- Wear insulated gloves and safety goggles for personal protection.
Step 2: Access the Hybrid Battery Compartment
- Open the rear trunk compartment of your Prius.
- Remove the cargo floor panel and the storage trays to access the hybrid battery pack.
- Disconnect the orange service plug to disable the high-voltage system. This is crucial to avoid electric shock.
Step 3: Remove the Old Battery Pack
- Use a socket wrench to unbolt the battery bracket and supporting components.
- Carefully disconnect the battery terminals and wiring harness connected to the battery.
- Remove the old battery pack and place it on a non-conductive surface for proper disposal.
Step 4: Install the NexPower V3 Sodium-Ion Battery
- Place the NexPower V3 battery pack into the same compartment, ensuring a secure fit.
- Reconnect the wiring harness and battery terminals tightly. Use the torque wrench to secure the connections to manufacturer-specified torque.
- Wrap exposed wiring with electrical tape or heat shrink tubing for safety.
Step 5: Test the Installation
- Use a multimeter to check the voltage of the newly installed NexPower V3 battery. Ensure it aligns with recommended voltage ranges.
- Reconnect the orange service plug to reactivate the high-voltage system.
- Reinstall the cargo floor panel and storage trays.
Step 6: Final Setup and Test Drive
- Reconnect the 12V auxiliary battery and start the vehicle to ensure everything is functioning properly.
- Look for error codes or warning lights on the dashboard; if any appear, recheck your connections.
- Take your Prius for a short test drive to confirm the smooth operation of the new battery system.
Common Issues During Installation and How to Troubleshoot Them
- Battery Not Recognized by the System:
- Double-check the battery terminals and wiring connections.
- Ensure the orange service plug is fully inserted.
- Error Codes on the Dashboard:
- Verify the voltage with a multimeter to ensure the battery is within the correct range.
- Use an OBD-II scanner to read specific error codes and reset the system if needed.
