Application
1. Low-Temperature Preheating and Temperature Control of Power Batteries (Core Application)
New energy power batteries are extremely sensitive to operating temperature. Low temperatures can easily lead to reduced range, lithium plating during charging, and decreased charge/discharge efficiency. Thick-film high-voltage heaters, by heating the circulating coolant, can quickly raise the temperature of the battery module and stabilize it within the optimal operating range of 25-35℃, achieving low-temperature preheating and constant temperature control during vehicle operation. This effectively improves fast charging speed in winter, reduces battery degradation, avoids safety hazards, and ensures battery charge/discharge performance and lifespan. It is widely used in battery thermal management systems for pure electric and plug-in hybrid vehicles.
2. Vehicle Passenger Cabin Heating
Electric vehicles lack engine waste heat for heating. Thick film high voltage coolant heater are one of the core heating heat sources. By heating the vehicle's coolant, warm air is blown out through the air conditioning heater core, providing stable heating for the passenger cabin.
3. Suitable for Multi-Component Thermal Management: In extremely cold conditions, it can serve as an auxiliary primary heat source for heat pump air conditioners, compensating for the insufficient low-temperature heating capacity of heat pumps and addressing the issues of slow and inadequate heating in vehicles during winter. It meets the cabin comfort and temperature control requirements of passenger cars and commercial new energy vehicles.
4. Adaptable to All Types of New Energy Vehicles:It is adaptable to all thermal management scenarios in new energy vehicles, providing low-temperature preheating and constant-temperature insulation services for high-voltage electrical components such as motors, electronic controls, and on-board chargers. This prevents reduced efficiency and load limitations of high-voltage components under low-temperature conditions, ensuring stable operation of the vehicle's three-electric system across the entire temperature range and improving the vehicle's adaptability to all operating conditions.
5. Suitable for All Types of New Energy Vehicles:The product boasts strong compatibility, fully adapting to pure electric BEVs, plug-in hybrid PHEVs, and range-extended electric EREVs. It can also be widely applied to electric buses, electric trucks, and special-purpose new energy commercial vehicles. It is particularly compatible with new models using 800V high-voltage fast-charging platforms and is a mainstream standard thermal management core component for current high-end new energy vehicles and next-generation high-voltage platform models.
