Who We Are
We are Vampire.Energy, pioneers in rethinking EV charging IT & cloud infrastructure. Our team blends expertise in OCPP protocol, RabbitMQ broker HA cluster deployments, DevOps, cloud scalability, and embedded security, delivering an open, modular, and future-proof charging ecosystem.
What We Do
We provide OCPP as a Service — a new approach to EV charging operations built for scale and openness. Instead of closed, rigid systems, we deliver modular solutions that grow with your business.
Native OCPP Communication
Open-source RabbitMQ gateway with embedded DevOps and cloud security for resilience and scalability. No middleware hacks, just native OCPP messaging.
Seamless NFC Digital cards
Native Apple & Google wallet integration. Biometric, tokenized security with frictionless tap-to-charge on phone or smartwatch.
Custom Integrations
Tailored deployments with modular add-ons: smart load management, fleet tools, AI troubleshooting. Flexible APIs and white-label solutions.
Frequently Asked Questions
Ready to rethink EV charging? Find answers to common questions about our OCPP as a Service approach, open-source solutions, and scalable cloud infrastructure.
Is it really open-source?
Yes! Our RabbitMQ OCPP gateway is open, auditable, and customizable. You can inspect, test locally, modify, and extend the code to meet your specific needs. We would love to receive your feedback, blog posts about it and your pull requests with bug fixes!
How much does it cost?
Our pricing model is simple & transparent and depends on your specific number of charge points: 1 EUR / month + VAT, with no installation fees or hidden costs. Our platform is designed to be self-service, so your OCPP endpoint will be ready to use in seconds.
What about scalability?
Built on RabbitMQ, it's designed for enterprise-level throughput — from small deployments to national networks. Scale from 20 chargers to 20,000+ seamlessly. Don't take our word for it, read their blog post about it: 1 million MQTT connections.
How secure is the gateway?
Banking-grade security is standard in RabbitMQ and it is provided at two levels: the transport level and the protocol level. The transport level security involves the use of SSL/TLS 1.3 to encrypt the data in transit between the RabbitMQ server and the charging stations. The protocol level security involves the use of authentication and authorization mechanisms to control who can access the RabbitMQ server and what they can do, using WSS, basic auth or client certificates.
What about my existing platform?
You don't have to replace your existing systems. Our OCPP gateway integrates with any infrastructure, based on asynchronous queue workers (AMQP). Start with what you need and add features as you grow — no vendor lock-in, programming language agnostic, no system replacement required.
When will it be available?
We're launching Q4 2025. Early access partnerships and pilot programs are available now. Contact us to join the beta program, we'd love to hear your feedback!
