The device is a portable electric vehicle (EV) charging station, specifically the CTEK NJORD® GO, designed for AC charging. It is a Mode 2 charging device, meaning it integrates the control and protection functions within the cable itself, allowing for charging from a standard household or industrial socket. The device comes with a 2-year warranty, indicating a commitment to quality and reliability.
Function Description:
The primary function of the NJORD® GO is to provide a safe and efficient way to charge electric vehicles. It acts as an intermediary between the power source (mains) and the EV, managing the charging process to ensure optimal battery health and user safety. The device supports 3-phase charging, offering flexibility for different power setups. It includes ground fault detection, which is a crucial safety feature that monitors for electrical leakage and can disconnect power if a fault is detected, protecting both the user and the vehicle. An internal energy meter tracks the power consumed during charging, providing useful data for monitoring and billing purposes. The device is designed to be portable, making it convenient for users who need to charge their EV at various locations, and it also offers options for wall-mounting with an accessory kit.
Usage Features:
The NJORD® GO is designed for user-friendly operation, integrating smart features for enhanced control and monitoring.
- Connection to Mains: The device is connected to a CEE 16 A/400 V 3P socket, and its status is indicated by LED lights on the unit. These LEDs show whether the device is receiving power and ready for use.
- Smartphone Integration: A key feature is its connectivity with a smartphone app (CTEK App for Android and iOS). Users are guided to download the app from Google Play or the App Store. This app allows for remote control and monitoring of the charging process.
- Bluetooth® and Wi-Fi Connectivity: The device utilizes Bluetooth® wireless technology for initial pairing with a smartphone and Wi-Fi for broader connectivity, enabling users to manage charging from a distance.
- Charging Control: Through the app, users can initiate and stop charging, monitor the charging status, and view estimated charging times. The app displays the current charge level of the EV battery and the progress of the charging session.
- Locking Mechanism: The device features a locking mechanism for the vehicle connector, which can be activated via the app. This prevents unauthorized disconnection of the charging cable from the vehicle, ensuring security during charging.
- Error Handling: The device is equipped to detect and indicate various errors, such as low battery, power supply issues, or temperature extremes. When an error occurs, the device's LEDs and the smartphone app will display an alert, guiding the user on how to troubleshoot or seek assistance. For instance, if the device detects a power supply issue, it will indicate a problem with the mains connection. If the device's internal temperature or the ambient temperature is outside the safe operating range (-30°C to +50°C), it will halt charging and display a warning.
- Temperature Management: The NJORD® GO incorporates natural convection cooling, meaning it dissipates heat without the need for active fans. However, it is sensitive to extreme temperatures. If the device becomes too hot (e.g., above 50°C) or too cold (e.g., below -30°C), it will indicate a temperature error and may pause or prevent charging to protect its components and the vehicle battery.
- Residential Use: The product is intended for residential use, implying it's designed for typical home charging scenarios.
Maintenance Features:
While the manual does not detail explicit user-performable maintenance tasks, it provides guidelines and warnings that contribute to the device's longevity and safe operation.
- Environmental Considerations: The device is designed for an ambient operating temperature range of -30°C to +50°C. Operating outside this range can trigger error states and potentially damage the unit. Users are advised to be mindful of the operating environment.
- Physical Protection: The device has an external mechanical impact rating of IK10, indicating a high level of protection against physical impacts. However, users are warned against subjecting the device to excessive force, crushing, or dropping it, as this can cause damage.
- Water and Moisture Protection: The illustrations show warnings against submerging the device in water or exposing it to excessive moisture, highlighting its need for protection from the elements.
- Cable Management: Proper handling and storage of the cables are implied through illustrations, suggesting that cables should not be kinked, crushed, or left in hazardous positions.
- Professional Service: In case of persistent errors or malfunctions that cannot be resolved by basic troubleshooting (e.g., power supply issues, temperature errors), the manual directs users to seek professional service. This implies that internal repairs or complex diagnostics should be performed by authorized personnel.
- No User-Serviceable Parts: The warnings against opening the device or attempting unauthorized repairs suggest that it is not designed for user maintenance beyond basic care. Any tampering could void the warranty.
- Ventilation: The manual explicitly states that "This charging station does not have ventilated charging," which refers to the absence of active ventilation for the vehicle's battery during charging, a feature sometimes found in more advanced charging systems. This is a characteristic of the device's design rather than a maintenance instruction.
- Compliance: The device adheres to IEC61851 standard requirements, and users are warned against using unauthorized adaptors or conversion adapters, which could compromise safety and performance.
- Software Updates: As the device integrates with a smartphone app and uses communication protocols like OCPP 1.6, it is likely that software updates will be available to improve functionality and address potential issues, though this is not explicitly detailed as a user maintenance task. Users are encouraged to check the CTEK website for the most up-to-date manual and information, implying that software updates and revisions to maintenance instructions might be released.
