As a critical energy replenishment facility for new energy vehicles, the performance and safety of EV chargers are extremely important. Traditional testing methods often rely on sending chargers to fixed third-party laboratories, a process that is cumbersome and time-consuming. On the other hand, deploying a full set of online testing equipment at every charging station is prohibitively expensive. As a result, EV charger testing vehicles—serving as integrated mobile laboratory vehicles—are gradually being adopted and promoted.

WideIOT provides a solution by deploying data acquisition gateways that connect to onboard controllers, generators, and EV charger testing equipment (such as high-precision power analyzers, programmable DC/AC loads, and electrical safety testers). These gateways collect real-time data including vehicle location, electrical parameters, equipment status, and testing results. The data is then transmitted to the enterprise's cloud-based monitoring and management platform via 5G/4G networks. This enables remote monitoring, alerting, management, and statistical analysis of both vehicles and testing operations, helping to improve equipment and asset management while ensuring reliable and smooth testing processes.

Key Features

The gateway connects to various devices inside the vehicle through multiple interfaces such as serial ports (RS232/RS485), CAN bus, DI/DO, and analog inputs. It collects real-time data on vehicle status (location, speed, trajectory, etc.), generator status (output voltage, current, frequency, power, etc.), and testing equipment readings (charger output voltage, current, power, power factor, operating temperature, etc.).

The gateway reports all data in real time to the cloud-based management platform, enabling visualized monitoring and centralized management of each testing vehicle. Users can view the real-time location of a testing vehicle (on an electronic map), current testing task progress, and various equipment operating parameters. Alert information is also aggregated in real time, making it easy to quickly analyze fault distribution, alert frequency, and take prompt action.

To address potential network fluctuations when testing vehicles are on the road or in remote areas, the gateway features offline data caching and automatic reconnection. It supports local data storage during network outages and automatically uploads the cached data once connectivity is restored, ensuring data integrity and preventing loss of test data due to network issues.

By combining vehicle data and testing data, managers can use the platform to achieve a complete closed-loop workflow: work order issuance → vehicle acceptance → on-site testing → data upload → report generation. This standardizes testing procedures and ensures traceability. At the same time, the system supports statistical analysis of the status of individual EV chargers, providing data-driven support for optimizing testing schedules and uating equipment health.
