A waawaa ñaawde batte e limoore wootere. Juumre ɓurnde heewde ko sikkude wonde doole toowɗe firti ko batiri celluɗo — batiri jooɗiiɗo e dow ŋoral fotde lebbi jeegom tawa ina waɗi diƴƴe teeŋtuɗe ina waawi hollirde haa jooni doole cirkooji udditiiɗi ɓadtiiɗi timmuɗi tawa mbaawka mum kuutorteeka ina ustoo e feccere. Ko wayno noon, batiri ɓooyɗo mo ujunnaaje ujunnaaje cirkooji ina waawi hollirde doole jaɓaaɗe kono ina ustoo les taƴre les jolngo. Ɗeeɗoo yeruuji ɗiɗi ina kollita wonde ñaawoore parametru gooto ina waawi addande neɗɗo ƴeewndo ngo moƴƴaani : mbaawka, doole, e doole ndernderiije fof ina poti ƴeewteede e nder nokku gooto.

Capanɗe, Voltage, e Resistance nder: Dimensiyonji tati cellal batte

Capacity ina hollita no semmbe batiri oo waawirta jogaade haa jooni, ko ɓuri heewde e mum ko ampere-hours (Ah) — ko heewi e doole ɗe mbaawi yetteede e nder sarɗiiji ɓuuɓɗi. Capacity fade ko ko ɓuri laaɓtude e kollirooje duuɓi batte. Batiri mo 100Ah ina waawi rokkude tan 70Ah caggal duuɓi tati ina jogii ngonka cellal (SOH) 70%. Fooyre mbaawka ina ɗaɓɓi udditgol timmungol to jolngo taƴngo, ko ɗum ƴettata waktuuji keewɗi — ko ɓuri heewde ko fotaani ƴeewteede ñalnde kala ko yaawi, kono ko huunde himmunde ngam fooɗtude jaɓgol, wiɗtooji toppitiiɗi hitaande kala, e pellital joofgol nguurndam.

Reenngo ndernderiijo ina hollita ƴoƴre nder batiri, fotnde e miliyom (mΩ). Ina waɗi geɗe tati : doolnugol polarisaasiyoŋ (gila e kinetik reaksiyoŋ elektoro-kimikaaji), doolnugol ohmik (gila e doolnugol kaɓirɗe elektoronik e jokkondire jokkondirɗe), e doolnugol elektorolit. Batteeji kesi ina keewi hollirde semmbe ndernderiijo e nder sappooji miliyoŋaaji walla les. So limre cirƴam ɓeydiima, elektorolit ina famɗi, reentaare ndernderiire ina ɓeydoo seeɗa seeɗa. Faandaare tiiɗnde ndee ko wonde reentaade ndernderiire e fadde mbaawkaaji ngonaa lineere — reentaade ina wayloo seeɗa no feewi e feccere adannde nguurndam, caggal ɗuum ina yaawi e feccere ɗimmere ndee. So mbaawka ina yiyee ina ustoo, ina gasa tawa reentaare ndee ina sowoo laabi ɗiɗi walla ko ɓuri ɗum. Ɗuum ina addana reentaare ndernderiire wonde huunde moƴƴere ngam jeertinde ko yaawi wonaa ñaawoore sakkitiinde.

Voltage woni parametru ɓurɗo laaɓtude kono kadi ɓurɗo weeɓde janngeede. Voltage cirkowol udditiingol (OCV) ina hollita tan ngonka jolngo (SOC) — no semmbe heddorii — wonaa no batte ɗee mbaawirta rokkude tigi rigi. Batiri asid-plomb 12V e 12,6V ina heewi ; e 12,0V ko hedde 75% SOC ; to 11,4V ko ina wona 25% SOC ; to 10.5V ina ɓadii ustaade. Kono SOC e SOH ngonaa huunde wootere — batiri to SOC toowɗo e reentaare ndernderiire toownde maa sag les voltage gollorɗo e sahaa nde jolngo waɗaa, kaɓirɗe ɗee maa uddu ko aldaa e ƴeewde. Voltage ina foti firteede sahaa kala wondude e jolngo, rewrude e jarribo jolngo walla jarribo mbaawka, hay dara rewrude e jolngo udditiingo tan.

Nde kuutorto-ɗaa jarribo mbaawka vs. jarribo reentaare nder

Kuutorɗe ceertuɗe ina ɗaɓɓi laabi jarribooji ceertuɗi, kadi suɓaade feere moƴƴere ina bonna waktu, ina waawi waasde caɗeele goonga. Fooyre mbaawka (full discharge) ko mbaydi kaŋŋe ngam anndude cellal batiri, kono ina jogii sarɗiiji ɗiɗi : ina ɗaɓɓi ƴettude batte timmuɗe, ɗum firti ko ƴettude system online tawa ko e laylaytol ; e ɗum ƴetta waktuuji juutɗi — batte 100Ah ɓuuɓɗe e 5A ina ɗaɓɓi waktuuji 20. Fooyre mbaawka ina foti wonde : jaɓgol batteeji kesi, wiɗtooji toppitiiɗi hitaande kala, anndinde joofgol nguurndam hade batteeji lomtineede, e ƴeewndo luggiɗngo e nder ƴeewndo ŋakkeende.

Fooyre reentaare ndernderiire ina yaawi, nde bonnataa, ina waawi wonde e internet. Fotde ƴettata ko leƴƴanɗe tan, alaa ko ɗaɓɓi so wonaa ittude batiri e golle, tee alaa ko ɗaɓɓi so wonaa jolngo. Ɗum waɗi ɗum ko huunde moƴƴere ngam ƴeewndorɗe kuuɓtodinɗe : ƴeewndorɗe batteeji lewru kala to nokkuuji telefoŋaaji, wiɗtooji reentaare nder bankeeji batteeji UPS kala lewru, e ƴeewndo sahaa e sahaa fof batteeji baɗeteeɗi e nokkuuji domen. So en ƴeewtindiima doolnugol ndernderiwol hakkunde celule gooto-gooto e nder doggol batte, celule ɗe ngalaa semmbe ina mbaawi anndeede — so celule goote ina kollita doolnugol ɓurngol 30% e tolno fedde ndee, ina foti waɗteede hakkille hay so tawii nafoore mum timmunde ina woni e nder spec.

Laawol hakkundeewol ko jarribo jolngo : waɗde jolngo juutngo, ɓuuɓngo (ko ɓuri heewde ko sappooji ampereeji e nder leƴƴanɗe seeɗa haa leƴƴanɗe sappo) e pooɗondiral saggal jolngo. Ɗuum ɓuri humpitaade ko jolngo cirkowol udditiingol kono ɓuri yaawde e jarribooji baawɗe timmude, ɗum noon ina moƴƴi e ƴeewndo ladde so tawii batiri ina waawi wuurde e jolngo jolngo ngo sahaa gooto so kaɓirɗe puɗɗiima. Tester batte desorɗe PK59A ina wallita e ngalɗoo mbaadi jarribo teddeendi — alaa ittugol batte e alaa ko yaaji e ustude.

PK59A: Naatde e Parametruuji tati e nder kaɓirgal gootal

Fooyre batteeji gaadanteeji kuutortoo ko kaɓirɗe tati ceertuɗe : voltmeter ngam ƴeewde tolno nguleeki, kuutorgal ɓuuɓngal ngam ƴeewde mbaawka, e meeteer ɓuuɓɗo nder ngam ƴeewde ɓuuɓol. Caɗeele ɗee ina laaɓi — kaɓirɗe keewɗe, kaɓirɗe caɗtuɗe, dokke ɗe njokkondirtaa, e njeñtudi ndi caɗtundi sinndeede. Injiniyankooɓe ladde ina poti winndude jaŋte tati ceertuɗe, caggal ɗuum naatna ɗe e nder system ngarta to biro. Kala boowal e nder oon cakkital — binndol, naatgol dokke, walla firo — firti ko dokke ɗee njiidaani.

PK59A ina renndini mbaawka, doole, e fotde reentaare ndernderiire e nder kaɓirgal gootal juɓɓungal. Laawol mum fotde teskinngol huutortoo ko jokkondire 4 (Kelvin) ngam fooɗtude doolnugol ndernderiwol, ittude batte doolnugol jarriborgol. Circuit de décharge standard mahaaɗo ina addana hoolkisaade decharge juutɗo e mbaawka so ina haani. Voltage ina samplee rewrude e ADC toowɗo. Parametruuji tati ɗii fof kolliraama e ekran gooto, njeñtudi ndii ina jokkondiri otomatik, tee alaa ko haani winndeede e junngo.

E nder golle, PK59A ina ɓeyda nafoore rewrude e detal ɓurngal laaɓtude. Ina wallita e kemikaluuji batteeji keewɗi — asid-plomb, litiyom-ion, hidriid nikel-metal — fof ina pooɗee e kuutorgal gootal, ina itta haaju kuutorɗe kemikal keertiiɗe. Ina moofta njeñtudi jarribo ngam ƴeewndaade e dokke daartol. Kollitgol maggol ina rokka ñaawoore laaɓtunde — PASS / WARNING / FAIL — wonaa tan jaŋngugol raw, accude gollotooɓe ladde ƴeewtaade ngonka batteeji e ƴeewndo. Ina waɗi kadi mbayliigu nguleeki otomatik, feewnude jaŋɗeele e nder nokkuuji toowɗi walla lesɗi ngam ngonkaaji weeyo ɗii mbayla njeñtudi ndii.

Juumre jarribo ladde nayi ɓurnde heewde

E nder golle jarribooji batteeji ladde, majjere keewnde rewrude e majjere nde alaa nafoore. Famde ɗe ina haɗa caɗeele goonga. Juumre adannde ndee ko fotde voltage tawa alaa ko reentoo e nder mum. No yeewtiraa nii, voltage ina hollita tan SOC, wonaa cellal batte tigi rigi. Gollotooɓe toppitiiɓe ko heewi e hoolaare doolnude — miijaade doolnude no woorunoo firti ko batte moƴƴe — ina njokki golloraade batteeji ɗi doole mum en ndernderiije ina toowi no feewi, haa kaɓirɗe ɗee njuumta e sahaa caɗtuɗo.

Juumre ɗiɗmere ndee ko yejjiteede e jokkondire batte. Ɗatal batiri ina moƴƴi tan no cellal mum ɓurngal leelde nii. So tawii reentaare ndernderiire ina seerti no feewi hakkunde cellal, ɓoggol ngol maa sag les cutoff voltage e nder sahaa ɓuuɓol toowngol sabu batte barel, hay so tawii kala cellal gootol ina woni e nder spec e reentaare timmunde. So aɗa ƴeewtoo ɓoggol, sahaa kala fotndu aggregate e kala cellal gootol, waɗ heen hakkille no feewi e cellal ngal reentaare mum ɓuri 30% e tolno fedde ndee.

Juumre tataɓere ndee ko waasde winndude e ƴeewtaade dokke. Heewɓe e gollotooɓe e nder ladde ina timmina jarribo, ina njannga limooje, ina njalta — dokke ɗee meeɗaa naatde e njuɓɓudi toppitiindi. E cirƴam jarribo aroore, alaa fof no anndirten ko wayli e nder hakkundeere ndee. Laawol laaɓtungol ko winndude reentaare ndernderiire e doolnude caggal kala jarribo, mahde winndannde cellal limre waktuuji wonande kala cellal. So tawii cellal hollitii ƴellitaare reentaare yaawnde, lomtinande ina foti yuɓɓineede hade mum ustaade.

Juumre nayaɓere ndee ko ƴeewtaade batte nguleeki weeyo. Batiri nder reentaare e mbaawka fof ina tiiɗi e nguleeki. Wonande batteeji asid-plomb, kala ɓeydagol 10°C ina usta semmbe nder mum fotde 30%, ina ɓeyda semmbe fotde 10% ; ko rewi heen koo ina waɗa e nguleeki les. So tawii ko njoɓdi nguleeki, jaŋɗeele reentaare ƴettaaɗe e yontaaji ceertuɗi nanndaani. Feere mbayliigu nguleeki PK59A ina woodi teeŋti noon ngam safrude ndee caɗeele.

Wasiyaaji kuuɓtodinɗi wonande kippuuji toppitiiɗi e soodooɓe

Toppitagol batte kuuɓtodinngol ina yaaji e fotde tan doole. Golle jarribo timmuɗe ina poti wonde : jarribo jaɓgol batteeji kesi (tabitinoowo SOH gadano oo e 100%), ƴeewndorɗe reentaare ndernderiije sahaa e sahaa fof e nder golle (sappoɓal kala ngam huutoraade ɗum e kala sahaa, lewru kala ngam telefoŋaaji), ƴeewndorɗe mbaawkaaji hitaande kala (20% e cellal timmungal), e ƴeewndorɗe ɓeydooje doole e nder nokkuuji.

So a suɓiima kaɓirɗe jarriborɗe, coggu tan fotaani wonde ngoƴa. Kuutorgal gootal kuuɓtidinngal ngam fooɗtude mbaawka, doole, e doole ndernderiije ɓuri hoybude, ɓuri hoolaade, kadi ɓuri famɗude waktuuji e kuutorɗe tati kuutortooɗe golle goote. Nafoore mawnde kaɓirgal hono PK59A wonaa tan laaɓal fotde — ko mbaawka timminde ƴeewndo batte timmunde e nder hojomaaji joy e nokku waktuuji ɗiɗi wiring, decharge, e transcription data.

Soodooɓe ina poti kadi waɗtude hakkillaaji mum en e defte ɗe njiyataa no feewi e nder kaɓirɗe yeeyde : mbele kaɓirgal ngal ina wallita e yaltinde dokke ngam jokkondirde e njuɓɓudi toppitagol ; mbele jolɗe batte ɗee ina njaɓɓa sifaaji terminal ceertuɗi tawaaɗi e nder ladde ndee ; mbele jarribooji e internet (no-remove) ina mballita ; e so tawii sarwisaaji gartirgol e kalibraasiyoŋ ina keewi — kuutorɗe jarriborɗe e koye mum en ina ɗaɓɓi kalibraasiyoŋ sahaa e sahaa fof. Ɗeeɗoo defte ina kollita so tawii kaɓirgal ngal ina huutoree tigi rigi walla ina joofna yejjiteede e nder lowre. View the Battery Test Instruments Collection
