Modern electric vehicle (EV) batteries are powerful but come with major drawbacks: they’re bulky, expensive, difficult to recycle, and risky—capable of catching fire or exploding during short circuits or electrical surges like lightning. The increasing energy density only makes these problems worse. Current systems lack efficient safety mechanisms, are hard to cool, and are overly complex to maintain or replace.
The Invention
This invention introduces a smarter high-voltage battery module designed to solve these challenges. It uses compact, disk-like battery cells stacked in a common casing—eliminating the need for heavy metal housings. Each module has built-in surge protection using a specialized electrical component called a varistor. Cooling is handled by channels for fluids or gases that run directly through the battery core. Importantly, the battery cells are designed with limited individual capacity, which dramatically lowers the risk of fires.
What’s New and Different
Instead of giving each battery cell its own complicated protection, this design uses a shared protection system across the module. It virtually eliminates harmful electrical spikes and avoids the need for complex, failure-prone internal components. The battery structure also reduces internal resistance and electromagnetic stress, making it safer and longer-lasting—even in extreme conditions.
Benefits
- Reduces fire and explosion risk
- Easy to cool and maintain
- Lightweight and more recyclable
- Cheaper and simpler to replace individual modules
- Compatible with multiple types of battery chemistries
- Works reliably even when one cell fails
Broader Impact
This invention could reshape how batteries are used in EVs, submarines, drones, and energy storage—boosting safety, reducing waste, and making high-performance energy systems more accessible and sustainable.
