New Energy Cooling Plates for Battery Thermal Management Systems

New Energy Cooling Plates for Battery Thermal Management Systems

New Energy Cooling Plates are a key component of battery thermal management systems. They remove heat generated by the battery cells through physical contact and liquid circulation, maintaining the battery within an optimal temperature range to maintain performance, extend life, and improve safety. In the new energy vehicle sector, liquid cooling plates are gradually replacing air cooling technology as the mainstream due to their efficiency and reliability.

Functions and Uses

Heat Dissipation: The cooling plate directly contacts the battery cells, dissipating heat generated during battery operation through flowing coolant.

Temperature Control: Ensures the battery pack remains within the optimal operating temperature range, thereby improving charge and discharge efficiency.

Extending Life and Improving Safety: Prevents battery overheating, slows battery aging, prevents problems such as bulging, and improves overall battery life and safety.

Optimizing Performance: Maintains consistent performance across battery cells and reduces temperature variations, thereby optimizing the performance of the entire battery pack.

Main Types

Liquid Cold Plates: Rely on coolant circulating through internal channels to dissipate heat and are currently the mainstream technology in new energy vehicles.

Passive Cold Plates: Rely primarily on the thermal conductivity of the material itself to dissipate heat. Other Advanced Technologies: These include the use of thermoelectric materials to convert heat into electricity to improve energy efficiency, as well as heat pipe cooling.

Design Requirements

Temperature Uniformity: The temperature throughout the battery pack should be as uniform as possible.

Low Contact Thermal Resistance: The contact thermal resistance between the battery and the cold plate should be as low as possible.

Flow Rate Uniformity: The coolant flow rate within the cold plate should be uniform.

Sealing and Lightweight: The cold plate must be reliably sealed while also meeting lightweight requirements.

Market Applications

New Energy Vehicles: This is currently the primary application for liquid cold plates.

Energy Storage: They are also widely used in stationary energy storage systems, requiring high durability and long-term stability.
