He aha ka pākēneka o ka waiwai o ka pākaukau ʻoi aku ka maikaʻi o ka hoʻolōʻihi ʻana i ke ola o ka pākaukau?

E pili ana i ka nīnau mua: He aha ka pākēneka o ka paepae pākaukau i mea e hoʻolōʻihi ai i ke ola pākaukau?
Nīnau maoli kēia e pili ana i ka hopena o nā SOC like ʻole (SOC = hiki ke loaʻa / nominal capacity) ka waiho ʻana o nā pā lithium-ion ma ka hiki ke pā;ʻO ka mea mua e akaka ai, ʻo nā SOC ʻokoʻa e pili ana i ka attenuation o ka pākaukau i ka wā o ka mālama ʻana.He hopena kona, a heʻokoʻa ka hopena kiko'ī e like me nā huahana likeʻole;ma muli o nā kumu kūʻai, e loaʻa i kēlā me kēia mea hoʻolako lithium-ion a me ka mea hana terminal nā koi like ʻole no nā huahana like ʻole;akā, no nā pākahi lithium-ion, ʻokoʻa ka hopena o nā SOC i ka pā.Hoʻohana mau ʻia ke kānāwai kumu o ka hopena o ka mālama ʻana i ka wā kahiko, akā aia kekahi mau ʻokoʻa ma waena o nā huahana like ʻole;
ʻO ke kiʻi 1abc ke kiʻina hana mālama o nā pā lithium-ion me ʻekolu mau ʻōnaehana waiwai i kūʻai ʻia i kēia manawa ma nā SOC like ʻole a me ka mahana, a hiki ke ʻike ʻia ke kānāwai kumu I ka piʻi ʻana o ka SOC, piʻi ka pohō o ka mālama ʻana, piʻi ka mahana mālama, a piʻi aʻe ka pohō o ka wā kahiko, a ʻoi aku ka nui o ka hopena o ka wela kiʻekiʻe i ka nalowale ʻana o ka wā kahiko o nā pā lithium-ion ma mua o ka SOC.

Hōʻike ka Figure 2 ma lalo nei i ka hana kahiko o ka mālama ʻana i nā ʻano pākahi lithium-ion ma lalo o nā kūlana like ʻole i hōʻuluʻulu ʻia i loko o kahi puke loiloi.Hiki ke ʻike ʻia ua like like ke kānāwai me ka mea i hōʻike ʻia ma ke Kiʻi 1.

ʻElua mau ʻōnaehana electrochemical i nā ʻeke kelepona: ternary (NCM) a me ka lithium cobalt oxide (LCO).No ka hoʻolōʻihi i ke ola lawelawe, he mea nui loa ʻaʻole e ʻike i nā mahana kiʻekiʻe.ʻAʻole kiʻekiʻe a haʻahaʻa paha ka SOC.ʻAʻole ʻōlelo ʻia e mālama i ka SOC haʻahaʻa loa, no ka mea, e loaʻa i nā pā lithium-ion ke ʻano hoʻokuʻu ponoʻī i ka wā o ka mālama ʻana, a ʻo ka pilikia o ka hoʻokuʻu ʻana o ka pākaukau inā haʻahaʻa loa ka SOC, ʻo ia hoʻi. e hoʻoulu i nā pilikia like ʻole i ka pākaukau, no laila ua ʻōlelo ʻia ʻo 20-25 ℃, 40-60% SOC mālama.Hiki iā ʻoe ke hoʻomanaʻo pono no nā huahana i kūʻai ʻia me nā pā lithium-ion, ʻo ka nui o ka pākaukau o ka pahu mua ma waena o 40-80%.ʻO ka nīnau ʻelua, i ka wā e hoʻopili ʻia ai ka pakuhi i kahi lako mana waho, ʻaʻole hāʻawi ka pākaukau i ka mana, no laila ʻaʻole ia e pili i kāna hana.
