EV and hybrid manufacturers are searching for every
yard/meter of range they can squeeze out of their vehicles. In the race to get
their newest offerings into the driveways of consumers, range is a major
factor. HVAC can severely effect vehicle range, and engineers are doing
everything possible to reduce the impact of this creature comfort/necessity.
We will explore electric compressor design, 3-phase motor
operation, and electronic compressor control. Testing a HIGH VOLTAGE (HV)
electric compressor requires PPE, specific equipment, and procedures; both will
be discussed and safely demonstrated.
Heat pump system theory, design, components, and operation
will be discussed and demonstrated in heating and cooling modes using
temperature and pressure analysis. Thermal management systems which usually
incorporate an electric compressor and heat pump, will be fully explained.
