DFUN Battery Internal Resistance Measurement Technology: Precision Monitoring for Extended Battery Life

He hōʻailona koʻikoʻi no ka loiloi ʻana i ke ola olakino a me ka lawelawe ʻana o nā pila. I ka wā lōʻihi, piʻi mālie ke kūpaʻa kūloko, hoʻopilikia i ka hana. Hiki i kēia ke hopena i ka lohi o ka hoʻokuʻu ʻana, ʻoi aku ka nui o ka nalowale o ka ikehu, a me nā mahana hana kiʻekiʻe. ʻO ka mea kūikawā, ke ʻoi aku ka ikaika o loko ma mua o 25% o ka waiwai maʻamau, e emi nui ana ka nui o ka pākaukau, e hoʻololi ana i ka paʻa o ka ʻōnaehana. No laila, he mea nui ka nānā ʻana i ka ikaika o ka pākaukau i loko.

Nā ʻano maʻamau no ke ana ʻana i ke kūpaʻa kūloko

1. Keʻano hoʻokuʻu pololei (DC).

Hoʻopili kēia ʻano hana i ka hoʻokuʻu ʻana i ka pākaukau me kahi manawa kiʻekiʻe a me ka helu ʻana i ke kūpaʻa kūloko ma muli o ka hāʻule ʻana o ka volta. ʻOiai e hāʻawi ana i ka pololei ana kiʻekiʻe, hoʻoulu ia i nā hopena polarization i loko o ka pākaukau, e wikiwiki ana i ka ʻelemakule. ʻO ka hopena, ua hoʻohana mua ʻia kēia ʻano hana i ka noiʻi a me nā pae hana hoʻokele a ʻaʻole kūpono no ka nānā ʻana i ka wā lōʻihi.

2. Alternating Current (AC) Impedance Method

Ma ka hoʻohana ʻana i kahi ʻano ʻokoʻa o kahi alapine kikoʻī a me ka hoʻohana ʻana i ke kānāwai o Ohm a me nā loina capacitance, e ana kēia ʻano i ke kū'ē kūloko. ʻAʻole like me ke ʻano o ka hoʻokuʻu ʻana o DC, ʻaʻole ke ʻano o ka impedance AC i ka hōʻino ʻana i ke ola pākaukau a hāʻawi i nā hopena i emi iho ka hilinaʻi. ʻO nā ana i lawe ʻia ma ke alapine o 1kHz ʻo ia ka mea paʻa loa. Hoʻohana nui ʻia kēia ʻano hana i ka ʻoihana a loaʻa i ka pololei kiʻekiʻe, me ka hapa o ka hewa ma waena o 1% a me 2%.

ʻO DFUN's Innovative Solution: AC Low Current Discharge Method

Ua hoʻomohala ʻo DFUN i kahi hoʻomaikaʻi hou i ke ʻano kuʻuna AC impedance—ke ʻano AC Low Current Discharge Method. Ma ka hoʻohana ʻana i kahi ʻano ʻokoʻa ʻaʻole i ʻoi aku ma mua o 2A a me ke ana pololei ʻana i ka fluctuations o ka uila, hiki ke helu pololei ʻia ke kūpaʻa kūloko o ka pākaukau i kahi manawa pōkole (ma kahi o hoʻokahi kekona).

Nā Pōmaikaʻi Nui:

• ʻO ka pololei kiʻekiʻe: kokoke i ka 1% ka pololei o ke ana ʻana, me nā hualoaʻa kokoke like me nā hōʻailona o nā ʻaoʻao ʻekolu e like me Hioki a me Fluke.

Kue Kuloko	2V Battery: 0.1 ~ 50 mΩ	Hiki ke hana hou: ±(1.0% + 25 µΩ)	Hoʻoholo: 0.001 mΩ
	12V Battery: 0.1 ~ 100 mΩ

• ʻAʻohe hopena i ke ola olakino: Me ka haʻahaʻa haʻahaʻa a me ka liʻiliʻi o ka hoʻokuʻu ʻana amplitude, ʻaʻole kēia ʻano hana e hōʻeha i ka pākaukau a i ʻole e wikiwiki i ka ʻelemakule.

• Ka nānā ʻana i ka manawa maoli: hiki iā ia ke loaʻa i ke kūlana pākaukau i ka manawa maoli, e pale pono i ka hoʻohaʻahaʻa ʻana i ka hana ma muli o ka piʻi ʻana o ke kūpaʻa kūloko.

• Mea Hoʻohana Nui: ʻAʻole pili kēia ʻenehana i nā pākaukau lead-acid akā pono pū kekahi no ka nānā ʻana i ke kūpaʻa kūloko i nā ʻano pākaukau ʻē aʻe.

E hōʻoia i ka noho ʻana o kāu mau pākahi i ke kūlana maikaʻi loa, e hoʻonui ai i ka paʻa a me ka hilinaʻi o kāu ʻōnaehana mana.
