Okwangoku, indlela yokulinganisa ukunganyangeki ngaphakathi ibhetri isetyenziswa ikakhulu kumzi mveliso. Kwizicelo zoshishino, umlinganiselo ochanekileyo wokuchasana kwangaphakathi kwebhetri ufezekiswa ngezixhobo ezikhethekileyo. Mandithethe malunga nendlela yokulinganisa ibhetri yangaphakathi esetyenziswa kushishino. Okwangoku, zimbini iindlela eziphambili zokulinganisa ukuchasana kwebhetri kwangaphakathi kwishishini:

1. I-DC yokukhupha indlela yokulinganisa ukuchasana kwangaphakathi
Ngokwefomula yomzimba r = u / I, izixhobo zovavanyo zinyanzela ibhetri ukuba idlulise i-DC yangoku rhoqo ngexesha elifutshane (ngokubanzi imizuzwana emi-2-3) (okwangoku kusetyenziswa ubukhulu obungama-40a-80a ngokubanzi) , kwaye i-voltage kwibhetri ilinganiswa ngeli xesha , Kwaye ubale ukuchasana kwangaphakathi kwangoku kwebhetri ngokwefomula.
Le ndlela yokulinganisa ichaneka ngokuchanekileyo. Ukuba ilawulwa ngokufanelekileyo, impazamo yokuchaneka komlinganiselo inokulawulwa ngaphakathi kwe-0.1%.
Kodwa le ndlela ineziphene ezicacileyo:
(1) Kuphela ziibhetri zomthamo omkhulu okanye ii-accumulators ezinokulinganiswa. Iibhetri ezincinci zomthamo azinakulayishwa ngombane omkhulu we-40A ukuya kuma-80A kwimizuzwana emi-2 ukuya kwemi-3;
(2) Xa ibhetri idlula umsinga omkhulu, i-electrodes ngaphakathi kwebhetri iya kuhlanjululwa, kwaye i-polarization iya kuba yinto enzima, kwaye ukuchasana kuya kubonakala. Ngoko ke, ixesha lokulinganisa kufuneka libe lifutshane kakhulu, ngaphandle koko ixabiso elilinganisiweyo lokuchasana langaphakathi liya kuba nephutha elikhulu;
(3) Umbane ophezulu odlula kwibhetri uya kuwonakalisa i-electrode yangaphakathi yebhetri ukuya kumlinganiselo othile.
2. Uxinzelelo lwe-AC lwehla umlinganiselo wokuchasana wangaphakathi
Kuba ibhetri ilingana nesixhathisi esisebenzayo, sisebenzisa imvamisa eqingqiweyo kunye yangoku esisigxina kwibhetri (okwangoku i-1kHz frequency kunye ne-50mA encinci ngoku isetyenziswa ngokubanzi), emva koko isampula umbane wayo, emva kothotho lokuqhubekeka njengokulungiswa nokucoca, Bala ukuxhathisa kwangaphakathi kwebhetri ngokusebenzisa isiphaluka seamplifier yokusebenza. Ixesha lokulinganisa ibhetri yombane we-AC wehla indlela yokulinganisa ukuxhathisa kwangaphakathi lifutshane kakhulu, ngokubanzi malunga ne-100ms. Ukuchaneka kwale ndlela yokulinganisa kulungile kakhulu, kwaye impazamo yokuchaneka kwemilinganiselo ngokubanzi iphakathi kwe-1% -2%.
Iingenelo kunye nokungalunganga kwale ndlela:
(1) Phantse zonke iibhetri, kubandakanywa iibhetri ezinomthamo omncinci, zinokulinganiswa nge-AC voltage drop internal resistance measurement method. Le ndlela idla ngokusetyenziselwa ukulinganisa ukuxhathisa kwangaphakathi kweeseli zebhetri ye-notebook.
(2) Ukuchaneka komlinganiselo wendlela yokulinganisa i-AC yombane we-voltage ichaphazeleka ngokulula ngumbane we-ripple current, kwaye kukho nokuphazamiseka kokuphazamiseka kwangoku kwe-harmonic. Olu luvavanyo lwesakhono sokuchasana nokuphazamiseka kwesekethe yesixhobo sokulinganisa.
(3) Le ndlela ayinakonakalisa kakhulu ibhetri ngokwayo.
(4) Ukuchaneka kwendlela yokulinganisa i-AC voltage drop iphantsi kune-DC yokukhupha indlela yokulinganisa yangaphakathi.
