Batería doméstica Fire Safety: Facts vs Myths

Are baterías domésticas safe?

The short answer: yes, modern baterías domésticas with LFP technology are very safe. Yet there are concerns, often fuelled by news reports about fires involving e-bikes or cheap Chinese batteries. These concerns are understandable, but it is important to distinguish between the different battery technologies and quality levels.

In this article, we separate facts from myths, examine the statistics, and explain which certifications and safety measures matter.

LFP vs NMC: the safety difference

The type of battery chemistry is the most important factor for safety. There are two main types in baterías domésticas:

LFP (Lithium Iron Phosphate) — very safe

LFP batteries (LiFePO4) are the safest lithium batteries available. They are thermally stable up to 270°C and are inherently non-flammable. There is no oxygen present in the cathode, making thermal runaway (the chain reaction that leads to fire) virtually impossible. All baterías domésticas sold by HES use LFP technology.

NMC (Nickel Manganese Cobalt) — less safe

NMC batteries are still used in some older batería doméstica models and vehículo eléctricos. They have a higher densidad energética but are less thermally stable. When overheated (above 150°C), thermal runaway can occur. The probability is low with good protection systems, but the risk is greater than with LFP.

Which certifications are important?

Never buy a batería doméstica without the proper certifications. These are the standards to look out for:

• IEC 62619: the international standard for the safety of lithium batteries in stationary applications. Tests for short circuit, overload, drop and fire.
• UN 38.3: mandatory for the transport of lithium batteries. Tests for extreme temperatures, vibrations and altitude differences.
• CE marking: mandatory for sale in the EU. Garantías conformity with European safety standards.
• TÜV certification: additional independent testing by TÜV Rheinland or TÜV SÜD. Extra confidence in safety.
• IP65/IP67: protection rating against dust and water. Important for outdoor systems.

Fire statistics: the facts

Let us look at the numbers. In los Países Bajos, as of 2026, more than 100,000 baterías domésticas have been installed. The number of fire incidents involving baterías domésticas is:

Not a single incident involved a certified LFP battery from a reputable brand. All incidents were related to NMC chemistry or non-certified products. The risk of fire with a certified LFP batería doméstica is comparable to that of a fridge or washing machine.

Guidelines from the Dutch fire service

The Dutch Fire Service published guidelines in 2025 for the safe placement of baterías domésticas. The key recommendations:

• Do not place the battery in a bedroom or near the only escape route
• Ensure ventilation: at least 10 cm of space around the battery for air circulation
• Install a smoke detector in the room where the battery is located
• Choose a certified product: CE marking and IEC 62619 are the minimum

Seguro aspects

Most building insurers cover baterías domésticas without an additional premium, provided the product is certified and correctly installed. It is advisable to inform your insurer about the placement. Some insurers request the certification number.

For plug & play systems, the battery typically falls under your contents seguro. Check your policy or contact your insurer for confirmation.

Conclusion

Baterías domésticas with LFP technology and the proper certifications are exceptionally safe. The statistics speak for themselves: not a single incident with certified LFP batteries in los Países Bajos. The myths surrounding riesgo de incendio are largely based on incidents with other battery types (NMC) or non-certified products.
