Charging connector contact-resistance and temperature-rise test control

Applicable purchasers

Charging modules, power supplies, power boards and test equipment companies

Test and assembly objects

Plugs and sockets, load and temperature measuring points

Development and delivery

Simultaneously record current, voltage drop and temperature, output connection status and temperature rise process

Project input

Reference electrical measuring instruments, wiring contacts, excitation range and temperature conditions

Acceptance method

Fixed contact installation, loading current and environment, check voltage drop/four-wire resistance and temperature measurement points; record the basis for reaching steady state and the difference in repeated plugging.

Implementation steps

Object and interface verification → Reference link and solution confirmation → Single module prototype → Instrument and equipment joint debugging → Independent reference re-inspection → Source code, configuration and record delivery.

Equipment condition and scope confirmation

The scope may include control boards, firmware, instrument drivers, host software, process configuration and test records. Mechanical fixtures, pressure-bearing structures, fluid circuits, power circuits and optical or acoustic references are provided or separately designed by the responsible parties. Measurement specifications are established through validation with the target equipment and independent references.

Source code, design documents, instrument licensing, procurement, on-site support and ongoing maintenance scope are listed in the project documents.
