Digital Transformation of the Roadside Assistance Industry: Achieving Refined Operations of Charging Assistance Using the OCPP Protocol

I. Introduction: With the advent of the electric vehicle era, roadside assistance is entering a "digital power replenishment" phase.

For the past few decades, the core model of the roadside assistance industry has been very simple: vehicle breakdown → assistance vehicle arrives → towing → transport to repair location.

However, with the rapid growth of new energy vehicles (EVs) globally, this traditional model is facing new challenges.

According to data from the International Energy Agency (IEA), the global electric vehicle market is continuously expanding, with global sales of new energy vehicles exceeding 14 million units in 2023, and the global EV fleet surpassing 40 million units. As the number of EVs increases, the problems faced by the roadside assistance industry are also changing: Vehicles may not necessarily have mechanical failures, but may simply be lacking power;

Vehicles may not necessarily need transportation, but rather a rapid restoration of their range;

Rescue personnel are no longer just dealing with "moving broken-down vehicles," but rather "restoring vehicle power."

In the era of gasoline-powered vehicles, a single assistance vehicle carrying repair tools and towing equipment could solve most problems.

However, for EV vehicles, if they are stranded on highways, in remote areas, construction zones, or large parking lots due to low battery, traditional towing methods often mean longer waiting times, higher operating costs, and more complex dispatch processes.

Therefore, the roadside assistance industry is seeking new solutions: Mobile Energy + Digital Management + Intelligent Communication.

This is why Door Energy Mobile EV Charger is gradually becoming an important roadside assistance infrastructure in the era of new energy vehicles.

Door Energy focuses on the research, development, manufacturing, and sales of energy storage and charging products, providing new solutions for roadside assistance, industrial sites, and outdoor energy needs through high-power mobile charging capabilities, OCPP communication protocols, and flexible deployment methods.

Failure Type Gasoline Vehicle EV Vehicle Energy Issues Fuel Depletion Insufficient Battery Power Starting Problems 12V Battery Failure High-Voltage Battery Cannot Continue Outputting Power Environmental Impact Relatively Limited Temperature and Battery Status Have Significant Impact Assistance Methods Refueling, Repair, Towing Mobile Refueling, Fast Charging

As the EV market expands, roadside assistance companies need to redesign their service models.

The future competition will not only focus on "who can arrive at the scene faster," but also on who can restore the vehicle's operational capability faster.

2. Fixed Charging Infrastructure Has Coverage Blind Spots

While a global public charging network is rapidly being built, fixed charging stations still face limitations:

* Fixed geographical location;

* Long construction period;

* Insufficient coverage in remote areas;

* Inability to quickly meet temporary needs.

For example: An electric vehicle has 5% battery remaining on a mountainous section of a highway.

The nearest charging station may be tens of kilometers away.

The vehicle cannot continue driving, and the driver cannot go to charge it themselves.

In this situation, mobile charging equipment is more direct than towing.

3. Roadside Assistance Requires Digital Operational Capabilities

Traditional Model: Receiving a call → Dispatching a vehicle → Arriving at the scene → Assessing the situation → Handling the problem

Digital Model: Data access → Vehicle location → Need assessment → Intelligent dispatch → Mobile EV Charger on-site charging → Data feedback

The difference lies in: Traditional roadside assistance relies on human experience.

Digital roadside assistance relies on data-driven decision-making.

III. OCPP Protocol: Enabling Door Energy Mobile EV Chargers to Become Smart Roadside Assistance Nodes

1. What is OCPP?

OCPP (Open Charge Point Protocol) is an open protocol for communication between charging devices and backend management systems.

Simply put: OCPP enables charging devices to connect to the internet.

For the roadside assistance industry, this means that the Door Energy Mobile EV Charger is no longer just a portable power bank, but a data device that can be managed, monitored, and analyzed.

2. How Does OCPP Improve Roadside Assistance Operation Efficiency?

Through the OCPP protocol, operators can obtain in real time:

* Device online status;

* Current output power;

* Charging records;

* Energy consumption;

* Fault information;

* Operational data.

For example, a roadside assistance company may have multiple mobile charging devices.

Traditional method: It's impossible to know the device's location, battery level, and usage status in real time.

Digital method: The operational status of all devices can be viewed in the backend.

3. Data-Driven Refined Operations

OCPP's greatest value lies in helping companies upgrade from "providing one-time rescue services" to "operating energy services."

Through data analysis:

Companies can understand:

* Which areas have the highest EV rescue demand;

* Which time periods have concentrated tasks;

* Which equipment has the highest utilization rate;

* How much electricity is output per rescue operation.

For example:

This data can help companies deploy equipment in advance and improve response speed.
