Kutheni iibhetri zeemoto zombane zingabonisi ngokuchanekileyo ukuba zishiye kangakanani?

Ngoko, emva kombuzo wokuqala, kutheni izithuthi zombane (kunye neebhetri ezikhokelayo) zibonakala zingachanekanga? Oku kungenxa yokuba amandla ezithuthi zombane (ngokuqhelekileyo zibizwa ngokuba yi-SOC, okanye imeko yentlawulo) kunzima ukulinganisa kunamandla eefowuni eziphathwayo.

Kukho izizathu ezininzi zokuba kutheni iimoto zombane zinzima kakhulu ukuqikelela kuneefowuni eziphathwayo. Nanga amanye amanqaku anzulu:

Iindlela ezixhaphakileyo zoqikelelo lwe-SOC:

Masiqale ngento esiyazi ngcono: iGPS. Ngoku, indawo yeGPS esekwe kwiselula ichanekile kulandelelwano lweemitha. Ngokubhekiselele kwimijukujelwa, ukuma okunjalo akwanelanga. Zimbini izinto ezingekhoyo: ukuchaneka kunye nexesha lokwenyani (okt, inani lemizuzwana yokufunyanwa ngempumelelo). Ngoko umjukujelwa unenye inkqubo yembuyekezo: igyroscope.

I-Gyroscopes iphelele ngokupheleleyo kwi-satellite GPS positioning-zichanekile (ubuncinci kwi-millimeter scale) kunye nexesha langempela, kodwa ingxaki kukuba iimpazamo ziqokelele. Umzekelo, ukuba uvale amehlo umntu kwaye umcele ukuba ahambe ngomgca othe tye, awukwazi ukubona amashumi eemitha, kodwa unokukwazi ukuhamba iikhilomitha ezininzi kwaye ujike i-180 degrees.

Ngaba ikho indlela yokudibanisa ulwazi phakathi kwe-GPS kunye ne-gyroscope ukuze bancedisane ukuze bafumane eyona ndawo ichanekileyo? Impendulo nguewe, ukuhlunga kweKalman kulungile, yiloo nto.

Ingaba le nto inento yokwenza ntoni noqikelelo lwebhetri yeSOC? Kukho iindlela ezimbini eziqhelekileyo ezisetyenziswayo zokulinganisa iSOC:

Indlela yokuqala yindlela yombane wesekethe evulekileyo, elinganisa imeko yebhetri ngokusekelwe kumbane ovulekileyo wesekethe yebhetri. Oku kulula ukukuqonda, kodwa amandla ombane aphezulu ebhetri, amandla ebhetri aphantsi, amandla kunye nombane ombane ziyahambelana. Le ndlela ifana nokubeka i-GPS ye-satellite, akukho mpazamo yokuqokelela (kuba isekelwe kwiimeko), kodwa ukuchaneka kuphantsi (ngenxa yezinto ezahlukeneyo, impendulo yangaphambili ichazwe ngoku).

Uhlobo lwesibini lubizwa ngokuba yi-ampere hour integrator, elinganisa imeko yebhetri ngokudibanisa i-voltage (flow) yebhetri. Ngokomzekelo, ukuba uhlawula ibhetri ye-100-kilowatt, kwaye ixesha ngalinye ulinganisa okwangoku kwaye ukhulise ukuya kuma-degrees angama-50, amandla asele aya kuba ngama-50 degrees. Le ndlela inokuthelekiswa ne-gyroscopes echanekileyo (ukuchaneka kokulinganisa ngokukhawuleza kungaphantsi kwe-1%, i-0.1% indleko yokulinganisa iphantsi kwaye ixhaphake), kodwa impazamo eqokelelweyo inkulu. Ukongeza, nokuba i-ammeter luphawu lothixo kwaye ichanekile ngokupheleleyo, indlela edibeneyo kunye nendlela yombane ovulekileyo wesekethe ayinakwahlulwa xa kusetyenziswa iammeter. Ngoba? Ngenxa yokuba indalo yebhetri ngokwayo iya kutshintsha.

Ngokwemfundo, mhlawumbi ezinye iinkampani zeemoto eziphambili zidibanisa amandla ombane wesekethe evulekileyo kunye nodibaniso lweyure ye-ampere kunye ne-algorithm yokucoca i-Kalman ukufumana uqikelelo oluchanekileyo lwe-SOC, kodwa bahlala besenza iimpazamo kuba abayiqondi indlela yokwenza nzulu ukuvela kweebhetri. indalo.

Izithuthi zombane eziphuhliswe ziinkampani zemoto zasekhaya zihlala zisebenzisa indlela yombane wesekethe evulekileyo kunye nendlela yokudibanisa i-LAMV: le moto ilandelayo ishiya ixesha elaneleyo (umzekelo, imoto ivulwa ekuseni kuphela), kwaye indlela yombane wesekethe evulekileyo isetyenziswa qikelela ukuqala kwamandla, SOC_start uthe. Emva kokuba imoto iqalisiwe, imeko yebhetri iba ngumbhodamo, kwaye indlela yombane wesiphaluka evulekileyo ayisasebenzi. Emva koko, sebenzisa indlela yokudityaniswa ye-SOC_start-based amV ukuqikelela amandla ebhetri akhoyo.

Into ebalulekileyo eyenza i-SOC yezithuthi zombane zinzima ubunzima bokulinganisa iipakethi zebhetri ze-lithium. Okanye ngamanye amazwi, intsimi yophando enokwenza ukuba uqikelelo lwe-SOC lwesithuthi sombane lube luchaneka ngakumbi. Ubume beebhetri kunye neepakethi zebhetri lukhokelo oluphambili. Ukuphucula ukuchaneka kwesixhobo akusilo ulwalathiso lophando lwangoku oluchanekileyo ngokwaneleyo, kwaye kungakhathaliseki ukuba luchaneke kangakanani, alunamsebenzi.
