From test method to product

Six test methods across the product portfolio

Observation, simulation or analysis – the method follows your test. Each product brings the physical interfaces and released functions for your DUT (device under test) and configuration.

Configure
Make test intent explicit

DUT role, interfaces, parameters, automation and results are defined before the hardware is chosen.

Explore comframe
Simulate
Control counterpart behaviour

Nominal, boundary and non-conform behaviour are tested within the released product and protocol scope.

Professional Simulation
Measure
Keep physical and protocol layers together

Communication, low-level signals, power and application states share one time base.

Explore EVCA
Analyse
Connect observation and expectation

Released evaluation functions compare measured behaviour with the applicable technical rules.

Automated Standards Analysis
Validate
Repeat an approved test method

Versioned test logic and controlled configurations give each verdict a defined scope.

Conformance Test Libraries
Preserve records
Keep result and configuration attributable

Test identifiers, measurements, decisions and reports stay together for development, release or production.

Charge Cycle Automation

The product for your DUT

Apply the method to your test environment

Product, interface and control model follow your DUT. The required capabilities are confirmed for the selected configuration.

EV and EVSE development
EVCA + comframe

Analyses communication, simulates partners, measures responses, applies controlled faults and tests interoperability with released test logic.
