Challenge
Our client is a recognized United Kingdom-based engineering company with longstanding experience in varying business streams of engineering from electrical and energy service industries to the electric vehicle industry and more. They are progressive and are going to be the largest owner-operator of rapid DC charging stations in the UK.
The client’s services have benefitted electric vehicle drivers, the landowners that house the charging units, and ultimately, the UK’s environment by supporting the use of less polluting electric vehicles. The client’s primary goal was to develop their e-Mobility Service Provider platform which will allow them to take ownership of the driver experience and provide the ability to target customers, which will in turn drive the increase charging station utilization and brand awareness.
It was challenging for the client to develop a solution because of certain critical challenges faced by them such as
- Integration with the ChargePoint, Inc CPO based on the open standard OCPI interface
- Driver Mobile applications for both Android and iOS
- Driver Web Portal
- Fleet Management Portal
- Platform Administration User Interface
- Payment processing mechanism

Solution
After thoughtful planning and research, the expert software development team of TatvaSoft outlined a plan to develop a platform considering all the prerequisites of the Client. We developed a solution with all-inclusive functionalities required for an e-Mobility Service Provider. E-Mobility Service Providers offer EV charging services to EV drivers. An EMSP provides access to a variety of charging points around a geographic area. MSPs help EV drivers find charging stations, start charging events and pay with various payment methods.
We developed a platform that delivers the following software components to provide a world-class experience to the drivers for an e-Mobility Service Provider platform. We utilized the latest and greatest technologies like Node.JS, Kotlin and Swift to develop a custom platform with accompanying apps. We divided the whole solution into three basic sections:
