Iinkqubo zamandla ombane aphezulu zinokusebenza ngakumbi, zifuna umsinga omncinci wombane ofanayo, ngaloo ndlela kuncitshiswe ilahleko yamandla.
3. Ubomi bomjikelo
Ubomi bomjikelo bubhekisa kwinani lentlawulo kunye nemijikelo yokukhupha ibhetri enokuthi igqithe kuyo phambi kokuba umthamo wayo wehle kakhulu. Iibhetri ze-lithium ezifakwe kwi-Rack ngokuqhelekileyo zinobomi bomjikelezo we-2,000 ukuya kwi-5,000 imijikelezo, kuxhomekeke kubunzulu bokukhutshwa (DoD) kunye neemeko zokusebenza. Ubomi bomjikelo omde buthetha iindleko eziphantsi zokutshintshwa kunye nokusebenza okungcono kwexesha elide.
4. Ubunzulu bokukhutshwa (DoD)
Ubunzulu bokukhutshwa sisalathisi esichaza ukuba ungakanani umthamo webhetri onokusetyenziswa ngaphandle kokonakalisa ibhetri. Iibhetri ze-lithium ezifakwe kwiRack zihlala zine-DoD ye-80% ukuya kwi-90%, evumela abasebenzisi ukuba basebenzise amandla amaninzi agciniweyo. Oku kuluncedo kakhulu kwiiaplikeshini ezifuna ukukhwela ibhayisekile rhoqo, njengoko kukhulisa usetyenziso lwamandla akhoyo ebhetri.
5. Ukusebenza kakuhle
Ukusebenza kakuhle kwenkqubo yebhetri ye-lithium efakwe kwi-rack ngumlinganiselo wokuba angakanani amandla agcinwe ngexesha lokuhlawula kunye nokukhupha imijikelezo. Iibhetri ze-lithium ezikumgangatho ophezulu zihlala zihamba kakuhle ukuya nokubuya kwi-90% ukuya kwi-95%. Oku kuthetha ukuba kuphela inxalenye encinci yamandla elahlekileyo ngexesha lokuhlawula kunye nokukhupha, okwenza kube isisombululo sokugcina amandla eendleko.
6. Uluhlu lobushushu
Ubushushu bokusebenza yenye ingcaciso ebalulekileyo yeebhetri ze-lithium ezifakwe kwi-rack. Uninzi lweebhetri ze-lithium zenzelwe ukuba zisebenze ngokufanelekileyo phakathi komgangatho wokushisa we -20 ° C ukuya kuma-60 ° C (-4 ° F ukuya kwi-140 ° F). Ukugcina ibhetri ngaphakathi kolu luhlu lobushushu kubalulekile ekusebenzeni kakuhle kunye nokuphila ixesha elide. Ezinye iisistim eziphucukileyo zinokubandakanya iimpawu zolawulo lobushushu ukulawula ubushushu kunye nokwandisa ukhuseleko.
7. Ubunzima kunye nemilinganiselo
Ubunzima kunye nobukhulu beebhetri ze-lithium ezifakwe kwi-rack zibalulekile ingqalelo, ngakumbi xa ufaka kwindawo encinci. Ezi bhetri ziqhelekile ukuba khaphukhaphu kwaye zixinene kuneebhetri ze-asidi ekhokelayo, nto leyo ezenza kube lula ukuziphatha nokuzifaka. Iyunithi yebhetri ye-lithium eqhelekileyo efakwe kwi-rack inobunzima phakathi kwe-50 kunye ne-200 yeekhilogram (i-110 kunye ne-440 yeepounds), kuxhomekeke kumthamo kunye noyilo.
8. Iimpawu zoKhuseleko
Ukhuseleko lubalulekile kwiinkqubo zokugcina amandla. Iibhetri ze-lithium ezifakwe kwiRack zinemisebenzi emininzi yokhuseleko efana nokukhuselwa kwe-thermal runaway, ukukhuselwa kwe-overcharge, kunye nokukhusela isiphaluka esifutshane.
