I runga i ngā whanaketanga hangarau hou, me kimi e ngā kaihangarau he huarahi pai hei whakakaha i ā rātou mahi auaha. Me whai pūtake hiko whai hua ngā karetao whakahaere aunoa, ngā pahikara hiko, ngā kuta, ngā kaihoroi, me ngā taputapu kuta atamai. Whai muri i ngā tau o te rangahau me te whakamātautau me ngā hapa, i whakatau ngā kaihangarau he momo pūnaha pākahiko kotahi te mea e tu ke ana i ētahi atu: ko te pūnaha whakahaere pākahiko atamai (BMS). He anode lithium te pākahiko BMS paerewa, ā, he rite te taumata o te mohio ki te rorohiko, ki te karetao rānei. Ka whakautua e te pūnaha BMS ngā pātai pēnei i te, "Me pēhea te mōhio o te karetao whakahaere kua tae ki te wā ki te whakahou i a ia anō?" Ko te mea e wehewehe ana i te wae BMS atamai i te pākahiko paerewa ko tana taea te aromatawai i tōna taumata mana me te kōrero ki ētahi atu taputapu atamai.

He aha te BMS Atamai?

I mua i te tautuhi i tētahi BMS atamai, he mea nui kia mārama he aha te BMS paerewa. I roto i te poto, ka āwhina te pūnaha whakahaere pākahiko lithium noa ki te tiaki me te whakahaere i tētahi pākahiko ka taea te whakahou. Ko tētahi atu mahi a te BMS ko te tatau i ngā raraunga tuarua, kātahi ka ripoata i muri mai. Nō reira, he aha te rerekētanga o tētahi BMS atamai mai i tētahi pūnaha whakahaere pākahiko noa? Ka taea e te pūnaha atamai te kōrero ki te rihi atamai, kātahi ka utu anō i a ia anō. Ko ngā mahi i muri i te BMS ka āwhina ki te whakaroa i te ora o te pākahiko me te whakanui ake i tana mahi. Pērā i tētahi taputapu noa, ka whakawhirinaki nui te BMS atamai ki te pūnaha atamai tonu kia mau tonu tana mahi. Hei whakatutuki i te mahi tino pai, me mahi tahi ngā wāhanga katoa i roto i te tukutahi.

I te tīmatanga, i whakamahia ngā pūnaha whakahaere pākahiko (ā, kei te whakamahia tonutia) i roto i ngā pona, i ngā kāmera ataata, i ngā kaitākaro DVD kawe, me ngā hua whare rite tonu. Whai muri i te pikinga ake o te whakamahinga o ēnei pūnaha, i hiahia ngā kaihangarau ki te whakamātau i ō rātou rohe. Nō reira, ka tīmata rātou ki te whakamahi i ngā pūnaha pākahiko hiko BMS ki roto i ngā motopaika hiko, ngā taputapu hiko, tae atu ki ngā karetao.

Ngā Pūoko Taputapu me ngā Hononga Whakawhitiwhiti Kōrero

Ko te pūmārō whakapai ake te mea e akiaki ana i te BMS. Mā tēnei pūmārō ka taea e te pākahiko te kōrero ki ētahi atu wāhanga o te BMS, pērā i te rihi. Hei tāpiri, ka tāpirihia e te kaihanga tētahi o ngā tūhono kōrero e whai ake nei: RS232, UART, RS485, CANBus, SMBus rānei.

Anei tētahi tirohanga mō te wā e whakamahia ai ia o ēnei pūtukatuka whakawhitiwhiti kōrero:

• Pūhiko lithiumme te RS232, ka whakamahia te BMS i runga i te UPS i ngā teihana waea.
• Ko te pākahiko lithium me te RS485 BMS e whakamahia ana i ngā teihana hiko o te rā.
• Ko te pākahiko lithium me te CANBus BMS e whakamahia ana i runga i ngā kuta hiko me ngā pahikara hiko.
• He whānuitia te whakamahinga o te pākahiko Ltihium me te UART BMS i runga i ngā pahikara hiko, ā,

Me te Tirohanga Hōhonu ki te Pūhiko Pahikara Hiko Lithium me te UART BMS

E rua ngā pūnaha whakawhitiwhiti kōrero a te UART BMS noa:

• Putanga: RX, TX, GND
• Putanga 2: Vcc, RX, TX, GND

He aha te rerekētanga i waenganui i ngā pūnaha e rua me ō rāua wāhanga?

Ka taea e ngā mana whakahaere me ngā pūnaha BMS te whakawhiti raraunga mā TX me RX. Ka tukuna e TX ngā raraunga, ko RX ia ka whiwhi i ngā raraunga. He mea nui anō hoki kia whai GND (whenua) te BMS lithium ion. Ko te rerekētanga i waenga i te GND i te putanga tuatahi me te tuarua ko te mea kua whakahoutia te GND i te putanga tuarua. Ko te putanga tuarua te kōwhiringa pai rawa atu mēnā kei te whakaaro koe ki te tāpiri i tētahi wehewehe whatu, mamati rānei. Hei tāpiri i tētahi o ngā mea e rua, me whakamahi koe i te Vcc, he wāhanga noa iho tēnei o te pūnaha whakawhitiwhiti putanga tuarua o te UART BMS.

Hei āwhina i a koe ki te tiro i ngā wāhanga ā-tinana o tētahi UART BMS me VCC, RX, TX, GND, kua tāpirihia e mātou te whakaaturanga whakairoiro i raro nei.

Ko te mea e wehewehe ana i tēnei pūnaha whakahaere pākahiko lithium i ētahi atu, ka taea e koe te aroturuki i te wā tonu. Ina koa, ka taea e koe te kimi i te āhua o te utu (SOC) me te āhua o te hauora (SOH). Heoi, kāore e kitea e koe ēnei raraunga mā te titiro noa ki te pākahiko. Hei tango i ngā raraunga, me hono atu koe ki tētahi rorohiko motuhake, ki tētahi kaiwhakahaere rānei.

Anei tētahi tauira o te pākahiko Hailong me te UART BMS. E kite ana koe, kua hipokina te pūnaha whakawhitiwhiti kōrero e tētahi pare pākahiko o waho hei whakarite i te haumaru me te whakamahinga. Mā te āwhina o te pūmanawa aroturuki pākahiko, he tino māmā te arotake i ngā inenga o te pākahiko i te wā tonu. Ka taea e koe te whakamahi i tētahi waea USB2UART hei hono i te pākahiko ki tō rorohiko. Kia honoa, whakatuwheratia te pūmanawa aroturuki BMS i tō rorohiko kia kite i ngā taipitopito. I konei ka kite koe i ngā mōhiohio nui pēnei i te kaha o te pākahiko, te pāmahana, te ngaohiko pūtau, me ētahi atu.
