New technologies are being introduced into our lives on a daily basis. As part of the green wave of technologies, electric vehicles (EVs) are in high public demand and in some states, a requirement of future auto sales.
While auto manufacturers and infrastructure development companies ramp up development, insurance carriers are keeping a close eye on new exposures and unintended consequences that could arise out of these new technologies.
Since these technologies are still relatively new, loss data is not conclusive enough for actuaries to pinpoint the new risks associated with EVs and their respective charging stations. However, there are a few critical aspects industry experts say to keep in mind when assessing the risks associated with EVs.
Cyber Threats:
An increased concern for EVs Charging stations are vulnerable to cyber hacking. Electric vehicles rely on data, software, sensors, and artificial intelligence to coordinate operational systems. This connectivity comes with cybersecurity dangers from malicious attacks, hacking, data compromise and system outages. Cyber risks can differ depending on how “smart” the charger is.
For instance, if the charger can be controlled remotely an additional access point exists for malicious actors to gain access to the charging station and the vehicles it connects with. Hacking risk also varies depending on whether a charger is installed at home or a public location. Should a breach to the charger occur, the entire network could be at risk.
Garaging & Charging EVs: It’s hotter than you think!
Many homeowners are likely to keep their new electric vehicle stored in their garage. While unlikely, fires have unexpectedly occurred caused by the vehicles’ lithium-ion batters. Unlike customary internal combustion vehicles, which burn around 1000 degrees Fahrenheit, fires from EV batteries burn at temperatures around 3000 degrees. Many fire departments, especially volunteer companies, do not have the equipment, man power, or water supply to extinguish fires from EV batteries.
More alarming are the EVs that are garaged in parking structures where residents live above. Local codes may require sprinkler systems installed in such developments. However, some systems may not offer the necessary water capacity sufficient for this new exposure. Even worse, older developments may not have sprinklers altogether.
It is also worth noting, many EV battery fires have a high potential of reigniting even after being extinguished for several hours. An EV’s connections and wires from the supply to the vehicle also pose increased hazards. A widely unknown exposure is many EV batteries emit hydrogen gas when charging. This could further exacerbate the fire hazard, especially in poorly ventilated garages. Additionally, concentrations of hydrogen gas pose a life safety hazard when inhaled a greater concentration.
Charging Stations: Around the property
Charging vehicles naturally puts a higher strain on your home, building, or community association’s electrical systems. Additionally, exposure of high voltage electric shock to users when handling the cables now becomes an exposure that did not exist just a few years ago. The cables used for electric vehicles are larger and heavier than typical electric cables. These cables present a considerable tripping hazard. Poor positioning of the charging station can lead to cables being laid across pavements or to hang with the potential to cause injury and/or damage to the EV and charging apparatus.
Now What?
Most insurance carriers have not made any changes to their policy forms or appetites…yet. The insurance industry is monitoring data and how these new technologies develop. Once enough data is available and trends can be established, its only inevitable the industry will respond.
Until then, implementing a few loss control measures to prevent unforeseeable losses is in your best interest. Below are a few recommendations we have prepared to best protect your assets and community
- Check with local building codes and speak with an engineer (especially if underground or garage charging is done) to verify the structure has proper ventilation and can withstand the temperatures of an EV fire.
- Speak with your local fire department and sprinkler companies to see if they have any concerns specific to your building and location.
- Shared outdoor charging stations should be installed at least 25 feet away from buildings.
- Develop a plan in the event of an emergency should someone receives a high-voltage electric shock.
- A maintenance plan should be in place to prevent any additional concern of electrical fires.
- If it is necessary to run a cable across a walkway, look to invest in a cable protector that allows people to walk over the cable lying flat as well as protecting it from damage.
- Speak with a representative or the manufacturer of the charging station to understand how communication and data is relayed with the device, if any at all.
New technologies bring about new exposures. Time will tell how the insurance industry will react to the public’s interest of electric vehicles. Until then, monitoring the hazards, assessing the risks, and implementing practical risk management strategies will allow early adopters to enjoy the latest gadgets and software.
