Batteries generate heat during charging and discharging. Excessive temperature will reduce battery performance and shorten its life. Battery cold plates effectively conduct and dissipate heat to the external environment by contacting the battery surface to keep the battery within a suitable temperature range.
b. Material selection
Battery cold plates usually use materials with excellent thermal conductivity, such as aluminum, copper or composite materials with high thermal conductivity, to ensure effective heat conduction and heat dissipation.
2. Advantages of battery cold plate
a. Improve performance
Through effective heat management, battery cold plates can improve the working efficiency of the battery and reduce the impact of temperature rise on battery performance, thereby increasing the energy density and power output of the battery.
b. Extend life
Good heat dissipation design can reduce the operating temperature of the battery, reduce the damage to battery materials caused by thermal stress, and extend the service life of the battery.
c. Improve security
Effective thermal management can reduce the risk of battery overheating, reduce the possibility of fire or explosion, and improve battery safety.
3. Application of battery cold plate in battery field
a. Electric vehicles
In electric vehicles, the battery cold plate plays a key role in ensuring that the battery maintains good working condition under long-term high-load operation, thus extending the service life of the battery and the vehicle.
b. Portable devices
In portable devices such as smartphones and tablets, battery cold plates can provide stable heat dissipation performance and avoid the impact of overheating on device performance and safety.
c. Renewable energy systems
In solar and wind energy storage systems, battery cold plates can ensure good thermal management of batteries during charging and discharging, improving energy conversion efficiency and system stability.
Battery cold plate technology plays a key role in improving battery performance, extending life and improving safety.
