3,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:

      Over (under) voltage protection

      Short circuit protection (current-limiting fuse in distribution box)

      Leakage protection

      Interlock response

(6) High voltage electric heater must be equipped with 30A 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.

 

4,Product Installation

 

The PTC electric heater module consists of PTC heating components, controllers and internal pipelines. The heating component is installed in the aluminum die casting, the aluminum die casting and the plastic casing form a closed circulation pipeline, and the cooling liquid flows through the heating body in a meander structure.
