a residential community parking lot in Nanning, China with 400+ electric vehicles
A Nanning Residential Lot Adds EV Charging With Summoned Mobile Robots
How a residential lot in Nanning, China with 400+ EVs added charging through a summoned mobile unit, and what its company-reported numbers mean for US sites.
- 400+
- Electric vehicles served by the residential community
- 1.5 m
- Height of the mobile charging unit
- 100 kWh
- Approximate battery pack in the unit
- 40 to 60 min
- Company-reported replenish time from 10 percent charge
Based on a documented real-world deployment. Figures are from public reporting; the organization is not named.
Charging a lot that was never built for EVs
The residential compound in Nanning had a problem common to older developments. Many were built with too few parking spaces, and nobody planned them around a charger in every stall. For a community with more than 400 electric vehicles, the gap between demand and available charging was the whole story.
Fixed chargers are the usual answer, and they are slow to win. Grid approval for a new charger can be refused when local capacity is exceeded, so an installation that looks simple on paper can stall at the utility office. Trenching and wiring each space adds cost and disruption to a lot residents use every day.
Residents also disliked detours. One resident put the appeal plainly: parking at home means no trips to charging stations, and electricity is cheap.
A mobile unit in place of a charger at every stall
The operator chose a mobile charging unit rather than fixed hardware at each space. The unit stands about 1.5 m tall and carries a battery pack of roughly 100 kWh. A resident summons it with a phone app, and it navigates to the parked car and begins fast charging within minutes.
The project manager said the approach needs no grid retrofit and does not occupy fixed parking spots. That combination mattered in a lot that could not simply add capacity at the transformer and had no spare bays to give up.
Overhead rail systems in some Chinese garages offer another way to avoid a charger at every space. They run on Level 2 AC, so they cannot match DC fast charging, but they are judged sufficient where cars stay parked for long periods, as in residential complexes.
- A resident requests a charge through a phone app
- The unit navigates to the parked vehicle
- Fast charging begins within minutes, with no charger fixed to the stall
- The lot keeps its existing spaces and avoids a grid retrofit
What the reported numbers show, and what they leave open
The headline figure comes from the company behind the system. According to that company, a vehicle at 10 percent state of charge can be replenished in about 40 minutes to an hour. Treat it as a supplier claim until an independent test confirms it on your own vehicles and power supply.
The account describes the operating model more firmly than the performance. It reports a community of more than 400 EVs, a unit that takes no fixed bays and needs no grid retrofit, and residents who value charging at home. It does not report uptime, utilization or cost per session, so those remain open questions for any operator weighing the model.
The category is growing beyond single pilots. Beijing planned 1,000 mobile charging robots across about 150 parking lots, a plan stated in 2025. CATL's CharGo has reportedly been deployed at highway service stations, and as of this review EV Safe Charge's ZiGGY, announced in 2022, is offered in the United States under a charging as a service model with ongoing technical support and maintenance.
What a parking operator should carry into a site decision
Service Robot Co. is a vendor neutral integrator for US businesses, so we assess charging the way we assess any robot placement. The floor, the power, the traffic pattern and the service plan come first, and the robot choice follows from them. A mobile unit that avoids trenching deserves a close look at a lot where the grid is the constraint, but it still needs a site assessment before anyone commits.
We deliver through a lease. A customer works with us on a three-year lease with one fixed payment quoted after a site assessment, and deployment, integration, training and service run through a nationwide US engineer network. Lease terms and service coverage should be checked against your own lot, not against figures from a pilot overseas.
The Nanning account is a useful map of questions, not a benchmark. Ask for independent charge-time data on your own fleet mix, a clear dispatch and maintenance plan for a unit that moves around the lot, and power and liability terms in writing before you rely on a summoned-by-app model in a US garage.
