Safety Advice

Always follow the safety instructions provided with your charger. Always use a qualified electrician where required.

Step 1

Confirm your OCPP compatible charger is currently supported by Charge HQ.

Note for Tesla Owners

Do not attempt to add your Tesla wall charger here! Charge HQ controls Tesla charging via the vehicle and does not need to know about your Tesla charger. If you have both a Tesla vehicle and an OCPP-compliant smart charger that is supported by Charge HQ, you may add them both. Charge HQ will control charging via the smart charger in preference to the Tesla vehicle.

‍

Step 2

• Open the Charge HQ app
• Menu -> My Equipment -> Connect your Smart Charger
• EVSE ID: this will be entered into your smart wall charger, note it down or copy it.
• Min and Max Power (A): Update these if you believe they are different to the default settings.

Note: The EVSE ID is a unique identifier for your charger, it cannot be the same as any other OCPP charger that is connected to Charge HQ. For this reason Charge HQ will provide you with a known-unique value that you can set in your charger.

If you wish to use another value, such as that provided by your charger, you can customise it at the time of adding your charger to Charge HQ.

Step 3

You now need to access the configuration interface for your charger where the OCPP settings are stored. This will vary between each different type of charger per the guides linked below.

In each case you will need to enter the following settings:

• OCPP version (if requested): 1.6 or 1.6J
• OCPP server address: wss://ocpp.chargehq.net/ocpp16/
• EVSE ID: as noted in Step 2

Notes

In some instances the charger may not support connection via a secure protocol, in such cases a non-secure address may be required:

• OCPP server address: ws://ocpp.chargehq.net/ocpp16/

Different charger manufacturers may refer to the above settings via different names, where available please consult the individual charger guide for clarification.

Charger guides:

• ‍ABB Terra AC
• Keba KeContact P30
• MG ChargeHub
• Ocular IQ
• Schneider EVlink Smart Wallbox

Step 4

In most cases you will need to reboot (power down and power up your charger). This can take up to 5 minutes depending on the charger model.

Configuration should now be complete. The Charge HQ home page will display an error if your charger is not connected. See trouble shooting below.

Test connectivity by using the Charge HQ app whilst observing your EV to confirm correct operation. Suggested tests:

• Start and stop charging
• Confirm charging occurs at the configured charge rate (Amps)
• Configure a scheduled charging period

If you need further assistance, please reference knowledge base articles.

Troubleshooting

If your charger is configured but shows as disconnected in Charge HQ, please try the following:

• Double-check the server address and EVSE ID (see above).
• Wait 5 minutes.
• Reboot the charger.
• Wait 5 minutes.
• Try the non-secure (ws://) server address (see above).

If the charger has still not connected please email info@chargehq.net.
