5kw DC350V 12V CAN WPTC Coolant Heater For EVs
Description
Our EV PTC heater, also known as electric coolant heater or EV battery heater, is the core heating component for electric vehicle BTMS and cabin heating systems, widely adopted in passenger EVs, electric commercial trucks, buses and fuel cell vehicles.
Built with self-regulating PTC ceramic elements, this electric coolant heater heats coolant efficiently to maintain lithium-ion batteries within the optimal working temperature range in cold climates. As a high-performance EV battery heater, it realizes fast battery preheating, reduces internal resistance, protects battery health, improves charging speed and extends driving range in low-temperature environments. Meanwhile, it supplies stable heat for cabin warming, defrosting and defogging, balancing thermal comfort and energy consumption.
Featuring inherent over-temperature limitation, no open flame, high safety, high thermal efficiency and compact structure, our EV PTC heater supports CAN/LIN communication, precise temperature closed-loop control, multiple voltage and power options for flexible integration. IP67 protection grade, vibration resistance and long service life make it a trusted heating solution for EV OEMs and system integrators worldwide.
Count on our EV battery heater and electric coolant heater to stabilize your vehicle thermal performance, even under extreme cold conditions.
