CTEK APP

The CTEK APP keeps you on top of all your compatible CTEK charging products, right there in the palm of your hand.

Quickly installed and simple to use, the CTEK APP syncs your CTEK products to your smartphone via BLUETOOTH® and Wi-Fi, or by using BLUETOOTH® only.*

From the clear, easy to read home page you can check the status of all CTEK products that are within range and unlock extra product features to give you even more control. It’s designed to work effortlessly with all compatible CTEK products, including the NJORD® GO portable EV charger** and the CTEK CS ONE smart charger.

Get the most out of your NJORD® GO EV charger
The CTEK APP gives you total control over how and when you charge your EV with your NJORD® GO. Simply connect it to the app over BLUETOOTH® or Wi-Fi and you can:
• Access additional NJORD® GO features and functions
• Start, stop and pause charging remotely, and enable or disable auto start
• Schedule charging for any time of day
• Increase or lower the output current during heavy domestic power usage
• Record and display your entire charging history

Open up additional features on your CS ONE smart charger
• Connects automatically over BLUETOOTH®
• Revive deeply discharged batteries using the ‘RECOND’ reconditioning mode
• Select ‘LITHIUM WAKE UP’ for lithium-ion batteries with Under Voltage Protection (UVP)
• Turn your CS ONE into a 12V power supply using ‘SUPPLY’ mode to support the battery during service work
• Displays charger voltage and amperage

What’s New

• Full charging history page (NJORD GO only)

* BLUETOOTH® and Wi-Fi compatibility is subject to product type. Some connected product functions might not be available.

** We call the NJORD® GO an ‘EV charger’ but technically speaking, it’s ‘Electrical Vehicle Supply Equipment’ (EVSE) that provides a safe supply of electricity to power the on-board battery charger in your EV. Most people use the term ‘EV charger’ so to keep things simple, we’re going to use this term as well.
