EV charging station fire risk: why charging points need fire safety planning

Electric vehicle charging stations are becoming a familiar part of public car parks, motorway services, workplaces, retail sites and residential developments. As charging infrastructure grows, so does the need to plan properly for EV fire risk.

Electric vehicle fires remain relatively uncommon, but when they do happen at charging stations the consequences can escalate quickly. Vehicles may be parked close together, charging equipment uses high-voltage electricity, and the surrounding area may include pedestrians, buildings, other vehicles and critical infrastructure.

Delhi charging station fire destroys more than 100 vehicles

A major electric vehicle charging station fire in Delhi destroyed more than 100 vehicles and required seven fire engines to bring under control.

Thankfully, no-one was hurt in the blaze at the Jamia Nagar electric vehicle charging and parking station. The exact cause was still to be confirmed at the time, although firefighters reportedly mentioned a possible short circuit in one of the electric vehicle chargers.

E-rickshaws, scooters and motorcycles were irreparably damaged as the fire spread through the parking area. The incident is a clear example of how a fire at a charging location can quickly become a wider site safety issue.

Why charging stations need specific fire safety planning

In order to function efficiently, electric vehicle charging stations require high-voltage electricity. Many chargers, especially rapid and ultra-rapid chargers, are high-capacity systems that deliver a large amount of power through complex electrical infrastructure.

Charging equipment is designed with safety systems, including automatic cut-offs and protective electrical components. However, no system can remove every risk. Equipment faults, vehicle damage, battery defects, electrical issues and user behaviour can all create potential hazards.

Charging stations are also used throughout the day and night by multiple vehicles. They are often located in places where a fire could affect nearby people, parked vehicles, buildings, retail units, workshops or transport operations.

Why EV fires can escalate during charging

Charging an electric vehicle can take anything from around 30 minutes to several hours, depending on the vehicle, battery size, charger output and state of charge. During that time, the vehicle is connected to a live charging system and may be left unattended.

If an EV battery cell is damaged, defective or exposed to abnormal conditions, it can heat rapidly and trigger thermal runaway. This is a chain reaction where heat spreads from one battery cell to neighbouring cells, causing the fire to intensify and spread through the battery pack.

Once thermal runaway begins, an EV fire can be extremely difficult to control. It can produce high heat, large volumes of smoke and potentially harmful gases. In a charging-station environment, the risk is not limited to the vehicle that catches fire. Nearby vehicles, chargers, canopies, buildings and people may all be affected.

The risk of collateral damage at charging stations

One of the biggest challenges at charging locations is proximity. Vehicles may be parked close together, charging bays may sit near public walkways, and charging equipment itself can be expensive and business-critical.

If an EV catches fire at a charging station, the site operator may need to manage several risks at once:

  • fire spread to adjacent vehicles;
  • damage to charging equipment and electrical infrastructure;
  • smoke and fumes affecting the public or nearby buildings;
  • restricted access for emergency responders;
  • interruption to the charging facility or wider site operations;
  • the possibility of reignition after the initial fire is controlled.

How EV fire blankets can support charging station safety

Electric vehicle fire blankets, such as the Fire Cloak EV Fire Limitation Blanket, are designed to help contain heat, smoke and flames while emergency procedures are carried out.

At charging stations, an EV fire blanket can help reduce the risk of a fire spreading to nearby vehicles, charging points or surrounding property. It can also help create a more controlled incident area for site teams and firefighters.

The aim is not to replace emergency services or wider fire safety planning. Instead, an EV fire blanket should form part of a practical response plan that includes staff training, clear emergency procedures, suitable signage, isolation of the charging equipment and appropriate access for firefighters.

Where should charging sites keep EV fire blankets?

For charging stations, location and accessibility matter. Fire blankets should be positioned so they can be reached quickly, without requiring staff or responders to move towards unnecessary danger.

Operators should consider the layout of the site, the number of charging bays, the types of vehicles using the chargers, whether staff are present, and how emergency responders would access the area if an incident occurred.

Sites with multiple charging bays, enclosed or covered parking, retail footfall, workshops, depots or public parking areas should treat EV fire containment as part of their wider health and safety planning.

A growing infrastructure needs a stronger safety plan

The number of electric vehicle charging points will continue to rise as more drivers switch to EVs. That growth is positive, but it also means charging-site fire safety needs to mature alongside the infrastructure.

For site owners and operators, the question is not only whether an EV fire is likely, but how much damage could be caused if one happened in the wrong place at the wrong time.

With suitable planning, training and containment equipment in place, charging stations can reduce the risk of one vehicle fire becoming a much larger incident.
