The benefit of electric vehicles (EVs) being efficient while exceeding customers' demands is quickly revolutionizing the automotive industry. The battery component of the vehicle is the main difference from traditional internal combustion engine (ICE) vehicles. Battery packs create a variety of safety hurdles to overcome during everyday use, such as pressure during rapid charging, extreme temperatures, and internal malfunctions. These events generate excessive heat or gas that the equalization membranes cannot expel in a timely manner. The Pressure Relief Valve activates to help reduce the risk of fire or explosion and damage to the battery by promptly releasing the pressure and protecting the occupants.
Many battery packs have a ventilation design with many small PRVs on the same pack. These ventilation systems have low, inconsistent flow, which could lead to greater risk to the vehicle, occupants, and first responders. These systems also have more imprecise opening pressure, which is a significant disadvantage to OEMs. Not having quality data and poor output sets back advancement in innovations and EVs.
At Nifco, we live by the principle that “safety is non-negotiable.” This commitment drives the innovation behind every product we develop, especially those safeguarding the integrity of vehicle battery systems and the safety of their occupants.
Our battery vent valve, also known as a pressure relief valve, is purpose-built to release excess pressure within the battery pack in a controlled and efficient manner. This proactive response helps prevent catastrophic failures and enhances the overall resilience of electric vehicles.
Engineered with lightweight, heat-resistant resin, our injection-molded design not only boosts functionality but also cuts down on cost and weight. The high-flow architecture of the ventilation valve allows for rapid evacuation of harmful gases during thermal runaway events, ensuring your EV systems remain stable under the most demanding conditions.
Whether you refer to it as a battery pack vent, an emergency vent valve, or simply the smartest safety solution on the market, Nifco’s design stands out with its compact form and reduced component count.
