IMPORTANT: Charge HQ does not currently offer support via telephone. We cannot guarantee that we will be available to assist you whilst you are on a clients site.

Confirm client Internet connection availability

Charge HQ requires the wall charger to have a reliable connection to the Internet to operate. Depending on the charger specification this may be via WiFi or Ethernet. Some chargers may also have a built-in 4G/cellular connection.

Confirm with the client that Internet connectivity is available and WiFi usernames & passwords are accessible (if required).

Connect the charger to Charge HQ

This first step involves establishing a connection between the wall charger and Charge HQ by configuring the OCPP settings on the charger.

You might like to complete this step from your workshop/office before you go to the customer's site. Once the charger is successfully connected to Charge HQ, most problems can be resolved remotely. Confirming the connection in advance should significantly reduce the risk of having to complete multiple site visits.

You don’t need access to an electric vehicle to complete the connection process.

Install the Charge HQ app on your phone

You will need to download and install the Charge HQ app on your phone from the Google or Android app stores.

Next, create a personal account for testing purposes.

Connect the charger to your office / workshop Internet

The testing procedure requires an Internet connection. Follow the installation guides provided with the charger to establish an Internet connection to the charger via your local WiFi network.

Configure the OCPP settings

Then follow the steps in the OCPP charger configuration guide to connect the charger to Charge HQ and your personal Charge HQ account.

Note: Record the EVSE ID that was successfully used to connect to the charger, you will need this to complete the charger installation on the client's phone.

Clean up

Once you have confirmed that the charger has connected to Charge HQ, remove the charger from your Charge HQ account by selecting: Home → Menu → My Equipment → Smart Charger → Delete button.

This will remove the charger from your individual user account and allow you to add it to the customer’s account below. The charger will be disconnected from the Charge HQ backend, however the charger will attempt to reconnect continuously.

You may also wish to remove your local WiFi details from the charger configuration at this point.

Install charger & app at the client site

Connect the charger to the Internet

Once the charger is installed and powered up, configure the wall charger to establish a connection to the client's home Internet service per the installation manual provided with the charger.

Configure the client's Charge HQ app

Then using the client’s smartphone go to:

  • Menu
  • My Equipment
  • Select “Connect your Smart Charger”
  • Enter the EVSE ID recorded above
  • Enter the Min and Max Power (Amps) settings as appropriate:
  • Min power is 6 amps for most chargers - refer to the setup guide for your charger on this site.
  • Max power is determined by the installation circuit.
  • Submit

The following screen will show the connection state, monitor this until it indicates that the charger is connected.

Note that some chargers may take multiple minutes to establish a new WiFi connection.

Test Charger Operation

Once the charger Connection State indicates that it’s online you can test control.

  • Plug charger into the client’s EV
  • From the Charge HQ app home screen on the client's phone select:
  • Charge Now - check that the vehicle or wall charger indicates charging is in progress.
  • Adjust the Charge Amps - check that the charging amps change to the requested value.
  • Stop - check that charging stops.

NOTE: it can take up to 1 minute for commands to be reflected on the Charge HQ display. Eg if you change the Charge Amps, please wait at least 1 minute to confirm that the change has worked.

The most important step is to establish the connection between the charger and Charge HQ before you leave the client site. If there are problems with the operation of the service beyond this point they can most often be resolved remotely.
