A new mobile charging solution is redefining electric vehicle (EV) convenience by enabling on-demand charging without the need for fixed infrastructure, according to local reports.
Developed by Eraergy, the compact, self-guided unit dubbed a “mobile power bank” can be summoned via a smartphone app to charge vehicles wherever they are parked. Once dispatched, the robot navigates to the car and initiates fast charging within minutes.
The company’s product, known as the Energy Tank, is equipped with battery capacities ranging from 30 kWh to 200 kWh and can deliver up to 120 kW of power. Vehicles with low battery levels can typically be charged in 40 to 60 minutes.
The technology is currently being used in residential communities such as Linliqiao Jiayuan in Nanning, where limited parking and aging electrical infrastructure have made it difficult to install conventional charging stations. With more than 400 EVs in the area, residents often struggle to access charging points.
“This solution allows us to charge at home without going to a station,” a resident said, highlighting the convenience and cost savings.
Industry observers note that the system addresses a key challenge in EV adoption—particularly in older urban neighborhoods where grid capacity and space constraints limit infrastructure expansion. By eliminating the need for fixed charging points, the robots convert existing parking spaces into temporary charging hubs.
Beyond residential use, the company is expanding deployments to hotels, highway service areas, and logistics hubs. In hospitality settings, the solution enables operators to offer EV charging without significant electrical upgrades, while logistics companies can charge vehicles during idle periods.
The concept is also gaining traction among major industry players. Battery manufacturer CATL has introduced a similar mobile charging system called CharGo, which has been deployed at highway service stations during peak travel periods such as the Spring Festival to ease congestion.
While current systems rely on partial automation, companies are working toward fully autonomous operation in controlled environments.
As EV adoption accelerates globally, mobile charging robots are emerging as a flexible and cost-effective complement to traditional charging infrastructure, particularly in areas where installation remains a challenge.
