Core advantages (compared to traditional fuel vehicles with water heating defrosting and low-pressure defrosting)

1. Compared to traditional engine water heating defrosting (fuel powered buses)

No engine dependency

Pure electric vehicles have no engine waste heat, and high-pressure defrosting is the only independent heating solution; The vehicle can defrost normally during idle, parking charging, and standby. In winter, the defrosting during parking at the station is not limited by engine start stop.

Extremely fast startup speed

Fuel powered cars need to heat up for 3-5 minutes before there is hot air; High voltage PTC produces high-temperature hot air within 30 seconds of startup, increasing defrosting efficiency by more than 4 times during cold start.

Simple system structure and low failure rate

Dry type models have no hidden dangers of engine water pipes, thermostats, warm air water valves, and antifreeze leakage, with fewer pipelines and simple maintenance;

Uniform temperature control without damaging the glass

PTC automatic constant temperature, with a fluctuation of hot air temperature difference of less than or equal to plus-minus 2 , to avoid the risk of windshield cracking caused by traditional engine sudden cold and hot changes.

2. Compare low-voltage 24V resistance wire defrosting

High heating power and defrosting efficiency

The power upper limit of low-voltage models is only 2-3kW, and large buses have weak defrosting capabilities; High voltage models can reach 10-30kW and are suitable for large-area front windshields of 12 meter and 18 meter articulated buses.

Lower energy consumption and higher heating efficiency

PTC electric thermal conversion efficiency>95%, ineffective heating without resistance wire; Under the same heating capacity, the high-voltage line current is smaller, the harness loss is lower, and the winter power consumption of the whole vehicle is reduced by 20% -30%.

Significant increase in security level

PTC self limiting temperature never turns red, eliminating the risk of resistance wire overheating and fire;

Standard HVIL high voltage interlock, insulation monitoring, multi-stage overheating fuse, IP67 waterproof and dustproof;

Double independent temperature protection, forced power-off when the fan stops running, and far superior anti dry burning performance compared to resistive type.

3. Comprehensive advantages of the product itself

Energy saving and energy-saving, extending winter battery life

Intelligent segmented power regulation, no need for continuous operation at full power; Cycling in high-altitude regions can save thousands of kilowatt hours of electricity per month in winter.

Long service life and resistance to harsh working conditions

PTC ceramics have no oxidation or erosion issues, with an average MTBF time between failures exceeding 12000 hours; The anti-corrosion of the shell has passed the 720 hour neutral salt spray test and is suitable for high humidity salt spray environments in northern ice and snow, coastal areas.

Flexible installation and high integration

Dry independent box can be arranged on both sides of the instrument panel and inside the air duct; The water heating model can integrate a vehicle thermal management module, adapt to various types of bus chassis, and support customization of multiple air outlet ducts.

Environmentally friendly, reliable, no combustion, no exhaust, no risk of fuel leakage, zero emissions; No open flames, it is safer to use in a closed environment at bus stops.

Intelligent adaptation to vehicle standard CAN2.0 communication, compatible with mainstream bus controllers, supports remote monitoring of defrosting status and fault reporting for fleets, and is compatible with intelligent buses and autonomous driving buses.

Applicable vehicle models

6-18 meter pure electric city buses, tourist buses, commuter buses, hybrid buses, fuel cell buses, especially mandatory standard for operating vehicles in the high-altitude regions of Northeast and Northwest China.
