Smart Navigation for Electric Mobility Driving an electric car is awesome but should be anxiety-free. We give you the tools to make routing and charging effortless for your EV drivers and fleets. Our routing engine uses over fifteen different variables to calculate the real-time range of any electric vehicle. We take into account the outside temperature, weather, charge speed, elevation, rolling resistance, real-time vehicle data, and congestion at charge stations. Our routing algorithms then calculate the best route to a user’s destination, with the optimal charge stations in between. Build-in predictive models optimize for total travel-time and travel-costs. This gives drivers the confidence to go Electric. Technologies used: Typescript, NestJs, GraphQL, MongoDB, Neo4J, Postgresql, Redis, RabbitMq, Docker, AWS, Grafana, Prometheus, Kubernetes
