PTC Electric Heater For EV

 

 

The 3kW PTC coolant heater is a core component of thermal management systems for new energy commercial vehicles and RVs; it utilizes PTC ceramic semiconductor technology to heat coolant circulating within the vehicle's fluid loop, rather than heating the air directly.

 

 

Power (KW)	3KW
Rated voltage(V)	350V
Supply voltage (V)	260-420V
Flow rate (L/h)	12 (±1)L/min
Baud rate	250K
Working temperature	-40℃~85℃
Storage temperature	-40℃~85℃
Control	CAN

 

Core Structure:

  PTC ceramic heating element (core heating component)

  Aluminum alloy water-cooled heat exchange chamber (coolant flow channels)

  High-voltage drive control board (MCU + IGBT power components)

  High-voltage connector, low-voltage control connector, and inlet/outlet ports

  Multiple temperature, current, and pressure sensors

 

 

-- Safe and reliable with self-limiting temperature and dry-burn protection: The PTC ceramic element does not glow red; power output automatically drops during water shortage or insufficient flow, complemented by software-based multi-level protections against over-temperature, over-current, over-voltage, under-voltage, and short circuits; features water-electricity isolation and high insulation standards.

-- High thermal efficiency: Thermal efficiency ≥95%; rapid heating upon activation with no high inrush current.

-- Controllable power: Supports stepless adjustment via vehicle CAN signals, delivering heat on demand to reduce battery energy consumption and extend driving range.

-- Vibration-resistant and durable: Eliminates issues with oxidation or burnout of resistance wires; suitable for the rugged operating conditions of commercial vehicles, with minimal power degradation.

-- Integrated design: Heating and drive control units are housed in a single casing for easy installation; connects directly in series with the cooling circuit.

 

 

 

PTC electric heaters can be used in vehicles such as new energy trucks, light-duty trucks, buses, RVs, and construction machinery to provide cabin heating and windshield defrosting and defogging functions.

 

 

The PTC electric heaters have obtained professional CE certification; the CE certificate is shown in the image below. Certain models have undergone professional EMC testing, and test reports are available upon request.
