Milvent Venting+Valveprotects the battery pack Allow release of excess pressurewithin the full EV battery pack enclosure With the development of electronic products and new energy vehicles, consumers have an increasing demand for power supply and energy storage, and have a higher and higher demand for environmental protection new energy products.

What is a battery vent valve?

“Our new battery vent valve is designed to enable rapid overpressure release in the battery pack.” A battery pack thermal runaway situation can occur when individual cells inside the unit fail due to physical impact or short circuit.

Does Eaton have a dual-stage battery pack vent valve?

Eaton plans to add new technologies to its battery safety offerings, including a dual-stage valve that incorporates all the features of the single-stage version as well as humidity management solutions for inside EV battery packs. Learn more about Eaton’s single-stage battery pack vent valve.

How can mechanical design and battery packaging protect EV batteries?

Robust mechanical design and battery packaging can provide greater degree of protection against all of these. This chapter discusses design elements like thermal barrier and gas exhaust mechanism that can be integrated into battery packaging to mitigate the high safety risks associated with failure of an electric vehicle (EV) battery pack.

What is a single-stage vent valve for EV batteries?

Power management company Eaton announced its eMobility business has introduced a single-stage vent valve for electrified vehicle (EV) batteries. The valve acts as an overpressure relief for the vehicle’s battery pack. “As the electrified vehicle market continues to grow, battery packs are becoming progressively more powerful and create more heat.

Does a dual-stage battery pack need venting?

With venting a necessity in battery pack design, dual-stage venting efficiently provides both passive and active venting in one assembly. Proper venting, however, requires careful planning and integration in the overall process, and should not be treated as an afterthought.
