While a battery stores energy, a converter converts that energy into an alternative form for different applications.
Both of them generate heat during operation. Within the battery, heat is generated from the internal resistance where the flow of electric current encounters opposition on one hand, and from the chemical reaction occurring within the battery on the other. Effective thermal management is hence crucial to avoid overheating which could lead to a series hazards. Proper cooling also helps maintain the reliability of inverters, which are essential for converting and managing the energy flow between the battery and the motor.
During the engineering phase, MyGrid encountered a critical heating issue where the battery and inverter produced excessive heat, posing risks of component failure and potential thermal runaway-induced battery explosions.
They had three options to solve the problem.
MyGrid chose to use ColdStream, taking advantage of the Diabatix Startup Program.
Despite lacking experience with CFD, the MyGrid engineers quickly evaluated the feasability of different design ideas thanks to ColdStream’s intuitive interface. ColdStream determined that natural convection cooling system would be insufficient to cool down the inverter and that forced convection (fans) was necessary to achieve a safe operating temperature.
The plaform generated various cooling shapes and systems based on MyGrid’s inverter and battery and the team also used ColdStream to optimize the positioning of its fans for effective cooling. ColdStream helped MyGrid keeping their focus on product and market development while addressing thermal management simultaneously with minimal effort.
