Application Review

EVsense can review charger type, rated current, cable path, PCB space, and enclosure requirements before recommending a suitable sensor.

Testing Capability

In-house Type B leakage current testing capability supports product validation and pre-compliance engineering work.

FAQ

Questions engineers usually ask first

What is Type A + DC 6mA residual current detection?

It refers to residual current detection for AC leakage and smooth DC leakage up to the DC 6mA threshold commonly required in EV charging safety designs.

Which standards should be considered?

Common EV charging references include IEC 62955 for RDC-DD, IEC 61851 for conductive charging systems, and IEC 62752 for Mode 2 IC-CPD.

How should I choose a model?

Start with charger type, target region, rated current, PCB layout, required integration level, and whether current transformer functions are needed.

Can EVsense provide samples and datasheets?

Yes. Use the inquiry form with your target product model and charger application so the engineering team can respond with the right materials.
