How Charge HQ Works - 101

This page contains instructions for configuring
chargers with Charge HQ
Please refer to our
charger listing for details on supported models and charger specifications.

ChargeHQ is a software tool that operates from servers on the Internet. You configure and use Charge HQ using a smart phone app which talks to these servers which do all the work.

After downloading the app and creating an account, you first connect Charge HQ to your EV or Wall Charger.

For Tesla vehicles you log in to your Tesla app to grant access to Charge HQ and for compatible wall chargers there are individual configuration guides.

Once connected, Charge HQ is now able to send commands to your EV or wall charger to start, stop or vary the speed at which your EV charges.

At this stage you can control the charging of your EV from your phone, and setup advanced charging schedules.

The most common use of Charge HQ is to charge your EV at home using excess solar energy from your rooftop solar PV system.

Most home solar systems today come with WiFi connectivity, and constantly publish data about how much energy they're producing. Charge HQ can access this information via an API after you grant us access to it.

Once granted, we know in near real time what your solar production is and we use the charging control to start, stop or constantly vary the rate of charge to match the available excess solar generation (that's the total production less what your home is already using).

Once setup, it operates on its own, automatically charging your EV from your own solar energy as much as it can and topping up from the grid when there's not enough. You just plug your EV in to the charger as often as you can and the app takes care of the rest.

The Charge HQ app lets you monitor your EV charging in real time and also view charging history which tells you where the energy came from that was used to charge your EV.

That's the simple version, you can learn more in our Frequently Asked Questions and Knowledge Base articles.
