450V-750V HV PTC Air Heater Defroster for Electric Bus
Electric Bus Defroster Description
1、 Product Definition
Chinese name: 450V-750V High Voltage PTC Wind Heating Defroster Applicable objects: Pure electric/hybrid/fuel cell new energy buses, coaches, buses Type: High voltage direct blowing and heating type, no need for antifreeze pipelines, no need for external high-pressure water pumps, high voltage electricity directly heats the air, integrating front windshield defrosting and defogging+cabin heating.
2、 Core working principle
Suitable for high-voltage platform DC 450V-750V power supply of the entire vehicle;
Built in high-voltage PTC ceramic heating element can quickly generate heat when powered on, with self limiting temperature that does not exceed the limit and no open flames;
The centrifugal fan forces the flow of air, and the cold air passes through the PTC core and directly becomes hot air;
Directed hot air blows towards the front windshield and side windows, quickly defrosting, defogging, and defrosting;
At the same time, it can provide heating for the cockpit, with one machine for dual use;
Equipped with high-voltage insulation, HVIL high-voltage interlock, and multiple protections for overvoltage/undervoltage/overtemperature/locked rotor.
3、 Main technical parameters
High voltage working voltage: DC 450V~750V (suitable for mainstream high voltage platforms of passenger cars 600V)
Control voltage: DC 24V
Heating power: 6kW/8kW/10kW/12kW optional
Heating method: HV PTC ceramic air heating direct heating type
Communication protocol: CAN2.0/SAE J1939
Protection level: IP65/IP67
Working environment: -40 ℃~+85 ℃, suitable for high cold areas
Structural form: Integrated wind and heating, waterless pipeline design
4、 Core advantages of the product
Wide voltage adaptation: 450-750V full range compatibility, compatible with all new energy bus high-voltage platforms;
Wind heating without water circuit: no need to connect antifreeze, no need to equip high-pressure water pump, simple installation, maintenance free, low failure rate;
PTC safety constant temperature: self limiting temperature characteristics, no redness, no open flame, anti dry burning, safer than resistance wire heaters;
Defrosting and heating two in one: front defrosting and cabin heating integrated, saving space for vehicle layout;
High voltage safety design: high voltage isolation insulation, HVIL high voltage interlock, meeting commercial vehicle high voltage safety regulations;
Low noise and seismic resistance: car specific fan, seismic and anti-corrosion resistant, suitable for the bumpy chassis environment of passenger cars;
Fast heating: Hot air comes out immediately upon startup, and defrosting and defogging quickly in low-temperature environments.
5、 Application scenarios
New energy city buses, passenger buses, tourist buses, school buses, hybrid buses, hydrogen fuel buses are the preferred choice for vehicles in northern high-altitude regions.
