Pando Electric is a US-based Electric Vehicle (EV) charging solutions provider operating at the intersection of clean energy infrastructure and software technology. The company designs and manages cloud-connected EV charging networks for a diverse ecosystem of stakeholders, including EV owners, property managers, commercial installers, and Electric Mobility Service Providers (eMSPs). As EV adoption accelerates across the United States, Pando Electric is positioned as a Charge Point Operator (CPO), managing real-time charging sessions, processing payments, and connecting third-party hardware and software partners through a public API platform. To deliver on this mission at scale, Pando required a
cloud-native foundation capable of handling the real-time demands of a growing, multi-party EV
charging network.
As EV adoption surged across the United States, Pando Electric faced a set of deeply interconnected technical and operational challenges that no off-the-shelf platform could solve. The company needed to build its EV charging management platform from the ground up, and every architectural decision carried significant consequences for reliability, scalability, and market positioning.
The core challenge was the need for reliable, undisrupted communication between physical EV chargers and the cloud platform using the OCPP (Open Charge Point Protocol) standard. Simultaneously, Pando Electric needed to architect a true multi-tenant platform serving fundamentally different user roles, EV owners initiating and paying for sessions, property managers overseeing charging assets at their sites, commercial installers commissioning hardware, and eMSP partners integrating Pando’s network into their own services. Each role required distinct interfaces, permissions, and data views, yet all had to operate within a single, cohesive system.
Pando’s growth strategy depended on its ability to integrate third-party hardware providers and eMSP partners through a public API. Without a well-architected, scalable API layer, Pando could not position itself as a leading CPO, limiting its addressable market and slowing partner acquisition at a critical moment in the EV infrastructure build-out.
10Pearls partnered with Pando Electric to architect and deliver a fully cloud-native EV charging management platform built entirely on AWS, designed for real-time performance, multi-tenant complexity, and partner-ready scalability. The solution was delivered as a new implementation from August 2024 through July 2025.
Every layer of the platform, from OCPP communication handling to payment processing to public API delivery, was purpose-built on AWS services selected for their specific fit to Pando’s operational requirements:
Reliable charger-to-cloud communication was the most critical requirement of the entire platform. 10Pearls solved this with a managed, high-throughput messaging layer built on AWS.
Amazon MSK delivered the lossless, low-latency messaging layer that OCPP-compliant EV charging demands, enabling Pando to guarantee session data integrity across every charger in its network, at
any scale.
10Pearls architected the platform’s backend around a serverless-first design that eliminates infrastructure management overhead while enabling elastic scaling in response to real-world charging demand.
The ECS Fargate serverless architecture means Pando’s platform scales automatically as new charging sites go live and session volumes grow, without requiring infrastructure teams to intervene or re-provision capacity.
EV charging platforms generate two fundamentally different categories of data, structured user and transaction records, and high-frequency time-series telemetry from charging sessions. 10Pearls built a purpose-fit data layer for each.
Separating transactional and telemetry data into purpose-fit databases gave Pando the ability to query session history, generate billing records, and monitor charger health simultaneously.
Handling financial transaction data and supporting multiple distinct user roles across a shared platform required enterprise-grade identity management and security controls embedded from day one.
Amazon Cognito’s federated identity model allowed Pando to serve four fundamentally different user types within a single platform.
With EV charging sites distributed across multiple US locations and a growing ecosystem of third-party hardware and eMSP partners, Pando required both a high-performance web delivery layer and a robust, scalable API integration framework.
AWS API Gateway’s tiered usage plans gave Pando a direct commercial mechanism, enabling consumption-based billing for API partners and positioning the company as a scalable, revenue-generating CPO platform for the broader EV ecosystem.
The AWS-native platform delivered measurable improvements across every dimension of Pando Electric’s operations from the moment it went into production.
End-to-end user flows: encompassing sign-up, charging session initiation, and payment processing became 40% faster, directly improving the EV owner experience and reducing friction at every stage of the charging journey.
Operational overhead: was reduced by 30% as a direct result of the serverless-first architecture built on Amazon ECS Fargate and Aurora PostgreSQL Serverless. By eliminating server provisioning, capacity planning, and manual infrastructure management, Pando’s engineering and operations teams were freed from reactive infrastructure work and redirected toward product development and business growth.
Building a Reliable OCPP Data Foundation: The platform achieved lossless OCPP charger-to-cloud communication through Amazon MSK, establishing the data integrity foundation that every other platform capability depends on.
Real-Time Telemetry for Accurate EV Operations: With reliable, real-time charging telemetry flowing through the system, accurate billing, charger health monitoring, and session management all operate with the precision that EV owners and property managers require.
Backed by a public API layer on AWS API Gateway and a multi-tenant architecture ready to onboard new hardware partners and eMSPs, Pando Electric is now positioned as a scalable, partner-ready CPO for the next phase of US EV infrastructure growth.
