Nekufambira mberi kwetekinoroji munguva pfupi yapfuura, mainjiniya aifanira kuwana nzira yakanakisisa yekupa simba kuzvinhu zvavo zvitsva. Marobhoti emagetsi, mabhasikoro emagetsi, masikuta, macleaners, uye zvishandiso zve smartscooter zvese zvinoda simba rinoshanda. Mushure memakore ekutsvagisa nekuyedza nekukanganisa, mainjiniya akasarudza kuti imwe mhando yesystem yebhatiri inosiyana nedzimwe: system yekutarisira bhatiri yakangwara (BMS). Bhatiri reBMS rakajairika rine lithium anode uye rine nhanho yehungwaru yakafanana nekombuta kana robhoti. Sisitimu yeBMS inopindura mibvunzo yakaita sekuti, "Robhoti remagetsi ringaziva sei kuti yave nguva yekuzvichaja?" Chinosiyanisa module yeBMS yakangwara nebhatiri yakajairika ndechekuti inogona kuongorora huwandu hwayo hwesimba uye kutaurirana nezvimwe zvishandiso zvakangwara.

Chii chinonzi Smart BMS?

Usati watsanangura BMS yakangwara, zvakakosha kunzwisisa kuti BMS yakajairwa chii. Muchidimbu, sisitimu yenguva dzose yekutonga bhatiri re lithium inobatsira kuchengetedza nekugadzirisa bhatiri rinochajwazve. Rimwe basa reBMS nderekuverenga data rechipiri wozorizivisa mushure mezvo. Saka, BMS yakangwara yakasiyana sei nesisitimu yekutonga bhatiri inoshanda? Sisitimu yakangwara ine kugona kutaurirana nechaja yakangwara yozozvichajazve yoga. Zvinhu zviri kuseri kweBMS zvinobatsira kuwedzera hupenyu hwebhatiri uye kuwedzera mashandiro aro. Kungofanana nemudziyo wenguva dzose, BMS yakangwara inovimba zvakanyanya nesisitimu yakangwara pachayo kuti irambe ichishanda. Kuti iwane mashandiro akanyanya, zvikamu zvese zvinofanirwa kushanda pamwe chete.

Masisitimu ekugadzirisa mabhatiri pakutanga (uye achiri kushandiswa) mumalaptop, makamera evhidhiyo, maDVD player anotakurika, nezvimwe zvigadzirwa zvemumba zvakafanana. Mushure mekuwedzera kwekushandiswa kwemasisitimu aya, mainjiniya aida kuyedza miganhu yawo. Saka, vakatanga kuisa masisitimu emagetsi eBMS mumamota emagetsi, maturusi emagetsi, uye kunyange marobhoti.

Zvigadziko zveHardware neCommunication

Simba rinoita kuti BMS ishandiso yakagadziridzwa. Iyi simbi inobvumira bhatiri kuti rikwanise kutaurirana nezvimwe zvikamu zveBMS, zvakaita sechaja. Uyezve, mugadziri anowedzera imwe yemasoketi ekutaurirana anotevera: RS232, UART, RS485, CANBus, kana SMBus.

Heino kutarisa apo imwe neimwe yeaya masokisi ekutaurirana anotanga kushanda:

• Bhatiri reLithiumneRS232 BMS inowanzo shandiswa paUPS muzviteshi zvefoni.
• Bhatiri reLithium rine RS485 BMS rinowanzo shandiswa pazviteshi zvemagetsi ezuva.
• Bhatiri reLithium rine CANBus BMS rinowanzo shandiswa pamascooter emagetsi, uye pamabhasikoro emagetsi.
• Bhatiri reLtihium rine UART BMS rinoshandiswa zvakanyanya pamabhasikoro emagetsi, uye

Uye Tarisa Zvakadzama Bhatiri reBhasikoro reMagetsi reLithium rine UART BMS

BMS yeUART yakajairika ine masisitimu maviri ekutaurirana:

• Shanduro: RX, TX, GND
• Shanduro yechipiri: Vcc, RX, TX, GND

Ndeupi Musiyano Pakati Pemasisitimu Aviri Nezvikamu Zvawo?

BMS controls uye masisitimu zvinokwanisa kutamisa data kuburikidza neTX neRX. TX inotumira data, ukuwo RX ichigamuchira data. Zvakakoshawo kuti lithium ion BMS ive neGND (ground). Musiyano uripo pakati peGND mushanduro yekutanga neyechipiri ndewekuti mushanduro yechipiri, GND inovandudzwa. Shanduro yechipiri ndiyo sarudzo yakanakisa kana uchironga kuwedzera optical kana digital isolator. Kuti uwedzere chimwe chezviviri izvi, uchashandisa Vcc, inova chikamu cheUART BMS' version yechipiri communication system.

Kuti tikubatsirei kuona zvinhu zveUART BMS zvine VCC, RX, TX, GND, taisa mufananidzo uri pazasi.

Chinosiyanisa iyi li-ion battery management system kubva kune zvimwe ndechekuti unogona kuitarisa panguva chaiyo. Kunyanya, unogona kuwana mamiriro ekuchaja (SOC) uye mamiriro ehutano (SOH). Zvisinei, hauzowani data iri nekungotarisa bhatiri. Kuti ubvise data, unofanirwa kuribatanidza nekombuta kana controller yakasarudzika.

Heino muenzaniso webhatiri reHailong rine UART BMS. Sezvauri kuona, sisitimu yekutaurirana yakafukidzwa nechinhu chekudzivirira bhatiri chekunze kuti ive nechokwadi chekuti rakachengeteka uye rinoshandisika. Nerubatsiro rwesoftware yekutarisa bhatiri, kuongorora zviyero zvebhatiri munguva chaiyo kuri nyore. Unogona kushandisa waya yeUSB2UART kubatanidza bhatiri pakombuta yako. Kana yangobatanidzwa, vhura software yekutarisa BMS pakombuta yako kuti uone zvakatsanangurwa. Pano uchaona ruzivo rwakakosha senge kugona kwebhatiri, tembiricha, voltage yemasero, nezvimwewo.

Sarudza BMS Yakakodzera Yechishandiso Chako

Ipa nhamba yebhatiriuye vagadziri veBMS, zvakakosha kuwana avo vanopa mabhatiri emhando yepamusoro ane maturusi ekutarisa. Pasinei nekuti purojekiti yako inoda chii, tinofara kukurukura nezvemasevhisi edu uye mabhatiri atinawo. Kana uine mibvunzo maererano nemasisitimu ekugadzirisa mabhatiri akangwara, usazeza kutibata. Tichakupa iwe chete sisitimu yakanakisa yeBMS yakangwara uye takagadzirira kukubatsira kuwana yakakodzera zvaunoda.
