Iiprojekthi ezininzi ze-EV tshaja zikhawulelwe ngoku kwisiza kwaye azikwazi ukunika amandla kwiimfumba zokutshaja ezaneleyo.
Siye sasungula isicwangciso soku emva kophando nophuhliso.
“000” yeyona mfumba iphambili yemfumba yeqela kwaye inomsebenzi wokulawula iqela leemfumba lendawo. Ezinye iimfumba ziimfumba ezincedisayo. Ingqumba ephambili ijonga ukuba i-current idlula ixabiso elilinganiselweyo (50A), kwaye ingqumba ephambili ilawula umsinga wokutshaja weemfumba zamakhoboka ezilandelayo.
Nangona kunjalo, ngokomgangatho, ubuncinci bexesha elisebenzayo lemfumba nganye kufuneka ilawulwe ngaphezu kwe-6A, ngoko ke ubuninzi be-layout yi-8 piles.
I-485 interface A kwi-PCB nganye iqhagamshelwe kumgca oyintloko we-A, kwaye u-B uqhagamshelwe kumgca ongundoqo we-B.
Ukuze ugweme ukuphazamiseka kwesignali, i-resistor ye-120 ohm idibaniswe ngokuhambelana kwi-interface ye-485 yemfumba ephambili kunye neyona mfumba ikude. Imfumba ephambili idityaniswe kwindandatho yamagnetic ye-CT ukuze ibone umgca ophambili wangoku, kwaye kwangaxeshanye usasaze i-current kwi-pile nganye ngokwexesha elifunyenweyo lazo zonke iimfumba.
Cwangcisa imfumba ephambili kunye nenqwaba yekhoboka ngokusebenzisa imiyalelo kwi-APP, kwaye usete umda ovumelekileyo ngoku.
