Electric Vehicle Circuit Board Processing
What is an electric car circuit board?
The electric vehicle circuit board acts as the central control unit, overseeing various electronic systems’ functions like start, acceleration, speed, and stop in the electric vehicle. It functions as the vehicle’s brain, making it a crucial component.
Main Parameters and Functional Characteristics of Tianjin Electric Vehicle Circuit Board:
- Rated voltage: Compatible with 12V, 18V, 24V, 36V, 48V, 60V, 72V, and 80V
- Undervoltage threshold: Rated voltage of the battery multiplied by 0.875 (±1V)
- Current-limiting current: Ranges from 4A to 100A (±0.5A)
- Static power consumption: Less than 2W
- Speed limit function: XS interface for restricting driving speed to 20 km/h
- Over-speed function: Utilizes magnetic field weakening for speeds up to 1.5 times the motor’s rated speed
- Cruise mode: XH interface for automatic and manual cruise modes
- 1:1 Power Assist Function: Provides motor power based on the rider’s pedaling force
Electric Vehicle Circuit Board Processing Manufacturers
Electric vehicle circuit board processing necessitates specific information:
- Complete PCB manufacturing documents (Gerber files, placement diagrams, stencil files) and board production specifications
- Comprehensive BOM (including model, brand, package, description, etc.)
- PCBA assembly drawing
*Note*: Reporting PCBA functional test fee requires providing the testing method.
Electric Vehicle Circuit Board Processing Flow
