Cooling plate battery cabinet system

Battery cold plates are typically classified into two main types based on the cooling method: Liquid Cooling Systems and Direct Refrigerant Cooling Systems. Liquid cooling systems use a water-glycol mixture or similar coolant that circulates through internal channels in the cold plate to absorb and transfer heat away from the battery cells.

A battery cooling plate is a flat component manufactured from thermally conductive materials like aluminum or copper. Its function efficiently removes excess heat generated during the battery's fast charging and discharging processes. Two simple schemes will show what is a cold plate and the main principles of thermal management.

Cooling plates effectively manage temperature, enhancing battery system safety. By preventing overheating and thermal runaway events, cooling plates reduce the risk of battery fires or explosions, especially in high-stress environments like electric vehicles or grid storage systems. source: RSC Adv., 2017, 7, 14360-14371

Sogefi offers a full range of innovative battery cold plate solutions to meet the diverse needs of EV battery pack architectures. Laser welded extruded designs, and laser welded cold plates are produced with a fraction of the energy consumption compared to the traditional brazed or roll bond cold plates.

The serpentine design increases the contact area between the cooling fluid and the battery cells, promoting efficient heat transfer. The cooling plate's thermally conductive material provides heat to move away from the battery cells. When heat is generated within the battery during operation, it naturally flows towards areas of lower temperature.

Cold Plates provide localized cooling of devices by transferring heat from the device to a liquid that flows to a remote heat exchanger, which dissipates heat, for instance, via air cooling and fans.
