20kw Electric Bus PTC High Voltage Heater

The future of mobility is electric. Renewable energy sources allow for carbon-reduced mobility. Anew generation of vehicles is emerging--E-cars and hybrid.

Increased electric vehicle rang results in less engine heat and thus to higher heating requirements.

The 20kw high voltage coolant heater is mainly used for heating the passenger compartment ,defrosting and removing fog on the window,or preheating battery thermal management system battery ,to meet the corresponding regulations, functional requirements.

20kw Electric Bus PTC High Voltage Heater

1.Product description

New energy pure electric vehicles, without an engine, cannot use the waste engine heat as a warm air conditioning heat source, and at the same time need to heat the battery pack at low temperatures to improve the low temperature range, so new energy vehicles use PTC heaters to provide a heat source for the interior air conditioning system and battery heating system, and their overall structure consists of a radiator (including PTC heating pack), coolant flow channel, main control board, high voltage connector, low voltage connector and upper housing. It is part of the thermal management system of the new energy vehicle.
