Why is the OCPP protocol considered the golden key for Door Energy to unlock a global charging network?

I. Introduction: A Key Breakthrough from "Issues of Equipment" to "Global Interconnectivity"

Against the backdrop of the accelerating global electrification wave, Mobile Electric Vehicle Charging is evolving from a "supplementary solution" to "critical infrastructure." Especially in high-intensity operational scenarios such as roadside assistance, port terminals, and construction projects, traditional fixed charging networks can no longer meet the demands for flexibility and responsiveness.

However, a core question remains: How to achieve interconnection between different countries, different operators, and different systems?

The answer is-OCPP (Open Charge Point Protocol).

For Door Energy, OCPP is not just a communication protocol, but also the "underlying passport" for its mobile charging devices to enter the global market and establish a unified charging ecosystem.

II. What is OCPP? Why is it an industry standard?

OCPP (Open Charging Point Protocol) is a standard communication protocol widely adopted by the global charging industry for connecting:

* Charging devices (Charge Points)

* CSMS (Customer Service Management System)

OCPP Core Capabilities Breakdown

As of 2025, over 85% of public charging networks worldwide use the OCPP standard (penetration rate even exceeds 90% in the European market).

III. The "Charging Island" Problem in the Electrification Process

Before OCPP, the industry faced severe fragmentation:

1. Incompatibility between different systems

Different manufacturers used proprietary protocols, resulting in:

* Devices could not connect to third-party platforms

* Operators were "locked in"

2. Difficulty in cross-regional operation

Especially in the European and American markets:

* A fleet operates across multiple countries

* Requires access to multiple charging networks

3. Inability to scale mobile charging equipment

For Mobile EV Chargers:

* Requires re-integration of systems every time they enter a market

* Extremely high costs
