Hyundai, Kia Patent Grid-Based Cooling Case for EV Batteries
Hyundai and Kia have created a new design for electric vehicle batteries that helps prevent fires.
The design uses a special cooling system that looks like a grid, which spreads coolant evenly across the battery.
This helps keep the battery cool and safe.
The cooling system is built into the battery's case, making it stronger and more durable.
This new design is expected to be used in electric vehicles within the next two years.
It's important because it makes electric vehicles safer and more reliable, which is good for both consumers and the environment.
Hyundai and Kia have patented a new EV battery design with a grid-based cooling system.
The cooling system uses intersecting sub-channels for even coolant distribution.
The design integrates cooling channels into the battery's lower case, eliminating the need for separate cooling plates.
This integration enhances structural strength and improves cooling efficiency.
The patent was filed in November 2024 and is expected to be integrated into EV platforms within two years.
