1. Kugona (chikamu: Ah)
Iyi ndiyo parameter iyo munhu wese anonyanya kunetseka nayo. Kuwanda kwebhatiri ndeimwe yeakakosha maratidziro ekuita kuyera mashandiro ebhatiri, izvo zvinoratidza kuti pasi pemamwe mamiriro (discharge rate, tembiricha, termination voltage, etc.) bhatiri rinoburitsa huwandu hwemagetsi (iripo JS-150D discharge test) , ndiko kuti, kukwanisa kwebhatiri, kazhinji mu amperage - maawa sechikwata (kupfupisa, kunoratidzwa mu AH, 1A-h = 3600C). Semuenzaniso, kana bhatiri iri 48V200ah, zvinoreva kuti bhatiri rinogona kuchengeta 48V*200ah=9.6KWh, kureva, 9.6 kilowatts emagetsi. Battery simba rakakamurwa kuita chaiko kugona, theoretical kugona uye yakayerwa huwandu zvinoenderana neakasiyana mamiriro.
Kugona chaikoinoreva huwandu hwemagetsi bhatiri rinogona kupa pasi pehumwe hutongi hwekubuda (imwe sedimentation level, imwe yazvino density uye imwe yekumisa voltage). Hunhu chaihwo hahuna kuenzana nechiyero chakayerwa, icho chine hukama zvakananga nekushisa, humidity, kuchaja uye chiyero chekuburitsa. Kazhinji, huwandu chaihwo hudiki pane hwakayerwa huwandu, dzimwe nguva hudiki zvakanyanya pane hwakayerwa huwandu.
Theoretical kugonazvinoreva huwandu hwemagetsi anopiwa nezvinhu zvese zvinoshanda zvinotora chikamu mukuita kwebhatiri. Ndiko kuti, kugona mune yakanyanya kunaka mamiriro.
Rated capacityinoreva zita rezita rinoratidzwa pamotokari kana midziyo yemagetsi muyakayerwa mamiriro ekushanda anogona kuramba achishanda kwenguva yakareba. Kazhinji zvinoreva simba rinooneka rema transformer, simba rinoshanda remotor, uye rinooneka kana reactive simba rechikamu-chinodzora michina, muVA, kVA, MVA. Mukushandisa, iyo geometry yepole plate, kuguma kwevoltage, tembiricha, uye chiyero chekuburitsa zvese zvine chekuita pahuwandu hwebhatiri. Semuenzaniso, munguva yechando kuchamhembe, kana foni inoshandiswa kunze, simba rebheteri rinodonha nokukurumidza.
2. Simba Density (chikamu: Wh/kg kana Wh/L)
Kuwanda kwesimba, bhatiri simba density, kune yakapihwa electrochemical simba rekuchengetedza mudziyo, chiyero chesimba rinogona kubhadhariswa kuhuwandu kana vhoriyamu yepakati yekuchengetera. Iyo yekutanga inonzi "mass energy density", iyo yekupedzisira inonzi "volumetric energy density", iyo unit inoteerana watt-awa/kg Wh/kg, watt-awa/lita Wh/L. Simba riri pano, ndiro rataurwa pamusoro apa (Ah) uye yekushanda voltage (V) yechinhu chakakosha. Kana zvasvika kumashandisirwo, iyo metric yesimba density inodzidzisa kupfuura kugona.
Zvichienderana neiyo iripo lithium-ion bhatiri tekinoroji, iyo simba density level inogona kuwanikwa ingangoita 100 ~ 200Wh/kg, iyo ichiri yakaderera uye yave bhodhoro re lithium-ion bhatiri application mune dzakawanda nguva. Dambudziko iri rinoitikawo mumunda wemotokari dzemagetsi, muhuwandu uye uremu huri pasi pemiganhu yakasimba, simba remagetsi rebhatiri rinotarisa huwandu hwekutyaira kwemotokari dzemagetsi, saka "mileage kunetseka" iyi izwi rakasiyana. Kana motokari yemagetsi inotyaira imwe chete ichisvika makiromita 500 (kuenzaniswa nemotokari yemafuta emazuva ese), simba rebhatiri rinofanirwa kunge riri 300Wh/kg kana kudarika.
Kuwedzera kwesimba remagetsi emabhatiri e-lithium-ion inzira inononoka, yakaderera zvakanyanya kupfuura Mutemo waMoore muindasitiri yedunhu yakabatanidzwa, iyo inogadzira mutsauko pakati pekuvandudzwa kwekuita kwezvigadzirwa zvemagetsi uye simba rekuwedzera kwesimba remabhatiri rinoramba richiwedzera nekufamba kwenguva. .
