Hybrid and pure electric vehicles are increasingly favored by the market, but the performance of power batteries of some models is not satisfactory. OEMs often overlook a problem: At present, many new energy vehicles are only equipped with battery cooling systems, while ignoring the heating system. At low temperature, the lithium ion activity of the power battery will be greatly reduced, and the viscosity of the electrolyte will increase sharply, resulting in a significant decline in battery performance and directly affecting the service life of the battery.
NF has been committed to providing clean and efficient drive system solutions for internal combustion engines, hybrid and electric vehicles, and has launched a rich product portfolio in the field of thermal management. Considering the importance of the car battery pack heating solution in the post-internal combustion engine era, NF has launched a new high voltage coolant heater (HVCH) in response to the above pain points. What technical highlights are hidden in it, let us uncover its mystery.
Breaking away from the era of internal combustion engines, HVCH solves two major pain point.
It can not only keep the cabin warm without the heat of the engine, but also regulate the temperature of the power battery pack to ensure its high efficiency operation. These are the two pain points of thermal management in hybrid and electric vehicles. NF addresses these issues with the High Voltage Ptc Heaters
Two years ago, the automotive thermal management system has gradually be separated from the internal combustion engine, and most hybrid vehicles will be separated from the heat of the internal combustion engine until it is completely separated in pure electric vehicles. Therefore, NF developed a High Voltage Electric Liquid Heater to meet the thermal management needs of high-performance systems that rapidly generate heat in new energy vehicles. At present, NF has received large-scale orders for high voltage coolant heaters from a leading European automaker and a major Asian automaker, and production has began in 2020.
In addition, for different models Car, HVCH has different specifications, the power range is 2.26 KW to 30 KW, and the applicable power supply voltage is 180 volts to 800 volts. To prevent the device from overheating, the system automatically shuts down in the event of a malfunction.keep machines safe.
Highlights of HVCH
Ultra-compact design with increased service life: The new high voltage coolant heater adopts an ultra-compact modular design with high thermal power density. The weight reduction in pack size and overall mass also allows for better durability and longer life, with the rear membrane heating elements rated to last 15,000 hours or more.
