GEVCT101 EV Charging Tester
Product Information
The EV Charging Tester is a device used to determine the status
of rapid/standard charges, high-voltage relay, and detect any
abnormalities in the rapid and high-voltage charging path of an
electric vehicle.
Precautions
When handling high-voltage parts:
- Always separate the safety plug to cut off the high voltage
before inspecting or repairing the high-voltage system. - Remove any metal substances from your body to avoid
high-voltage short circuits that can cause harm to humans and
vehicles. - Wear personal protective equipment for safety accident
prevention when working with high voltage. - Prohibit anyone without protective equipment from touching any
part related to high-voltage parts.
When utilizing the product:
- Keep the equipment clean by removing foreign substances before
and after use. - Familiarize yourself with the manual’s contents to follow
procedures and instructions. - Refer to safety instructions for vehicle management issued by
the manufacturer before using the equipment. - Use the equipment in a well-ventilated space and wear
protective equipment like glasses and gloves. - If the equipment is damaged, stop using it immediately and
request repair work from the manufacturer. - The CP/PD voltage check connectors should only be used by
trained professionals.

Precautions
Precautions when handling high-voltage parts
Before inspecting or repairing high-voltage system, make sure to separate the safety plug to cut off the high voltage.
Make sure to remove metal substances (watch, ring, and other metal products, etc.) from your body as they may cause high-voltage short circuit, which causes human and vehicle damages.
Before starting any operation related to high voltage, please wear personal protective equipment for safety accident prevention.
Please make sure that persons other than the operator wearing the protective equipment are prohibited from touching any part related to high-voltage parts.
Precautions when utilizing the product
Remove foreign substances from the component and keep its cleanliness before and after using the equipment.
Make sure you familiarize yourself with contents of the manual before use, in order to follow the procedures and instructions.
Before using the equipment, please familiarize yourself with safety instructions for vehicle management, which were issued by the manufacturer of the vehicle.
Use the equipment only in a well-ventilated space, and make sure to weak protective equipment (protective glasses and gloves, etc.).
If the equipment is damaged by external shock, immediately stop using the equipment. If the equipment needs to be repaired, make sure to request the equipment manufacturer to perform the repair work. (Abnormal repair may become the cause of equipment damage)
The equipment must not be exposed to rain or snow. The equipment must not be used for purposes other than the purpose of its manufacture. Do not leave the equipment being installed in the vehicle. If you do not use the equipment within its operating temperature range (0 40 ), it may
become the cause of its breakdown.
These connectors are used for CP/PD voltage check and only trained professionals should use (or access).

Self-test on the test equipment
Menu
Description of function
This is a function for checking whether there is abnormality in the charging gun when an error occurs while the main test function is being operated, or if there is no change in voltage in connection test.
Description
Once you enter into the function screen, the self-test will be run right away, and the results will be shown on the screen after approximately 20 seconds.

2. Rapid charging line test This is a test that checks whether there is abnormality in the rapid charging line that goes through [high-voltage battery -> inverter -> charge port] through the path of the high-voltage rapid charge port.
Determination condition
Comparison between *the charging equipment measured values and *diagnostic communication values
Charging equipment measured value: BMU controller’s diagnosis communication voltage value
Diagnostic communication value: actually measured voltage value of the high-voltage rapid charge port
Reference
If the test result is NG, it will receive the breakdown status from the vehicle to indicate the problematic part as red light on the screen, and display the AS response method. (Only the vehicle models after IONIC 6 can operate this function)
