Uhlobo kunye nokukhethwa kwamandla.

Okokuqala, kufuneka sibale umbane oqhubekayo webhetri ngokusekelwe kumandla ethu ombane (ukusebenzisa amandla, isantya somjikelezo jikelele sihambelana namandla okusebenza ahambelanayo). Umzekelo, ukuba i-motor iyaqhubeka nokusebenza kwi-20 (i-1000W motor kwi-48V), ibhetri kufuneka ikwazi ukubonelela nge-20 ngoku kwiqondo lokushisa eliphantsi kakhulu ixesha elide (nokuba ubushushu bangaphandle bungama-35 degrees ehlotyeni, ukushisa kwebhetri kufuneka kulawulwe kwii-50 degrees). Ukongezelela, ukuba i-48V yangoku yi-20A, i-overvoltage kufuneka iphindwe kabini (96V, njenge-ECpuLevel3), kwaye okwangoku kufuneka igcinwe malunga ne-50A. Ukuba uthanda ukusebenzisa i-over-voltage ixesha elide, nceda ukhethe ibhetri enokubonelela nge-50A ngokuqhubekayo (okanye ubeke ingqalelo ekunyukeni kweqondo lokushisa). Apha, ibhetri iyaqhubeka nokusebenza okwangoku endaweni yomthamo wokukhupha ibhetri yomenzi. Ukurhweba, ii-C ezimbalwa (okanye amakhulu e-amperes) ngumthamo wokukhupha ibhetri, kwaye kulo mandla akhoyo, ukufudumala kwebhetri kulula kakhulu, ukuba ukutshatyalaliswa kobushushu akulungile, ubomi bebhetri buya kuba bufutshane kakhulu. (Imeko yebhetri esetyenziswa kwiimoto zethu zombane zenziwe ngeebhetri, ezingenazo izikhewu, zitywinwe ngokuqinileyo, kungakhankanywa indlela yokwenza ukupholisa umoya ngenkani). Indawo yethu yoshishino inzima kakhulu. Ukukhutshwa kwangoku kwebhetri kufuneka kuncitshiswe. Uvavanyo lokukhutshwa kwebhetri umthamo wangoku usekwe kwiqondo lobushushu langoku lebhetri.

Umgaqo kuphela oxutyushwa apha kukunyuka kweqondo lokushisa kwebhetri ngexesha lokusetyenziswa (ubushushu obuphezulu lutshaba lobomi bebhetri ye-lithium). Ubushushu bebhetri kufuneka bugcinwe bungaphantsi kwama-50°C (kungcono ukuba buphakathi kwama-20 nama-30°C). Oku kuthetha ukuba ukuba ibhetri ye-lithium capacitive (ekhutshwe kwi-0.5C), ukukhutshwa okuqhubekayo okwangoku kwe-20A kufuneka kube mkhulu kunomthamo we-40ah (ngokuqinisekileyo, eyona nto ibalulekileyo kukujonga ukuchasana kwangaphakathi kwebhetri) . Ukuba luhlobo lwamandla e-lithium, kuyinto eqhelekileyo ukukhupha kwi-1C. Nkqu A123 ultra-ophantsi ukumelana yangaphakathi unikezelo lwamandla lithium ibhetri idla best ekhutshiweyo kwi 1C (ekukhethwa ukuba akukho ngaphezulu kwe 2C, 2C ukukhutshwa unokuqhuba kuphela isiqingatha seyure ukubiza, kwaye ixabiso ukusetyenziswa ayikho enkulu). Izinto ezifana nokukhethwa komthamo wemoto, ubungakanani bendawo yokugcina, uhlahlo lwabiwo-mali lweendleko zomntu, kunye nobukhulu boluhlu lwemisebenzi efunwa yimoto. (Umthamo webhetri ye-lithium esetyenziselwa unikezelo lwamandla ngokuqhelekileyo umncinci)
