Functions
PTC water heater can provide heat for the cockpit of new energy vehicles and meet the standard of safe defrosting and defogging. It also provides heat to other parts of the vehicle that require temperature regulation, such as the battery.
The electric High Voltage Heater (HVH) is the ideal heating system for plug-in hybrids (PHEV) and battery electric vehicles (BEV). It converts DC electric power into heat with practically no losses.
Powerful similar to its namesake, this high-voltage heater is specialized for electric vehicles. By converting electrical energy of battery with DC voltage, ranging from 300 to 750v, into abundant heat, this device provides efficient, zero-emission warming-all throughout the interior of the vehicle.
Features
Features Electricity is used to heat the antifreeze，and the heater is used to heat the interior of the car. Installed in the water cooling circulation system Warm air soft temperature controllable Adopt PWM to adjust and drive IGBT to adjust power With short-term heat storage function Vehicle cycle, support battery thermal management Environmental protection.
Air conditioner control framework
1.Complete the command input from the air conditioning panel.
2.The air conditioner panel sends the user's operation command to the controller through CAN communication or ON/OFF PWM.
3.After the water heating PTC controller receives the command signal, it turns on the PTC in PWM mode according to the power requirement.
Design advantages：
1.Using 4-channel PWM control mode, the busbar inrush current is small, and the requirements for the relay in the vehicle circuit are low.
2.PWM mode control enables continuous adjustment of power.
3.The CAN communication mode can report the working status of the controller, which is convenient for vehicle control and monitoring.
