Ukubaluleka kolawulo lwebhetri kuye kwabonakala. Iimveliso ezininzi ngakumbi zisiya kwicala eliphathwayo, zisebenzisa ukuzimela okungazange kubonwe ngaphambili. Phambi kweminyaka elishumi eyadlulayo, ifowuni engenantambo yaqala yanika inkululeko yokuhamba ekhaya.

Ngoku, iimveliso eziphathwayo ezinokutshajwa kwakhona zenza abantu bahlale benxibelelana neentsapho zabo ngelixa abantu behamba. Iimveliso ezininzi ngakumbi zisebenzisa iibhetri ezinokutshajwa, kwaye ngokuncipha komthamo wemveliso, ubunzima bezi mveliso buhlala buphucuka. Ibhetri yokutshaja ngokwayo iyatshintsha, abavelisi beebhetri bazama ukuqalisa iimveliso ezintsha ezihambelana nokutshintsha ngokukhawuleza kweemarike.

Umbane webhetri uyongezwa, ukucaciswa kwemilo kuyatshintshwa, kwaye ukuxinana kwamandla nako kunyuka. Ukuqonda kwabathengi ngebhetri kunzulu kakhulu, kufuneka babe bhetyebhetye ngakumbi, iiyure ezinde zokusebenza, iindleko eziphantsi kunye nokhuseleko oluphezulu. I-Microchip isebenze nzima ukwenza lula uyilo lwenkqubo kunye ne-PIC microcontrollers iminyaka emininzi.

Okwangoku, i-Microchip isebenzisa le teknoloji kumgca wemveliso yokulawula ibhetri ukwenza lula nokulawula ngcono inkqubo yokutshaja. Indlela yokuqala, inkqubo yolawulo lwebhetri eqhelekileyo yahlulwe yaba ziimodyuli ezine zokutshaja, ukhuseleko, umlinganiselo wombane, kunye nokhuseleko: 1. Ibhetri esekwe kwibhetri yesibini yahlukile kwipakethi yebhetri, kwaye ibhetri yesibini itshajiswe emva kokusetyenziswa.

Endaweni yokuba ilahlwe okwebhetri. Iindidi kunye nee-algorithms zokutshaja zesekethe yokutshaja ziyahlukahlukana, kwaye zihlawuliswa ngokufanelekileyo kwiintlobo ezithile zeekhemikhali zeebhetri. Indawo yetshaja nayo kufuneka ikhethwe ngokufanelekileyo.

Itshaja yiyunithi ezimele yodwa: yintlawulo ethe ngqo yesiguquli okanye ngesiguquli; itshaja idityaniswe ngaphakathi kwisistim okanye ngaphakathi kwipakethi yebhetri; ezinye izinto ezibalulekileyo eziqwalaselwayo ziquka ixesha lokutshaja, uluhlu lobushushu kunye neemfuno zengxolo. I-Microchip ibonelela ngeemveliso ezahlukeneyo zolawulo lokutshaja kwiitshaja ezinomgca omnye okanye ezimbini ze-lithium ion / ipolima yebhetri. Ingxolo ephumayo yetshaja yomgca iphantsi, ebaluleke kakhulu kwabo bathumela kwaye bafumane ilizwi kunye nedatha.

Yenzelwe ukusebenza kakuhle, i-PS200 yokutshintsha imowudi yokutshaja ukuya kuthi ga kwi-1MHz. Iquka i-algorithm yokutshaja iibhetri ze-lithium ion, iibhetri ze-nickel kunye neebhetri ze-lead-acid. Ekubeni uyilo lwetshaja yokutshintsha lunzima ngakumbi, iMicrochip ibonelele ngezixhobo zesoftware ukukhokela abaqulunqi ukuba benze uqwalaselo lwe-IC kunye nemizobo yesekethe.

Kwishishini eliqhelekileyo elinikezelwe kwimveliso yeshaja, esinye isisombululo kukusebenzisa imitha yombane i-IC kunye nomlawuli wokutshaja.
