Tunkia EV Charger Testing: Portable Testers, Resistive Loads, and Traceability

An EV charger that delivers the wrong energy reading, or fails under load, is both a billing problem and a safety problem. As charging infrastructure expands, operators, utilities, manufacturers, and service providers need a way to verify charger accuracy and performance in the field, in the lab, and across the instruments used to test them.

Why EV Charger Testing Matters

EV charging stations are measuring instruments as much as power equipment. Their output and metering have to be verified at commissioning, during maintenance, and after repairs. Without traceable test equipment, it is difficult to document that a charger performs as specified under real operating conditions.

Tunkia EV Charger Testers and Loads

Tunkia offers a line of electrical test equipment designed for EV charger testing. The range available through AV-TEK Consulting includes:

• TD1320: portable tester for DC EV chargers.
• TD1330: portable tester for AC EV chargers.
• TK4830: portable tester for both AC and DC EV chargers.
• TK4710 and TK4720: DC and AC adjustable resistive loads for on-site testing under load.
• TK4800: calibration device for portable EV charger testers.

Where These Solutions Fit

Tunkia solutions cover the main stages of EV charger verification:

• On-site testing: portable testers combined with adjustable resistive loads to check charger performance in real operating conditions.
• Vehicle-mounted testing: test setups for performance verification in the field.
• Laboratory testing: in-depth analysis and validation of charger efficiency and durability.
• Traceability of test instruments: calibration of the portable testers themselves, so field results can be traced back to a reference.

How AV-TEK Consulting Supports You

AV-TEK Consulting helps you choose the right combination of tester, load, and calibration device for your chargers (AC, DC, or both) and your testing environment. We support technical selection, configuration, quoting, and application questions for EV charger testing programs in North America. For the regulatory and metrological background, see why metrological testing of EV chargers is necessary.

FAQ

Which Tunkia tester should I use for DC fast chargers?

The TD1320 is designed for DC EV chargers, and the TK4830 covers both AC and DC. Contact us to confirm the right model for your charger ratings.

Why use an adjustable resistive load during charger testing?

A load lets you test the charger while it is delivering power, which reflects real operating conditions better than a no-load check. The TK4710 (DC) and TK4720 (AC) are adjustable resistive loads for this purpose.

How are the portable testers kept traceable?

The TK4800 is a calibration device for portable EV charger testers, supporting traceability of the instruments used in the field.
