Ngā Pūrongo - Te Awhe Ngaohiko o te Kaiwhakahaere: Te Mea Matua ki te Hototahi Pūhiko EV me te BMS

He maha ngā kaipupuri waka hiko e whakaaro ana he aha te mea e whakatau ana i te ngaohiko whakahaere o tā rātou waka - ko te pākahiko, ko te motuka rānei? He mea whakamiharo, ko te whakautu kei te kaiwhakahaere hiko. Mā tēnei wāhanga nui ka whakatū te awhe whakahaere ngaohiko e whakatau ana i te hototahi o te pākahiko me te mahi whānui o te pūnaha.

Kei roto i ngā ngaohiko EV paerewa ngā pūnaha 48V, 60V, me te 72V, ia pūnaha he awhe mahi motuhake:

Ko ngā pūnaha 48V e mahi ana i waenga i te 42V-60V
Ka mahi ngā pūnaha 60V i roto i te 50V-75V
Ka mahi ngā pūnaha 72V me ngā awhe 60V-89V

Ka taea e ngā pūmana teitei te whakahaere i ngā ngaohiko neke atu i te 110V, ka nui ake te ngāwari.

Ka pā tika te ātete ngaohiko o te kaiwhakahaere ki te hototahitanga o te pākahiko lithium mā te Pūnaha Whakahaere Pūhiko (BMS). Ka mahi ngā pākahiko lithium i roto i ngā papa ngaohiko motuhake e rerekē ana i ngā huringa utu/tuku. Ina nui ake te ngaohiko o te pākahiko i te rohe o runga o te kaiwhakahaere, ina heke rānei ki raro i tōna paepae o raro, e kore te waka e tīmata - ahakoa te āhua utu tuturu o te pākahiko.

Whakaarohia ēnei tauira o te ao tūturu:

Ka eke te pākahiko lithium nickel-manganese-cobalt (NMC) 72V me ngā pūtau 21 ki te 89.25V ina utua katoatia, ka heke ki te 87V i muri i te hekenga o te ngaohiko ara iahiko. Waihoki, ka eke te pākahiko lithium rino phosphate (LiFePO4) 72V me ngā pūtau 24 ki te 87.6V i te utu katoa, ka heke ki te 82V. Ahakoa kei roto tonu ngā mea e rua i ngā rohe o runga o te kaiwhakahaere, ka puta ngā raruraru ina tata te tukunga o ngā pākahiko.

Ko te take nui ka puta ina heke te ngaohiko o te pākahiko i raro i te paepae iti rawa o te kaiwhakahaere i mua i te whakahohenga o te tiaki BMS. I tēnei horopaki, ka āraihia e ngā tikanga tiaki o te kaiwhakahaere te tukunga atu, ka kore ai e taea te whakamahi i te waka ahakoa kei te mau tonu te kaha e taea ana te whakamahi i te pākahiko.

Mā tēnei whanaungatanga e whakaatu he aha me rite te whirihoranga pākahiko ki ngā whakaritenga a te kaiwhakahaere. Ko te maha o ngā pūtau pākahiko i roto i te raupapa e whakawhirinaki tika ana ki te awhe ngaohiko o te kaiwhakahaere, ko te whakatauranga iahiko o te kaiwhakahaere e whakatau ana i ngā whakaritenga iahiko BMS e tika ana. Mā tēnei whanaungatanga e whakaatu he aha te mea nui te mārama ki ngā tawhā kaiwhakahaere mō te hoahoa tika o te pūnaha EV.

Hei whakatau i ngā raruraru, ina whakaatu te pākahiko i te ngaohiko putanga engari kāore e taea te tīmata i te waka, ko ngā tawhā whakahaere o te kaiwhakahaere te wāhi tuatahi hei tirotiro. Me mahi tahi te Pūnaha Whakahaere Pūhiko me te kaiwhakahaere kia pono ai te mahi. I te whanaketanga o te hangarau EV, mā te mōhio ki tēnei whanaungatanga taketake ka āwhina i ngā rangatira me ngā tohunga hangarau ki te arotau i te mahi me te karo i ngā take hototahi noa.
