ alaynɛd.
Di PK59A intagret kapasiti, vɔlɔt, ɛn intanɛnt rɛsistɛns mɛzhɔmɛnt insay wan hanheld divays.

Wan bilt-in standad dischaj sɔrkwit de mek pɔsin ebul fɔ chɛk di kapasiti fɔ shɔt tɛm we dɛn nid am. Vɔltɛm de sampul tru wan ay-prɛsishɔn ADC. Ɔl di tri paramita dɛn de sho na di sem skrin, di rizɔlt dɛn de kɔrɛlat ɔtomɛtik wan, ɛn dɛn nɔ nid ɛni manual transkripshɔn.
In prɔsis, di PK59A de ad valyu tru fayn fayn ditel dɛn. I de sɔpɔt bɔku bateri kemistri dɛm — lid-asid, litiɔm-ayɔn, nikɛl-mɛtal haydrayd — ɔl dɛn kin mɛzhɔ wit wan inschrumɛnt, we de mek dɛn nɔ nid fɔ gɛt kemistri-spɛsifi k tul dɛm.

Insay fil bateri tɛst prɔsis, sɔm mistek dɛn we kin apin bak kin mek pɔsin lɔs we nɔ nid fɔ apin. We wi ɔndastand dɛn, dat kin mek wi nɔ gɛt rial prɔblɛm. Di fɔs mistek na fɔ mɛzhɔ vɔlɔt we nɔ gɛt intanɛnt rɛsistɛns. As wi bin dɔn tɔk, vɔlɔt de sho SOC nɔmɔ, nɔto rial bateri wɛlbɔdi.

Di sɛkɔn mistek na fɔ ignore di bateri string kɔnsistɛns. Batri string na jɔs lɛk aw in sɛl we wik pas ɔl. if intanεt rεsistεns vεryus bכku bitwin sεl dεm, di strכng go sag dכn kכtכf vכltεj di tεm we di hεy-kכrεnt dischaj de biכs fכ di barεl ifekt, ivin if εvri wan wan sεl de insay spεk pan absכlut rεsistεns. we yu de tεst wan strכng, כltεm mεzj כl tu di agrεgεt εn εvri wan wan sεl, pe kכl atεnshכn to sεl dεm we dεn rεsistεns deviayt mכr dan 30% frכm di grup avεrej.
