Stekker works by connecting with a CPO, but we have also developed specific hardware and software integrations for our partners. Whatever is needed for your business to be able to talk to smart charge vehicles or batteries.
When managing the charging sessions of EVs, Stekker mainly communicates with charge points through the CPO. Stekker sends charge plannings to the Charge Point Operator (CPO) which then makes sure the charge point adjusts accordingly.
In our assessment we’ll ask you what your grid connection capacity is and how much is available for charging, and whether you have other flexible assets like solar or batteries.
Smart charging for EVs
Key questions is what kind of charge point hardware and software you currently use. If you have a charge point that communicates wirelessly, like most do nowadays, you’ll be able to implement Stekker. Please inquire about your specific setup, as we are compatible with most locations but exceptions are wide.
Here are some guidelines for the optimal use of the Stekker EMS at any location:
It helps if:
- your charge points have been updated to the latest firmware.
- you have easy access to your switch rooms and distribution boards.
- It helps if you own the contract, charge points and/or grid connection of your location.
- It helps if our Edge module can connect to Wi-Fi at the location.
Stekker works generally by connecting to a CPO. We also do custom hardware integrations through specific partnerships. If you are interested in cooperating as a hardware manufacturer, please get in touch.
As far as compatibility and the Stekker EMS goes: Any location is unique. We have experience integrating with existing solar arrays, energy management systems, batteries, and so forth. We cooperate with CPOs, Battery Energy Management Systems, and DSO’s about grid-aware EV charging.
Other Integration Options
We have made cloud integrations through custom API’s and our own Stekker API
Direct cloud integration with charge points is possible if your charge points support direct cloud connectivity, bypassing the CPO for control commands while maintaining CPO services for billing and authentication.
Local integration using a gateway device can connect to charge points via local protocols like ModBus. This adds hardware but can provide faster response times and work even if internet connectivity is interrupted.
Typical Implementation Timeline
For cloud-based integration through a CPO, implementation often takes one to two weeks after approval. This includes API configuration, testing with a few charge points, and rollout across your network.
Local integration with gateway devices typically takes two to four weeks, including hardware installation and configuration. Complex sites with multiple asset types may take longer, please inquire and we’ll be able to give you a timeline.
What You Need to Provide
You’ll at least need to provide the amount of chargepoints and CPO details.
Please also provide information about:
- Charge point hardware and CPO (software)
- Existing solar and/or battery array at the location
- Grid connection information
- Operational requirements like charging schedules and priorities
- Access for any on-site hardware installation
- Any previous local (grid) issues
