Meet Meishuo at Booth 1B35:Relay Applications for EV Charging, Energy Storage and Smarter Power Systems

A closer look at the switching components behind new energy equipment

The transition toward electrified transportation and distributed energy is creating new requirements for the components inside charging equipment, inverters, UPS systems and energy storage products. These systems may look different at the application level, but many depend on the same engineering fundamentals: controlled switching, dependable isolation, compact integration and stable operation across repeated cycles. At CPSE 2026, Zhejiang Meishuo Electric Technology Co., Ltd. will invite visitors to explore these requirements through its new energy and energy storage relay portfolio. The exhibition will take place from November 25 to 27, 2026, and Meishuo will welcome visitors at Booth 1B35. The event is an opportunity for equipment designers, sourcing teams, system integrators and product managers to discuss how relay selection affects real-world power-control performance. Rather than treating the relay as a final catalogue item, engineering teams can review the relationship between the relay, the control board, the load, the enclosure and the complete operating sequence.

Why relay application details matter in EV charging and energy storage

An EV charger or energy storage system may include power conversion, monitoring, protection and communication functions in one connected product. A relay can be used to control a circuit, connect a load, provide an interface between a low-power controller and a higher-power function, or support a defined isolation strategy. The correct choice depends on more than the label on the component. Application questions may include:

• Does the relay coil match the controller’s available voltage and drive circuit?
• Is the switched load resistive, inductive, capacitive or a combination of conditions?
• Does the system experience an inrush current that is significantly higher than its normal operating current?
• How often will the relay switch during normal operation, standby, protection or fault recovery?
• Does the design need a particular contact arrangement or contact gap?
• Can the PCB and enclosure provide the required spacing, thermal path and mechanical support?
• How will the selected component be validated before mass production?

These questions connect the electrical design with the product’s use case. For example, an EV charger may have a different switching profile from a PV inverter, even when both are part of the new energy market. An energy storage control unit may also require a different relay interface from a UPS system. Application-based selection helps avoid assuming that one relay structure is suitable for every power-electronics platform.

Meishuo products highlighted at CPSE 2026

The supplied exhibition invitation highlights MPQ1, ME108, ME109 and ME106 for new energy and energy storage applications. MPQ1 is shown with a 60A switching capability and 4kV insulation reference in the invitation. The listed application directions include PV inverters, UPS systems and EV charging. For a design team, the practical starting point is to compare the relay’s intended switching role with the actual load, control method and isolation requirements of the target equipment. ME108 is shown as a dual-group high-power PCB relay with a 35A, 277VAC reference. The invitation lists PV inverter, UPS, EV charger and APF applications. Its dual-group format can be discussed in relation to board architecture, channel organization and the way the equipment separates or coordinates control functions. ME109 is presented as a high-load-capacity relay with a maximum 50A reference and multiple contact-gap options. The invitation associates it with PV inverter and UPS applications. Contact-gap selection should be treated as an engineering topic connected with load behaviour, isolation needs and the equipment’s validation requirements. ME106 is shown with a 32A switching capability and multiple contact-gap options for new energy and industrial control. It may be relevant for compact switching tasks where designers need to balance load handling, contact configuration, installation space and control-board integration. All figures and application descriptions above come from the supplied Meishuo invitation. Buyers should confirm current datasheets, test conditions and final technical suitability before approving a relay for production use.

From exhibition conversation to engineering evaluation

A useful exhibition discussion should start with the customer’s actual system rather than with a generic product request. Visitors can bring a basic application brief covering the control voltage, load type, current profile, inrush, switching frequency, contact arrangement, installation space and project stage.

For an early-stage project, the main question may be whether the relay structure can fit the electrical and mechanical concept. For a mature project, the discussion may focus on validation evidence, alternative parts, supply continuity, process consistency and documentation. For a contract manufacturer or sourcing team, the priority may be a clear specification that can be communicated across engineering, purchasing and production.

This is where a component supplier’s application understanding becomes valuable. Relay selection is not only about choosing a nominal current. It is about making sure the component works within the circuit, the environment and the operating sequence that define the finished product.

A practical checklist for visitors

Before visiting Booth 1B35, engineering and sourcing teams can prepare to explore CPSE 2026 EV charging relay solutions for smarter power systems.

Application: Is the target product an EV charger, PV inverter, UPS, APF unit, energy storage controller or industrial control system?

Electrical conditions: What are the coil voltage, load type, normal current, inrush current and switching frequency?

Mechanical conditions: What PCB footprint, terminal arrangement, height, contact gap and enclosure constraints apply?

Reliability conditions: What operating cycle, ambient temperature, protection circuit and validation method will be used?

Project conditions: Is the project at concept, prototype, qualification or mass-production stage?

A focused brief makes it easier to compare possible relay structures and identify what must be verified before design release.
