1. Chiyambi cha batri ya lithiamu-ion
1.1 State of Charge (SOC)
State of charge angatanthauzidwe ngati mkhalidwe wa mphamvu yamagetsi yomwe ilipo mu batire, yomwe nthawi zambiri imawonetsedwa ngati kuchuluka.Chifukwa mphamvu yamagetsi yomwe ilipo imasiyanasiyana ndi kuthamangitsa ndi kutulutsa panopa, kutentha ndi kukalamba, kutanthauzira kwa dziko laling'ono kumagawidwa m'mitundu iwiri: Absolute State-Of-Charge (ASOC) ndi Relative State-Of-Charge (RSOC) .
Nthawi zambiri, kuchuluka kwa ndalama zolipirira ndi 0% - 100%, pomwe ndi 100% pomwe batire yayimitsidwa ndi 0% ikatulutsidwa.Mtheradi wa chiwongolero ndi mtengo wowerengera womwe umawerengedwa molingana ndi kuchuluka kwamphamvu komwe kudapangidwa batire ikapangidwa.Mtheradi wamtengo wapatali wa batri yatsopano yodzaza ndi 100%;Ngakhale batire lokalamba litakhala lokwanira, silingathe kufika 100% pansi pazifukwa zosiyanasiyana zolipiritsa ndi kutulutsa.
Chithunzi chotsatirachi chikuwonetsa mgwirizano pakati pa voteji ndi mphamvu ya batri pamitengo yosiyanasiyana yotulutsa.Kukwera kwa kuchuluka kwa kutulutsa, kumachepetsa mphamvu ya batri.Kutentha kukakhala kochepa, mphamvu ya batri idzachepanso.
Chithunzi 1. Ubale pakati pa voteji ndi mphamvu pansi pa mitundu yosiyanasiyana yotulutsa ndi kutentha
1.2 Max Kuthamangitsa Voltage
Kuthamanga kwambiri kwamagetsi kumakhudzana ndi kapangidwe kake ndi mawonekedwe a batri.Mphamvu yamagetsi ya batire ya lithiamu nthawi zambiri imakhala 4.2V ndi 4.35V, ndipo mphamvu zamagetsi za cathode ndi anode zidzasiyana.
1.3 Kulipiritsidwa kwathunthu
Pamene kusiyana pakati pa voteji ya batire ndi voteji yothamanga kwambiri ndi yosakwana 100mV ndipo mphamvu yotsatsira ikatsitsidwa kufika ku C/10, batireyo imatha kuonedwa ngati yodzaza kwathunthu.Kulipiritsa kwathunthu kumasiyana malinga ndi mawonekedwe a batri.
Chithunzi chomwe chili pansipa chikuwonetsa mawonekedwe amtundu wa batire ya lithiamu.Pamene mphamvu ya batri ili yofanana ndi mphamvu yowonjezera yowonjezera ndipo mphamvu yowonjezera ikucheperachepera kufika ku C / 10, batire imatengedwa kuti ndi yokwanira.
Chithunzi 2. Lithium batire charging khalidwe lopindika
1.4 Mphamvu yocheperako yotulutsa
Kutsika kocheperako kumatha kutanthauziridwa ndi voteji yotulutsa, yomwe nthawi zambiri imakhala voteji pomwe mtengo wake ndi 0%.Mtengo wamagetsiwu siwokhazikika, koma umasintha ndi katundu, kutentha, digiri ya ukalamba kapena zinthu zina.
1.5 Kutulutsa kwathunthu
Pamene mphamvu ya batri ili yocheperapo kapena yofanana ndi mphamvu yocheperapo yotulutsa, imatha kutchedwa kutulutsa kwathunthu.
1.6 Kulipira ndi kutulutsa (C-Rate)
Mlingo wa kukhetsa-kutulutsa ndi chiwonetsero cha kutulutsa-kutulutsa komwe kumagwirizana ndi kuchuluka kwa batri.Mwachitsanzo, ngati mugwiritsa ntchito 1C kuti mutulutse kwa ola limodzi, ndiye kuti batire idzatulutsa kwathunthu.Mitengo yosiyanasiyana yotulutsa imapangitsa kuti pakhale mphamvu zogwiritsiridwa ntchito.Nthawi zambiri, kuchuluka kwacharge-kutulutsa, kumakhala kocheperako komwe kulipo.
1.7 Moyo wozungulira
Kuchuluka kwa mikombero kumatanthawuza kuchuluka kwa ndalama zonse ndi kutulutsidwa kwa batri, zomwe zingayesedwe ndi mphamvu yeniyeni yotulutsa ndi mphamvu yopangira.Pamene anasonkhanitsa kukhetsa mphamvu ndi wofanana ndi kapangidwe mphamvu, chiwerengero cha mkombero adzakhala mmodzi.Nthawi zambiri, pakadutsa maulendo 500 otulutsa, mphamvu ya batire yodzaza kwathunthu imatsika ndi 10% ~ 20%.
Chithunzi 3. Ubale pakati pa nthawi zozungulira ndi mphamvu ya batri
1.8 Kudziletsa
Kudzitulutsa kwa mabatire onse kudzawonjezeka ndi kuwonjezeka kwa kutentha.Kudzitulutsa pawokha sikuli vuto la kupanga, koma mawonekedwe a batri palokha.Komabe, chithandizo chosayenera pakupanga kupanga chidzachititsanso kuwonjezeka kwa kudziletsa.Nthawi zambiri, kutsika kwamadzimadzi kudzawonjezeka kawiri pamene kutentha kwa batri kumawonjezeka ndi 10 ° C. Mphamvu yodzipangira yokha ya mabatire a lithiamu-ion ndi pafupifupi 1-2% pamwezi, pamene mabatire osiyanasiyana a nickel-based ndi 10- 15% pamwezi.
Chithunzi 4. Kuchita kwa kutsika kwamadzimadzi a lithiamu batire pa kutentha kosiyana
