【Exhibition Review】CHUROD: Chasing Light in Shanghai, Forging a New Chapter of Energy | This May in Shanghai, a Remarkable Encounter of Light and Power

The sunshine in Shanghai is pleasant in May, with summer breaths already lingering in the wind.。

From May 13 to 15, 2026, the 5th Shanghai International Charging, Swapping, Solar & Energy Storage Exhibition kicked off as scheduled at Shanghai Auto Exhibition Center. Within the over 30,000 ㎡ venue, innovation momentum surged and green energy flowed. Exhibitors, visitors, technicians and purchasers from all regions converged like streams merging into a lake, gathering quietly yet powerfully.

Naturally, Churod was also present, bringing relays, contactors, PDUs, and those tiny yet vital components hidden deep inside charging piles and energy storage systems.

I. We Arrived with Practical Products and Solutions

At the booth, we displayed our full product portfolio one by one. This was not a cold showcase, but a solution set for "how to make charging piles more efficient, reliable and maintainable". Many visitors were attracted by the front-access design of the single-channel module: "The relay board can be replaced without disassembling the whole assembly. It is incredibly practical for maintenance."

Most of the time, these products stay low-key, featuring metal housings, neatly arranged pins and clearly marked parameters. Multiple models support optional contact temperature monitoring.

Yet industry insiders know that every switch of current and every safe interruption under high voltage relies on their silent operation, delivering dual protection for the safe operation of energy storage systems and power batteries.

II. PDU: The Invisible Key Component in Ultra-Fast Charging Piles

Essentially, the core logic of charging piles lies in power distribution from power modules to charging guns. The PDU (Power Distribution Unit) acts as the "traffic control hub" in this process.

As ultra-fast charging piles advance from 360kW to 1000kW+, the number of charging guns and power modules grows in parallel, while the number of switches inside the PDU increases exponentially. Diverse topologies, varying installation configurations and complex maintenance pose a common challenge across the industry.

More importantly, while power modules and charging guns have established industry standards, PDUs remain in a diverse development phase. Varying forms, inconsistent interfaces and different disassembly methods create persistent headaches for operators, including complicated spare parts management, tough maintenance and slow fault recovery.

III. Balancing Performance and Cost | Compact Size, Powerful Intelligence

 To address these industry challenges, Churod delivers an all-in-one PDU solution that is standardized, modular, platform-based and customizable. 

From 80A and 150A to the new-generation 220A/300A high-current platforms, Churod’s latching relays dedicated for charging piles have gone through multiple iterations. Reliability is no empty slogan — every make-and-break of contacts stands the test of time. 

We integrate these components into a standardized relay board adaptable to full-matrix and semi-matrix architectures. It supports 6/8/9/10/12-channel outputs and fits various topologies via busbar configuration. Compared with conventional contactor solutions, our semi-matrix PDU boasts clear advantages in cost, footprint and installation efficiency. 

This was one of the most frequently inquired solutions at the exhibition. 

We also redesigned connection terminals to shift the maintenance logic from “disassemble the whole assembly” to “replace a single board”. To solve space constraints on the side of compact cabinets, we developed a front-serviceable relay board design. With busbars on the rear and relay boards on the front, the board can be replaced by one technician without taking apart the entire assembly, reflecting our relentless pursuit of higher maintenance efficiency.

IV. Beyond Hardware | Vision for Solar, Energy Storage & Charging Integration

Inside the exhibition hall, solar-storage-charging integration was widely discussed. Though the term sounds technical, its essence is simple: store energy harvested from sunlight and supply it to vehicles, forming a simple yet elegant closed loop. Within this loop,

 Churod handles power connection and disconnection, directing electric current to the right place at the right time. Our PDU products support flexible power distribution for charging stacks ranging from 360kW to 2MW. Behind these rational figures lies a plain philosophy: make every kilowatt-hour count.

V. Ultra-Fast Charging Era | The Demand for Smarter Power Distribution

Competition in charging infrastructure is shifting from charging speed to stability, cost efficiency and maintainability. At the core of this evolution lie the reliability and serviceability of power distribution units. 

Churod takes on technical complexity to deliver simplicity for customers. We will continue to deepen our technical layout of dedicated latching relays for charging piles, standardized PDU modules and intelligent control units. Empowering rapid product iteration for clients with platform-based products, we safeguard every charging process with highly reliable solutions. 

Exhibitions bring fleeting encounters, while technology delivers long-term companionship. 

We look forward to meeting you again at a new height of power technology innovation.
