Junction Box

The Junction Box in your electric vehicle is a central hub for organizing and distributing power to various systems. It includes terminals, fuses, and circuit breakers for secure wiring, and its strategic mounting ensures accessibility and safety. Regular inspections and adherence to safety protocols during installation and maintenance are crucial for optimal performance.

Functions:

  1. Wiring Hub: The Junction Box acts as a central hub where various electrical wires from different components come together.

  2. Distribution Point: It distributes power and signals to different vehicle systems, ensuring seamless communication and power supply.

  3. Organization: This component organizes the electrical connections, reducing clutter and simplifying maintenance and troubleshooting.

Components:

  1. Terminals: The Junction Box houses terminals for secure connections, enabling the straightforward attachment of wires from different vehicle systems.

  2. Fuses and Circuit Breakers: It incorporates fuses and circuit breakers to safeguard the electrical system against overloads and short circuits.

Maintenance:

  1. Inspection: Conduct periodic inspections to check for loose connections, wear, or any signs of damage.

  2. Fuse Replacement: Safely replace fuses or reset circuit breakers if electrical issues arise.

  3. Resistance test: Connectors for battery cables shall be used when complete traction voltage system requires isolation resistance test.

Safety Considerations:

Always take safety precautions during maintenance, including disconnecting the vehicle from the power source before any work on the Junction Box.

Warning! Do not perform insulation resistance test between positive and negative poles of traction voltage system! This will charge the system and can trigger unexpected power-on or propulsion of the system as well as damage components with higher measuring voltage than system is designed.

By understanding the functions and features of the Junction Box, users can effectively manage and maintain the electrical connections in their electric vehicles, promoting optimal performance and reliability.
