Fire Safety Challenges with EV Charging Stations in Commercial Real Estate

Introduction

Fire safety is paramount to business continuity planning for commercial real estate (CRE) professionals. As technology evolves and new challenges arise, staying abreast of the latest fire solutions is crucial to protect tenants, assets, and maintain operations. This report delves into fire safety challenges and solutions, with a focus on the increasing presence of electric vehicle (EV) charging stations in commercial properties and emerging technologies that can bolster fire safety and business continuity.

Fire Safety Challenges with EV Charging Stations

The growing popularity of electric vehicles has spurred a surge in the installation of EV charging stations in commercial properties. While offering convenience to tenants and supporting sustainability initiatives, these charging stations present unique fire safety challenges ¹.

Fire Risks

Lithium-ion batteries, commonly used in EVs, pose a significant fire risk due to their high energy density. If a malfunction or thermal runaway occurs, these batteries can ignite and release substantial heat, leading to intense fires that are difficult to extinguish ³. This risk is heightened in confined spaces like parking garages, where fires can spread rapidly and cause extensive damage ¹.

Several factors influence the hazard level associated with EV fires in parking garages. These include the type of vehicle (e.g., hybrid, electric), the vehicle's condition (e.g., age, presence of open windows), whether the vehicle is charging, the ignition source and location of the battery, and the potential for re-ignition ⁴. For instance, fires originating underneath the chassis of a car are more challenging to access and extinguish compared to fires in the truck, cabin, or hood ⁴.

To illustrate these risks, consider the following hazard chart:

Structural Concerns

The weight of EVs can also strain parking facilities. Some older structures may not be designed to handle the increased load of multiple EVs, potentially leading to structural damage or collapse in the event of a fire ¹.

Vandalism and Theft

EV charging stations, particularly those with valuable copper wiring, are susceptible to vandalism and theft. Damaged or inoperable stations can disrupt operations and inconvenience tenants ¹.

Fire Solutions for EV Charging Stations

To mitigate the fire risks associated with EV charging stations, CRE professionals should consider the following solutions:

Robust Fire Safety Measures

• Ensure charging stations are equipped with robust fire safety measures, such as fire detection and suppression systems specifically designed for EV charging environments ¹.
• Install charging stations with adequate electrical wiring that meets EV charging requirements and is compatible with the equipment's technical specifications ².
• Provide a dedicated circuit for the charging station to prevent overloading and potential fire hazards ².
• Incorporate Knox Remote Power Boxes adjacent to EV charging stations. These boxes allow emergency responders to immediately power down chargers in emergencies ⁵.
• Ensure that charging equipment includes safety features such as In-Cable Control Boxes (ICCB) to protect against overcurrent and undercurrent, ground monitoring systems to prevent electric shock and fire, and temperature control sensors to monitor for excessive heat and shut down power if necessary ⁶.

Strategic Placement and Design

• Locate charging stations in open or surface areas away from buildings to minimize fire spread ¹.
• Use fire-resistant materials in the construction of charging stations and surrounding areas.
• Separate EV charging points to limit fire spread and ensure adequate space for firefighting equipment.

Advanced Suppression Technologies

It is crucial to recognize that lithium-ion battery fires behave differently than conventional fires and require specialized extinguishing agents and tactics ³. Therefore, consider the following solutions:

• Specialized extinguishing agents like aerosols or clean agents that can effectively suppress lithium-ion battery fires.
• Localized suppression systems for targeted protection of charging stations and surrounding areas.

Emerging Technologies and Fire Solutions for CRE Professionals
