Every request for quotation (RFQ) we receive for braking resistors contains two key values: the DC bus voltage and the braking power.…

Review HVCH coolant compatibility before release: exact fluid, additives, conductivity, materials and fill controls for electric bus and truck heating circuits.

Review BTMS condenser airflow, hot-air recirculation and vehicle-bay restrictions before freezing an electric bus or truck installation. Prepare the right evidence.

Bei der Festlegung der Spezifikationen für Bremswiderstände kommt es entscheidend auf drei Werte an. Sind diese drei Werte korrekt, lässt sich der…

Verify HVCH power by separating requested output, electrical input and coolant-side heat transfer, with clear boundaries and project-specific acceptance criteria.

Separate measurement issues, coolant distribution and cooling capacity when investigating uneven battery temperatures in electric buses and trucks.

Define repeatable warm-up response evidence for an HVCH without confusing heater output, coolant temperature and vehicle readiness.

Define filling, circulation and acceptance evidence for liquid-cooled battery thermal management systems before thermal performance testing.

Review compressor water-temperature control, expansion-valve superheat control and condenser-fan pressure calibration for commercial EVs.
