Comparative Analysis of Application of HVCH and PTC Heaters to New Energy Buses
WANG Haitao
Abstract: The high-voltage coolant heater(HVCH)and positive temperature coefficient(PTC)heater are the two types of high-voltage heaters widely used in new energy buses.The author finds that each has its characteristics in terns of structure,performance,economy,and applicability through comparative analysis,while the HVCH is superior to PTC in energy management.
