Tempere ina toɗɗii kala golle nder batiri — gila e njuuteendi mbayliigu elektoro-kimikaaji haa e njuuteendi njuuteendi elektorolit haa e darnde filmo SEI. Famde batte nguleeki ko huunde nde foti wonde ngam jarribaade e toppitaade batteeji ɗii no moƴƴiri. Ndee winndannde ina hollita ko waɗi nguleeki ina foti waɗteede hakkille no voltage nii.

No nguleeki battinirta e batteeji : Gila e kemikal haa e mbaadi kuutorteendi

Temperature ina jogii batte kuuɓtodinɗe e golle batte. Fotde kala golle ndernderiije — njuuteendi mbayliigu elektoro-kimikaaji, njuuteendi elektorolit, darnde filmo SEI — ina jokkondiri e nguleeki. Famde ɗeen batte ko huunde nde fotaani wonde ngam ƴeewndaade e toppitaade batte no haanirta nii.

E nguleeki les (les 0°C), mbaawka huutoraade ina ustoo no feewi. Wonande batteeji asid-plomb, e 0°C mbaawka huutoraade ko hedde 75% e tolno ; to -10°C, ko ina wona 50% ; to -20°C, ina gasa tawa ko 30% tan. Ɗuum wonaa bonnugol duumingol — nguleeki les ina usta jolngo iyon elektorolit, ina leeltina kinetik reaksiyoŋ, ina ɓeyda polarisaasiyoŋ, ina usta mbaawka keɓaaka e sahaa. Capaato ina heɓtoo so nguleeki ɓeydiima. Kono tan, ɓuuɓol toowngol e nguleeki les ina waawi addande ɓuuɓol ngol ustaade no feewi, kadi ina addana kaɓirɗe ɗee uddude, hay so tawii noon mbaawka heddii ina heddii.

E nguleeki toowki (dow 30°C), mbaawka huutoraade ina ɓeydoo e sahaa (fotde 10% e ɓeydagol 10°C wonande asid-plomb), kono njoɓdi ndii ina yaawi bonnude nguurndam. Nguurndam ɓuuɓɗam asid-plomb e 25°C ko hedde duuɓi 5-8 ; kala 10°C ina ummoo ko ina tolnoo e feccere nguurndam heddiiɗam — e 35°C, ma a taw ko duuɓi 2-4 tan heddii. Ko ɗum waɗi nguleeki toowki ina yaawi ɓuuɓde gris e njaru ndiyam elektorolit. Batteeji litiyum-iyon ina poti ɓuuɓde — nguleeki toowki ina yaawi ustude filmo SEI e oksidaasiyoŋ elektorolit, ina addana ɗum yaawde ustaade mbaawka e ɓeydagol jaawngol e nder mum.

Ko ɗum waɗi nafoore ƴeewndo nguleeki e nder jarribooji batteeji ko nii : njeñtudi jarribo ƴettaango e nguleeki ceertuki nanndaani. So tawii nguleeki weeyo winndaaka e nder jarribo, ƴeewndo caggal ɗuum waawaa anndude so tawii waylooji reentaare ina kollita duuɓi walla ko waylooji nguleeki tan. Yeru, reentaare fotnde e ndunngu ina waawi ɓurde e ndunngu wonaa sabu batte mum ina duumii, kono ko sabu nde ɓuuɓnoo.

Njoɓdi nguleeki: Waɗde Dowlaaji ina nanndi e yontaaji

Njoɓdi nguleeki ko karallaagal keeringal e jarribo batte. Faandaare mayre ko ittude batte nguleeki mbele doosɗe pooɗanooɗe e sahaaji ceertuɗi ina mbaawa yerondireede. Kuulal ngal : huutoraade 25°C ngam wonde nguleeki tuugnorgal, e njeñtudi laaɓtundi tuugiindi e mbayliigu tuugnorgal.

Ngam jarribaade doolnugol ndernderiwol, feere mbayliigu tippudi ko : kala 10°C gonɗo e tuugnorgal ina rewna jaŋtol ngol ko ina tolnoo e 30% wonande batteeji asid-plomb walla 15% wonande batteeji litiyom-iyon. Yeru, ƴoƴre ndernderiire fotnde e 10°C ko 50 mΩ ina feewna fotde 35 mΩ e 25°C tuugnorgal. Ɗuum ina addana ƴeewndo toowngo hakkunde janngugol ndunngu e ndunngu.

Ngam jarribaade voltage, njoɓdi nguleeki ina foti wonde nafoore. Batiri udditirɗo-circuit kadi ina seerti e nguleeki — ko ina wona 3mV e 1°C wonande asid-plomb. So tawii ko njoɓdi, 12,6V fotde 5°C e 12,6V fotde 35°C ina mbaawi yahdude e teddeendi SOC ceertundi ko ɓuri 10%.

PK59B ina waɗi mahngo nguleeki mahngo e sensor nguleeki gonɗo e mbaydi ngam fooɗtude nguleeki dow batteeji e sahaa gooto. Tester oo ina feewna jaŋɗeele ɗee e kuutoragol jokkorgal njoɓdi gonngal e dow mum — alaa ko hiisa e junngo haani. E nder golle, ɗum ina usta no feewi ŋakkeende safaara saabiinde mbayliigu nguleeki.

Anomaliiji nguleeki : Signal jeertinaango ɓurngo yaawde e reentaade

E nder golle batteeji, anomaaliiji nguleeki ina keewi feeñde ko adii nde doolnugol nder mum ina ɓeydoo walla mbaawka mum ina yiyee ina ustoo. Yiytude anomaluuji nguleeki ko yaawi ina waawi haɗde ŋakkeende keewnde.

Ko ɓuri heewde e mbaydiiji anomaali nguleeki ina mbaɗi : cellal gootal e nder doggol ina doga ina ɓura woɗɓe nguleeki no feewi e sahaa nde jolnata (ina hollita sulfaasiyoŋ ndernderiijo juutɗo walla tiiɗɗo) ; denndaangal ɓoggol ngol ina doga ina ɓuuɓna e nder charge float (ina hollita voltage float ina settee no feewi); ɓuuɓgol nguleeki seeɗa caggal nde yalti (ina hollita ɓuuɓri ndernderi ɓurtundi). So tawii ɗeen anomaaliiji nguleeki ina mbaawi nanngeede ko yaawi, peeje moƴƴe ina mbaawi ƴetteede hade mum ustaade — dogdu nguleeki walla ŋakkeende mbaawka haa zero.

Laawol yiytugol ngol fawii ko e njuɓɓudi kaɓirɗe. Laawol ɓurngol hoybude ngol ko jarriborde batiri jogiinde mbaawka nguleeki (hono PK59B), winnditaade nguleeki e sara kala jarribo reentaare ndernderiire. Ko ɓuri yahrude yeeso ko njuɓɓudi ƴeewndo nguleeki to internet tawa ina waɗi sensorji e kala cellal, dokke ina njokki e jolneede e host ƴeewndo. Ko ɓuri heewde e nokkuuji telefoŋaaji e UPS, jarribo nguleeki sahaa e sahaa fof tawa ina yahdi e jarribo reentaare ndernderiire ina heddi ngam nanngude ko ɓuri heewde e anomaliiji nguleeki.

Toɓɓe gollorde ladde ngam jarribaade nguleeki

Teskuyaaji nguleeki ina nanndi e ko weeɓi kono ina njogii defte gollorɗe potɗe teskeede. Ko adii fof : hol to foti fotde. Peccitagol nguleeki nder batiri wonaa gootum — terminaluuji e jokkondire ina ndoga ɓura ɓanndu nduu nguleeki sabu nguleeki Joule ummoraade e reentaade jokkondiral. Ko ɗum waɗi, fotde to ɓanndu batiri (hakkunde ɓalndu) ko ɗum woni tuugnorgal gadanal, tawa nguleeki timmungal ko ɗum woni ɗiɗaɓal. So tawii nguleeki timmundi ɓurii nguleeki ɓanndu ko ɓuri 10°C, jokkondire ina gasa tawa ina ɓuuɓi, ina poti tiiɗtineede.

Ɗiɗaɓere : nde foti fotde. Nguleeki batiri ina ɓeydoo e sahaa charging, kadi e sahaa decharge, seeɗa seeɗa ina artira e ambient so ina fooftoo. Ngam nannditinde hakkunde jarribooji, winndu nguleeki e nokku gonɗo e nder cirƴam jarribo — yeru, sahaa kala e nder charge float stable, walla sahaa kala e joofnirde decharge. So toɓɓe pooɗondiral ina ceerti, doosɗe nguleeki ina caɗta ƴeewteede.

Tataɓol : hol no firtirtee. Janngugol nguleeki gootol ina hollita tan ko sahaa fotde, ina foti ƴeewteede e nguleeki weeyo. So tawii nguleeki ɓanndu batiri ɓurii nguleeki weeyo ko ɓuri 5°C, nguleeki ndernderi kii ina waɗa hay so tawii nguleeki timmundi ina famɗi haa jooni. So nguleeki cellal nder ɓoggol ina seerti ko ɓuri 3°C, ŋakkeende cellal ina woodi.

Wasiyaaji kuuɓtodinɗi : Naatde e nguleeki e nder ƴeewndo cellal batte

Wonande kippuuji toppitiiɗi, naatnee jarribo nguleeki e nder laabi toppitiiɗi batte goodɗi ɗii. Kippuuji jogiiɗi PK59A ina mbaawi ɓeydude heen termometre infrared ngam ɓeydude nguleeki ; ekipaaji jogiiɗi PK59B ina kuutoroo sensor gonɗo e mbaydi to bannge. Kuutorgal fof, coktirgal ngal ko winndude nguleeki e bannge kala jarribo.

Wonande soodooɓe e nokkuuji jogiiɗi mbayliigu nguleeki weeyo (diiwanuuji ɓuuɓɗi, nokkuuji ɓuuɓɗi jogiiɗi yontaaji nay ceertuɗi), ardineede mbaadiiji jogiiɗi mbaawka jarribaade nguleeki (PK59B). Dowlaaji nguleeki ŋakkuɗi ina usta no feewi ƴeewndo njeñtudi jarribo — aɗa waawi waɗde heen waktu e doole goote e jarribo kono a waawaa anndude so njeñtudi ndii ina woodi tawa aɗa jogii ngonka nguleeki.

E ndaarde yeeso, toppitagol batteeji ina yahra yeeso feewde e ƴeewndo kuuɓtodinngo parametruuji keewɗi — reentaare ndernderiire, doole, nguleeki, daartol charge-discharge, e ngonkaaji nokkuuji kawraaɗi e ƴeewndo dokke ngam feewnude limre cellal batteeji kuuɓtodinnde. Temperature ko huunde nde alaa ko waawi heen wonde so wonaa e nder ooɗoo sifaa. View the Battery Test Instruments Collection
