8KW PTC Technology Heater
Hebei Nanfeng Group has been producing heaters for more than 30 years, and our company is the largest manufacturer of automobile heating and cooling equipment in China and the designated supplier of military vehicles in China.8KW PTC technology heater is specially designed for electric vehicles and has the advantages of fast heating and environmental protection.
Description
8KW PTC Technology Heater
Products Description
Necessary conditions for heater:
- The heater is controlled by CAN communication
- High voltage power supply
- Low voltage power supply (BATT) or Kl15 (ignition switch voltage), Kl31 (GND)
- The heater needs to set a high voltage interlock circuit
- The whole vehicle must have an insulation monitoring device to monitor:
o Over (under) voltage protection
o Short circuit protection (fuse in the distribution box)
o Leakage protection
o Interlock response
- The high voltage electric heater must be equipped with a 40A fuse
- It must be ensured that the high voltage power supply has no reverse polarity
- The whole vehicle needs to be powered off when overvoltage occurs
- The high voltage input should be pre-charged
- 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

Power-on check
Only high voltage can be operated without limiting the performance of the heater.
After turning on or resetting the heater, the heater waits for a power request on the CAN bus. Once a valid power request is received, the power-on check starts.
First, the total current is checked when all heating circuits of the heater are not activated. If it exceeds a predetermined value, the heater is not working at this time, so this fault indicates a short circuit, leakage current or open circuit fault.
