Thermal Management

Simulate battery cooling systems for modules or packs

Simscape™ Battery™ includes blocks and models of battery cooling systems for simulations of battery thermal management. You can use these blocks to add detailed thermal boundary conditions and thermal interfaces to the battery Module or ParallelAssembly blocks. These cooling system blocks contain both thermal and thermal-liquid domain connections. Use the thermal domain nodes to interface to or from battery blocks that include a thermal model. Use the thermal-liquid domain nodes to specify coolant inlet and outlet properties and operating conditions.

The cooling system blocks in this library are flat cooling plates. These blocks support three main flow configurations: parallel channels, U-shaped rectangular channels, and edge cooling. In the edge cooling configuration, the coolant flows at one end of the flat plate and all the heat from the battery cells is transferred via conduction within the cooling plate material. You can discretize these cooling plates into elements to closely capture temperature spreads resulting from the dynamic interaction with the battery and the coolant flow.
