S-TYPE HV · DIRECT BATTERY FIRE PROTECTION

A battery fire containment blanket is not simply a smaller vehicle fire containment blanket

With a vehicle fire containment blanket, the vehicle structure typically remains between the traction battery and the blanket. With an HV battery fire containment blanket, the situation is fundamentally different: the blanket is designed for use directly on or immediately above lithium-ion, high-voltage and traction batteries.

In the event of a thermal runaway, the fire containment blanket is therefore exposed much more directly to the effects of the battery event. In addition to extreme temperatures and flames, directed jet flames and hot gas streams, hot particles, pressure pulses as well as mechanical and kinetic loads caused by rupturing cells and ejected components may act directly on the textile protection system.

This is why Fingerhuth uses a reinforced heavy-duty design for the S-TYPE HV. The underlying material principle remains the same: high-temperature-resistant silica fabric with a mineral vermiculite coating on both sides. However, the substantially heavier construction provides significantly greater mechanical reserves for direct battery applications.

The S-TYPE HV has therefore been specifically developed for applications in which the blanket must withstand thermal, mechanical and kinetic loads as directly as possible while limiting the spread of fire, flames and hot particles to the surrounding area.

HEAVY DUTY

Reinforced S-TYPE material for direct contact with battery systems

The S-TYPE HV is based on the same high-temperature-resistant material principle as our vehicle fire containment blankets, but uses a significantly heavier and more robust construction of approximately 1,150 g/m².

The material consists of high-temperature-resistant silica fabric with a mineral vermiculite coating on both sides. Its thermal performance remains exceptionally high: up to 1,200 °C continuous temperature and up to 1,600 °C short-term peak temperature.

The increased material weight particularly improves mechanical stability and energy absorption. This is crucial because, in direct battery applications, the fabric is not shielded by a vehicle body or other structural components and may therefore be directly exposed to the effects of a thermal runaway.

The additional material mass also helps the blanket remain as stable as possible on the battery system during pressure pulses and explosive battery events.

HV battery thermal runaway with jet flames, hot particles and mechanical loads

JET FLAMES · HOT PARTICLES · MECHANICAL LOADS

Designed for loads that are typically shielded by the vehicle structure in vehicle fire blanket applications

During a thermal runaway, individual cells or battery modules can release directed streams of hot gases and particles. These jet flames and hot gas streams can locally impact the fire containment blanket positioned directly above the battery with extremely high temperatures and velocities.

In addition, cell housings, module components and other parts may be accelerated by pressure events and strike the textile protection system. The S-TYPE HV is therefore designed not only for extreme thermal exposure but also for increased mechanical and kinetic loads.

The heavy-duty material construction is designed to help absorb localised load peaks, reduce the risk of material penetration and limit the spread of hot particles and flames into the surrounding area.

At the same time, a high degree of inherent stability is essential: even during dynamic battery fire events, the fire containment blanket should remain on the battery system as securely as possible and maintain the defined containment area.

GAS MANAGEMENT · WATER PERMEABILITY

Heavy duty – without sacrificing the proven porous material structure

Despite its significantly higher material weight, the characteristic porous and gas-permeable structure of the S-TYPE material system is retained. Smoke, pyrolysis gases and reaction gases can therefore escape through the surface of the fire containment blanket.

This reduces the risk of a critical accumulation of flammable pyrolysis gases beneath the blanket. At the same time, the gas-permeable structure counteracts excessive ballooning of the fire containment blanket and helps maintain close contact with the battery system.

Water permeability is also retained. Extinguishing or sprinkler water can penetrate the textile structure or be absorbed and distributed by the material. This can support cooling of the blanket, accessible battery surfaces and the immediate surrounding area.
