In-Cabin Sonic Stress-Relief System
With the rise of new-energy vehicles and demand for a healthier in-vehicle lifestyle, automakers increasingly focus on comfortable and relaxing mobility experiences. The in-cabin sonic stress-relief system provides wellness support for professional drivers, long-distance drivers, family trips, and young consumers who pursue technology and quality of life. Sonic massage helps promote blood circulation and relieve long-distance driving fatigue. It can synchronize with movie soundtracks for an immersive 4D cinema experience and, during breaks or waiting periods, work with cabin fragrance and air conditioning to guide occupants quickly into a nap state through deep-relaxation frequencies.

Long-Distance Escort Mode

During highway cruising, gentle wave-style massage helps promote blood circulation and relieve fatigue.

Immersive Audio-Visual Mode

During parked rest or charging, massage rhythm synchronizes with movie audio to deliver a 4D cinema experience.

Comfort Rest Mode

During lunch breaks or waiting, deep relaxation frequencies work with cabin fragrance and air conditioning to help occupants enter a nap state.

Vehicle / Energy Storage Liquid Cooling Unit
Liquid cooling units serve as core thermal management equipment for new energy vehicles. Compared with air cooling systems, they deliver superior heat dissipation efficiency and precise temperature control, supporting both heating and cooling regulation. Compatible with 4C–8C ultra-fast charging, the units feature low noise, high integration, low power consumption and extended service life, and can operate stably across a wide temperature range of -45℃ to +60℃.Widely deployed on new energy commercial vehicles including buses, heavy-duty trucks, and special vehicles for mining and port operations, this equipment fits full-spectrum scenarios: daily commuting, high-speed ultra-fast charging, high-frequency commercial transportation, extreme weather conditions, special operations, as well as vehicle-mounted and energy-storage external power discharge applications.

High-Temperature Rapid Cooling

When battery temperature is high, rapid cooling helps avoid and delay fire or explosion risks caused by high cell temperature and delayed thermal diffusion during charging, preventing thermal runaway events.

Low-Temperature Rapid Heating

When battery temperature is low, preheating raises battery temperature to meet charging, discharging, and safety requirements in low-temperature environments, reducing winter range anxiety.

Self-Circulating Multi-Closed-Loop Control

Real-time battery data and latest battery status enable the control system to automatically select operating modes: shutdown, cooling, heating, and self-circulation.

Water PTC Heater
The high-precision ceramic chip water PTC heater is mainly used in new-energy passenger and commercial vehicle cabin heating, low-temperature power-battery preheating, and energy-storage container temperature control. It uses barium-titanate-based ceramic heating elements and features low-temperature rapid heating, self-circulating closed-loop control, and a water-electricity separation safety design. Thermal conversion efficiency reaches 98%, energy efficiency improves by 15%, battery range can be extended by 8%-12%, and the product is compatible with 800V high-voltage platforms. It is a key solution for winter range degradation in new-energy vehicles.

Low-Temperature Rapid Heating

Preheats the battery when temperature is low to improve charging/discharging performance and safety in winter conditions.

Self-Circulating Closed-Loop Control

Real-time water temperature and pipeline flow monitoring dynamically adjusts PTC heating power to maintain precise constant temperature and avoid overheating and dry burning.

Water-Electricity Separation Safety Design

The heating ceramic and waterway cavity are physically separated; live components do not directly contact coolant, preventing leakage and short circuit risks.

Air PTC Heater
The air PTC heater is mainly used for new-energy passenger and commercial vehicle cabin heating and windshield defrosting/defogging. Based on high-performance ceramic heating elements, it provides ultra-fast heating in low-temperature environments with high thermal efficiency and rapid response. A self-circulating closed-loop intelligent control system dynamically adjusts heating power in real time to ensure safe, stable operation. Its compact modular structure adapts to different vehicle installation layouts and improves winter cabin comfort.

Low-Temperature Rapid Heating

The ceramic heating element can quickly conduct power at -30℃ and produce hot air within 30 seconds, supporting winter heating and windshield defrosting/defogging.

Self-Circulating Closed-Loop Control

High-precision sensors and intelligent algorithms monitor inlet/outlet air temperature and dynamically adjust power for constant-temperature control.

Compact Modular Design

Stacked integrated architecture combines heating elements and air guide ducts, reducing volume by more than 20% compared with competing products and saving installation space.
