Transforming EV Charging Infrastructure With a Scalable, Multi-Tenant Cloud Platform

1. About the Company

ChargeZone is India’s fastest-growing EV charging network, headquartered in Vadodara with a team of over 50. The company operates a rapidly expanding network of charging stations across India and is now extending its footprint internationally. ChargeZone’s mission is to build the backbone of electric mobility by making reliable, accessible charging infrastructure available at scale. As the network grew to encompass multiple hardware vendors, geographies, and operational models, the need for a robust, unified technology platform to manage the entire ecosystem became critical.

2. The Challenge

As ChargeZone scaled its charging network and prepared for international expansion, several deep technical and operational challenges emerged:

• Fragmented Data From Multiple Hardware Vendors: ChargeZone’s network relied on EV chargers from three to five different hardware vendors, each transmitting data in unique, proprietary formats that were neither universally reliable nor easily interchangeable. Integrating this data, standardizing it into a single coherent format, and ensuring it was accurately received and recorded within ChargeZone’s ecosystem was a significant technical challenge that directly impacted the user experience and operational visibility.
  ‍
• International Expansion Requiring Multi-Tenant Architecture: Expanding from India to international locations such as Abu Dhabi introduced a new layer of complexity. The software needed to be adapted for localization, regulatory compliance, and vendor-specific integration requirements across different markets. The existing single-tenant infrastructure was not designed to support the data isolation, configurability, and operational independence that multiple geographies demanded.
  ‍
• Ensuring Real-Time Charger Uptime and Status Accuracy: Maintaining at least 90% charger uptime across the network and delivering 100% accurate, real-time status updates on charger availability to end-users posed a critical technical challenge. Differing operational environments, variable hardware reliability, and inconsistent data feeds made it difficult to guarantee the level of accuracy and availability that EV drivers depend on when planning their charging stops.
  ‍
• A Deep Domain Knowledge Gap in EV and Electrical Engineering: Building a global EV charging ecosystem required expertise well beyond typical software development. The team needed substantial knowledge in electrical engineering, automotive systems, charger functionalities, and electricity consumption metrics — domain areas that are rarely part of a standard engineering team’s skillset but are essential to delivering a technically sound and reliable product.

These challenges demanded not just engineering capability but a willingness to invest deeply in domain expertise and build infrastructure that could scale reliably across vendors, geographies, and operational models.

3. Solution Implemented by Tequity

Tequity partnered with ChargeZone as its dedicated engineering team, taking ownership of the platform’s architecture, vendor integrations, cloud migration, and multi-geography scalability from the ground up.

• Standardized Multi-Vendor Data Using OCPI and a Cloud-First Platform: Tequity implemented a system to standardize data from all hardware vendors using OCPI (Open Charge Point Interface), creating a universal data layer that normalized the proprietary formats from each vendor into a single, reliable stream. The entire ecosystem was migrated to ChargeCloud, a cloud-first platform purpose-built for scalability and operational visibility. Multiple consumer-facing applications were then developed and integrated with ChargeCloud to display the number of available chargers and their current charge levels in real time, significantly reducing booking time for end-users.
  ‍
• Migrated to a Multi-Tenant Architecture for Global Operations: Tequity migrated ChargeCloud from a single-tenant system to a fully multi-tenant ecosystem, where data from international clients was isolated and managed independently while sharing the same core platform. The backend was reconfigured to support this new tenancy model, with each tenant operating under its own compliance, localization, and vendor integration requirements. The architecture now supports 11 tenants running in parallel across different geographies, enabling ChargeZone to scale internationally without the overhead of maintaining separate platforms for each market.
  ‍
• Engineered Real-Time Charger Monitoring and Status Accuracy: Tequity built robust monitoring systems to ensure charger uptime and deliver accurate, real-time status updates to end-users. By standardizing the data pipeline from diverse hardware vendors and implementing reliable health-check mechanisms, the platform was engineered to provide users with trustworthy information about charger availability — a critical factor in building the confidence EV drivers need to rely on ChargeZone’s network for their daily mobility.
  ‍‍
• Invested in Specialized EV Domain Training for the Engineering Team: Recognizing that building a world-class EV platform required more than software skills, Tequity invested in specialized training for 20–25% of the engineering team. This training covered the nuances of the EV ecosystem, charger functionalities, electrical engineering principles, and electricity consumption metrics. This domain investment ensured that every technical decision — from architecture to integration — was grounded in a deep understanding of the physical infrastructure the software was built to manage.

4. Results

The partnership between ChargeZone and Tequity delivered outcomes that fundamentally enabled the company’s growth from a domestic charging network to a global EV infrastructure platform:

• Unified Multi-Vendor Data and Accelerated User Booking: The OCPI-standardized data layer and ChargeCloud integration delivered a single, reliable view of charger availability across all hardware vendors. Consumer-facing apps now display real-time charger status, significantly reducing booking time and increasing app downloads per charging station.
  ‍
• Scaled to 11 Parallel Tenants Across Multiple Geographies: The multi-tenant migration enabled ChargeZone to expand internationally with full data isolation, localization, and compliance for each market — all running on a single, scalable platform. This architecture eliminated the need for geography-specific infrastructure and positioned ChargeZone for continued global expansion.
  ‍
• Achieved Reliable Charger Uptime and Real-Time Status Accuracy: The monitoring infrastructure and standardized data pipeline ensured that charger uptime targets were met and end-users received accurate, real-time availability information — building the trust and reliability that are essential to driving EV adoption at scale.
  ‍
• Built a Domain-Expert Engineering Team: Tequity’s investment in specialized EV training created an engineering team that operates with the domain fluency of an in-house team, capable of making technically informed decisions across software, electrical systems, and automotive infrastructure — a rare and differentiating capability in the clean energy space.
  ‍
• With a scalable, multi-tenant cloud platform, standardized vendor integrations, and a domain-expert engineering team now in place, ChargeZone is equipped to accelerate its global expansion and play a defining role in the infrastructure powering the electric mobility revolution.
