Wakamboona here kuti voltage yelithium bhatiri inodonha mushure mekunge yazara chaji? Uku hakusi kukanganisa - maitiro akajairika anozivikanwa sekudonha kwemagetsi. Ngatitorei yedu 8-cell LiFePO₄ (lithium iron phosphate) 24V rori bhatiri demo sampuro semuenzaniso wekutsanangura.
1. Chii chinonzi Voltage Drop?
Tichifunga, bhatiri iri rinofanirwa kusvika pa29.2V kana razara (3.65V × 8). Zvisinei, mushure mokubvisa simba rekunze, magetsi anokurumidza kudonha kusvika ku27.2V (inenge 3.4V pasero). Heino chikonzero:
- Iyo yakanyanya voltage panguva yekuchaja inonzi iyoCharge Cutoff Voltage;
- Kamwe kuchaja kwamira, iyo yemukati polarization inonyangarika, uye voltage inodonha neiyoVhura Circuit Voltage;
- LiFePO₄ maseru anowanzo kuchaja kusvika 3.5-3.6V, asi ivohaikwanise kuchengetedza nhanho iyikwenguva refu. Pane kudaro, ivo vanodzikama papuratifomu voltage pakati3.2V uye 3.4V.
Ichi ndicho chikonzero magetsi achiita se "kudonha" achangochaja.
2. Ko Voltage Drop Inobata Capacity?
Vamwe vashandisi vanonetsekana kuti kudonha kwemagetsi uku kunogona kuderedza kushandiswa kwebhatiri. Saizvozvo:
- Smart lithium mabhatiri ane akavakirwa-mukati manejimendi masisitimu anoyera nemazvo uye kugadzirisa huwandu;
- Zvishandiso zvinogoneswa neBluetooth zvinobvumira vashandisi kutarisasimba rakachengetedzwa chairo(kureva, simba rinoshandiswa rekuburitsa), uye recalibrate SOC (State of Charge) mushure mekuchaja yega yega;
- Naizvozvo,kudonha kwevoltage hakuiti kuti kuderedzwa kushandiswa kwesimba.
3. Nguva Yaunofanira Kuchenjerera Nezve Voltage Drop
Nepo kudonha kwemagetsi kuri kwakajairika, kunogona kuwedzeredzwa pasi pemamwe mamiriro:
- Temperature Impact: Kuchaja mune yakakwira kana kunyanya yakaderera tembiricha inogona kukonzera kukurumidza kuderera kwemagetsi;
- Kukwegura Kwesero: Kuwedzera kwemukati kuramba kana kukwira kwega-kuzviburitsa mitengo kunogona kukonzera kukurumidza kudonha kwemagetsi;
- Saka vashandisi vanofanirwa kutevedzera maitiro ekushandisa uye kutarisa hutano hwebhatiri nguva nenguva.
Mhedziso
Kudonha kwemagetsi chinhu chakajairika mumabhatiri e lithium, kunyanya mumhando dzeLiFePO₄. Neyepamusoro bhatiri manejimendi uye akangwara ekutarisa maturusi, isu tinogona kuve nechokwadi chese zviri zviviri chokwadi mukuverenga kwehuwandu uye hutano hwenguva refu uye kuchengetedzeka kwebhatiri.
