FIRE PROTECTION BAGS · PRODUCT SELECTION

The right fire protection bag for your battery, device and application

Lithium-ion batteries are widely used in E-bikes, power tools, smartphones, tablets, laptops, measuring instruments and many other mobile devices. Damage, cell defects or technical failures can trigger a thermal runaway involving high temperatures, flames, hot particles and reaction gases.

Fingerhuth fire protection bags have been developed for different lithium-ion battery applications. Whether an E-bike battery needs to be charged, multiple power-tool batteries need to be stored, or complete mobile devices require protected storage and transport, specifically designed solutions are available for the respective application.

Not sure which fire protection bag is suitable for your application?

Important factors include battery type, energy content, dimensions and the intended application. In particular, it is necessary to distinguish whether batteries are only stored or transported or whether charging inside the fire protection bag is required. Our specialists will be pleased to assist you with product selection.

SELECTION GUIDE · LITHIUM-ION

Which fire protection bag is suitable for your application?

Lithium-ion batteries and battery-powered devices vary significantly in terms of dimensions, energy content, cell design and intended use. The fire protection bag should therefore be selected specifically for the respective application.

The following criteria provide guidance for the technical preselection.

01 PROTECTED ITEM

Battery or complete device?

The first question is what needs to be stored or transported with additional protection: an E-bike battery, individual replaceable or power-tool batteries, or a complete electronic device such as a laptop, tablet or measuring instrument.

02 BATTERY ENERGY

Energy content and battery size

The dimensions and energy content of a lithium-ion battery influence the potential severity of a thermal event. The fire protection bag should therefore be selected according to the specific battery size and application.

03 APPLICATION

Storage, transport or charging?

Not every fire protection bag is automatically suitable for every application. If a battery is to be charged inside the bag, the construction must be specifically designed for the charging process. Our E-bike version features a protected cable feed-through for this purpose.

04 AVAILABLE SPACE

Dimensions of the battery or device

The internal dimensions must correspond to the battery or mobile device being accommodated. This is particularly important for laptops, industrial tablets, measuring instruments and elongated E-bike batteries.

05 CAPACITY

Single battery or multiple batteries?

If several batteries are stored or transported together, separating the individual batteries can be beneficial. Our power-tool version therefore features a flexible internal compartment system.

06 APPLICATION AREA

Professional or mobile use

Workshops, service vehicles, production facilities, warehouses, technical rooms and mobile workplaces place different demands on the handling, portability and capacity of a fire protection bag.

APPLICATIONS · LITHIUM-ION BATTERIES

Fire protection bags for different battery and device applications

Lithium-ion batteries have become an integral part of professional and mobile applications. Consequently, the requirements for suitable fire protection solutions vary considerably.

Our fire protection bags cover applications ranging from E-mobility and power tools to IT equipment, measuring instruments and diagnostic devices.

01 E-MOBILITY

E-Bike and Pedelec Batteries

Fire protection solution for high-capacity E-bike and Pedelec batteries during charging, storage and transport. Suitable for private users, bicycle workshops, service departments and mobile applications.

02 TRADE & INDUSTRY

Tool and Power-Tool Batteries

For lithium-ion batteries used in cordless screwdrivers, drills, saws and other professional power tools. Particularly suitable for workshops, service vehicles and mobile workplaces.

03 IT & MOBILE DEVICES

Laptops, Tablets and Smartphones

Protected storage and transport of complete lithium-ion-powered devices such as laptops, tablets, smartphones and industrial tablets.

04 INDUSTRIAL ELECTRONICS

CONSTRUCTION · SAFETY CONCEPT

Multilayer High-Temperature Fire Protection for Lithium-Ion Batteries

During a thermal runaway event, extreme temperatures, flames, hot particles, reaction gases and mechanical loads can develop within a very short period of time. A professional fire protection bag therefore needs to provide more than basic flame resistance.

Our fire protection bags are based on multilayer high-temperature constructions using non-combustible components. Material configuration, thermal insulation, closure system and construction details are adapted to the respective application.

THERMAL BARRIER

Multilayer High-Temperature Construction

Several coordinated material layers combine high-temperature-resistant fabrics with thermally insulating layers. This helps reduce the thermal load transferred to the surrounding environment.

  • High-temperature-resistant fabric layers
  • Integrated thermal insulation
  • Developed for high thermal loads
MATERIAL SAFETY

Non-Combustible Components

The fire protection bags use non-combustible high-temperature materials, including temperature-resistant closure systems. This reduces the use of combustible components within the immediate protective construction.

  • Non-combustible high-temperature materials
  • Temperature-resistant closure systems
  • Professional technical manufacturing
THERMAL RUNAWAY

Gas Management and Pressure Loads

In addition to heat and flames, a thermal runaway generates significant quantities of hot reaction gases. The construction must therefore consider thermal and mechanical loads simultaneously.

  • Construction designed with reaction gases in mind
  • High mechanical load capacity
  • Gas management system developed by Fingerhuth
HIGH TEMPERATURE

Temperature Resistance up to 1200 °C

The high-temperature materials used are designed for severe thermal loads. Depending on the specific product design, the specified temperature resistance is up to 1200 °C continuous, with short-term peak exposure up to 1600 °C.

  • Up to 1200 °C continuous temperature resistance
  • Short-term peak exposure up to 1600 °C
  • Developed for lithium-ion fire protection applications

Effective fire protection starts with the right application assessment

The appropriate protection solution should always be selected based on the specific battery, its energy content, dimensions, application and intended use. Our specialists support you with the technical evaluation and selection of the appropriate product.
