2 Lithium-ion batteries LITHIUM-ION BATTERIES – HOW PROFESSIONALS AND INSURERS RECOMMEND HANDLING BATTERIES Ever more fequently, private individuals, tradespeople, and companies are using lithium-ion batteries classified as being in the moderate performance class according to VdS 3103. It is important to keep safety in mind when doing so. If you do not store and/or charge these batteries properly, they can pose hazards and safety risks. Insurers, associations, and professionals have drawn attention to this issue. Property insurers recommend using available protective equipment (such as type 90 safety storage cabinets) to minimise risks and avoid damage. Property insurers recommend the use of safety storage cabinets for the following reasons: “If lithium ion batteries are required at production facilities, then measures and safety precautions such as (...) storing them in fire-resistant cabinets should be considered”. IMK Ber. No. 192 Dipl.-Ing. Jürgen Kunkelmann Section 2.2, last updated 10/2017 “Lithium batteries should generally be treated as a hazardous material.” Publication VdS 3103 : 2019-06 (03) General Association of the German Insurance Industry published by VdS Schadenverhütung GmbH "Areas with medium power batteries should be spatially (at least 5 m) or structurally separated from other areas with fire-resistant structures.” Publication VdS 3103 : 2019-06 (03) General Association of the German Insurance Industry published by VdS Schadenverhütung GmbH “Fire-resistant safety storage cabinets (type 90) with smoke detector monitoring offer particular protection, as batteries can be both stored and charged there in a protected manner. “ Provinzial Flyer – E-Bikes handling lithium safely, last updated 06/2020 “Past damage we have seen has shown that damaged or defective batteries, in particular, can cause a fire. We have also seen fires caused by lithium-ion batteries in bicycle stores”. Provinzial - Handling lithium-ion batteries safely in bicycle sales, www.provinzial.de last updated May 2020 “Larger quantities, or more powerful LIB must be stored at a safe distance from flammable materials. If they are stored inside buildings, then a clearance of 2.5m from other goods must be maintained, or the LIB must be stored in a separate area secured by fire protection technology (like a safety storage cabinet or container)!” LIB= Lithium-ion batteries DGUV Information 205-041 Fire protection when handling lithium-ion batteries Last updated 02/2024 "Use of a charging cabinet or a separate room with fire protection, if more than 5 batteries are present."

Handle batteries properly and appropriately to reduce hazards such as the risk of fire. Lithium-ion batteries offer many advantages. They are long-lasting, offer high energy density, have a low level of self-discharge, and can be used in a wide range of different applications. Using lithium-ion batteries is safe. However, according to the VDE they are safe only when handled properly. Technical defects or improper handling can cause a fire. If a lithium-ion battery discharges its energy in an uncontrolled manner, the heat released may exceed the melting point of the lithium. This will result in a chain reaction. Professionals call this “thermal runaway”. The battery can explode as it burns. Because of this, it is important to understand and comply with the safety regulations for moderate performance batteries. It is best to store and charge lithium-ion batteries in an asecos safety storage cabinet.
5 Store and charge lithium-ion batteries in a safety storage cabinet! Comply with the manufacturer’s specifications, and follow the information provided on technical product sheets. Protect the poles of the batteries from short circuiting. Protect the batteries from mechanical damage. Do not expose the batteries directly or continuously to high temperatures or heat sources, such as direct sunlight Store the batteries in a location structurally or spatially separate from other flammable materials if there is no automatic extinguishing system available: minimum distance 2.5 m Use of a charging cabinet or a separate room with fire protection, if more than 5 batteries are present Remove damaged or defective batteries from your warehouse and production areas immediately; store them temporarily until their disposal at a safe distance away, or in an area separated using fire protection technology. Only store batteries that have a testing certificate in accordance with UN 38.3; store prototypes only in exceptional cases and with a risk assessment. Only store batteries in separate, fire-resistant areas or at a safe distance of 5 m Do not store batteries with other products that can act as accelerants to a fire Monitor the storage areas where your batteries are located using suitable sensors with connection to a permanently staffed alarm receiving office With fire extinguishing systems, observe the information in the product data sheets for the batteries on suitable extinguishing agents.

At least the fire suppression unit and smoke detector must be exchanged before doing so. ION-LINE OUR asecos ION-LINE SAFETY CONCEPT ION-LINE safety storage cabinets offer you the safety you need for storing and charging lithium-ion batteries. The CORE, PRO and ULTRA models immediately detect any fires that occur in the cabinet. This allows employees to evacuate the building quickly if an alarm sounds. Resulting from the connection to a permanently manned building control system, rescue services can: • to receive an alarm and be on site quickly. • to immediately take further measures, for instance evacuating the building, to minimise subsequent damage caused by smoke or extinguishing water. ION-LINE cabinets are equipped with a transport base and quick-release power supply for safe evacuation. When the cabinet is removed from the setup location, this plug connection disconnects independently.
9 Complementary option 1: Relay module (available optionally) for alarm differentiation in 4 levels Serial equipment: Potential-free alarm contact reports a collective alarm Complementary option 2: Remote signal module (available optionally) for alarm forwarding via mobile network Control centre or permanently occupied post (internal or external) Alarm forwarding – These are your options: max. 5 freely selectable phone numbers ALARM FORWARDING AS KEY COMPONENT Whenever the cabinet is unattended, especially at night or on weekends, alarm forwarding is indispensable in an emergency. It is the only way to quickly detect the damage and initiate countermeasures. Manufacturer recommendation & series equipment: POTENTIAL-FREE SWITCHING CONTACT All ION-LINE cabinets are equipped at the factory with a potential-free switch contact for forwarding the alarm on site within the building. The most reliable way to transmit the alarm is to connect this contact to a continuously staffed control centre (internal or external). Optional modules can be purchased as an alternative or extension to this system. Complementary option 1: RELAY MODULE By choosing this option, you are opting for alarm differentiation instead of a collective alarm. The factory-installed module differentiates between four different warning and alarm levels: • warning message at a temperature above 50 °C inside the cabinet • alarm level 1 • alarm level 2 • power failure Via potential-free alarm contacts, these signals are passed on to a central control centre. With the clear differentiation of the alarm conditions, you can initiate optimally coordinated measures. The relay module is suited for the PRO models of the IONLINE. Order No. 38766 Complementary option 2: MODULE FOR REMOTE SIGNALLING The module offers an alarm forwarding via the mobile phone network (SMS/call) and is therefore especially suitable for companies and facilities without a central building management system. In an emergency, the immediate alerting of one or several defined persons is triggered. The module is easily installed on-site by the customer via plug (also suitable for retrofitting) and offers the following functions: • five programmable telephone numbers • configurable message texts • collective alarm in case of an emergency or power failure A SIM card is required for the initial operation of the module, which must be provided by the customer. Alternatively, the included SIM card (for European and UK use only) can be activated via an online portal. A good mobile phone connection is necessary to ensure that the signal can be transmitted. The remote signalling module is suited for all ION-LINE models. Order No. EU-Version 38765
