He aha te kaiwhakahaere motuka motuka
Ko te kaiwhakahaere mōtini motuka (MCU) te waeine hiko matua o ngā waka hiko hou, kei waenganui i te pākahiko hiko me te mōtini taraiwa. Ko tana mahi matua ko te huri i te iahiko tika ki te iahiko tauutuutu hei akiaki i te mōtini kia mahi, me te whakarite hihiri i te tere, te taipana me te ahunga o te mōtini kia rite ki ngā tohutohu taraiwa, kia taea ai te whakahaere i te tīmatanga, te whakatere, te aukati, te piki me ētahi atu āhua taraiwa o te waka.
Mahi matua

Ka tutukihia tēnei tukanga mā te inverter ā-roto, e whakamahi ana i ngā taputapu whakawhiti haurua-haurua pērā i ngā transistors, ngā IGBT rānei hei whakahaere i te auau me te kaha o te iahiko.
Youdaoplaceholder0 Whakahaere tere me te taipana : Whakaritehia te tere me te taipana o te motuka kia rite ki ngā whakaritenga taraiwa (pēnei i te tūranga taputapu, te whakateretere, te parai), me te whakatutuki i te whakahaere tika mā te hangarau PWM (pulse width modulation).
Youdaoplaceholder0 Tiaki pūnaha : Kei roto ko te tiaki taumaha rawa, te kimi hapa, te tiaki i te pūwāhi whakauru pākahiko me ētahi atu tikanga hei whakarite i te mahi haumaru o te pūnaha.
Youdaoplaceholder0 Whakaora pūngao : I te wā e pēhi ana i te pēhi, ka taea te huri i te pūngao nekeneke hei pūngao hiko mā te tukanga inverter hei utu i te pākahiko, ā, mā reira ka whakarei ake i te whānuitanga taraiwa.
Ngā wāhanga matua
Kōwae whakahaere Youdaoplaceholder0 : Ka tukatuka i ngā tohutohu taraiwa, ka whakaputa tohu PWM hei whakahaere i te inverter.
Kōwae hiko Youdaoplaceholder0 : Kei roto ko te IGBT me ētahi atu wāhanga whakawhiti hei whakatutuki i te huringa ngaohiko.
Pūoko Youdaoplaceholder0 : aroturuki i te tūnga o te motuka (pēnei i te pāmahana, te tere) ka tukuna atu ki te pūnaha whakahaere.
Pūnaha whakamarara wera Youdaoplaceholder0 : ka pupuri i te pāmahana mahi pumau i raro i ngā āhuatanga kawenga teitei.
Ka pā tika te mahi a te kaiwhakahaere motuka ki te wheako taraiwa me te whai huatanga o te pūngao o ngā waka hiko, ā, he pokapū matua e hono ana i te pākahiko hiko me te motuka taraiwa.
Ko te pūmana whakahaere motuka waka he wāhanga matua o ngā waka hiko, ā, ko ōna mahi matua ko:
Te whakahaere tere me te taipana
Ka whakatikatikaina te tere me te taipana o te motuka kia rite ki ngā tohutohu pēnei i te whakateretere me te parai. Ka whakatikatikaina te ngaohiko me te auau mā te hangarau PWM kia tutuki ai te whakatikatika tere tika, kia tutuki ai ngā whakaritenga taraiwa pēnei i te whakateretere, te parai, me te piki pari.
Te hurihanga pūngao me te taraiwa
Ka hurihia te iahiko tika mai i te pākahiko hiko hei iahiko whakawhiti hei taraiwa i te motuka, ā, ka whakatikatikaina te ahunga o te iahiko mā te inverter hei whakahaere i te hurihanga whakamua me te hurihanga whakamuri o te motuka. I te wā e pēhi ana, ka taea te huri i te kaha nekeneke hei kaha hiko, ka whakahokia ki te pākahiko.
Te tiakitanga pūnaha me te tautuhi
Aroturukihia ngā tawhā pēnei i te pāmahana me te ngaohiko o te motuka, tātarihia ngā hapa i te wā tonu (pēnei i te wera nui me te taumaha rawa), ā, me mahi i ngā mahi tiaki hei ārai i ngā kino. I taua wā anō, whakawhitiwhiti kōrero me te tohatoha raraunga ki ētahi atu pūnaha (pēnei i te BMS) mā te whatunga CAN.
Mana whakahaere urupare hihiri
Ka whakarerekētia motuhaketia te taipana me te rerenga aukume mā roto i ngā rauropi whakahaere whārite kia tere ai te urupare ki ngā tohutohu taraiwa. Ka maeneene te whakawhiti i te wā tīmatanga/mutu hei whakaiti i te kare o te ohorere.
Ko ngā hapa o te kaiwhakahaere motuka i roto i ngā waka hiko hou ka kitea ko te ngoikore o te mahi hiko, te uaua ki te tīmata, te pikinga o te whakapaunga hiko me ētahi atu raruraru. Me arotake whānuitia ngā take motuhake me te whakakotahitanga o ngā āhuatanga hapa.
Ngā āhuatanga hapa noa
Youdaoplaceholder0 Te hekenga o te mahi mana : Ka puhoi te urupare a te pētera whakatere, ka uaua ai te whakatere i te waka, ā, ka whakawhāitihia te tere mōrahi.
Youdaoplaceholder0 Tīmatanga rerekē : Tērā pea he uaua ki te tīmata, he maha ngā nganatanga kore angitu ki te tīmata, he oro/wiri rerekē rānei i te wā e tīmata ana.
Youdaoplaceholder0 Te pikinga o te whakapaunga pūngao : Mā te korenga o te pūmana ka heke pea te pai o te motuka me te whakapoto i te tawhiti o te waka.
Youdaoplaceholder0 Tohu rama hapa : E whakaatu ana te papatohu taputapu i te rama hapa pūnaha hiko, i te rama hapa pūnaha motuka rānei.
Tikanga tātaritanga hapa
Ngā whakamātautau taketake:
Tirohia mēnā he noa te ngaohiko hiko (whakamahia he mita maha hei ine mēnā he rerekē te ngaohiko 5V)
Tirohia mēnā kei te wera rawa te hiko i roto i te ara iahiko matua o te kaiwhakahaere (6 ngongo pana MOS)
Te kimi tohu Youdaoplaceholder0:
Inehia te huringa ngaohiko ina hurihia te kakau (awhe noa: 0-4.2VDC)
Tirohia mēnā kua wetekina, kua tawhito rānei ngā waea hono
Whakamātautau rerekē mō Youdaoplaceholder0:
Ki te ngaro te ātete o te kaata pana i muri i te momotu i ngā rārangi āwhata matotoru e toru o te motuka, tera pea he hapa o te kaiwhakahaere.
Whakamahia ngā taputapu ngaio (pēnei i te mita maha) hei whakamātautau i ngā tawhā pēnei i te diode me te whakahaere i te ngaohiko
Te Tātari i ngā Take o te Hapa
