Ukukhetha ibhethri le-lithium elilungile lezimoto zikagesi (EVs) kudinga ukuqonda izici zobuchwepheshe ezibucayi ezingaphezu kwezimangalo zentengo nobubanzi. Lo mhlahlandlela uveza izinto ezinhlanu ezibalulekile zokuthuthukisa ukusebenza nokuphepha.
1. Qinisekisa Ukuhambelana kweVoltage
Qondanisa amandla ebhethri nesistimu kagesi ye-EV yakho (imvamisa engu-48V/60V/72V). Hlola amalebula esilawuli noma amamanyuwali—amandla kagesi angafani nobungozi ezingxenyeni ezilimazayo. Isibonelo, ibhethri elingu-60V kusistimu engu-48V lingase lishise kakhulu injini.
2. Hlaziya Ukucaciswa Kwesilawuli
Isilawuli silawula ukulethwa kwamandla. Qaphela umkhawulo wayo wamanje (isb, "30A max")—lokhu kunquma ubuncane Besistimu Yokulawula Ibhethri (BMS). Ukuthuthukisa i-voltage (isb, 48V→60V) kungakhuphula ukusheshisa kodwa kudinga ukusebenzisana kwesilawuli.
3. Linganisa Ubukhulu Begumbi Lebhethri
Indawo ebonakalayo ibeka imikhawulo yamandla:
- I-Ternary lithium (NMC): Ukuminyana kwamandla okuphezulu (~250Wh/kg) ebangeni elide
- LiFePO4: Impilo yomjikelezo engcono (>2000 imijikelezo) yokushaja njaloBeka phambili i-NMC yamakhompathimenti anesikhala; I-LiFePO4 ihambisana nezidingo ezihlala isikhathi eside.
4. Hlola Ikhwalithi Yeseli kanye Namaqoqo
Izimangalo ze-"Grade-A" ziqinisekisa ukungabaza. Izinhlobo zamaseli ahloniphekile (isb, izinhlobo ezisezingeni lemboni) ziyakhethwa, kodwa iseliukufanisakubalulekile:
- Umehluko we-voltage ≤0.05V phakathi kwamaseli
- I-welding eqinile kanye ne-potting ivimbela ukulimala kokudlidlizaCela imibiko yokuhlolwa kwenqwaba ukuze uqinisekise ukuvumelana.
5. Beka kuqala Izici ze-Smart BMS
I-BMS eyinkimbinkimbi ithuthukisa ukuphepha nge:
- Ukuqapha kwe-Bluetooth kwesikhathi sangempela kwe-voltage/izinga lokushisa
- Ukulinganisa okusebenzayo (≥500mA yamanje) ukuze kunwebe ubude bempilo yephekhi
- Iphutha lokungena ukuze uthole ukuxilonga okusebenzayoKhetha izilinganiso zamanje ze-BMS ≥ imikhawulo yesilawuli yokuvikela ukugcwala kakhulu.
Ithiphu Yephrofayili: Hlala uqinisekisa izitifiketi (UN38.3, CE) nemibandela yesiqiniseko ngaphambi kokuthenga.
