The Need
Our client was facing challenges in the real time monitoring and connectivity of their EV fleet charging operation. The existing system had multiple limitations such as non-availability of real-time status and locations of nearest charging point to customers, higher cost of maintenance, no integration of enterprise applications such a Payment gateway, ERP, and CRM. These challenges were resulting in very poor customer experience leading to unhappy customers.
Impacts Delivered
- Delivered operational efficiency improvements
- Remote maintenance (minor software error ratification and firmware upgrades) significantly enhancing service availability
- Enabled central management of the entire operations with real-time monitoring, reduced cost of operations, and enabling of prioritized charging
- Self-service capability was enhanced through the service portal, improving customer experience and satisfaction.
Our Solution
- Connected charging station with the back-office using an Open Standard Protocol – OCPP 1.6
- Leveraging location data of the vehicle and the real-time charging station availability status, generated alerts via a mobile application
- A web portal is created that allowed multilevel access – both internal as well external.
- Integration of payment solutions streamlined the billing operations
Cloud Application
- Cloud services were built using Microservices architecture which provides the isolation between different services
- Integrated the charging station to the back-office using with Open Standard Protocol – OCPP 1.6
- JSON over MQTT is used to collect the real time information of the fleets
- The data lake helped the Customers with the flexibility of accessing the information without much hustle.
Web Portal
- The multilevel web portal provided seamless experience to fleet owners for the real time monitoring
- The middleware provided APIs to provide integration to external requirements
- The insights from the platform provider charging point owners to remotely manage the minor technical glitches and firmware updates.
Payment Gateway Integration
- A secure payment gateway integration for the multi directional transactions
- The integration of the charging station to the cloud helped to provide the cost of charging and thus enabling reimbursement of billing to fleet owners
Tools & Technologies
- Charging station Integration – OCPP 1.6 protocol
- JSON over MQTT for real time data collection
