Ka dib ku dhawaad 10 sano oo horumarin ah, gawaarida tamarta cusub ee tamarta ayaa sameeyay xoogaa uruurin tignoolajiyadeed.Waxaa jira aqoon badan oo ku saabsan naqshadeynta qaybaha gawaarida korontada iyo xulashada iyo isku-dhafka qaybaha.Waxaa ka mid ah, naqshadeynta caabbinta precharge ee wareegga precharge waxay u baahan tahay inay tixgeliso shuruudo badan iyo xaalado shaqo.Xulashada iska caabiyaha precharge waxay go'aaminaysaa xawaaraha wakhtiga baabuurka precharge, cabbirka booska uu ku jiroprecharge resistor, iyo badbaadada, isku halaynta, iyo xasiloonida korantada sare ee gaadhiga.
Precharge resistor waa iska caabin si tartiib tartiib ah u dalacaya capacitor-ka marxalada hore ee korontada sare ee gaariga.Haddii aanu jirin precharge resistor, dallacaadda xad-dhaafka ah ee hadda ayaa jebin doonta capacitor-ka.Koronto-sare ayaa si toos ah loogu dabaqaa capacitor-ka, taas oo u dhiganta wareeg gaaban oo degdeg ah.Xilliga xad-dhaafka ah ee wareegga gaaban wuxuu dhaawici doonaa qaybaha korantada ee korantada sare. Sidaa darteed, iska caabiyaha precharge waa in la tixgeliyaa marka la naqshadeynayo wareegga si loo hubiyo badbaadada wareegga.
Waxaa jira laba goobood ooprecharge resistorswaxaa loo isticmaalaa in wareegyada danab dhexdhexaad ah iyo sare ee baabuurta korontada, kuwaas oo motor controller precharge circuit iyo korantada sare dheeraad ah precharge circuit.Matoorka kontaroolaha waxaa ku jira capacitor weyn (inverter circuit), kaas oo u baahan in la sii dalacsiiyo si loo xakameeyo kapacitor-ka ku dallaca hadda.Qalabka korantada sare leh guud ahaan waxaa ka mid ah DCDC (DC Converter), OBC (charger-board), PDU (sanduuqa qaybinta korantada sare ee korontada), bamka saliidda, bamka biyaha, AC (compressor-hawo) iyo qaybo kale, waxaana sidoo kale jira qaybo kale. capacitors waaweyn gudaha qaybaha., markaa precharging ayaa loo baahan yahay.
Iska caabiyeyaasha prechargeR, wakhtiga precharge T, iyo loo baahan yahay capacitor precharge capacitor, wakhtiga precharge guud ahaan waa 3 ilaa 5 jeer RC, iyo wakhtiga precharge guud ahaan millise seconds.Sidaa darteed, dallacaadda hore ayaa loo dhammayn karaa si dhakhso ah mana saameyn doonto istaraatiijiyada kontoroolka awoodda-ku-ool ee baabuurka.Shuruudda lagu xukumayo in precharging la dhammeeyay iyo in kale waa haddii ay gaadho 90% danabka baytariga korantada (sida caadiga ah waa xaaladdu).Marka la dooranayo iska caabin precharge ah, shuruudaha soo socda waa in la tixgeliyo: danab batari korantada, contactor lagu qiimeeyay hadda, capacitor C qiimaha, heerkulka deegaanka ugu badnaan, kor u kaca heerkulka resistor, danab ka dib precharge, precharge time, insulating qiimaha caabbinta, tamarta garaaca wadnaha.Habka xisaabinta tamarta garaaca wadnaha waa kala badh sheyga labajibbaaran ee danabka garaaca wadnaha iyo awoodda dhibicda qiimaha C.Haddii ay tahay garaaca wadnaha oo joogto ah, markaa wadarta tamarta waa inay noqotaa wadarta tamarta dhammaan garaacyada.
