OEM EV Charger Automotive PCB Assembly GPS Tracker PCBA
♦ What is EV Charger PCB?
An EV Charger PCB is the specialized printed circuit board at the heart of every electric-vehicle charger.
It is a multi-layer board that mounts and interconnects all the active and passive components required to draw energy from the grid, convert it to the correct voltage/current profile, and deliver it safely to the vehicle’s battery.
| Application | PCB Requirements | Examples |
|---|---|---|
| Engine Control Unit (ECU) | High-temperature resistance, EMI shielding | Fuel injection, ignition timing |
| Infotainment System | High-speed signal integrity, multilayer | Touchscreens, GPS, Bluetooth |
| ADAS (Radar/LiDAR) | RF/microwave PCBs, low-loss materials | Collision avoidance, adaptive cruise control |
| EV Battery Management (BMS) | High-current PCBs, thermal management | Cell balancing, charge monitoring |
| LED Lighting | Aluminum PCBs for heat dissipation | Headlights, interior lightin |
