Is your old charging infrastructure holding you back? 

For fleet managers and EV infrastructure planners, this is the question that should guide your operations. If you’re grappling with the limitations of Generation 1 non-OCPP (Open Charge Point Protocol) or chargers from a vertically integrated charge point operator (CPO), you’re not alone. Outdated technology, poor interoperability, and proprietary systems present significant hurdles for those aiming to optimize and expand their EV charging infrastructure. 

The solution? A strategic move to modern, OCPP-compliant systems that prioritize scalability, flexibility, and cost-saving efficiency. Here’s everything you need to know to upgrade your charging solutions and future-proof your fleet. 

Understanding Gen 1 Non-OCPP chargers

Before we cover how to scale, it’s important to first identify the type of chargers installed at early EV adoption sites. Gen 1 chargers refer to early EV charging units, primarily developed before 2015. These chargers are typically Level 1 or Level 2 systems, often limited in functionality due to non-networked designs. Without connectivity to cellular networks, Wi-Fi, or smart features, they lack the essential hardware and software for advanced fleet requirements like load management or long-term interoperability. 

Key characteristics of Gen 1 chargers: 

  • Outdated hardware with limited or no software updates 
  • Often proprietary, locking users into a single product ecosystem 
  • Lacking smart charging or remote monitoring features 
  • Examples include early versions of ClipperCreek LCS-25, ChargePoint CT1000, and Blink Level 2 chargers 

While these chargers served their purpose at a time when fleets were small and EV adoption rates were nascent, they fall short in meeting the demands of today’s advanced EV fleets.

Why interoperability matters

When managing an electric fleet, one of the most critical factors for success is interoperability. Simply put, interoperability ensures seamless communication between your chargers, vehicles, and charge management software, regardless of brand. Charging solutions from vertically integrated charge point operators (CPO) often lack this flexibility, locking you into proprietary systems that don’t play well with others. 

It’s time to upgrade to OCPP-compliant solutions—not just to improve functionality but to address the challenges that come with proprietary systems. 

Common challenges with vertically integrated chargers:

Limited compatibility 

Non-OCPP chargers often only integrate with proprietary software, leaving little room for expanding site operations with new hardware or communication with third-party platforms. 

Higher costs and vendor lock-in 

Relying on a single vendor limits flexibility and often results in expensive upgrades or replacements when scaling becomes necessary. 

Time-consuming manual management 

Without seamless cross-platform communication, managing charging operations becomes labor-intensive and error-prone. 

Reduced resilience in a changing market 

Should a proprietary vendor discontinue their product or exit the market, organizations may face a costly “rip-and-replace” scenario for their entire infrastructure. 

The smart move to OCPP-compliant systems

The shift to interoperability and OCPP-compliant chargers aims to eliminate the issues caused by proprietary systems, empowering fleet owners with flexibility, scalability, and robust system integration. OCPP acts as the universal language within EV infrastructure, enabling chargers, vehicles, and software tools to communicate seamlessly, regardless of manufacturer. 

Benefits of OCPP-compliant systems: 

  1. Mix and match hardware 

With an open standard, you can choose chargers from multiple manufacturers, offering greater flexibility tailored to your budget and needs. 

  1. Integrate smart charging software 

OCPP makes it possible to deploy tools that optimize charging schedules, reduce demand charges, improve energy efficiency, and prioritize operational uptime. 

  1. Future-proof your fleet 

Easily upgrade or scale as your operations grow and as new EV models and industry technologies emerge. 

  1. Reduce vendor reliance 

No more being locked into one ecosystem. OCPP gives you the freedom to switch or update systems without entirely overhauling your setup.
