Mini CHAdeMO Plug: A Compact 1000V DC Connector for Bidirectional EV Charging


What Is the ELECTWAY Mini CHAdeMO Plug?

The ELECTWAY Mini CHAdeMO Plug is a compact DC charging connector designed for CHAdeMO-compatible charging and discharging equipment. It is intended for equipment manufacturers developing bidirectional EV power systems, portable DC chargers, and integrated charging solutions.

The connector is rated for 1000V DC, with a rated current range of 10–30A and a maximum current of 50A according to the product specification. It also features PT1000 temperature sensors on both DC+ and DC− terminals, an electronic solenoid lock with position feedback, plug-in detection, and customizable cable options.

For product-specific details and configuration discussions, see the ELECTWAY Mini CHAdeMO Plug product page.

What Is a CHAdeMO Connector?

CHAdeMO is a DC fast-charging interface developed in Japan. It is used by compatible electric vehicles and charging equipment, and is also associated with bidirectional power applications such as Vehicle-to-Home (V2H), Vehicle-to-Grid (V2G), and Vehicle-to-Vehicle (V2V).

In a conventional charging session, electricity flows from the charging equipment to the vehicle. In a bidirectional system, power can also flow from a compatible vehicle battery to a home, the grid, or another vehicle. This requires more than a connector: the vehicle, power-conversion equipment, communication protocol, and control system must all support the intended operating mode.

ELECTWAY also supplies a wider range of CHAdeMO charging connectors for EV charging equipment and connector integration projects. For projects that also require a receiving interface, see the CHAdeMO socket product page.

1000V DC Performance and Key Specifications

The Mini CHAdeMO Plug combines a compact form factor with a 1000V DC rated voltage. Its current capacity depends on the selected configuration and operating conditions; manufacturers should confirm the required rating for the target system before finalizing a design.

  • Rated voltage: 1000V DC
  • Rated current: 10–30A
  • Maximum current: 50A (as specified)
  • Contact resistance: 0.5 mΩ maximum
  • Insulation resistance: Greater than 100 MΩ at DC 1000V
  • Withstand voltage: 3000V AC for 1 minute
  • Operating temperature: −30°C to +50°C
  • Protection rating: IP54 when mated / IP44 when unmated
  • Contact terminal: Silver-plated copper alloy
  • Housing material: UL94 V-0 flame-retardant thermoplastic

The contact-terminal material is designed to provide electrical conductivity and low contact resistance. Actual performance must be evaluated within the complete equipment design and under the applicable operating conditions.

Safety and Connection Monitoring Features

PT1000 temperature monitoring on DC+ and DC−

PT1000 sensors are installed on both power terminals to monitor contact temperature. The sensor feedback can be connected to the equipment’s monitoring and protection system so that the system can identify abnormal temperature increases and respond according to its control strategy.

Electronic solenoid locking with status feedback

The connector uses a 12V or ±12V solenoid locking mechanism with position-status detection. The lock helps secure the connection during operation, while feedback allows the equipment controller to check the locking state. A manual emergency-unlock slip key is also provided.

Plug-in detection

The locking mechanism is designed not to engage unless the connector is properly inserted. This supports connection management and helps prevent the connector from being locked in an incorrect insertion state.

Durable housing and mating cycles

The connector is rated for more than 10,000 mating cycles under no-load conditions. Its UL94 V-0 flame-retardant thermoplastic housing and IP54 mated / IP44 unmated protection ratings should be considered when assessing the intended installation environment.

Customizable Cable Options

Different charging products have different cable-routing, installation-space, and handling requirements. ELECTWAY offers the following Mini CHAdeMO Plug configuration options:

  • Cable diameter: 13–21 mm
  • Cable material: TUP or TPE
  • Cable length: customizable from 2 m to 10 m
  • Locking voltage: 12V or ±12V solenoid lock

The ergonomic handle is designed for comfortable handling, while the locking-type latch helps reduce unwanted loosening during use. Equipment manufacturers should confirm cable dimensions, material, length, and locking-control requirements during project specification.

Applications in EV Charging and Bidirectional Power Systems

Vehicle-to-Home (V2H)

A compatible V2H system allows an EV battery to supply electricity to a residential power system. Depending on the inverter, control system, vehicle compatibility, and installation, this can provide backup power for selected household loads.

Vehicle-to-Grid (V2G)

V2G systems enable controlled, two-way electricity exchange between compatible EVs and the grid. Depending on local regulations and system design, potential use cases include energy management, peak-demand support, and grid services.

Vehicle-to-Vehicle (V2V)

A V2V system transfers energy from one compatible EV to another through suitable power-conversion and control equipment. It can be used in emergency charging and roadside-assistance solutions.

Portable DC charging and mobile power equipment

Compact connectors can be incorporated into selected portable DC EV chargers and mobile charging systems where the connector rating and system architecture are compatible.

Integrated charging, discharging, and testing equipment

The Mini CHAdeMO Plug can be considered by OEMs developing integrated charge/discharge equipment, energy-storage interfaces, and CHAdeMO-compatible test systems. Compatibility must be verified at the vehicle, power-electronics, communication, and control-system levels.

For an example of a CHAdeMO-based vehicle-to-home and vehicle-to-vehicle power product, see ELECTWAY’s V2H / V2V inverter.

How to Select a Mini CHAdeMO Plug for an OEM Project

  1. Voltage and current: Confirm the system’s operating voltage and required current. The product specification lists 1000V DC, 10–30A rated current, and 50A maximum current.
  2. Cable configuration: Specify the cable diameter, material, and length according to the equipment layout.
  3. Locking control: Confirm whether the system requires a 12V or ±12V solenoid lock and compatible position feedback.
  4. Temperature monitoring: Check that the PT1000 sensor wiring and signal interpretation are compatible with the equipment controller.
  5. Environmental protection: Evaluate the IP54 mated and IP44 unmated ratings against the installation and operating environment.
  6. System compatibility: Verify vehicle compatibility, power electronics, communication protocol, control logic, and applicable CHAdeMO requirements.

For OEM and customized charging-equipment projects, confirming these points early can help reduce integration changes and ensure that the selected connector configuration matches the application.
