Description
7kw High Voltage Coolant Heater for commercial vehicles
Products Description
High-voltage coolant heater
The main application field of the PTC coolant heater is pure electric/hybrid/fuel cell vehicle heating systems. The specification of the PTC coolant heater is used to describe the performance and related characteristics of the heater, as well as the control and verification of the main heat source for the interior temperature regulation.
The PTC coolant heater assists in battery temperature regulation for hybrid and electric vehicles and fuel cell vehicle startup. The requirements for these special safety features (such as overheated batteries) are controlled by the vehicle's main control system.
PTC coolant heater PTC technology can meet the high safety requirements of high-voltage components in passenger vehicles. In addition, the PTC coolant heater is designed as a component of a thermal management system that meets environmental requirements. Refer to the high voltage specifications and standards in the development and design, such as GBT 31466-2015, electric vehicle high voltage system grade.

Function list
Heating gear stepless control mode
The gear can be adjusted steplessly through the PWM control method, and the power control can be controlled from 0 to 100% in the form of a percentage.
Heating temperature control mode
In the temperature control mode, the heating is performed with 100% power, and the heating is stopped when the "heating temperature setting value" is reached, and the heating is started only when the body heating request is received again.
CAN communication
Support CAN2.0B(SAEJ1939)communication: CSAE43-2015;
Baud rate：250kbit/s(according to customer requirements)
Cycle time：1000ms(according to customer requirements)
Products Design
Design
The whole PTC water heater is composed of an aluminum die-cast shell, a PTC heating module assembled inside the shell, and an electronic unit control panel, which has a compact structure and good vibration resistance.
CAN bus is used to exchange data and control instructions with the upper computer.
Through the metal cover and seal ring match, so that the sealing is good.
The cooling water channel is designed as a "Z" surround channel with a large heating area and high heating efficiency.
The internal use of PWM control PTC heating, heating precision, can effectively improve the thermal efficiency.

Products FAQ
FAQ
Q: How Does the Heater Support Battery Thermal Management in EVs?
A:
✅ Battery Temperature Optimization: EV battery packs operate best between 20-40°C. A PTC water heater is essential for pre-conditioning batteries in cold climates, reducing charge time and improving range.
✅ Integration with Cooling Loops: The heater works in conjunction with electronic water pumps, ensuring uniform heat distribution to prevent localized overheating or cooling inefficiencies.
✅ Smart Thermal Cycling: Some systems allow the heater to cycle on/off based on battery demand, ensuring optimal energy use without unnecessary heat generation.
Q: What Are the Power Consumption and Efficiency Metrics?
A:
✅ Dynamic Power Adjustment: The PTC heater automatically adjusts power draw based on real-time temperature demand, improving energy efficiency and preventing unnecessary power drain.
✅ Energy-Efficient Heating: Compared to traditional electric resistance heaters, PTC technology consumes up to 30% less energy, making it more sustainable for EV applications.
Q: What is the Life Expectancy of the PTC Heater?
A:
✅ Durability & Longevity: PTC elements do not suffer from wear and tear like traditional heating coils, providing a longer service life (10+ years in normal operation conditions).
✅ Resistance to Voltage Fluctuations: Unlike resistance heaters that degrade over time due to thermal stress, PTC materials have a self-regulating nature, preventing electrical fatigue and prolonging operational life.
