Description
24KW Electric Vehicle PTC Coolant Heater
Products Description
Introducing the Electric Bus Heater-a revolutionary device that heats buses in an energy-efficient way and delivers warm and comfortable rides to passengers in cold weather. The PTC Coolant Heater is an innovative heating system that converts electricity into heat energy, providing a reliable and safe source of warmth to buses. Its user-friendly interface and easy-to-use control system allow drivers to adjust the temperature to the desired level and maintain a comfortable environment for passengers.
One of the prime benefits of the High Voltage Coolant Heater is its energy efficiency. When compared to traditional heating systems, it consumes less energy and, consequently, reduces operational costs. This makes it an excellent choice for fleet owners who want to save money without sacrificing passenger comfort.
Moreover, the EV Heater is designed to deliver uniform and consistent heating performance. It works on the principle of convection, where it warms up the air inside the bus and distributes it evenly throughout the cabin. This means no more hot or cold spots and happy passengers throughout the journey. Safety is always a top priority, and the New Energy Bus Heater ensures it by incorporating advanced safety features. It comes with automatic shut-off and overheat protection systems that prevent overheating and potential fire hazards. Also, its compact size and easy installation make it a perfect choice for retrofitting old buses or fitting new ones.
In conclusion, the High Voltage PTC Heater is a reliable and efficient heating system that transforms the experience of riding a bus in cold weather. With its energy efficiency, uniform performance, and safety features, it is an ideal choice for fleet owners who want to provide their passengers with a comfortable and safe ride, all while reducing operational costs.

Note: There is no coolant flowing in the heater, and the heater will enter the high-temperature protection state. When the coolant is not drained properly, it will affect the heating capacity of the heater and the accuracy of the temperature collection of the water outlet. The long-term operation will reduce the reliability of the heater.
Necessary conditions for heater
(1) The heater is controlled by CAN communication
(2) High voltage power supply
(3) Low voltage power supply (BATT) or Kl15 (ignition switch voltage), Kl31 (GND)
(4) The heater needs to set a high-voltage interlock circuit
(5) The vehicle must be equipped with an insulation monitoring device to monitor:
a. Over (under) voltage protection
b. Short circuit protection (current-limiting fuse in distribution box)
c. Leakage protection
d. Interlock response
(6) High voltage electric heater must be equipped with an 80A current-limiting fuse
(7) It must be ensured that the high-voltage power supply has no reverse polarity
(8) The vehicle needs to be powered off when overvoltage occurs
(9) High voltage input should be precharged
(10) The high voltage input should be equipped with a relay, when a serious fault occurs, the high voltage can be cut off without affecting the safety of the whole vehicle.
