PTC battery pre heating is a configuration used for new energy vehicles or energy storage, especially for pure electric vehicles. It is a technology to improve the battery temperature as soon as possible and enable it to enter the optimal operating temperature. At present, both Lithium iron phosphate battery and ternary lithium battery will be affected by the reduction of the activity of positive and negative electrode materials and the conductivity of electrolyte in low temperature environment. The charging time will correspondingly increase, and the battery will be more difficult to fully charge. During use, the power battery pack will experience a significant acceleration in its "power down" speed. Therefore, in order to solve the above problems, Shenzhen Tianxiangyu has developed a battery preheating system and a thermal management system. Adjust the temperature of the battery pack through PTC heaters or pipeline heaters to reduce the impact of environmental temperature on it.
