Recently, Ruishu Intelligence has achieved a major breakthrough!!!

Relying on independently developed 1078 kWh mobile energy storage power station , deployed for the first time in a rail transit setting, The train power supply project at Hai’an South Station in Zhanjiang City, Guangdong Province has been successfully implemented, completely resolving the challenges faced by cross-sea trains in… Power supply challenges during decommissioning, standby, and temporary maintenance periods.

As is well known, during train marshalling and holding operations, power outages often disable the air conditioning in carriages, causing interior temperatures to soar as high as 40°C in summer. “Passengers drenched in sweat while waiting for their trains to be re‑marshalled or held” has long been a persistent challenge for railway authorities. In the past, some railway agencies have attempted to address this issue by deploying giant ice blocks or attaching diesel‑powered generator cars, but these measures were abandoned due to their cumbersome operation and limited practicality.

The deployment of the Ruisu 1078 kWh mobile energy storage power station precisely addresses this pain point, becoming a key asset for railway operations. “Super Power Bank” , also marking Ruisu Intelligence’s official entry into the rail transit energy storage sector.

I. The Ruisu Mobile Energy Storage Power Station Delivers Multiple Practical Benefits

The Ruisu 1078 kWh mobile energy storage power station is tailored to the actual operational needs of the Guangzhou Railway Group, from… Passenger experience, operational costs, operational efficiency, and safety assurance In four key areas, it delivers tangible benefits, helping to enhance the quality and efficiency of railway operations and accelerate their green transformation.

1. Enhance the passenger travel experience

After the energy storage system is put into service, it provides stable power to trains during decommissioning and waiting‑for‑clearance periods. While ensuring the carriage’s air conditioning remains in continuous operation, it also maintains lighting and keeps the cabin temperature stable within the comfortable range of 25–26°C.

A train attendant on the cross-sea service reported: “Once power was restored, the carriages were brightly lit, and the air conditioning provided a pleasant coolness. Both staff and passengers have found the experience to be exceptionally positive.” The deployment of mobile energy storage stations has completely put an end to the awkward “sauna‑like” conditions that once plagued cross‑sea travel.

2. Reduce operating costs

Compared with the conventional solution of adding a diesel‑powered generator, the Ruisu energy storage power station… Can Energy consumption reduced by more than 60% Moreover, it supports charging during off-peak electricity rates, further reducing energy costs. Over the long term, this can help China Railway Guangzhou Group achieve significant operational cost savings, truly delivering dual benefits—both environmental and economic.

3. Improve operational efficiency

Taking into full account the characteristics of railway operations, the energy storage power station is designed as a standard container. Can be directly mounted on a flatbed truck. , eliminating the need for large-scale modifications to the existing railway infrastructure and ferry facilities at the train station, thereby minimizing project renovation costs and construction timelines.

4. Strengthen power supply assurance

Targeting High temperature, high humidity, and high salt spray in Hainan, Zhanjiang, and other regions. In complex environments, the Ruisu mobile energy storage power station, with its specialized design, can reliably withstand harsh operating conditions, ensuring the safety of railway operations.

II. Core Advantages of the Ruisu Mobile Energy Storage Power Station

Ruisu’s successful first‑ever deployment in a rail transit setting, and its status as a trusted partner of the Guangzhou Railway Group, are attributable to the customized design and cutting‑edge technology of this 1,078 kWh mobile energy storage system.

1. High Fire Safety Standards

Energy storage Built-in 3 kW air conditioner, paired with a liquid-cooling system. , enabling precise control of the battery compartment temperature and ensuring compatibility -10℃ to 50℃ A wide operating temperature range.

2. Seamless compatibility

Ruisu integrates with the existing train power supply interfaces of Guangzhou Railway. Powered by a standard 600V DC socket commonly used in railway carriages. ， The DC output side employs 800A×2 dual-channel design , which can directly meet the existing train’s power supply requirements.

3. Safe and Reliable

The mobile energy storage power station boasts a protection rating of up to IP65 , The enclosure is made of precision sheet metal and meets a C4 corrosion‑resistance rating. It can effectively resist the corrosive effects of high-salinity sea spray and high-humidity environments. , at the same time, The device is free from electromagnetic interference. , and will not affect the normal operation of railway signaling systems or train communication equipment.

4. Can be lifted and transferred

The Ruisu mobile energy storage power station adopts a standard container design, Paired with a skid-mounted structure , if necessary, it can be swiftly transferred to a trailer using a crane, Achieve “Fixed Power Supply + Mobile Energy Replenishment” Two-way switching ensures that power is dispatched to wherever it’s needed.

III. Unlocking Rail Transit Across All Scenarios Energy storage

The Ruisu 1078 kWh mobile energy storage power station can Comprehensive coverage across all sectors of rail transit. 。

Provide stable power supply for train marshalling and holding operations. , ensuring the proper operation of in-car air conditioning, lighting, and other equipment, and continuously enhancing the passenger travel experience.

Power Supply for Train Maintenance Operations , providing a safe and stable temporary power supply for equipment maintenance to ensure the smooth execution of maintenance operations.

Temporary power supply for construction along the railway line , addressing the challenge of lacking grid power during field operations and reducing construction costs.
