Safe storage of e-bike batteries in fireproof boxes, containers and bags

The share of e-bikes and pedelecs in the number of bicycles sold is increasing all the time and what used to be the preserve of the older generation now knows no age limit. Even mountain bikes, racing bikes and much more are becoming increasingly popular as battery-powered versions. What many owners of e-bikes and pedelecs often forget: With the e-bike battery, you not only get a "built-in tailwind", but also a high-performance power pack with a high energy density that reacts sensitively if stored incorrectly or handled carelessly. Quite a few e-bike batteries have already caused fires and extinguishing battery fires is often problematic. Accordingly, e-bike batteries should be stored safely and properly in order to minimize the dangers of a lithium battery from the outset.

Suitable storage boxes and bags for e-bike batteries

With the right container, you not only increase the service life of the battery by protecting it from environmental influences, but you also directly reduce the risk of fire that can be caused by an e-bike battery or the dangers that arise for people and the environment if an e-bike battery explodes.

Simple battery bag or robust battery storage box?

If you are looking for a suitable storage option, you will quickly come across two options: On the one hand, relatively inexpensive battery bags are on offer. However, these primarily serve as a simple packaging option and protect the battery from external influences such as weather or dirt. However, these bags generally cannot provide fire protection in the event of a battery defect or the necessary safety from the dangers of a Li-ion battery, or only inadequately. In this case, special storage boxes for e-bike batteries should be used, which are equipped with appropriate granules to ensure safe storage. It is also advisable to have a suitable battery fire extinguisher to hand so that you can take immediate countermeasures in the event of a battery fire.

The common storage options for e-bike batteries are presented below:

• Storage boxes for e-bike batteries
• Fireproof battery bags

Storage boxes for e-bike batteries

Depending on the type of battery to be stored and the number of e-bikes whose lithium batteries are to be stored, different boxes and crates are available. The Zarges K470 battery safe is an established classic in this area, but other manufacturers also offer suitable storage boxes, such as Genius with the Lio-Guard boxes or Priorit with the Priopack battery storage container.

• B&W LI-ION CARRY & STORE transport case type 6040 for e-bike batteries
• Genius Lio Guard boxes for e-bike batteries
• Priorit Priopack boxes for e-bike batteries
• ZARGES K 470 - Battery safe for e-bike batteries

B&W LI-ION CARRY & STORE transport case type 6040 for e-bike batteries

The LI-ION CARRY & STORE e-bike battery case from B&W has been specially developed for storing e-bike batteries, although it can also be used for storing and transporting other lithium-ion batteries. The internal dimensions of the battery case are designed to easily store two standard-sized e-bike batteries in the battery box. Private users in particular are increasingly looking for a safe, easy-to-use and attractively priced option for storing e-bike batteries. With the LI-ION CARRY & STORE Type 6040 transport case, B&W has now created the opportunity to guarantee this in the private sector. In addition to private users, LI-ION CARRY & STORE battery transport cases are also used in the commercial sector, e.g. by bicycle dealers, who use this storage container to ensure safe transportation when delivering individual e-bike batteries, for example. The Cirrux cushions supplied provide the e-bike batteries with both mechanical protection against impact and a fire-retardant effect in the event of problems with the battery.

Genius Lio Guard boxes for e-bike batteries

The battery boxes from Genius offer the right solution for many applications: available in different sizes and equipped with the well-known Pyrobubbles, they can be used to store e-bike batteries of different types and capacities. The Genius battery boxes are also very attractively priced and are therefore very popular with both commercial and private users.

Priorit Priopack boxes for e-bike batteries

The Priorit boxes are designed in a similar way to the Genius boxes and combine great flexibility with a high level of reliability and safety for storing e-bike batteries. With the specially developed Priopack filling agents, they offer comprehensive protection against the dangers that can emanate from an e-bike battery.

ZARGES K 470 - Battery safe for e-bike batteries

The K470 battery safe from Zarges is an established classic in the field of battery storage in general and also specifically for e-bike batteries. Similar to the LI-ION Carry & STORE battery case from B&W described above, the battery safe from Zarges is used by both private individuals and bicycle dealers to store and transport e-bike batteries in order to minimize the potential dangers posed by these energy cells. Zarges uses Cirrux cushions to equip the fireproof e-bike battery box. This specially developed, fire-resistant cushioning and absorbent material made of textured glass fibers safely embeds the e-bike batteries packed in it and can have a fire-retardant effect in the event of a battery fire. Leaking liquids are also absorbed.

High-quality battery bags for e-bike batteries

In addition to the inexpensive battery bags without dedicated fire protection, there are also special bags for e-bike batteries that are made from high-quality, fire-retardant fabric. In many cases, these are an attractively priced alternative to the often rather expensive storage boxes and containers for e-bike batteries, especially for private individuals.

Important parameters for the safe storage of e-bike batteries

Three factors play a particularly important role when storing e-bike batteries over a longer period of time, as they have a significant influence on the integrity and performance retention of a lithium-ion battery:

1. The temperature at which the battery is stored - ideally between 5 and 20°C
2. The charge level of the battery - ideally between 30 and 60%
3. Protection from environmental influences - dry and protected from the weather

Optimal temperature for storing e-bike batteries - between 5 and 20°C

The best temperature range for storing a Li-ion battery is between 5-20°C. In winter, when batteries are often stored over a longer period of time, care should be taken to ensure that they are no longer stored outside in very cold temperatures, but in a cellar room, for example. The same applies in summer: If the temperatures in the garage or where the e-bike is parked rise sharply or if the battery may even be exposed to direct sunlight (which should be avoided at all costs), the battery should also be stored in the cellar. It is advisable to use suitable storage containers for e-bike batteries to minimize the risk to the environment in the event of problems.

The ideal charge level for stored e-bike batteries - between 30 and 60%

If you are planning to store an e-bike or pedelec battery for a longer period of time, for example over the winter, you should also keep an eye on the battery's state of charge in addition to the temperature described above. Ideally, a battery should not be completely discharged, nor should it have a full charge. With heavily discharged batteries, there is a risk of deep discharge, which can lead to battery damage; with (almost) fully charged batteries, possible battery problems lead to much stronger thermal reactions than with weakly charged batteries. In general, a charge level of 30-60% is considered optimal. Regardless of the state of charge, it is also highly recommended to store the e-bike in a suitable storage container.

Protection against environmental influences - dry and protected from the weather

The third important factor in the proper and safe storage of e-bike batteries is protection from the weather. Moisture / humidity in particular can damage an e-bike battery and should therefore be avoided at all costs during long-term storage. Common storage containers such as the Zarges battery safe or the B&W LI-ION CARRY & STORE transport case type 6040 provide efficient protection for the Li-ion batteries, even if the environment is not always completely dry. Even storage in a garage or a basement with a tendency to moisture does not always provide optimum storage conditions, but these can be significantly improved with the appropriate storage boxes, thus extending the service life of the battery. Protection against mechanical shocks is also a relevant point that should not be ignored when storing batteries.

Fire protection when storing e-bike batteries

The proper and safe storage of e-bike batteries not only serves to protect against a loss of performance with regard to the capacity of the battery (and thus the range of the e-bike / pedelec), but fire protection is at least as important in this context, as it can also significantly reduce the risk of fire from an e-bike battery. Even without external influences, incorrect storage over a longer period of time can lead to damage to the energy cells and thus pose a potential danger that can even lead to fire and explosion of the e-bike battery.

Fireproof boxes for e-bike batteries

Accordingly, in addition to the correct temperature, the optimum state of charge and protection from the weather, fire protection is also an important part of the safe storage of e-bike batteries, which can be ensured in particular by using the right storage containers / storage boxes. We therefore recommend fireproof

Fireproof boxes for e-bike batteries

Accordingly, in addition to the correct temperature, the optimum state of charge and protection from the weather, fire protection is also an important part of the safe storage of e-bike batteries, which can be ensured in particular by using the right storage containers / storage boxes. It is therefore advisable to use fireproof or fire-retardant boxes and containers for e-bike batteries in order to slow down or completely prevent the spread of fire in the event of a fire. With the various battery storage containers, however, the entire boxes/crates are not always fireproof, but the fire-retardant effect is usually ensured by using different extinguishing granulates (such as Pyrobubbles, Cirrux cushions or Extover). This means that even e-bike battery boxes made of plastic are a good substitute for completely fireproof boxes, such as the Zarges K470 battery safe made of aluminum.

Have an additional battery fire extinguisher to hand

In order to be able to take quick countermeasures in the rare event of a battery fire, it is also advisable to have a lithium fire extinguisher to hand, which can quickly contain a possible fire with small and medium-sized Li-ion batteries (which also include the energy storage systems of e-bikes and pedelecs).

Dimensions and capacity of e-bike batteries

If you are looking for a safe storage option for your e-bike or pedelec battery, two criteria are particularly important: On the one hand, the battery must fit into the container, so you need to keep an eye on the dimensions of the battery in question when buying a battery box or storage box. The capacity of the battery is just as important: in order to be protected against fire or other problems, the energy absorption of the battery is of great importance, because the more powerful a Li-ion battery is, the greater the potential dangers and the battery boxes or their safety mechanisms must be dimensioned accordingly.

Triple protection with e-bike battery boxes

In order to store the Li-ion batteries of an e-bike safely, the storage containers should fulfill a number of characteristics. On the one hand, they should protect the e-bike batteries from possible influences that could damage the battery and thus impair its function. At the same time, however, the containers should also protect the surroundings in the event of problems with the battery itself, e.g. in the form of a battery fire.

Protection against mechanical shocks / external forces

Lithium-ion batteries are normally designed to be relatively robust, and e-bike batteries in particular have to withstand the odd knock or two in normal everyday life when they are used on a bike. Nevertheless, problems can occur with lithium batteries if they are accidentally dropped or are subjected to strong mechanical impacts for other reasons. Mechanical damage is a source of danger for batteries, which should be avoided with correct storage. Accordingly, an important feature of containers and boxes for e-bike batteries is protection against mechanical damage. This is usually achieved by padded storage of the batteries. If the batteries are stored in the Zarges battery safe or the B&W LI-ION CARRY & STORE Type 6040, for example, they are protected from external mechanical impacts by the container itself and if, for example, the container itself should fall, the Cirrux cushions used ensure that only a small proportion of the forces acting on the battery are passed on to the battery and it therefore remains intact.

Protection from the elements

In addition to protection against external forces, the storage containers also offer a certain degree of protection against the effects of weather / improper storage. E-bike batteries should not be stored at temperatures that are too high or too low and should also be protected from moisture. If a battery is not being used and actively charged, it should therefore be stored in a suitable container in the garage or cellar, for example, so that the conditions for safe storage are met. On the one hand, the temperature window is then correct and the battery cases also provide protection against moisture.

Protection for the environment in the event of battery problems

While the first two properties of the containers relate to the protection of the e-bike battery, the third mechanism protects the environment in the event of problems with the e-bike battery. Time and again you read in the press that entire house fires are caused by e-bike batteries - these dangers are to be averted with the storage containers. Specially developed cushions with fire-retardant granules or fibers inside the boxes nip any battery fires in the bud. Here, the manufacturers Zarges and B&W use Cirrux cushions in the battery containers, Priorit uses Priopack filling material and the manufacturer Genius uses its own Pyrobubbles cushions.
