Raws li cov tswv tsheb fais fab loj hlob tuaj, ntau tus tswv tsev DIY-inclined xav txog kev txhim kho lawv tus kheej EV chargers kom txuag tau nyiaj. Thaum qee qhov kev tsim hluav taws xob tsim nyog rau cov kws txawj DIYers, xaim lub EV charger muaj kev nyab xeeb loj, kev cai lij choj, thiab kev txiav txim siab. Phau ntawv qhia tob no tshuaj xyuas seb kev txhim kho tus kheej puas tsim nyog, yuav tsum muaj kev txawj dab tsi, thiab thaum twg koj xav tau kev pab cuam tiag tiag.

Nkag siab txog qhov pheej hmoo ntawm DIY EV Charger Installation

Hluav taws xob xwm txheej xav txog

• High-voltage txaus ntshai: EV chargers feem ntau siv 240V circuits (ob chav txheem qhov hluav taws xob)
• Nruam high-amperage loads: 30-80 amps rau cov sij hawm tsim hluav taws kub / hluav taws kub
• Grounding faults: Kev siv av tsis raug tuaj yeem ua rau muaj kev pheej hmoo ntawm hluav taws xob
• DC residual tam sim no: Txawm tias thaum tawm, capacitors tuaj yeem tuav cov nqi txaus ntshai

Kev cai lij choj thiab kev tuav pov hwm

• Voided warranty: Feem ntau charger manufacturers xav tau kev installation
• Cov teeb meem hauv tsev: Kev ua haujlwm tsis raug tso cai tuaj yeem tshem tawm qhov kev pab cuam rau hluav taws xob hluav taws xob
• Tso cai cov cai: Yuav luag txhua qhov chaw txiav txim siab xav tau cov kws kho hluav taws xob muaj ntawv tso cai rau EV circuits
• Rov muag teeb meem: Kev teeb tsa tsis raug tso cai yuav tsum tau muab tshem tawm ua ntej muag
