Here's how a polyimide heater for a lithium battery in a new energy vehicle typically works:
Polyimide Heater: The heating element is constructed using a thin and flexible polyimide substrate. A resistive heating element is embedded or printed onto this substrate. Polyimide is chosen for its lightweight, flexibility, and thermal stability.
Integration: The polyimide heater is strategically integrated into the battery pack of the electric vehicle, positioned close to the battery cells or modules. The heater should be designed to distribute heat evenly across the battery pack.
Temperature Control: The heater is connected to a control system that monitors the temperature of the battery pack. This control system can include temperature sensors that detect the temperature of the battery cells.
Cold Weather Operation: In cold weather conditions, lithium-ion batteries can experience reduced performance and efficiency. Cold temperatures can lead to increased internal resistance and reduced energy output. The polyimide heater is activated when the battery temperature drops below a certain threshold, helping to keep the battery within an optimal operating temperature range.
Preventing Cold Soak: Cold soak conditions occur when a vehicle is parked in cold weather, and the battery's temperature drops significantly. The polyimide heater can be used to "pre-heat" the battery before starting the vehicle, improving the battery's efficiency and extending its lifespan.
Safety and Efficiency: Maintaining lithium-ion batteries within their optimal temperature range improves their safety and extends their longevity. Overheating is prevented through proper temperature control.
Integration with BMS: The Battery Management System (BMS) of the vehicle communicates with the heater control system to ensure seamless operation. BMS also monitors other battery parameters like state of charge and state of health.
Polyimide heaters for lithium batteries in new energy vehicles are crucial for optimizing battery performance, especially in regions with cold climates. They contribute to the efficiency, safety, and reliability of electric and hybrid vehicles, ensuring that the batteries can deliver the required power output regardless of external temperatures.
