On December 5, 2024, Denise Graovac from Thames Ditton, Surrey, was shocked when her handheld vacuum cleaner exploded while charging in her garage. She had left the device unattended while it was plugged in, and her daughter suddenly heard a loud bang. The explosion caused a fire that rapidly spread, with the vacuum cleaner melting completely. Thankfully, the fire was contained before it could cause more severe damage, but the property loss is estimated at $5,000.

Surrey Fire and Rescue Service (SFRS) responded to the fire and confirmed that the explosion was likely caused by the lithium-ion battery in the vacuum cleaner. Lithium-ion batteries, which are commonly used in household items such as smartphones, laptops, e-bikes, and vacuum cleaners, can become a fire hazard if mishandled, damaged, or charged improperly. In this case, the vacuum cleaner, which had been left charging without supervision, posed a serious risk.

According to SFRS, this incident is part of a worrying trend: the number of battery-related fires has risen sharply over the past few years. Since September 2024 alone, there have been 55 reported incidents, a significant increase from previous years — 53 incidents in all of 2023, 20 in 2022, and just 13 in 2021.

Lithium-ion batteries, though widely used, can pose serious risks if they are damaged, overcharged, or improperly disposed of. The explosion in Graovac’s garage is a stark reminder of how these devices can fail unpredictably, sometimes leading to catastrophic fires. “Be very careful what you leave plugged in,” Graovac warned. “They can explode at any time and they can cause loss of property and even possibly loss of life.”

The unpredictability of lithium-ion battery malfunctions, such as spontaneous combustion, makes it essential for homeowners to be vigilant when using such devices. As a precaution, devices should not be left charging unattended, especially in enclosed spaces like garages, where a fire could spread unnoticed.

This incident highlights the critical need for early fire detection and rapid response systems in homes, especially when using devices powered by lithium-ion batteries. Planck Vision Systems, with its cutting-edge thermal imaging technology, can play a vital role in identifying potential fire risks before they escalate.

By detecting minute temperature variations, Planck Vision Systems’ always-on monitoring ensures that any abnormal heating is caught early, allowing for timely intervention and preventing larger-scale damage. Early detection can be the difference between a small, controllable fire and a devastating loss of property or life.

As we rely more on lithium-ion battery-powered devices, it is essential to be aware of the potential hazards they pose. Graovac’s experience serves as an important reminder to safely manage battery-powered devices, especially when charging. The rise in battery-related fires in Surrey underscores the need for continued education and better fire safety measures in homes.
