Our Client was looking for a Gateway that connects their EV charging units to EV Charge Management platform. The customer was interested to develop a Gateway that not only interfaces with EV charging stations, but also can be securely integrated with a typical Building management solutions that gives them the flexibility to offer additional service offerings to their end customers.
- A ‘SmartCharger” Gateway has been developed to provide cloud connectivity for OpenEVSE or Z-wave based vehicle charging stations.
- The gateway enabled vehicle charging stations to be controlled and monitored over azure based custom management solution
- The integrated solution allows end customers to start charging sessions on request.
- The Gateway acts as a generic IoT gateway that connect multitude of smart home devices leading to enhanced home automation solution.
- The gateway uses open source technologies like OpenHAB for secure IoT device management.
Outcome and Benefits Delivered
- Enabled the client to connect their EV charging units to the cloud based management application
- The gateway also enabled the client to provide Home automation solutions along with EV charging solution
- End-customers were enabled to initiate charging sessions on their own
- The gateway has an interface for locally initiate charging sessions in case of cloud/internet outage.
