Xaiv lub roj teeb lithium rau lub tsheb hluav taws xob (EVs) yuav tsum nkag siab txog cov txheej txheem tseem ceeb tshaj li tus nqi thiab ntau qhov kev thov. Phau ntawv qhia no qhia txog tsib yam tseem ceeb rau kev txhim kho kev ua tau zoo thiab kev nyab xeeb.
1. Tshawb xyuas Voltage Compatibility
Sib piv roj teeb voltage rau koj EV lub tshuab hluav taws xob (feem ntau 48V / 60V / 72V). Tshawb xyuas cov ntawv sau lossis phau ntawv qhia-tsis sib haum xeeb muaj peev xwm ua rau cov khoom puas. Piv txwv li, 60V roj teeb nyob rau hauv 48V system yuav overheat lub cev muaj zog.
2. Analyze Controller Specifications
Tus maub los tswj kev xa hluav taws xob. Nco ntsoov nws qhov kev txwv tam sim no (xws li "30A max") - qhov no txiav txim siab qhov tsawg kawg Battery Management System (BMS) qhov ntsuas tam sim no. Upgrading voltage (piv txwv li, 48V → 60V) tuaj yeem txhawb kev nrawm tab sis yuav tsum muaj kev tswj hwm kev sib raug zoo.
3. Ntsuas Roj Teeb Qhov Loj
Lub cev qhov chaw dictates muaj peev xwm txwv:
- Ternary lithium (NMC): Ntau zog ceev (~ 250Wh / kg) rau ntau yam
- LiFePO4: Lub neej voj voog zoo dua (> 2000 cycles) rau kev them nyiaj ntau zausUa ntej NMC rau qhov chaw txwv qhov chaw; LiFePO4 haum rau cov kev xav tau ua haujlwm siab.
4. Ntsuas Cell Zoo thiab pab pawg
"Qib-A" thov lav tsis ntseeg. Reputable cell brands (xws li, kev lag luam-tus qauv hom) yog nyiam, tab sis cellsib phimyog qhov tseem ceeb:
- Voltage variance ≤0.05V ntawm cov hlwb
- Cov vuam zoo thiab potting tiv thaiv kev puas tsuajThov batch test reports los xyuas qhov sib xws.
5. Ua ntej tshaj plaws Smart BMS nta
Ib tug sophisticated BMS txhim kho kev nyab xeeb nrog:
- Real-time Bluetooth saib xyuas ntawm voltage / kub
- Active ntsuas (≥500mA tam sim no) kom ntev pob lifespan
- Kev txiav txim yuam kev rau kev kuaj xyuas kom zoo Xaiv BMS tam sim no kev ntsuas ≥ tus tswj hwm txwv rau kev tiv thaiv overload.
Pro Lub Tswv Yim: Ib txwm siv tau cov ntawv pov thawj (UN38.3, CE) thiab cov lus lav ua ntej yuav khoom.
