Can Charging Services Be Provided Without Fixed Parking Spaces? Door Energy's Mobile Charging Stations Usher in a New "Shared Charging" Model

Against the backdrop of accelerated global electrification, the number of electric vehicles (EVs) continues to grow. According to data from the International Energy Agency (IEA), the global EV fleet exceeded 40 million vehicles in 2024 and is projected to surpass 200 million vehicles by 2030. However, charging infrastructure is significantly lagging behind.

Traditional charging models heavily rely on fixed parking spaces and grid expansion, which presents significant bottlenecks in urban areas, industrial sites, and roadside assistance scenarios. Therefore, a brand-new solution is emerging-the Mobile EV Charger.

Door Energy is redefining the boundaries of charging services through a "mobile charging station + shared dispatch" model.

I. Why are Traditional Charging Models Failing?

1. Structural Problems of Fixed Charging Stations

Current charging networks primarily rely on fixed charging stations, but this model has significant shortcomings:

Furthermore, fixed charging stations are almost non-existent in scenarios such as highways, remote areas, and construction sites.

2. Data illustrating the severity of the problem

* In Europe, on average, there is only one charging station for every 12 EVs

* Charging wait times in some US states can reach 30-90 minutes

* Over 35% of EV users have experienced "charging anxiety"

Therefore, the industry urgently needs more flexible solutions.

II. How does Door Energy define "shared charging"?

Door Energy's core concept of "shared charging" is:

> Let electricity find the car, not the other way around.

Core Components

* Mobile EV Charger

* Intelligent Dispatch Platform (Supports OCPP)

* Multi-Scenario Power Supply Capability (DC+AC)

Technical Features

Compared to traditional charging stations, this model is closer to "Energy-as-a-Service".

III. How does mobile energy storage and charging support "charging without a parking space"?

1. Flexible Deployment Capabilities

Door Energy's Mobile EV Charger can be quickly deployed in multiple scenarios:

* Roadside Assistance

* Industrial Construction Sites

* Temporary Events

* Remote Areas

2. Multiple Energy Supply Methods

This "dual energy supply mode" ensures continuous operation.

3. Multi-Functional Functionality

In addition to charging electric vehicles, it can also power the following devices:

* Electric Excavators

* Water Pump Systems

* Temporary Lighting

This makes it extremely valuable in industrial settings.

IV. Autonomous Charging Robots: The Ultimate Form of Shared Charging

Door Energy has launched autonomous mobile charging robots in scenarios such as parking lots, further improving sharing efficiency.
