Active charge balance nzira yekuongorora

Iyo Automotive Systems Injiniya Dhipatimendi reMunich-based Infineon Technologies nguva pfupi yadarika yakagamuchira basa rekugadzira mota dzemagetsi. Motokari yemagetsi imotokari inotyairika, iyo yakakosha zvikuru pakuratidza kushanda kwemagetsi emotokari dzemagetsi dzakasanganiswa. Iyo mota ichave inofambiswa nehombe lithium bhatiri pack, uye vanogadzira vanonzwisisa kuti bhatiri rakaenzana rinodikanwa. Muchiitiko ichi, iwe unofanirwa kusarudza otomatiki simba rekufambisa pakati pemabhatiri pachinzvimbo chechinyakare chakareruka chaja kuenzanisa nzira. Iyo yega-charge balancing system yavakagadzira inogona kupa mabasa epamusoro nemutengo wakafanana neurongwa hwekusungirwa.

Battery chimiro

Ni-Cd uye Ni-MH mabhatiri akatonga musika webhatiri kwemakore mazhinji. Kunyangwe iyo 18650 lithium bhatiri chiri chigadzirwa chichangobva kupinda mumusika, chikamu chayo chemusika chiri kusimuka nekukurumidza nekuda kwekuvandudzwa kwakanyanya mukuita. Iyo yekuchengetera mabhatiri e lithium inoshamisa, asi kunyangwe zvakadaro, kugona kwebhatiri rimwe chete hakuna kukwana voltage kana ikozvino kuzadzisa zvinodiwa zveinjini yakasanganiswa. Mabhatiri akawanda anogona kubatanidzwa mukuenderana kuwedzera bhatiri magetsi ekupa ikozvino, uye akawanda mabhatiri anogona kubatanidzwa munhevedzano kuwedzera bhatiri magetsi ekupa voltage.

Vanounganidza bhatiri vanowanzo shandisa acronyms kutsanangura zvigadzirwa zvebhatiri, se3P50S, zvinoreva kuti bhatiri paki inoumbwa nemabhatiri matatu akafanana uye makumi mashanu mabhatiri akateedzana.

Iyo modular chimiro chakanakira kubata mabhatiri, kusanganisira akawanda akatevedzana ebhatiri maseru. Semuenzaniso, mune 3P12S bhatiri array, masero gumi nemaviri ebhatiri akabatanidzwa munhevedzano kuti aite bhuroka. Aya mabhatiri anogona kudzorwa uye kuenzaniswa nemagetsi edunhu akatarisana neiyo microcontroller.

Iyo inobuda voltage yebhatiri module inoenderana nehuwandu hwemabhatiri akabatana munhevedzano uye voltage yebhatiri rega rega. Mhepo yebhatiri yelithium inowanzova pakati pe3.3V ne3.6V, saka voltage yebhatiri module inenge iri pakati pe30V ne45V.

Simba rehybrid rinofambiswa ne450 volt DC magetsi. Kuti utsivise shanduko yebhatiri voltage nehurumende yekuchaja, zvakakodzera kubatanidza DC-DC inoshandura pakati pebhatiri pack neinjini. Iyo inoshandura zvakare inodzikamisa yazvino kubuda kwebhatiri pack.

Kuti uve nechokwadi chekuti DC-DC inoshandura inoshanda mune yakanakisa mamiriro, bhatiri voltage inofanirwa kunge iri pakati pe150V ~ 300V. Naizvozvo, 5 kusvika 8 bhatiri module inodiwa munhevedzano.

kudiwa kwekuenzanisa

Apo mhepo inodarika muganhu unobvumirwa, lithiamu bhatiri inokuvadza nyore nyore (sezvinoratidzwa mumufananidzo 2). Kana magetsi achidarika epamusoro neakadzika miganhu (2V yenano-phosphate lithium mabhatiri, 3.6V yekumusoro muganhu), bhatiri rinogona kukuvara zvisingagadzirisiki. Nekuda kweizvozvo, zvirinani kuzviburitsa kwebhatiri kunowedzera. Iyo inobuda voltage yebhatiri yakagadzikana munzvimbo yakakura yekuchaja (SOC) renji, uye panenge pasina njodzi yevoltage inodarika mwero mukati menzvimbo yakachengeteka. Asi pamativi ese ari maviri enzvimbo yakachengeteka, iyo yekuchaja curve ine kukwidza. Naizvozvo, seyero yekudzivirira, zvinodikanwa kunyatso tarisisa voltage.

Kana iyo voltage ichisvika pamutengo wakakosha, kuburitsa kana kubhadharisa maitiro kunofanirwa kumiswa nekukasira. Nekubatsirwa kwechitsiko chakasimba chekuenzanisa, mhepo yebhatiri yakakodzera inogona kudzorerwa kune yakachengeteka. Asi kuti uite izvi, dunhu rinofanira kukwanisa kufambisa simba pakati pemaseru kana voltage yeimwe sero inotanga kusiyanisa kubva kune voltage yemamwe maseru.

charge balance nzira

1. Chinyakare chinosungirwa: Mune yakajairwa bhatiri yekubata system, bhatiri rega rega rakabatana kune rekuremedza resistor kuburikidza nekuchinja. Iyi dunhu rekumanikidzwa rinogona kuburitsa mabhatiri akasarudzwa ega. Nekudaro, nzira iyi inogona kungochajiswa kudzvanya kukwira kwevoltage yebhatiri rakasimba. Kuti udzikise mashandisirwo emagetsi, dunhu rinowanzo bvumidza kuburitswa pane diki ikozvino ye100 mA, izvo zvinoguma muyero yekuchaja inotora maawa akati wandei.

2. Automatic balancing method: Kune dzakawanda otomatiki kuenzanisa nzira dzine chokuita nezvinhu, zvose zvinoda simba rekuchengetedza simba kutakura simba. Kana iyo capacitor inoshandiswa sechinhu chekuchengetedza, kuibatanidza kune chero bhatiri inoda huwandu hwakawanda hwekuchinja. Imwe nzira inobudirira ndeyekuchengetedza simba mune magnetic field. Chinhu chakakosha munharaunda ndeye transformer. Iyo prototype yakagadzirwa neInfineon budiriro timu mukubatana neVogt Electronic Components Co., Ltd. Mabasa ayo ndeaya anotevera:

A. Kuendesa simba pakati pemabhatiri

Batanidza voltage yemasero akawanda kune base voltage yeADC yekupinda

Dunhu rinoshandisa musimboti we reverse scan transformer. Transformer iyi inogona kuchengeta simba mundima yemagineti.
