In the development process of new energy car, range and charging efficiency have always been the focus of users' attention. However, the low-temperature environment has become a "blocker" for improving battery performance. When the temperature drops sharply, the chemical reaction inside the battery slows down, resulting in a decrease in battery capacity and a significant reduction in range. A car that could easily travel 300 kilometers might only be able to cover half the distance in the cold winter. This is a very troublesome problem. At the same time, the low temperature also slows down the charging speed of the battery, extending from the original 1 hour to 3 - 4 hours, greatly reducing the convenience of use.
In the face of this predicament, the most direct solution is to "heat up" the battery. However, the batteries of new energy car are large in size, and it is not an easy task to heat them from a low-temperature environment to an appropriate temperature. This requires the heater to have the ability to quickly heat up and efficient heat transfer, while also considering the temperature increase rate that the battery can withstand, the stable output of the thermal management system, and the waiting time for users. Under such high requirements, thick-film heating technology stands out and becomes the "warming winter tool" to break the "cold spell curse".
The thick-film heating plate adopts advanced thick-film printing technology, with its heating speed reaching 80 - 150℃/s. It can generate a large amount of heat in a short period of time. The heating efficiency is even over 96%, which is more than 20% more energy-efficient compared to traditional heating methods. This high-performance heating capability enables it to transfer heat to all parts of the battery more quickly and evenly, causing the interior temperature to rise rapidly and enhancing driving comfort. Whether it is starting the vehicle in a cold morning or encountering low-temperature conditions during long-distance driving, the thick-film heating plate can quickly take effect, creating a warm and comfortable driving environment for users.
